Macroinvertebrate community responses to disturbance in a fragmented river with contrasting legacies of alteration Macroinvertebrate community responses to disturbance in a fragmented river with contrasting legacies of alteration

Flow is a critical factor determining the riverine ecosystem structure and function. Widespread hydrologic alteration, however, has impacted the ecological integrity of rivers in ways that are not well understood, including responses of biological communities to increasingly frequent and severe climatic disturbances. Our study compared the responses of invertebrate communities on woody...

Overcoming low detectability in snake conservation research: Case studies from the Southeast USA Overcoming low detectability in snake conservation research: Case studies from the Southeast USA

Goals of conservation research include detecting and monitoring changes in abundance, understanding species interactions, detecting extinction events of imperiled species, and detecting colonization events and spread of non-native species. Achieving these goals is difficult or impossible when the target species is rarely encountered or when the number of individuals detected is unrelated...

Adapting standardized trout monitoring to a changing climate for the upper Yellowstone River, Montana, USA Adapting standardized trout monitoring to a changing climate for the upper Yellowstone River, Montana, USA

Objective Long-term standardized monitoring programs are fundamental to assessing how fish populations respond to anthropogenic stressors. Standardized monitoring programs may need to adopt new methods to adapt to rapid environmental changes associated with a changing climate. In the upper Yellowstone River, Montana, biologists have used a standardized, mark-recapture monitoring protocol...

Scale-dependence in elk habitat selection for a reintroduced population in Wisconsin, USA Scale-dependence in elk habitat selection for a reintroduced population in Wisconsin, USA

Habitat selection is a critical aspect of a species' ecology, requiring complex decision-making that is both hierarchical and scale-dependent, since factors that influence selection may be nested or unequal across scales. Elk (Cervus canadensis) ranged widely across diverse ecoregions in North America prior to European settlement and subsequent eastern extirpation. Most habitat selection...

Effects of recent wildfires on giant sequoia groves were anomalous at millennial timescales: a response to Hanson et al. Effects of recent wildfires on giant sequoia groves were anomalous at millennial timescales: a response to Hanson et al.

Background The giant sequoia (Sequoiadendron giganteum [Lindley] Buchholz) of California’s Sierra Nevada recently suffered historically unprecedented wildfires that killed an estimated 13–19% of seed-bearing sequoias across their native range. Hanson et al. recently sought to characterize post-fire reproduction in two severely burned sequoia groves, but their two papers (1) inaccurately...
