Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Enhancing cognitive processing therapy via stellate ganglion blocks: A pilot randomized trial

Journal of Traumatic Stress, EarlyView.
Abstract Although trauma‐focused psychotherapies, such as cognitive processing therapy (CPT), are effective treatments for posttraumatic stress disorder (PTSD), a substantial portion of individuals exhibit a diminished response. Stellate ganglion block (SGB), an anesthetic procedure targeting the sympathetic nervous system, has shown promise for PTSD ...

Effect of age class on the survivorship and spatial movement patterns of headstarted Texas horned lizards soft‐released into an urban population

The Journal of Wildlife Management, EarlyView.
When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...

Genotype characterization of Haematobia irritans from different Brazilian geographic regions based on randomly amplified polymorphic DNA (RAPD) analysis Caracterização genotípica de Haematobia irritans procedentes de diferentes regiões geográficas brasileiras baseada na análise do DNA polimórfico amplificado ao acaso (RAPD-PCR)

Pesquisa Veterinária Brasileira, 2007
Blood-sucking diptera are important parasites in bovine production systems, especially regarding confinement conditions. Haematobia irritans, the horn fly, is one of the most troublesome species within bovine production systems, due to the intense stress
