Animals respond to competition among kin for critical breeding resources in two ways: avoidance of direct fitness costs via dispersal siblings breed separately, and formation kin-based societies which subordinates offset altruism increased indirect fitness. In the facultatively social eastern carpenter bee, nests are a resource perpetually short supply, leading strong females. Observations indi...

Many wild bee species are declining globally. To design efficient mitigation strategies to slow down or reverse these trends, we urgently need better understand their basic ecological requirements. In this context, studied two specialist for which data scarce: Dasypoda visnaga and maura . We provide the first-time detailed information on phenologies, morphological traits, floral preferences, ne...

Abstract In this study, we describe the first reported nest of Bombus morrisoni , a species with an extensive range in arid Intermountain Region Nearctic. The mature, naturally terminated consisted 424 cells (cocoons), 328 non-gyne and 94 gyne cells. also had two kinds understudied structures associated bumble bee nests: pollen columns wax canopy. We found five rising amid cocoons. A 0.3-mm-thi...

Observations on a nesting aggregation of Perdita (Perdita) difficilis in south eastern Arizona indicate that this species is solitary, provisions two cells per day during two foraging periods (0700-1000 and 1700-1930 hr) and requires only three trips (two with pollen and one with nectar, in that order) to provision a cell. Nests are occupied for less than 5 days and bees most likely occupy seve...

Abstract Bees are important insects both environmentally and economically. Despite this, most bee species poorly characterized regarding their morphology nesting habits, which relevant characteristics for planning management conservation. Plebeia flavocincta is a stingless that occurs in the Northeast region of Brazil there little knowledge about its biology. Here, we morphologically characteri...

One of the most important micro engineers of the terrestrial ecosystems, especially in the arid areas is the harvester ants due to their activity in the soil through nest building; they can make major changes while influencing the surface and subsurface in the rangeland soil. The purpose of this study was to investigate the effects of harvester ants (Messor spp.) on some soil properties in Rood...
