Abstract:
... Protected areas are established for diverse conservation strategies, but their effectiveness for conserving species varies widely. We compiled studies that used telemetry to determine cause-specific mortality of North American mammals and compared mortality sources of animals monitored in areas classified as protected by the International Union for Conservation of Nature and non-protected areas. O ...

Abstract:
... A new species of Macrosiphum Passerini is described from western North America based on the apterous and alate viviparous females. Macrosiphum glawatz n. sp. lives on Potentilla gracilis (Rosaceae), apparently without host alternation, being commonly attended by ants in the genus Formica L. Details are provided regarding its similarity to other Macrosiphum, especially Macrosiphum mentzeliae Wilson ...

Abstract:
... China has different topographic conditions and multiple weather systems due to its vast geographic areas. As a result, the geographic diversity between different provinces is potential to mitigate wind power variability. This study analyzes the spatial and temporal correlations of wind power on the province level. The results show that a lower correlation is observed for greater distances and smal ...

We aimed to identify parasites infecting PNC individuals through paleoparasitological and pale ...

Abstract:
... Climate connectivity, the ability of a landscape to promote or hinder the movement of organisms in response to a changing climate, is contingent on multiple factors including the distance organisms need to move to track suitable climate over time (i.e. climate velocity) and the resistance they experience along such routes. An additional consideration which has received less attention is that human ...

Climate change can affect the habitat resources available to species by changing habitat quantity, suitability and spatial configuration, which largely determine population persistence in the landscape. In this context, dispersal is a central process for species to track their niche. Assessments of the amount of reachable habitat (ARH) using static snap‐shots do not account, however, for the tempo ...

Abstract:
... The use of proxy exposure estimates for PM₂.₅ and NO₂ in air pollution studies instead of personal exposures, introduces measurement error, which can produce biased epidemiological effect estimates. Most studies consider total personal exposure as the gold standard. However, when studying the effects of ambient air pollution, personal exposure from outdoor sources is the exposure of interest.We as ...

Tree diameter increment (ΔDBH) is a key component of a forest growth and yield model as predictions are passed to other submodels and tree-level estimates are scaled up to represent plot- and stand-level measures. A common problem faced in mixed-species stands is that ΔDBH needs to be characterized for numerous species, each with varying growth rates, shade tolerances, and competitive abilities. I ...

Christ applied the name Aspidium × arendsii to this hybrid. In the following decades the ...

The southern outlet is the oldest and best understood ou ...

In the context of climate change and projected increase in global temperature, the atmosphere’s water holding capacity is expected to increase at the Clausius-Clapeyron (C-C) rate by about 7% per 1 °C warming. Such an increase may lead to more intense extreme precipitation events and thus directly affect the probable maximum precipitation (PMP), a parameter that is often used for dam safety and ci ...
