Ecological Entomology, Journal Year: 2020, Volume and Issue: 46(2), P. 143 - 159

Published: Nov. 26, 2020

About 3/4 of all wild bee species nest in the soil and spend much their life cycle underground. These insects require suitable environmental conditions for construction development survival offspring. However, there is little quantitative information on nesting habitat requirements preferences ground‐nesting bees. Moreover, are almost no data effects these bees' fitness. Here, to better understand factors that influence nest‐site selection bees, we synthesise literature nesting‐habitat associations important pollinators. We also review techniques can be used study Our reveals enormous variation among with such attributes as texture, compaction, moisture, temperature, ground surface features, proximity conspecifics or floral resources. more studies—particularly experimental ones—are needed segregate each factor choices location, since multiple often correlated. It unclear whether vary geographically seasonally within species, phylogenetically partly because lack many species. argue studies using established habitat‐selection methods essential properly identify Finally, research ecology (especially agroecosystems) determine how best support this diverse group bees vital ecosystem service they provide.

Abstract Many bee species are declining globally, but to detect trends and monitor assemblages, robust sampling methods required. Numerous used, a critical review of their relative effectiveness is lacking. Moreover, evidence suggests the depends on habitat, yet efficacy in urban areas has be evaluated. This study compared community documented using observational records, targeted netting, mobile gardens, pan traps (blue yellow), vane trap‐nests. The comparative surveys native bees honeybees were undertaken an urbanized region southwest Australian biodiversity hot spot. outcomes then synthesis based comprehensive literature studies where two or more conducted. Observational records far exceeded all other terms abundance recorded, unable distinguish finer taxonomic levels. Of that captured individuals, thereby permitting identification, sweep netting vastly outperformed passive methods, yielding total 1324 representing 131 units—even when deployed over shorter duration. each method differed according taxon. From analysis literature, there was high variability blue tended most effective, accordance with results from this study. However, present previous extremely low catch rates traps.

Planting gardens to support insect pollinators

Conservation Biology, Journal Year: 2018, Volume and Issue: 34(1), P. 15 - 25

Published: Dec. 29, 2018

Abstract Global insect pollinator declines have prompted habitat restoration efforts, including pollinator‐friendly gardening. Gardens can provide nectar and pollen for adult insects offer reproductive resources, such as nesting sites caterpillar host plants. We conducted a review meta‐analysis to examine how decisions made by gardeners on plant selection garden maintenance influence survival, abundance, diversity. also considered characteristics of surrounding landscapes the impacts natural enemies. Our results indicated that pollinators responded positively high species diversity, woody vegetation, size, sun exposure negatively separation habitats from sites. Within‐garden features more strongly influenced than landscape factors. Growing interest in gardening highlights need better understand gardens contribute conservation some enhance attractiveness usefulness pollinators. Further studies examining reproduction, resource acquisition, enemies comparing with other efforts are needed increase value human‐made

Mitigating the Effects of Habitat Loss on Solitary Bees in Agricultural Ecosystems

Solitary bees and other wild pollinators provide an important ecosystem service which can benefit both the agricultural economy sustainability of many native ecosystems. Many solitary bees, however, are experiencing decreases in their populations ranges, resulting overall loss pollinator species richness areas. Several interacting factors have been implicated this decline, including increased pesticide use, climate change, pathogens, but habitat remains one primary drivers. The widespread conversion natural habitats into landscapes has decreased availability adequate nesting sites floral diversity for bee species. Large monocultures with intensive production systems often cannot support (particularly short foraging ranges) necessary to ensure pollination animal-pollinated crops. Diversifying through incorporation wildflower plantings, as well preservation remaining habitats, may offer a solution, it shown increase abundance nearby In review article, we discuss various effects on different ways mitigate such order conserve landscapes.

Contrasting effects of vineyard type, soil and landscape factors on ground‐ versus above‐ground‐nesting bees

Abstract Agricultural intensification and abandonment of traditional agricultural practices are main drivers current insect declines. The resulting loss feeding nesting opportunities has led to a decrease in pollinator populations like wild bees. While the restoration floral resources been widely implemented bee conservation, resources, particularly for ground‐nesting species, barely considered. We assessed diversity wine‐growing area Germany 15 study sites along soil gradient evaluated whether bees were distinctly affected by different vineyard types (vertically oriented, terraced, abandoned), local conditions (e.g. shrub flower cover) landscape factors response divergent needs (above‐ground vs. ground‐nesting). found that responded more strongly availability than resources. determined suitability aspects irrespective management types, above‐ground‐nesting profited from encroachment fallows enhanced semi‐natural habitats (SNHs) surrounding landscape.
