Was there ever an Animal Dasein? Heidegger's Concept of Life in the 1924 Aristotle Lecture

European Journal of Philosophy, EarlyView.
Abstract This essay examines Heidegger's interpretation of the Aristotelian concept of life in his 1924 lecture Basic Concepts of Aristotelian Philosophy. While scholars have emphasized the text's decisive role in the preparation of Being and Time, their readings have largely centered on the notions of praxis and human existence.

Why we Should Study Solitary Species to Understand the Costs of Group‐Living

Ethology, EarlyView.
It's easier to measure the benefits than the costs of a trait. Solitary species benefit by avoiding the costs of group living. Thus, measuring benefits of solitary living informs us about the costs of group living. ABSTRACT While for decades behavioral ecologists have studied the benefits of group living, measuring its costs has been more difficult. It

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

Ibis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

New fungal core microbiome members of the ground nesting bee Andrena vaga: The key to oligolecty?

Basic and Applied Ecology
To fully understand a species, it is essential to gain knowledge about their associated (micro-)organisms. Currently, most research focuses on managed social bees and their bacterial associates.

Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

Insect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

The antibacterial activity of honey: 2. Variation in the potency of the antibacterial activity [PDF]

, 1992
Honey is gaining acceptance by the medical profession for use as an antibacterial agent for the treatment of ulcers and bed sores, and other surface infections resulting from burns and wounds. In many cases it is being used with success on infections not

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

Insect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

Acute Toxicity of Selected Insecticides on Apis mellifera and Ceratina smaragdula: Laboratory and Field Assessments

Sociobiology
Pollinators are vital to agricultural productivity, yet their populations are declining due to anthropogenic disturbances, including pesticide use. This study evaluated the acute toxicity of selected insecticides to two bee species, the honey bee (Apis ...

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.
