“…While a rich diversity of spiders was found in nests across both gradients, we detected increased abundance of spider hunting wasps in rural sites, indicating increased food availability at rural sites. For example, sheet web weavers, such as linyphiid spiders, benefit from vegetation cover and low landscape fragmentation, resulting in higher abundances and species richness (Argañaraz & Gleiser, 2020). However, in our study, the high occurrence of linyphiid spider Linyphia triangularis in urban settings was probably due to their potential increased occurrences in parks and gardens near our sampling sites.…”

Urbanization is affecting arthropod communities worldwide, for example by changing the availability of food resources. However, the strength and direction of a community's response is species‐specific and depends on species' trophic level. Here, we investigated interacting species at different trophic levels in nests of cavity‐nesting bees and wasps along two urbanization gradients in four German cities using trap nests. We analysed bee and wasp diversity and their trophic interaction partners by metabarcoding the DNA of bee pollen and preyed arthropods found in wasp nests. We found that the pollen richness increased with increasing distance from city centres and at sites characterized by a high percentage of impervious and developed surface, while the richness of pollinators was unaffected by urbanization. In contrast, species richness of wasps, but not their arthropod prey, was highest at sites with low levels of urbanization. However, the community structure of wasp prey changed with urbanization at both local and regional scales. Throughout the study area, the community of wasps consisted of specialists, while bee species were generalists. Our results suggest that Hymenoptera and their food resources are negatively affected by increasing urbanization. However, to understand distribution patterns of both, wasps and bees in urban settings other factors besides food availability should be considered.

“…Spiders (Subphylum Arthropoda, Class Arachnida) are organisms that can be found in almost all types of ecological environments (Foelix, 2011). Spiders adapt to new microhabitats created by humans such as residential areas (Argañaraz and Gleiser, 2021).…”

Ecosystem changes due to human activities can affect habitats for several organisms, such as spiders. Spiders have an important role as a predator for mosquitoes, flies, and ants. One of the spider families is Salticidae. Most species from Salticidae are cosmopolitan and often found in an area with dense human activity, such as residential areas. Study about spider species in residential areas is important to determine the effect of urbanization on spider diversity. This research aimed to study about spider species from Salticidae family found in the Serang Residential Area. The individual spider was caught directly by hand, then documented with macro photography techniques. Data analysis was carried out by describing the morphological characters. The results showed 5 species, namely Hasarius adansoni, Menemerus nigli, Menemerus fulvulus, Plexippus paykulli and Plexippus petersi. Documentation using good photography helps in making identification easier. This research is expected to be used as a reference for further research about a spider in a residential area.
