Opis:
Sustainable (and adaptive) management of natural resources is usually based on long term local experiences with nature. Local traditional communities often possess rich ecological knowledge connected to nature and traditional resource use and management. This knowledge can provide unexpected new information for researchers, and show new opportunities and ways for professionals in conserving rare and threatened species. We found significant new populations of the rare Ophrys lesbis in a private area next to the settlement of Çamlık, Muğla, and Orchis punctulata in the graveyard of Kadılar, Antalya with the help of local rural people. We firstly report the replanting of some orchid species (Orchis papilionacea, O. italica, and Barlia robertiana) in kitchen gardens of Çamlık and Bayır, in Muğla Province. The presence of significant orchid populations (e.g., the biggest ever found for Ophrys lesbis) in an area, where local owners have been actively harvesting salep from year to year for decades suggests that the moderate salep harvesting can be sustainable for long run. Based on our observations, Turkish salep harvesters can help botanists and conservationists find new locations of rare threatened orchid populations, and therefore indirectly help in conserve these populations.

Opis:
The Pannonian endemic species Vincetoxicum pannonicum was described from specimens collected in Hungary and occurs at only few locations. It is considered “vulnerable” according to the International Red List. The chromosome set was reported to be tetraploid, and the species was hypothesized to be an allotetraploid hybrid of the Balkan species V. fuscatum and the Adriatic species V. hirundinaria subsp. adriaticum. We investigated the origin of V. pannonicum using molecular phylogenetic methods by separately analyzing the multicopy nuclear ribosomal internal transcribed spacer (nrITS) and the plastid-encoded trnH-psbA DNA regions and by evaluating discrepancies between the produced gene trees. Paralogs in the nrITS region clustered in two main groups, one of which was closest to V. fuscatum, and the other included V. hirundinaria subsp. adriaticum. According to trnH-psbA sequences, V. pannonicum and V. hirundinaria subsp. adriaticum formed a single group. Our results show that V. pannonicum diversified because of hybrid speciation, in which V. fuscatum was the pollen donor. We discovered a similar placement of V. maeoticum, which suggests a further hybridization event between V. fuscatum and a species of the V. hirundinaria group. Our genome-size estimate indicates almost sixfold larger genome size in V. pannonicum compared to the maternal diploid parent, suggesting hexaploidy; however, V. pannonicum is tetraploid. This may suggest cytological diploidization in the allopolyploid V. pannonicum. We observed substantial genetic distance between V. hirundinaria subsp. adriaticum and all other subspecies of V. hirundinaria, and we therefore propose that V. adriaticum should be regarded as a separate species.

Opis:
This article addresses the study related to forecasting with an actual high-speed decision making under careful modelling of time series data. The study uses data-mining modelling for algorithmic optimization of transport goals. Our finding brings to the future adequate techniques for the fitting of a prediction model. This model is going to be used for analyses of the future transaction costs in the frontiers of the Czech Republic. Time series prediction methods for the performance of prediction models in the package of Statistics are Exponential, ARIMA and Neural Network approaches. The primary target for a predictive scenario in the data mining workspace is to provide modelling data faster and with more versatility than the other management techniques.

Opis:
The paper reports chromosome numbers for 13 taxa of Elatine L., including all 11 species occurring in Europe, namely E. alsinastrum, E. ambigua, E. brachysperma, E. brochonii, E. californica, E. campylosperma, E. gussonei, E. hexandra, E. hungarica, E. hydropiper, E. macropoda, E. orthosperma, E. triandra originating from 17, field-collected populations. For seven of them (E. ambigua, E. californica, E. campylosperma, E. brachysperma, E. brochonii, E. hungarica, E. orthosperma) the chromosome numbers are reported for the first time. With these records, chromosome numbers for the whole section Elatinella Seub. became available. Although 2n = 36 was reported to be the most common and the lowest chromosome number in the genus, our data show that out of thirteen species analyzed, six had 36 chromosomes but five species had 54 chromosomes, and the lowest number of chromosomes was 18. These data further corroborates that the basic chromosome number in Elatine is x = 9.

Opis:
It was proposed previously that passive dispersal by migratory aquatic birds explain the widespread distribution of many wetland organisms. Several experimental studies have shown that many widespread wetland plant species can be readily dispersed within the guts of Anatidae. However, it is unclear whether plants with a more restricted distribution are able to disperse via waterbirds. This paper addresses the dispersal ability and germination ecology of the little-known Hungarian milkvetch Astragalus contortuplicatus, which occurs on banks of continental rivers and has a limited and unpredictable distribution. To test whether limited capacity for endozoochory by waterfowl could explain the sporadic appearance of this species, we force-fed ten captive mallards (Anas platyrhynchos) with 100 milkvetch seeds each. Droppings were collected for up to 45 h after feeding. Intact and viable seeds were found in the droppings of each mallard, and altogether 24.7% of seeds fed were recovered intact. The proportion of retrieved seeds that germinated (27.0%) was significantly higher than that of untreated control seeds (0.5%), but significantly lower than that of mechanically scarified seeds (96.0%). Retrieved seeds that germinated developed into healthy mature plants. Given the average flight velocity of mallards, seeds of A. contortuplicatus may travel up to 1600 km inside the digestive tract of migrating individuals. Our results suggest that avian vectors may be more important for the dispersal of rare higher plants (especially those with a hard seed-coat) than hitherto considered. Moreover, they suggest that rarity does not necessarily indicate limited dispersal ability, and may instead be explained by specific habitat requirements.
