“…Finally, natural protected areas provide an important pollination ecosystem service to crops because they provide nesting sites and floral resources for squash pollinators. Riparian habitats and forest reserves can maintain native and feral pollinators of crops (Brito et al 2017), and a good example was shown for the provisioning of floral resources and nesting sites of Peponapis crassidentata in the study area (Delgado-Carrillo et al 2017). Currently, only 4% of this study area is riparian habitat; thus it is crucial to protect this environment for providing resources for bees and other pollinator species (S anchez-Azofeifa et al 2009).…”

It has been proposed that species‐rich insect communities and species turnover across landscapes enhance the pollination efficiency of crops through complementarity, where both the dominant and less abundant species contribute to reaching a yield threshold from pollination. Alternatively, fluctuations in the most abundant pollinator species, rather than changes in species richness, may drive temporal variation in pollination services. In this study, we used Cucurbita moschata as a model to investigate temporal variation in pollinator communities in a Mexican tropical dry forest region. We sampled floral visitors in the coastal region of Jalisco during the wet and dry seasons and determined the pollination efficiency of all floral visitors. Our results showed that there was temporal variation in the pollinator community and in the pollination efficiency of the main pollinators of Cucurbita moschata crops. In the wet season, native bees of the genus Peponapis were the most frequent and effective pollinators of C. moschata, whereas in the dry season, Peponapis bees were scarce and Apis mellifera became the most frequent floral visitor. Apis mellifera transfers smaller pollen loads than Peponapis, but it provides an effective pollination service in conjunction with other native bees during the dry season. There was also an interaction between flower gender and pollinator species, where A. mellifera had higher visitation rate to female C. moschata flowers, and Peponapis bees to staminate flowers. Mean visitation rate by Peponapis female bees was 17 times higher than visitation rate by male bees. This is the first report of a vis‐à‐vis relationship of pollinator gender with respect to plant gender in which plants of the genus Cucurbita that produce unisexual staminate and pistillate flowers are differentially visited by Peponapis male and female bees, where females are the main pollinators. Understanding the temporal variation in pollinator communities and the contribution of the different species of pollinators to the reproductive success of different crop species and varieties can be crucial to maintaining pollination services under the current global pollination crisis.

“…The functional diversity of bird communities in oil palm was greatly reduced, in spite of evidence that birds protect oil palms against herbivorous insects (Koh, 2008). Other groups affected in the same way include anurans (Corrêa et al, 2015), aquatic Hemiptera (Cunha and Juen, 2017), bees (Brito et al, 2017), and aquatic insects (Juen et al, 2016).…”

In order to evaluate the impact of oil palm cultivation on dung beetles in the eastern Brazilian Amazon, comparisons were made of communities in oil palm plantations and native forest. Pitfall traps baited with human feces were buried to soil level in plantations and surrounding forests. Fifty traps were used in each type of vegetation, placed at 50 m intervals along five transects. Dung beetle communities in oil palm plantations have lower species richness (18 spp.) than in surrounding tropical rainforest (48 spp.), as well as altered species composition. Total abundance of individuals was not significantly different between the two habitats, but species composition was greatly different. Species evenness was greater in the forest. Forest corridors for the preservation of dung beetle species may need to be much wider than current designs. The erosion of biodiversity in dung beetles due to oil palm monoculture parallels what has been seen in other animal taxa in tropical tree plantations.

“…Agricultural practices lead to losses of natural resources and biodiversity (Godfray & Garnett, ). One mechanism to minimize the impact of clearing for agriculture and other production activities on biodiversity is to maintain riparian forest strips (insects: Barlow et al, , Brito et al, , Gray, Lewis, Chung, & Fayle, , Gray, Slade, Mann, & Lewis, ; macroinvertebrates: McClain, ; fish: Giam et al, ; birds: Machtans, Villard, & Hannon, , Mitchell et al, , Whitaker & Montevecchi, ; bats: Lloyd, Law, & Goldingay, , Mullin, ; small mammals: Al‐Khudhairy Gutierrez, ; Chapman & Ribic, ; Cockle & Richardson, ; Darveau, Labbe, Beauchesne, Belanger, & Huot, ; large and medium‐sized mammals: Paolino et al, , Phoebus, Segelbacher, & Stenhouse, , Zimbres, Peres, & Machado, ). These strips may become prominent features in agricultural landscapes and may assume disproportionate roles in protecting biodiversity outside protected areas (Arriaga‐Flores, Castro‐Arellano, Moreno‐Valdez, & Correa‐Sandoval, ; Mendenhall, Karp, Meyer, Hadly, & Daily, ; Naiman, Decamps, & Pollock, ).…”

Agricultural practices lead to losses of natural resources and biodiversity. Maintaining forests alongside streams (riparian forest strips) has been used as a mechanism to minimize the impact of clearing for agriculture on biodiversity. To test the contribution of riparian forest strips to conserve biodiversity in production landscapes, we selected bats as a biodiversity model system and examined two dimensions of diversity: taxonomic and functional. We compared bat diversity and composition in forest, with and without stream habitat, and in narrow forest riparian strips surrounded by areas cleared for agriculture. We tested the hypothesis that riparian forest strips provide potential conservation value by providing habitat and serving as movement corridors for forest bat species. Riparian forest strips maintained 75% of the bat species registered in forested habitats. We found assemblage in sites with riparian forest strips were dominated by a few species with high abundance and included several species with low abundance. Bat species assemblage was more similar between sites with streams than between those sites to forests without stream habitat. These results highlight the importance of stream habitat in predicting presence of bat species. We registered similar number of guilds between forest sites and riparian forest strips sites. Relative to matrix habitats, stream and edge habitats in riparian forest strips sites were functionally more diverse, supporting our hypothesis about the potential conservation value of riparian forest strips. Results from this study suggest that maintaining riparian forest strips within cleared areas for agricultural areas helps conserve the taxonomic and functional diversity of bats. Also, it provides basic data to evaluate the efficacy of maintaining these landscape features for mitigating impacts of agricultural development on biodiversity. However, we caution that riparian forest strips alone are not sufficient for biodiversity maintenance; their value depends on maintenance of larger forest areas in their vicinity.
