The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

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.

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

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 ...

Increased overwintering temperature reduces reproductive success of the solitary bee species Osmia bicornis

Scientific Reports
Solitary wild bees play a key role as pollinators of wild plants and crops, but they are increasingly at risk from anthropogenic global change, such as climate warming.

Comparative temporal response of toxicity for the neonicotinoid clothianidin and organophosphate dimethoate insecticides in two species of solitary bee (Osmia bicornis and Osmia cornuta)

Ecotoxicology and Environmental Safety
Solitary bees provide essential pollination services. Concerns for the decline of these wild bee species have led to calls for their inclusion in pesticide risk assessment. Solitary bees differ from honey bees in their physiology and ecology and this may

Susceptibility of solitary bees to agrochemicals highlights gaps in bee risk assessment

Environmental Toxicology and Pharmacology
Ground-nesting solitary bees are the most abundant bee species in the xeric areas of the world, but the effects of agrochemicals on them have been little studied. Herein, we evaluated the topical toxicity of an insecticide, a herbicide, and an essential oil on Mediterranean ground-nesting bees (Andrena impunctata, A. nigroolivacea, A.

Significant Far‐Right Challenges to Australian Society? The XYZ and AustraliaOne

Australian Journal of Politics &History, EarlyView.
ABSTRACT Scholars who analyse the Australian far‐right from a criminological or security studies perspective propose that activists and groups pose ‘political’ challenges to Australian society. This paper examines the far‐right news website The XYZ and the AustraliaOne political party, and argues that claims that the far‐right may normalise ...

Injustice, relational violence, and the foster system

American Journal of Political Science, EarlyView.
Abstract Political theorists have not paid sustained attention to the foster system or treated it as a political institution. Despite this, scholars and social movement advocates have identified the system as a site of social and political injustice. This paper develops an account of racial, class, and relational injustice in the contemporary US foster

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

Archaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.
