Opis:
Recent survey on the weed flora of tea ecosystem of Ri-Bhoi district of Meghalaya has recorded 66 weed species belonging to 51 genera under 31 families. This was the first attempt to explore the weed flora of tea plantations of Meghalaya. Two species namely Bidens pilosa L. and Clerodendrum paniculatum L. are reported for the first time from the tea plantation of North East India. Regarding family-wise contribution Poaceae contributing highest number (14) of species followed by Asteraceae (10), Cyperaceae (5), Lamiaceae (4), Amaranthaceae (2), Caesalpiniaceae (2), Malvaceae (2), Polygonaceae (2), Solanaceae (2) & Schizaeaceae (2). Other families are having single representative. 23 weed species have been identified as ethno-biologically important. Local Khasi tribal peoples use these weeds as folk medicine against various diseases and other purposes.

Opis:
The Meghalaya Plateau, located in NE India, forms hilly horst block elevated to about 2000 m a.s.l. In the subtropical monsoonal climate, with strong mean annual rainfall gradient from 11,000 mm in Cherrapunji to 2,200 mm in Shillong and 1,600 mm in Gauhati were developed several cultivation systems. The shifting cultivation is the oldest and predominant system at lower elevations (such near Gauhati). It induces soil loss of about 40 t ha⁻¹ yr⁻¹ under cereals and perennial cropping on slopes up to 25-40°. As long as this system has long a cycle which permits forest regrowth on the abandoned fields, the effect of agricultural activity is not visible in the soil profiles. Intensive human activity (near Shillong), resulted in development of the sedentary agriculture, where soil erosion rates of about 55 t ha⁻¹ y⁻¹ are observed under potato cultivation. Radiocarbon dates of colluvial deposits in this area indicate intensification of agricultural human activity from at least 200-300 years. Closer to the southern margin of the plateau (near Cherrapunji), high monsoonal rainfall combined with cultivation in the past caused transformation of forest to grassland. The erosion below 2 t ha⁻¹ yr⁻¹ indicates that compact pavement of soil and root grass system has exerted a greater control over the sediment transfer than the energy impact of the rainfall and overland flow. Only wet rice cultivation in populated valleys and creation of terraces does not threat the environment. Various forms of agriculture and accelerated soil erosion lead to the gradual retreat of cultivated fields from high to low rainfall areas on the Meghalaya Plateau.

Opis:
The present study is on the spider fauna of Nongkhylem Wildlife Sanctuary (NWS), Sohra (Cherrapunji) [included within East Khasi Hill District], Umsning (Ri Bhoi District) and their surrounding tea estates (Anderson Tea Estate, Byrnihat Tea Estate and Meg Tea Estate) of Meghalaya, India. A total of 55 species belonging to 36 genera and 13 families are sampled. Newly recorded taxa include four genera and 11 species of Araneidae, six genera of Araneidae, each represented by single species. The species recorded under Tylorida Simon and Tetragnatha Latreille of Tetragnathidae and Camaricus Thorell and Thomisus Walckenaer of Thomisidae are found to be new from the state. Also, three oxyopids and one miagrammopid are new. So far, Linyphiidae, Pisauridae, Sparassidae and Theridiidae were unknown from the state. Out of 55 species, 13 are endemic to India and thus exhibiting a high endemicity (23.6%). A family key of the State Fauna is provided along with relevant images of the newly recorded species.
