We have observed seven species of predator beetles of the genus Bembidion in the agricultural landscape of the Leningrad Region (Northwestern Russia) between the years 2008 and 2018. These species reach their highest abundance in sun-exposed areas, especially mesophilic B. quadrimaculatum Linnaeus, 1761, B. properans (Stephens, 1828), B. lampros (Herbst, 1784), and B. femoratum Sturm, 1825. A few mesohygrophilic B. guttula (Fabricius, 1792) and B. gilvipes (Sturm, 1825) live primarily in areas of dense vegetation. Finally, the hygrophilic B. bruxellense (Wesmael, 1835) was only observed on the most humid soils. Assemblages of Bembidion ground beetles were separated in the fields, field boundaries, and adjacent habitats.

Species Tolerance

Worldwide human-induced habitat fragmentation intensifies the emergence of forest edges. In addition to these edges, there are edges evolved by natural processes. Edge-maintaining processes (natural vs. anthropogenic) fundamentally determine edge responses, and thus edge functions. Species with various traits show fundamentally different edge response, therefore the trait-based approach is essential in edge studies. We evaluated the edge effect on the body size of ground beetles in forest edges with various maintaining processes. Our results, based on 30 published papers and 221 species, showed that natural forest edges were impenetrable for small species, preventing their dispersal into the forest interiors, while both the medium and the large species penetrated across these edges and dispersed into the forest interiors. Anthropogenic edges maintained by continued human disturbance (agriculture, forestry, urbanisation) were permeable for ground beetles of all size, allowing them to invade the forest interiors. Overwintering type (overwintering as adults or as larvae) was associated with body size, since almost two-thirds of the small species, while slightly more than a third of both the medium and the large species were adult overwintering. Based on this, size-dependent permeability of natural edges may be related to overwintering type, which basically determines species tolerance to human disturbance.

The Matrix

Small mammals were trapped in four rain forest fragments (3, 8, 20 and 97 ha), in an agricultural landscape, and in comparable continuous tropical rain forest in north Queensland, Australia over 2 y. The most frequently captured species were four murid rodents. Melomys cervinipes were captured in similar numbers in both continuous and fragmented forest. This species achieves greatest abundance at forest edges and this study suggests that edges of fragments and edges of continuous forest will support similar densities. Abundance of Uromys caudimaculatus was positively correlated with size of fragment and peaked in continuous forest. This species had a home range larger than the smaller fragments and was thus disadvantaged but its ability to utilize the agricultural matrix between fragments mitigated the effect. Rattus leucopus and R. fuscipes were most abundant in fragments and continuous forest respectively but both species occurred in similar abundance in the 97-ha fragment. This suggests their population size is related to habitat rather than competitive exclusion as previously postulated. Ordination of the populations of the nine most commonly captured mammals, separated the fragment and continuous sites but placed the largest fragment closest to the continuous sites. The contrasting response of the two Rattus spp. was the primary influence on the ordination. Second in importance was Trichosurus vulpecula, a folivorous possum, which was absent from the continuous sites. The fragments may have had more nutrient-rich, pioneer tree foliage than continuous forest. Isoodon macrourus, Perameles nasuta, Antechinus godmani and Uromys hadrourus also showed positive or negative response to fragmentation. Species utilizing the matrix between forest fragments and species adapted to forest edge are advantaged by the fragmentation process whereas forest specialists tend to extinction in fragments, particularly where the home range of the animal is not many times smaller than the fragment.

<p>In agricultural landscape in northern slope of Mount Slamet, diversity of wild bee species as pollinator depend on forested habitats. This study aimed to assess the effects of distance from the forest edge on the diversity of wild bees on strawberry and tomato crops. This study was conducted from July 2014 to October 2014. The experimental fields contained tomato and strawberry with a total area of 4 ha (2 ha each) and divided into five plots based on distance from the forest edge (0, 50, 100, 150, and 200 m). Wild bee was catched with  kite netting  in 7.00 -9.00 in ten consecutive days. Wild bee diversity differed according to distance from the forest edge, the highest value was at 0 m for strawberry plots (H’ = 2.008, E = 0.72 and Chao1= 16) and for tomato plots, the highest diversity was at 50 m from the forest edge (H’ = 2.298, E = 0.95 and Chao1= 11) and the lowest was at 200 m in both plots. Wild bee species richness and abundance decreased with distance, resulting in the minimum diversity and abundance of wild bee at 200 m from forest edge in both crops.</p><p> </p><p><strong>How to Cite</strong></p><p>Widhiono, I., &amp; Sudiana, E.

SummaryHuman modified landscapes make up a growing proportion of the tropics, but are relatively little studied. The spatial distribution of remnant vegetation can structure and shape local biodiversity, affecting the provisioning of ecosystem services and regulation of pest problems. We compared species composition, abundance and functional diversity of birds between forest and homegardens close to (0–100 m) and further away from (1,500–2,000 m) moist evergreen Afromontane forests in south-western Ethiopia. We thoroughly inventoried birds with point counts and mist netting in two forest sites and three garden sites of each type. Gardens differed in general species composition from forests, with fewer forest specialist species (7% versus 29% of recorded species), but instead supported many other species that were rarely encountered in the forests. Overall gardens had higher numbers of species than forests. Homegardens close to the forest and further from the forest were similar to each other in terms of species richness and overall species composition. Both garden types had a similar composition in terms of the relative proportion of species with different habitat preferences as well as the composition of species from different feeding guilds. The lack of forest specialists in even the most structurally complex part of the agricultural landscape close to forest edges suggests that the last larger forest remnants are critical for conservation of forest specialists. Nonetheless, homegardens maintain rich bird diversity that also should be considered in a biodiversity conservation context. Further research is needed to establish to what extent the richness and composition of the agro-ecological bird fauna is regulated by the existence of forest patches in the region. Our results could not resolve this question since gardens two kilometers from the forest edge were similar in composition to gardens close to the forest edges.
