Low‐intensity management benefits solitary bees in olive groves

Journal of Applied Ecology, Journal Year: 2019, Volume and Issue: 57(1), P. 111 - 120

Abstract One of the current challenges for applied ecologists is to understand how manage/restore agroecosystems in a sustainable and cost‐effective way. The intermediate landscape complexity hypothesis (ILCH) predicts that effectiveness agri‐environmental measures (AES) on biodiversity ecosystem services recovery often largest landscapes complexity. This has rarely been tested savanna‐like permanent agroecosystems. Focusing pollinators, we test ILCH at regional scale Mediterranean olive orchards, one most important world. We inferred abundance cavity‐nesting pollinators 40 paired orchards (extensively vs. intensively managed herbaceous cover) 20 localities selected across gradient. also studied different magnitudes local management switches may affect by considering organic intensive fields as extremes orchards. used 208 trap nests solitary bees measure colonization rates. Additionally, conducted pollinator surveys ascertain rate was representative proxy activity. Our results showed (a) changes rates due herb cover peaked complexity, with extensively rendering higher (b) Organic had than their control farms regardless (c) There highly significant correlation between nest density foraging flowers, which suggests good estimator Policy implications . maintenance ground (main orchards) investment allowing recuperation when targeting located fostering farming (still minority groves) conservation should be priority policymakers since its effects are beneficial any landscape.

Structural elements enhanced by retention forestry promote forest and non-forest specialist bees and wasps

Forest Ecology and Management, Journal Year: 2022, Volume and Issue: 529, P. 120709 - 120709

Retention forestry promotes certain forest structural elements to enhance biodiversity. It is unclear however what extent retention measures are suited the biodiversity of bees and wasps, how relationships promoted by may differ when habitat-based classifications accounted for. Here, we analyze abundance, diversity species richness non-forest specialist cavity-nesting wasps collected on 127 plots in southern Black Forest, Germany. Our aim was use classifications, or groupings based habitat occurrence evaluate effectiveness importance that prioritized biodiversity-focused conservation. We found canopy cover, stand complexity standing deadwood were principally important for with differing responses among classifications. Forest metrics composition related variables indicating greater feeding nesting resource availability, namely herb complexity. Non-forest primarily cover elevation while community structured only understory richness. results indicate considering specializations bee wasp communities meaningful evaluation elements. The presence arrangement these can be altered level management practices utilizing cascading effects changes, such as increasing sun exposed via opening, high stump during tree harvesting.

Nest aggregations of wild bees and apoid wasps in urban pavements: A ‘street life’ to be promoted in urban planning

Insect Conservation and Diversity, Journal Year: 2023, Volume and Issue: 17(2), P. 396 - 408

Published: Sept. 25, 2023

Abstract In the last 10 years, interest in nature‐based solutions and ecosystem services like pollination has increased profoundly with it need to gather knowledge about wild bees apoid wasp community dynamics, especially urban ecosystems. Research on how environment impacts conditions of nesting sites is relatively scarce. Recent observations Brussels‐Capital Region (BCR; Belgium) show that pavements can provide alternative opportunities for ground‐nesting Hymenoptera, such as wasps. Here, using a citizen science approach, we investigated richness species living under pavements, well their preferences sidewalk characteristics. A total 22 belonging families bees, digger wasps associated cleptoparasites were identified at 89 BCR (Belgium). Sandstone setts or concrete slabs, an unbound joint size around mm, found be best suitable species. The soil texture pavement contained mainly sandy particles. We propose management guidelines support bee highly urbanised areas. Our pave way further research field ecology highlight potential multifunctional designs promote not only climate adaptation but also biodiversity.

Local and landscape factors affect sunflower pollination in a Mediterranean agroecosystem

PLoS ONE, Journal Year: 2018, Volume and Issue: 13(9), P. e0203990 - e0203990

Published: Sept. 27, 2018

In Europe, the surface devoted to sunflower cultivation has expanded by ∼ 26% from 2006 2016. Theoretically, this implies an increasing demand for pollinators, while at same time, scientific reports claim that pollinator communities worldwide are threatened multiple stressors such as agrochemicals, loss of suitable habitats and habitat fragmentation. However, question arises is whether insect pollination still relevant modern varieties often highly self-fertile. Following recent studies which demonstrate surrounding land use composition may affect ecosystem service provisioning in cropped fields, study aims re-examining status disentangling effects local landscape variables on seed set oil content Central Italy. Commercial cultivars, regardless their degree self-fertility, showed increased when receiving adequate amounts cross-pollination; composition, though, was not affected cross-pollination events. Honey bees accounted vast majority pollinators ensuring overall pollination. Sunflower higher fields surrounded landscapes containing a greater abundance beehives, early flowering crops, urban areas woody linear elements; conversely, lower where herbaceous semi-natural dominated landscape. This information necessary science-based planning agricultural policies shows that, despite adoption self-fertile benefits crop productivity.

Abstract Most of the studies on learning in bees have focused foraging context; we know little about preferences and cognitive processes nest-site selection, especially solitary bees. The majority bee species are contrast to eusocial bees, bees’ cognition social information use remained largely unstudied. Solitary cavity-nesting mason ( Osmia spp.) an ideal system study interspecific nest choice wild as many share similar nesting requirements. Here, show that blue O. caerulescens ) orange-vented leaiana examine hallmarks parasitization nests red bicornis before deciding where establish their own nests. They were also presented with contextual cues (geometric symbols) could be linked by observational learning. Subjects subsequently had a site marked symbol matched, or did not match, one seen at parasitized healthy nest. We copied rejected examined manipulated exhibit successful unsuccessful nesting, respectively. conclude selection. In current theories coexistence, niche overlap between may dynamically change depending observed success surrounding individuals.
