Climate change is arguably the greatest challenge to conservation of our time. Most
vulnerability assessments rely on past and current species distributions to predict
future persistence but ignore species’ abilities to disperse through landscapes, which
may be particularly important in fragmented habitats and crucial for long-term persistence
in changing environments....

In this issue of The Condor: Ornithological Applications, Haig et al. (2014) summarize negative impacts of lead ammunition and fishing tackle on birds and discuss strategies for mitigating risks to wildlife and human health. Their Review raises an important set of questions for hunters, wildlife managers, and conservation scientists. Effective...
Diet quality influences ungulate population dynamics but is difficult to measure at fine temporal or spatial resolution using field-intensive methods such as fecal nitrogen (FN). Increasingly, the remotely sensed vegetation index NDVI is used to represent potential ungulate diet quality, but NDVI's relationship with diet quality has yet to be...

Connectivity models using empirically-derived
landscape resistance maps can predict potential
linkages among fragmented animal and plant populations.
However, such models have rarely been used to
guide systematic decision-making, such as identifying
the most important habitat patches and dispersal corridors
to protect or restore in order to maximize regional
connectivity. Combining...

Bighorn sheep (Ovis canadensis) were not known to live on Tiburón Island, the largest island in the Gulf of California and
Mexico, prior to the surprisingly successful introduction of 20 individuals as a conservation measure in 1975. Today, a stable
island population of ~500 sheep supports limited big game hunting...
