Field evaluations of thermal optics and tracking tunnels for small mammal surveys at airports and grass dominated habitats

Wildlife Society Bulletin, EarlyView.
Small mammal survey tools are needed at airports to help inform aircraft strike‐risk management. We evaluated thermal optics and tracking tunnels as small mammal survey tools. We conclude that thermal optics would not be a viable survey tool for mouse‐sized mammals (19‐41 g) at airfields and other thick grass habitats unless grass height was maintained

Asymptotic properties of equilibrium in discriminatory and uniform price ipv multi-unit auctions [PDF]

This paper confronts the tractability problems that accompany IPV auction models with multi-unit bidder demands. Utilizing a first order approach, the asymptotic properties of symmetric equilibria in discriminatory and uniform price auctions are derived.

Facing Truths About Population Management

Zoo Biology, EarlyView.
Populations of wildlife, and domestic animals have large sinks for surplus animals. By contrast, zoos don't. Humans in industrialized societies are socialized with companion animals, i.e. surplus (i.e., typically denied reproduction) originating from unseen breeding cores.

The Process of Unit Price Extraction from Public Sector Contracts

, 2020
Czech government institutions commissioned a research on extracting usual unit prices from public IT contracts to aid future public tender sizing. The goal of the project is to obtain millions of contracts from the public register, convert them to full ...

Bridging the divide between models of animal‐driven and microbial‐driven biogeochemical cycling: A zoogeochemistry‐informed framework

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Most current terrestrial biogeochemical models formalize biogeochemical cycling as predominantly controlled by processes involving plants and soil microbes. However, growing evidence indicates that above‐ground animals could exert controlling feedback effects that alter

Market Signals Transmitted by Grid Pricing [PDF]

Grid pricing improves the flow of information to producers, but market signals sent by grids may not be clearly understood. This study uses a two-stage Coefficients of Separate Determination process, four sets of fed cattle carcass data, and sensitivity ...

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric

Large parameter uncertainty persists in soil food web models integrating stoichiometry, respiration and assimilation

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil food web models are essential for linking animal diversity to carbon and nutrient cycling. However, it is unclear how soil animals regulate excess carbon when nutrient availability limits their growth and how to best represent animal respiration in these models. To

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

Journal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...
