Downscaling future climate change projections over Puerto Rico using a non-hydrostatic atmospheric model Downscaling future climate change projections over Puerto Rico using a non-hydrostatic atmospheric model
We present results from 20-year “high-resolution” regional climate model simulations of precipitation change for the sub-tropical island of Puerto Rico. The Japanese Meteorological Agency Non-Hydrostatic Model (NHM) operating at a 2-km grid resolution is nested inside the Regional Spectral Model (RSM) at 10-km grid resolution, which in turn is forced at the lateral boundaries by the...

Temperate and tropical forest canopies are already functioning beyond their thermal thresholds for photosynthesis Temperate and tropical forest canopies are already functioning beyond their thermal thresholds for photosynthesis
Tropical tree species have evolved under very narrow temperature ranges compared to temperate forest species. Studies suggest that tropical trees may be more vulnerable to continued warming compared to temperate species, as tropical trees have shown declines in growth and photosynthesis at elevated temperatures. However, regional and global vegetation models lack the data needed to...

A comparative evaluation of crowding stress on muscle HSP90 and myostatin expression in salmonids A comparative evaluation of crowding stress on muscle HSP90 and myostatin expression in salmonids
Stress is a major factor that contributes to poor production and animal welfare concerns in aquaculture. As such, a thorough understanding of mechanisms involved in the stress response is imperative to developing strategies to mitigate the negative side effects of stressors, including the impact of high stocking densities on growth. The purpose of this study was to determine how the...

Land use diversification and intensification on elk winter range in Greater Yellowstone: A framework and agenda for social-ecological research Land use diversification and intensification on elk winter range in Greater Yellowstone: A framework and agenda for social-ecological research
Amenity migration describes the movement of peoples to rural landscapes and the transition toward tourism and recreation and away from production-oriented land uses (ranching, timber harvesting). The resulting mosaic of land uses and community structures has important consequences for wildlife and their management. This research note examines amenity-driven changes to social-ecological...

A social–ecological perspective for riverscape management in the Columbia River Basin A social–ecological perspective for riverscape management in the Columbia River Basin
Riverscapes are complex, landscape-scale mosaics of connected river and stream habitats embedded in diverse ecological and socioeconomic settings. Social–ecological interactions among stakeholders often complicate natural-resource conservation and management of riverscapes. The management challenges posed by the conservation and restoration of wild salmonid populations in the Columbia...

Infrared heater system for warming tropical forest understory plants and soils Infrared heater system for warming tropical forest understory plants and soils
The response of tropical forests to global warming is one of the largest uncertainties in predicting the future carbon balance of Earth. To determine the likely effects of elevated temperatures on tropical forest understory plants and soils, as well as other ecosystems, an infrared (IR) heater system was developed to provide in situ warming for the Tropical Responses to Altered Climate...

Beyond the edge: Linking agricultural landscapes, stream networks, and best management practices Beyond the edge: Linking agricultural landscapes, stream networks, and best management practices
Despite much research and investment into understanding and managing nutrients across agricultural landscapes, nutrient runoff to freshwater ecosystems is still a major concern. We argue there is currently a disconnect between the management of watershed surfaces (agricultural landscape) and river networks (riverine landscape). These landscapes are commonly managed separately, but there...

A guide to calculating habitat-quality metrics to inform conservation of highly mobile species A guide to calculating habitat-quality metrics to inform conservation of highly mobile species
Many metrics exist for quantifying the relative value of habitats and pathways used by highly mobile species. Properly selecting and applying such metrics requires substantial background in mathematics and understanding the relevant management arena. To address this multidimensional challenge, we demonstrate and compare three measurements of habitat quality: graph-, occupancy-, and...

Snake fungal disease in North America: U.S. Geological Survey updates Snake fungal disease in North America: U.S. Geological Survey updates
Snake fungal disease (SFD) results from a skin infection that has been documented only in snakes. Historically, reports of snakes with skin infections of unknown origin have been sporadic. Recently, the number of reported cases of skin infections in snakes has increased substantially. This emerging infectious disease, confirmed in numerous species of snakes, is caused by the fungus...

International migration patterns of Red-throated Loons (Gavia stellata) from four breeding populations in Alaska International migration patterns of Red-throated Loons (Gavia stellata) from four breeding populations in Alaska
Identifying post-breeding migration and wintering distributions of migratory birds is important for understanding factors that may drive population dynamics. Red-throated Loons (Gavia stellata) are widely distributed across Alaska and currently have varying population trends, including some populations with recent periods of decline. To investigate population differentiation and the...

Managing individual nests promotes population recovery of a top predator Managing individual nests promotes population recovery of a top predator
Threatened species are managed using diverse conservation tactics implemented at multiple scales ranging from protecting individuals, to populations, to entire species. Individual protection strives to promote recovery at the population‐ or species‐level, although this is seldom evaluated.After decades of widespread declines, bald eagles, Haliaeetus leucocephalus, are recovering...

Isotopic evidence that nitrogen enrichment intensifies nitrogen losses to the atmosphere from subtropical mangroves Isotopic evidence that nitrogen enrichment intensifies nitrogen losses to the atmosphere from subtropical mangroves
Nitrogen (N) enrichment can have large effects on mangroves’ capacity to provide critical ecosystem services by affecting fundamental functions such as N cycling and primary productivity. However, our understanding of excess N input effects on N cycling in mangroves remains quite limited. To advance our understanding of how N enrichment via water or air pollution affects mangroves, we...
