Compensatory recruitment unlikely in high-elevation amphibian populations challenged with disease

Understanding the causes of population variation in host response to disease, and the mechanisms of persistence, can serve as vital information for species conservation. One such mechanism of population persistence that has gained support is the demographic process of compensatory recruitment. Host populations may persist by increasing recruitment to compensate for reduced survival due to infectio

A targeted annual warning system developed for the conservation of a sagebrush indicator species

A fundamental goal of population ecologists is to identify drivers responsible for temporal variation in abundance. Understanding whether variation is associated with environmental stochasticity or anthropogenic disturbances, which are more amenable to management action, is crucial yet difficult to achieve. Here, we present a hierarchical monitoring framework that models rates of change in abundan

Forecasting natural regeneration of sagebrush after wildfires using population models and spatial matching

ContextAddressing ecosystem degradation in the Anthropocene will require ecological restoration across large spatial extents. Identifying areas where natural regeneration will occur without direct resource investment will improve scalability of restoration actions.ObjectivesAn ecoregion in need of large scale restoration is the Great Basin of the Western US, where increasingly large and frequent w

Organic Contaminants in Reuse Waters and Transport Following Land Application

Potential reuse waters contained unique mixtures of organic contaminants with the greatest number detected in treated municipal wastewater treatment plant effluent, followed by urban stormwater, and agricultural runoff. This study provided information for decisions on reuse strategies to support freshwater supplies.

Expanding Distribution of Chronic Wasting Disease

Chronic wasting disease (CWD) has been detected in 30 US states and four Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 29 states and three provinces and in captive cervid facilities in 18 states and three provinces.
