Does Seasonality Affect the Nest Productivity, Body Size, and Food Niche of Tetrapedia curvitarsis Friese (Apidae, Tetrapediini)? [PDF]

Sociobiology, 2018
Tetrapedia curvitarsis Friese is a widely distributed species, frequently attracted by trap-nests. Previous studies have revealed a higher frequency of nesting in the wet season and dimorphism between the sexes, with females exhibiting larger body size ...

Nesting biology of four Tetrapedia species in trap-nests (Hymenoptera:Apidae:Tetrapediini)

Revista de Biología Tropical, 2005
The nests used in this study were obtained from trap-nests (tubes of cardboard and cut bamboo stems) placed on Santa Carlota Farm (Itaoca Section-IS, Santana Section-SS and Cerrado-Ce), Cajuru, SP, Brazil.

The genome of the solitary bee Tetrapedia diversipes (Hymenoptera, Apidae). [PDF]

G3 (Bethesda)
Abstract Tetrapedia diversipes is a Neotropical solitary bee commonly found in trap-nests, known for its morphological adaptations for floral oil collection and prepupal diapause during the cold and dry season. Here, we present the genome assembly of T.

Sustained Heatwaves Reshape the Phytoplankton-Zooplankton Community Structure in Freshwater Ecosystems: A Case Study of Shengjin Lake. [PDF]

Ecol Evol
The sustained heatwave has shaped the plankton community structure and led to high‐temperature domestication of some of the plankton. Plankton communities have the ability to resist heatwave stress. The sustained heatwave has altered the interrelationships between plankton.

Genome Variation in Three Anthophora Bee Species Reflects Divergent Demographic Histories. [PDF]

Mol Ecol
ABSTRACT Population genomics can reveal trends and drivers of biodiversity loss, but it is still unclear how best to use measures of genome variation to understand population vulnerability in insects. Here we study genome variation in three species of Anthophora bees that show contrasting population trends in northern Europe.

The evolution of floral sonication, a pollen foraging behavior used by bees (Anthophila). [PDF]

Evolution, 2018
Abstract Over 22,000 species of biotically pollinated flowering plants, including some major agricultural crops, depend primarily on bees capable of floral sonication for pollination services. The ability to sonicate (“buzz”) flowers is widespread in bees but not ubiquitous.

Pollinator size and its consequences: Robust estimates of body size in pollinating insects. [PDF]

Ecol Evol, 2019
Novel predictive allometric models for two dominant pollinating taxa, bees and hoverflies that consider biogeography, phylogeny, and sexual dimorphism. These models, along with existing allometric equations for pollinating insects, form the R package, "pollimetry." Abstract Body size is an integral functional trait that underlies pollination‐related ...

Floral oil collection by male Tetrapedia bees (Hymenoptera: Apidae: Tetrapediini) [PDF]

Apidologie, 2011
Several groups of solitary bees, known as oil-collecting bees, gather lipids from flowers that offer them as their main reward to pollinators. In the Neotropical region, oil-collecting bees belong to the tribes Centridini, Tapinotaspidini, and Tetrapediini (Apidae: Apinae). The floral oils collected by females of these groups are used as larval food or

The body size of the oil-collecting bee Tetrapedia diversipes (Apidae) [PDF]

Journal of Hymenoptera Research, 2015
The body size of bees can affect their fitness in many ways. There is an indirect relationship between the size of the mother and the size of her progeny. This is so because large mothers use larger nests and brood cells and have higher foraging capacity than small mothers, and consequently large mothers supply a larger amount of food to their larvae ...

Sublethal doses of imidacloprid and pyraclostrobin impair fat body of solitary bee Tetrapedia diversipes (Klug, 1810)

Environmental Pollution, 2022
Solitary bees present greater species diversity than social bees. However, they are less studied than managed bees, mainly regarding the harmful effects of pesticides present in agroecosystems commonly visited by them. This study aimed to evaluate the effect of residual doses of imidacloprid and pyraclostrobin, alone and in combination, on the fat body
