Abstract:   (675 Views)
Anthropic land covers (ALCs) can also harbor spiders in human-modified landscapes (HMLs), aside from protected landscapes. This study determined the diversity of spiders in seven different ALCs within the University of the Philippines Mindanao campus to identify ALCs with the highest priority for spider conservation. Direct sampling methods were employed to collect specimens within 2000 m2 belt transects. A total of 364 spider individuals belonging to 69 morphospecies from 40 genera and 13 families were documented. Highest species richness was observed from the family Araneidae. Nephila pilipes (Araneidae) and Heteropoda venatoria (Sparassidae) were found across sampling sites. Among the ALCs, site 5OGSF (old-growth and secondary forest) had the highest species richness [q0 (26)] while site 7AF (agroforest) had the highest species diversity [q1 (17.16); q2 (13.83)]. Site 3CTP (cacao tree plantation) was consistently the least species-rich [q0 (10)] and least diverse [q1 (6.92); q2 (5.54)]. The different vegetation density and structural complexity of ALCs on the campus support spider communities, in which the highest species richness and diversity were observed in the secondary forest and agroforest, respectively. This paper highlights that spider communities have varying levels of diversity in different small-scale ALCs.
