G3: Genes, Genomes, Genetics, 2019 Alkali bees (Nomia melanderi) are solitary relatives of the halictine bees, which have become an important model for the evolution of social behavior, but for which few solitary comparisons exist.

Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Presentation: The Buzz About Bees: How They Improve Our Lives
, 2017 Bees play a key role in pollination, the transferring of pollen between flowers which allows plants to be fertilized and produce fruit. But not all bees live in colonies and few are extensively managed by humans.

Genomic insights into neonicotinoid sensitivity in the solitary bee Osmia bicornis.
PLoS Genetics, 2019 The impact of pesticides on the health of bee pollinators is determined in part by the capacity of bee detoxification systems to convert these compounds to less toxic forms.

Endothermy and thermoregulation in solitary bees
, 1990 This thesis examines the roles of endothermy and body size in the thermal biology of solitary bees (Hymenoptera: Apoidea) within the species Anthophora plumipes (Anthophoridae) Amegilla sapiens (Anthophoridae) and Creightonellafrontalis (Megachilidae), within the genus Anthophora, and over the Apoidea as a whole.

Agricultural and Forest Entomology, EarlyView.Pollinator‐targeted annual flower strips increase abundances of pollinators but also natural enemies and herbivores. Natural enemies and herbivores disperse in a taxon‐specific manner into nearby crops. Pest control by ground‐dwellers slightly increases in crop areas near the flower strips.

Agricultural and Forest Entomology, EarlyView.We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

Nesting behaviour and population genetics of solitary bees (Hymenoptera: Anthophila)
, 2013 My thesis is focused on nesting behaviour and population genetics of solitary bees. These two topics, although seemingly unrelated, bring much new information and thus contribute to the better understanding of solitary bee biology that is still ...

Reproductive Senescence in the Pollinator, Megachile rotundata
InsectsThe disposable soma theory posits that organisms allocate limited resources between reproduction, maintenance, and growth, resulting in trade-offs, particularly as they age.
