Opis:
Green walls, along with green roofs, parks, and vertical gardens, belong to the green infrastructure of cities, which will encompass the majority of humanity in the coming decades. Green infrastructure benefits both urban residents and nature in the urban landscape, although there is no scientific consensus on the extent to which green walls, especially green facades, impact biodiversity in cities. This study examined the influence of green facades on the richness of mammals, birds, and invertebrates, considering the species and age of the plants comprising the green facade in a medium-sized city located in southwestern Poland. It was found that the implementation of green facades significantly enhances species’ biodiversity compared to non-vegetated walls. Four synanthropic bird species were nesting on green facades: Eurasian collared dove (Streptopelia decaocto), blackbird (Turdus merula), house sparrow (Passer domesticus) and woodpigeon (Columba palumbus). For the beech marten (Martes foina), the green facades are a hunting ground for birds and their eggs. This simple and effective method of creating green walls provides benefits to local wildlife by creating habitats, shelter, and foraging opportunities for selected species. However, it is difficult to determine whether green facades contribute to the formation of ecological corridors in urban environments. The study also examined the social aspect related to the establishment and maintenance of green facades on the surveyed buildings.

Opis:
Human activity has caused environmental transformations for millennia, most often driven by the desire to acquire natural resources. Unfortunately, the desire to acquire these resources in many cases results in a reduction in biodiversity, that is, a reduction in genetic diversity in a given area. In addition, the transformation of the environment results in the replacement of plant species that originally existed in a given area by other vegetation, including foreign ones. Environmental transformation can take various forms, such as agricultural intensification, the acquisition of new mining areas, or simply the occupation of more land for municipal or industrial purposes. Nor can we forget one of the most important problems of recent decades: global warming, which contributes significantly to climate change and leads to the disappearance of many plant species. The way to reduce the negative human impact is to carry out environmental protection activities, both passive and active. In this paper, we take a closer look at how in vitro cultures of plants can benefit biodiversity conservation thanks to the possibility of micropropagation and long-term storage of plants.

Opis:
Previously, only three Candelariella species were known from Antarctica: C. aurella, C. flava and C. vitellina. After morphologically and phylogenetically examining our collections on soil from James Ross Island, located in the north-east Antarctic Peninsula region, and Horseshoe Island, a small rocky island in Bourgeois Fjord, Marguerite Bay in the south-west Antarctic Peninsula, we describe the lichen species Candelariella ruzgarii as new to science. Sequences of the nrITS, mtSSU and RPB1 gene regions of the new species were amplified and revealed that the phylogenetic position of the new species is in the C. aurella group, which is characterised by 8-spored asci and ± granular thalli. Candelariella ruzgarii is phylogenetically most closely related to C. aurella s. lat. but differs mainly in ecology as the new species grows on soil or on terricolous lichens, whereas the latter species grows on calcareous rocks, rarely on wood. Morphologically, C. ruzgarii is very similar to C. aggregata, a Northern Hemisphere species that grows on mosses and plant debris. Apart from the different phylogenetical position, C. ruzgarii has a thicker and sometimes slightly crenulated thalline margin and somewhat shorter ascospores than C. aggregata. We also report C. plumbea for the first time from Antarctica, a species with a thick and grey thallus that was previously known from Europe and Asia.

Opis:
Any newly created area includes human-created habitats such as the mineral material of post-coal mining spoil heaps undergoing natural colonization and ecosystem development during the succession processes of vegetation colonization. The study of the factors that influence the succession dynamics, and the mechanisms behind this, have a long history (including the species-area relationship or Arrhenius equation). Nevertheless, the list of scientific questions is increasing. One of the significant issues in the study of these processes is the relationship between factors influencing the Biodiversity–Ecosystem Functioning (BEF) relationships. The main prerequisite is the relationships between the plant species' assemblage mechanisms including diversity and the variety of assembly rules concerning the environmental abiotic habitat processes and these properties are not straightforward. At the large scale, parameters such as age and area of the colonized sites are considered to be important. These relationships are more complicated in newly established post-mineral excavation habitats where novel ecosystems are developing. Regardless of the degree of disturbances, vegetation re-establishes in such environments, as a result of spontaneous succession, by the colonization and establishment of the best-adapted organisms. In the habitats of post-coal mining spoil heaps with pure oligotrophic mineral conditions, the non-analogous, newly formed composition of flora, fauna, and saprophytes has been stated in many previous field studies. This study aimed to explore the biodiversity versus area size relationships, in particular, it investigated the species composition and diversity found in the development of the spontaneous vegetation formed during primary succession on mineral substrate habitats of postcoal mining spoil heaps of different area sizes. We tested the hypothesis: species diversity of the vegetation patches on coal mine spoil heaps becomes more diverse on larger sites over time. These results indicate that the area size of the spoil heap significantly affects the diversity of the vegetation. Regardless of which of the characteristics of the vegetation type (dominant species) is compared, the vegetation on the heaps differs depending on its area size.

Opis:
A widely publicized IPBES report from 2019 warns that close to one million species currently on Earth will soon be extinct. In addition to debates in the media and among professionals about the factual value of that number, a larger problem remains—we do not know how many species are on Earth. According to extensive studies and statistical modelling, there are at least six million species in existence that have not yet been described. The term “described species” means that the animal or plant has received a unique scientific name that confirms its identity and relation to other organisms. A question thus remains about how we value species that are not yet named, known, or discovered. The most common practice is to value only creatures that are directly related to human existence, yet there is growing concern that we should value animals for the sake of their existence, for their intrinsic value. In this respect, the anthropocentric concepts of “pest” and “invasive species” need to be re-considered.
Авторы широко комментированного отчета IPBES от 2019 года предупреждают, что около миллиона видов, живущих в настоящее время на земле, скоро вымрут. Однако в дискуссиях, ведущихся как в СМИ, так и среди профессионалов поднимается другая проблема – мы не знаем, сколько видов обитает на земле. Согласно обширным исследованиям и статистическому моделированию существует не менее шести миллионов видов, которые еще не описаны или не названы. Термин «описанный вид» означает, что животное или растение получили уникальное научное название, подтверждающее его идентичность и родство с другими живущими существами. Таким образом, остается вопрос о том, как мы оцениваем виды, которые еще не названы, не известны или не обнаружены. Наиболее распространенной практикой является оценка только тех существ, которые непосредственно связаны с человеческим существованием, однако встречаются размышления о том, что мы должны ценить животных также ради их существования, за их внутреннюю ценность. В связи с этим необходимо пересмотреть такие антропоцентрические понятия как «вредитель» и «инвазивный вид».
Autorzy szeroko nagłośnionego raportu IPBES z 2019 roku ostrzegają, że liczba gatunków, które wyginęły na Ziemi, wkrótce przekroczy milion. W debatach prowadzonych zarówno w mediach, jak i wśród profesjonalistów porusza się jednak jeszcze inny problem – nie wiemy mianowicie, ile w ogóle gatunków żyje na Ziemi. Na podstawie wyników szeroko zakrojonych badań i modelowania statystycznego szacuje się, że istnieje jeszcze co najmniej sześć milionów gatunków, które nie zostały opisane ani nazwane. Termin „opisany gatunek” oznacza, że zwierzę lub roślina otrzymały niepowtarzalną nazwę naukową, która potwierdza jego/jej tożsamość i pokrewieństwo z innymi organizmami. Powstaje zatem pytanie, czy, a jeśli tak, to jak cenimy gatunki, które nie zostały jeszcze odkryte ani tym bardziej nazwane. Najczęstszą praktyką jest docenianie tylko tych stworzeń, które są bezpośrednio związane z ludzką egzystencją, coraz częściej jednak pojawiają się refleksje, że powinniśmy cenić zwierzęta ze względu na ich istnienie, ich wartość samą w sobie, a nie tylko ze względu na ich wartość dla człowieka. W związku z tym należy ponownie rozważyć antropocentryczne koncepcje takich pojęć jak „szkodnik” czy „gatunek inwazyjny”.

Opis:
The aims of this study are to model past (LIG, LGM and Mid-Holocene), present and future (2050 and 2070) distributions of the Quercus vulcanica Boiss. & Heldr. ex Kotschy by using Maximum Entropy, and to predict suitable areas for the conservation of the species for future planning. MaxEnt distribution modeling was used to model distributions. Results for past bioclimatic conditions show that the distribution area of the species expanded and then contracted (LIG to LGM and LGM to HOL). The modelling shows that the distribution range of the species will be narrower in the future. The species will be facing extinction towards 2070. Therefore, the conservation status of the species should be evaluated according to the present findings. Although the largest population of the Q. vulcanica is found in Isparta and Afyonkarahisar Provinces located in Southwestern Turkey, this area will not be suitable for the growth and survival of the species in the future. For this reason, a new nature reserve area should be established in a more suitable climate.

Opis:
The purpose of the research was to assess the species composition and biodiversity indices for xylophagous beetles collected by window traps in the parts of Gomilshanski lisy National Nature Park with different management regimes and anthropogenic load. Four window traps were placed in each of the five groups of sample plots: clear felling, selective felling, stationary recreation, regulated recreation and protected zone. The data were analysed using the statistical software package PAST, particularly, the Menhinick index (DMn) and dominance index (D) were evaluated and classical clustering (unweighted pair-group average [UPGMA]) was performed. A total of 42 species of xylophages (9903 individuals) were collected from Curculionidae (Scolytinae and Cossoninae), Cerambycidae, Histeridae, Bostrichidae, Buprestidae and Lymexilidae. The highest species richness was in the plots of clear and selective felling (25 and 22 species, respectively) and the lowest was in the protected zone (16 species), regulated recreation (19 species) and stationary recreation (22 species). The Menhinick index (DMn) was the lowest in the protected zone (0.27), increased in the zone of regulated recreation (0.43) and stationary recreation (0.45) and was maximal in the plots of selective and clear felling (0.69 and 0.77, respectively). The number of individuals was maximal in the protected zone and minimal at the plots of selective and clear felling. All sites were dominated by Xyleborinus saxesenii (Ratzeburg, 1837) (66–85% individuals) and Anisandrus dispar (Fabricius, 1792) (8.5–20.7% individuals). Minimal dominance (0.49) was found in the plot of clear felling. Cluster analysis showed similarity of the xylophage complex in the plots of clear and selective felling, as well as in the zone of stationary and regulated recreation, which differed from the protected zone.

Opis:
University campuses, as important elements of urban greenery, are related with a positive impact on student health and well-being. They provide unique possibilities for estimating biodiversity change. This study focused on the biodiversity in the Campus. The study aimed at: assessing the plant biodiversity occurring in the park; assessing the representation of native species and determining the frequency at which invasive species occur; as well as recommending an adaptation of the park management. The Park was sub-divided into biotopes and a phytocoenological relevé was recorded. Park projects create biodiversity islands that may contribute to improve urban space. A species composition that is close to natural vegetation creates a space for native species, which thus better adapt to living in urban conditions. Localities created by humans, which imitate natural ecosystems, increase the biodiversity and are valuable natural islands in cities. The semi-natural phytocoenoses however, do not resist the occurrence of invasive plant species. Regarding the small size of the studied park, manual elimination or cutting of invasive plant species is sufficient.

Opis:
Laricifomes officinalis is a wood-decay fungus that is closely associated with old individuals of Larix decidua. In the twentieth century, L. officinalis was over-harvested because of its medicinal properties; consequently, it has become very rare or almost extinct in the Alps. In this study, we investigated the population of L. officinalis in the Alpe Veglia–Alpe Devero Natural Park (Val d’Ossola, Italy) to assess a preliminary conservation strategy. Population consistency was estimated using field mapping, and spatial analysis was performed on host trees based on topographical and environmental variables. Mycelia were isolated from harvested basidiomata, and strain identity confirmed by molecular analysis of the ITS region. All isolated strains were tested for growth in Petri dishes containing different standard media to determine which strains had the highest growth rates; the fastest growing strains may be selected for future studies and applications. Compared to the control strains from Val Malenco and Parco Nazionale del Gran Paradiso, all strains from Alpe Veglia–Alpe Devero Natural Park had lower growth rates. There was no significant difference between the growth rates of strains from Alpe Veglia and those from Alpe Devero. The results suggest that the population consistency of L. officinalis in the Alpe Veglia–Alpe Devero Natural Park is related to two main factors: habitat preservation and harvesting prohibition. These results confirm the need to protect L. officinalis both inside and outside natural reserves, despite the apparent increase in local populations.

Opis:
Amphibia is a class of vertebrate. Amphibians are ectothermic, or cold-blooded, and they have smooth skin that must stay moist to prevent desiccation. They play an important role in nature both, as predator and prey. Nagaland is one of the north eastern hilly states and it is very rich in biodiversity. Due to the geographical position, Nagaland has a huge number of amphibian fauna. Purpose of the present study is to get information of sociocultural relation of frog and Naga people and to study the diversity. Study was conducted through the market survey and interview. Interview was conducted among the people of different age groups which are belonging to different tribes. Frog species were collected from the markets and Morphometric measurements were taken by using a vernier caliper. Frog samples were kept as museum specimen. From the investigation, all together 11 species from 4 families were recorded from the market and identified with the help of relevant literature. Cooking procedure of frog meat among the people of Nagaland varies from tribe to tribe and people to people. Most common method of consumption is boiling with bamboo shoot. Naga people have traditional believe that frogs have medicinal purposes. Different body parts of the frog are consumed by different way to cure the various diseases. Frog eating is a traditional way and continued practice among the Naga society from the time of civilization to obtain the protein, and frogs are easily available in the markets in both, as fresh and dried. Frogs are being exploited from nature from year after year without having proper maintenance and conservation. The results of the study revealed that there is no reduction in frog population, though they are being collected in a huge number. It is necessary to culture the frog species and to establish socio-ecological system through a sustainable management and conservation of biodiversity.

Opis:
In the mountains of the north-central Sicily (Italy), a small and isolated population of Sicilian fir (Abies nebrodensis) has survived to the present day. It is the most unique species of the Sicilian flora, not only because of its taxonomic position, but mostly because of its endemic and relict status and the serious risk of extinction. The single natural population of this extremely rare species is currently represented by only 30 mature individuals scattered over a small area in the Madonie Mountains. This species has experienced intensive population decline since the end of the 17th century, and its situation became extremely critical in the first decades of the 19th century due to deforestation and overgrazing. Consequently, Sicilian fir was considered to be extinct about three decades before being rediscovered on the Madonie Mts. in 1937. Sicilian fir is recognized as one of the most endangered coniferous species in the world. It is classified as critically endangered by IUCN, and also included in the list of 50 most endangered plant species in the Mediterranean region. Currently, the limited population size, a small proportion of reproductive individuals, habitat loss, ongoing and projected climate change, and hybridization with other species pose serious threats to survival of this species. Therefore, it is extremely important to maintain actions focusing on in situ and ex situ conservation in order to preserve and protect the existing resources of Sicilian fir, which represents the natural heritage unique to the Mediterranean.

Opis:
The development of reconstructed woody vegetation on coal mine dumps during the trajectory of reclamation was explicitly investigated by means of a rehabilitation technique. However, limited information is available about the composition of herbaceous species during the ecosystem re-development on mine dumps. The present study attempted to assess the composition of herbaceous vegetation beneath plantation stands of four native woody species on the coal mine spoil in a dry tropical environment. After a thorough survey of the study site, a total of 44 species of herbaceous plants belonging to 14 families were recorded. Among the recorded plant families, the Poaceae contributed the highest number of species (18) across all ages of all plantation stands. The biodiversity parameter such as species richness exhibited an increasing trend with age under plantation stand of T. grandis only, while the rest of the plantations showed a decreasing trend. In terms of the similarity index, the plantation stands of A. procera and T. grandis were closer to each other while A. lebbeck and D. strictus were farthest apart. However, the highest IVI was recorded in the seedling of A. lebbeck under the planted stand of A. lebbeck while lowest of Rungia repens (2.85) under A. procera stands at 17th-year of age. In conclusion, the plantation age, dominant tree species, and species specificity have a significant impact on the development of herbaceous vegetation beneath the plantation stand of four native woody species.

Opis:
This study addresses the assessment of the legal model of protection against invasive plant species. Invasive alien species are one of the main risks to biodiversity and related ecosystem services. The threat to biodiversity and related ecosystem services posed by invasive alien species takes various forms. Moreover, invasive alien species have a significant impact on native species and on the structure and function of the ecosystem. There is a very low awareness of this phenomenon in Poland and worldwide. Therefore, legal instruments and appropriate knowledge are the basic elements of building a strategy for dealing with invasive alien species.
Niniejsze opracowanie dotyczy oceny modelu prawnej ochrony przed inwazyjnymi gatunkami roślin. Inwazyjne gatunki obce stanowią jedno z głównych zagrożeń dla różnorodności biologicznej i powiązanych usług ekosystemowych. Zagrożenie dla bioróżnorodności i powiązanych usług ekosystemowych, jakie stwarzają inwazyjne gatunki obce, przybiera różne formy. Ponadto inwazyjne gatunki obce wywierają znaczny wpływ na gatunki rodzime oraz strukturę i funkcję ekosystemów. W Polsce i na świecie jest bardzo niska świadomość o tym zjawisku. Stąd też instrumenty prawne i odpowiednia wiedza są podstawowymi elementami budowania strategii postępowania z inwazyjnymi gatunkami obcymi.

Opis:
Salt licks play an important role in the health of wildlife by supplying the essential minerals required especially for herbivores. This study assessed nine mineral salt lick sites, fauna utilization and tree species diversity in response to threats encountered at the site. Systematic random sampling, quadrat sampling and transect survey were used as the methodological indices to carry out the research. The dominant tree species is Anogeissus leiocarpus while recessive species was Vitellaria paradoxa. Fauna distribution and abundance within and across mineral salt lick sites were observed. Kobs (Kobus kob) were highest while Tantalus monkey (Chlorocebus tantalus) and Warthog (Phacochoerus aethiopicus) had least encounter rate. Park management should implement conservation education, stringent policies against wildlife offences and constant surveillance to conserve biodiversity in protected ecological site. The overall benefits derived from salt licks for wildlife health, majorly through herbivores are crucial in maintaining a healthy wildlife community for their reproduction and survival.
