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 ...

The Journal of Wildlife Management, EarlyView.Caribou forage lichens were present in post‐burn lodgepole pine stands multiple decades before stem‐density was likely open enough to attract wintering caribou. We posit that the prolonged self‐thinning of lodgepole pine after fire may be a greater limiting factor than lichen abundance for habitat recovery in lodgepole pine forests.

Northern bobwhites associated with native grass and shrubs have improved survival
The Journal of Wildlife Management, EarlyView.Survival rates of adult northern bobwhites were improved by a combination of grazed native warm‐season grasses and well‐interspersed shrubs. Our study suggests that incorporating native warm‐season grass cattle forages into existing operations across the southeastern United States may be a viable working‐lands conservation strategy to create habitat ...

Physiological traits explain the response of dung beetles to land use at local and regional scales
Scientific ReportsPhysiological traits in insects are useful to understand their distribution at different spatial scales, their presence and abundance, and the use of different habitats.

Advances in research on autophagy in the maintenance of insect–microbe symbiosis
New Plant Protection, EarlyView.Autophagy plays a dual regulatory role in insect–microbe symbiotic relationships. Beneficial symbiotic bacteria in insects participate in nutrient exchange via the TOR pathway, whereas pathogenic microbes induce immune defense through the AMPK pathway. Autophagy‐related genes regulate development and pathogen clearance during this process.

Otolaryngology–Head and Neck Surgery, EarlyView.Abstract Objective To quantify the cumulative number of images needed to scan (NNS) with preoperative high‐resolution temporal bone computed tomography (HR‐TBCT) to yield a change in management in patients undergoing primary stapes surgery for otosclerosis‐related hearing loss. Study Design Retrospective cohort.

Seed size and pubescence facilitate secondary dispersal by dung beetles
In tropical forests, primary dispersal by animals is the most important form of seed dispersal. Dung beetles are secondary seed dispersers attracted to mammal feces.

Effect of Dung Beetles on Dung Decomposition and Nuntrient Cycling in a Nebraska Rangeland [PDF]
, 2016 Management practice can have impacts on the abundance and frequency of dung beetle populations and nutrient cycling in grazing systems. Also, agriculture and livestock production land use is a considerable source of anthropogenic greenhouse gas (GHG ...

Coverage‐based rarefaction fails to quantify relative species richness
Oikos, EarlyView.Coverage‐based rarefaction (CBR) is a high‐profile tool for assessing biodiversity that provides relative species richness estimates by leveraging the Good‐Turing index u to interpolate. In contrast to alternatives such as the Shannon and Simpson indices, CBR's main appeal is providing values in units of species. CBR is tested against a series of other
