We report a checklist of spiders based on a survey made from August 2013 to July 2014 in Gujarat University Campus, an urban area located in the middle of Ahmadabad City, Gujarat State. A total of 77 species of spiders belonging to 53 genera and 20 families of spiders were recorded from the study area represented by 31.74% of the total 63 families reported from India. Salticidae was found to be the most dominant family with 18 species from 14 genera. Guild structure analysis revealed six feeding guilds, namely stalkers, orb-web builders, space-web builders, ambushers, foliage hunters and ground runners. Stalkers and orb-web builders were the most dominant feeding guilds representing 28.58% and 20.78% respectively among all studied guilds. Species Eilica tikaderi (Platnick, 1976) is reported for the first time from Gujarat with additional description and detailed genitalic illustrations.

Studies relating to spiders in Gujarat have been sporadic and most of the spider documentation have been done from agriculture fields, wetlands and  few from protected areas.  One such undocumented area was Jambughoda Wildlife Sanctuary, Panchmahal District, Gujarat.  Therefore, a study to document the spider diversity was carried out in Jambughoda Wildlife Sanctuary from July 2012 to October 2015. A combination of four sampling methods namely, belt transect along with hand-pick method, pitfall sampling, vegetation beating and leaf litter extraction were used for collection of spiders from different strata. During the study, a total of 138 species belonging to 90 genera and 29 families were recorded from the study area. Of which, 21 species and 17 genera were recorded for the first time from Gujarat State. The theridiid genus Cephalobares O. Pickard-Cambridge, 1870 was recorded for the first time from India. The families Araneidae, Salticidae, Theridiidae and Oxyopidae were found to be dominant in the area. We recognized seven feeding guilds namely ambushers, foliage runners, ground runners, orb weavers, sheet web-builders, space web-builders and stalkers.  Amongst these, orb-weavers, stalkers and ground runners were dominant. This documentation, however, forms the baseline information for spiders of Jambughoda WLS, suggesting the great diversity of the spider fauna in this protected area, which can be further explored.

Preliminary Study

Kavvayi river basin is a typical lateritic biotope situated in the Northern part of Kerala, which holds various ecological units such as lateritic vegetation, agro-ecosystems, seasonal pools, Grass lands, Kanams, Sacred groves, Mangrove marsh and riparian vegetation. Many of these microhabitats are unique in character and poorly documented. A preliminary study was conducted to document the diversity of spider fauna inhabiting in the different ecosystems of Kavvayi river basins. India is having 1,686 species of spiders belonging to 60 families and 438 genera, which constitutes 3.6% of world’s spider population. The present study resulted in the documentation of 112 species of spiders belonging to 81 genera and 21 families. Araneidae was the most dominant family which constitutes 21.5% of the total spider species collected. The second dominant family was Salticidae which constitutes 19.5% of total spider population. Guild structure analysis of the collected spiders revealed seven feeding guilds, namely stalkers, orb web builders, ambushers, foliage runners, space web builders, ground runners and wandering sheet weavers. The spider fauna of this ecosystem is qualitatively rich due to varied microhabitats, which supports high floral and faunal diversity. The present study suggests a detailed investigation at ecosystem level to understand the role of spiders in ecosystem function.

The Impact

AbstractPlant invasions alter bird community composition worldwide, but the underlying mechanisms still require exploration. The investigation of feeding guild structure of bird communities can be informative in respect to the potential impact of invasion features on the availability of food for birds. For this purpose, we focused on determining the influence of the invasive Sosnowsky’s Hogweed Heracleum sosnowskyi on the abundance of birds from various feeding guilds. In spring and summer 2019, birds were counted three times on 52 pairs of sites (control + Heracleum) in southern Poland, at various stages of Sosnowsky’s Hogweed development (i.e. sprouting, full growth and flowering, all corresponding to respective bird counts). We have shown that the presence of invader negatively affected the abundance of birds from all feeding guilds. However, a closer examination of the invaded sites uncovered that responses of particular guilds differed in respect to development stages expressed by a set of characteristics of the invader. Ground and herb insectivores were more common on plots with a higher number of the invader, while the abundance of bush and tree insectivores was negatively correlated with hogweeds’ height. Granivores were not affected by the invader’s features, while the abundance of omnivores was negatively related to the number of flowering hogweeds. Besides showing the general negative impact of the invader on different feeding guilds, our research has shown that certain aspects of Sosnowsky’s Hogweed invasion may support or depress occurrence of different birds on invaded plots. Knowledge of these aspects may facilitate our capacity for coping with challenges the invasive plants put in front of bird conservationists.
