Wolves (Canis lupus) can exert top-down pressure and shape ecological communities through selective predation of ungulates beavers (Castor Canadensis). Considering their ability to predation, understanding wolf foraging decisions is critical predicting ecosystem level effects. Specifically, if wolves are optimal foragers, consumers that optimize tradeoffs between cost benefits prey acquisition, changes in these factors may lead switching or negative-density dependent selection with potential consequences for community stability. For wolves, affecting include vulnerability, risk, reward, availability which vary temporally. We described diet by frequency occurrence percent biomass characterized relation using remains found scats on Isle Royale National Park, Michigan, USA during May–October 2019–2020. used logistic regression estimate consumption over time. predicted temporal variation (vulnerability and/or availability) such as adult calf moose (Alces alces) beaver wolves’ diet. analyzed 206 identified 62% beaver, 26% moose, 12% other (birds, smaller mammals, wolves). Adult were more likely occur scat May, when poor condition following winter. Similarly, the calves peaked June–mid July parturition but before vulnerability declined they matured. In contrast, did not change time, possibly reflecting importance low handling items recently introduced lone paired wolves. Our results demonstrate plastic responsive acquisition theory. Temporal fluctuation influence role respond increased risk altering breeding behavior.

There are two main reasons for monitoring the population of forest animals. First, regular surveys reveal real state biodiversity. Second, they guarantee a prompt response to any negative environmental factor that affects animal and make it possible eliminate threat before permanent damage is done. The research objective was study potential drone planes equipped with thermal infrared imaging cameras large in conditions Siberian winter forests snow background at temperatures -5 °C -30 °C. surveyed territory included Salair State Nature Reserve Kemerovo Region, Russia.

Novel conservation interventions such as assisted migration or gene editing inevitably raise the specter of potential unintended consequences, which can then delay derail action. Underappreciated are very real costs inaction. The rate climate change and pace extinction continue to outstrip predictions (IPCC, 2019). current unprecedented environmental calls for more attention being given consequences failing intervene. While it is important plan risks any intervention, just mitigate carrying on with business usual in face increasingly severe threats. To counter focus we hope that catchphrase "Intended Consequences" will help keep intended benefits nature front-of-mind during a responsible planning process through various stages intervention monitoring. goal goes beyond identifying objectives evaluating success (sensu Brooks, Wright, & Sheil, 2009). Our rebalancing risk–benefit equation give additional consideration inaction intervention. Although often initially controversial, early stakeholder engagement, other best practices result generate nature. For example, Scottish Natural Heritage began consider reintroducing beavers, people raised would negatively impact farming, forestry, fisheries, particularly salmonids (Gaywood, 2017). Frustrating delays motivated unauthorized beaver releases prior formal reintroduction. A complicated aftermath resulted many ecosystem but also some land management conflict.
