In my thesis, I examined impacts of nesting and floral resources on ground-nesting bee assemblages at nine ranch sites with differing grazing histories. Because ecological disturbances can strongly affect the availability foraging over time, also history for bees. sampled assemblages, a comprehensive array vegetation soil measures, abundance richness. used these data to determine (1) importance different habitat livestock bees (2) how influenced resources. found that sandier soils had greater richness bees, less compacted abundance. Contrary many other studies, bare ground was not important or Grazing did any measures habitat, negligible effects abundance, richness, community composition. My results suggest may be limiting especially in areas predominately clay types. this context, such more than resource availability. More research is necessary tease apart grassland management types through those findings highlight considering conservation restoration efforts.

Pollinator diversity is declining due to habitat loss, low quality, limited connectivity and intensification of agriculture in remaining high-value habitats within human-dominated landscapes, such as calcareous grasslands. Options increase the local area protected are often limited. Therefore, we asked how quality well agri-environmental schemes (AES) configuration surrounding landscape can contribute preservation pollinator diversity. We sampled bees, butterflies hoverflies 40 grasslands Germany, assessed effects grassland area, connectivity, agricultural configuration, AES on species richness abundance. While was an important predictor for bee butterfly richness, with strongest sizes endangered species, flower resources nesting sites characteristics small field size, high proportion organic fields other significantly enhanced responses differing among three studied taxa. In contrast expectations, flowering did not benefit communities conclude that improving combination targeted management effective measures promote highly fragmented grassland.

Abstract Wild solitary bees face a host of challenges from the simplification landscapes and biodiversity loss to invasive species urbanization. Pollinator researchers restoration workers thus far gave much attention increase flower cover reduce impact these anthropogenic pressures. Over 30% bee need nonfloral resources such as leaves resin for their survival reproduction. However, importance in ecology, particularly leafcutter bees, has received very little attention. Leafcutter have global distribution cut constructing brood chambers. We information (a) what use do not foraging (b) leaf plant traits community drive preference usage. To fill this gap recommend plants conservation, we examined 13,062 612 107 families distributed 165 communities nine towns/cities four south Indian states. The locations states was quite dissimilar, but had similar proportion native exotic plants. probability foraged is governed by its clade, family, nativity, dimension, width.

Abstract Land use change is a major driver of pollinator decline and loss pollination services. For plant interactions to persist in rapidly changing urban systems, co‐occurring species must share matching traits, including phenological, morphological, physiological traits. Thus, the knowledge trait among interacting plants pollinators can aid design habitats enhance conservation value green spaces, but this remains relatively understudied. Here, we review how facilitates persistence creation new plant–pollinator networks. We highlight four drivers facilitating restructuring networks through gain areas. also show different pathways by which traits affected urbanization. Furthermore, functional help predict novel environments, those exotic species. Finally, application management practices, sustainable spaces that will accommodate functionally diverse within matrix.

Abstract Native bee populations are generally in decline, and although their conservation needs recognised, habitat requirements for the majority of species remain unknown. Many construct nests underground, including native Australian Lasioglossum (Homalictus) dotatum . However, like most ground‐nesting bees, nesting ecology, particularly substrate preferences soil surface requirements, remains poorly understood. To address this knowledge gap, study examined whether L. prefers bare sand or amid rock gravel treatment influences nest‐site selection. Experiments were conducted using 24‐L pots Bassendean sand, placed near active aggregations. Ten had a layer gravel, while remaining 10 left bare. Within each treatment, half contained untreated steam‐treated to remove potential contaminants. This design tested certain conditions features when selecting nest sites. Results showed that female preferentially with over those suggesting cover may create more favourable environment by moderating temperature, retaining moisture, providing structural stability entrances. Additionally, females preferred possibly indicating factors associated soil, such as microbial presence organic residues, deter nesting. advances our understanding behaviour provides framework creating pollinator‐friendly spaces identifying key influence mechanisms driving preference unknown, highlighting need further research distinguish roles hygiene, properties chemical cues

Protecting diverse solitary ground-nesting bees remains a pivotal conservation concern. Ground-nesting are negatively impacted by anthropogenic land use change that often removes suitable nesting habitat from the landscape. Despite their enormous ecological and agricultural contributions to pollination, solitary, neglected, partly due significant obstacle of discovering exactly where these establish nests. To address this limitation, we have developed ‘community science’ project map aggregations globally. In certain locations, abundances reach astounding levels, sometimes in millions, but scarcely known. Utilizing iNaturalist platform, which permits geo-referencing site observations bee identification, providing public education seeking engagement document order understand requirements species open new opportunities for conservation. Conservation priorities may then unequivocally be directed areas high richness, nest densities, sites rare bees.
