Shifting hotspots: Climate change projected to drive contractions and expansions of invasive plant abundance habitats Shifting hotspots: Climate change projected to drive contractions and expansions of invasive plant abundance habitats
Aim Preventing the spread of range-shifting invasive species is a top priority for mitigating the impacts of climate change. Invasive plants become abundant and cause negative impacts in only a fraction of their introduced ranges, yet projections of invasion risk are almost exclusively derived from models built using all non-native occurrences and neglect abundance information.Location...

Gopherus Agassizii (Mojave Desert Tortoise). nest depredation Gopherus Agassizii (Mojave Desert Tortoise). nest depredation
Nest site selection is an important determinant of clutch success and hatchling sex ratios in Gopherus agassizii, Mojave Desert tortoises (Spotila et al. 1994. Herpetol. Monogr. 8:103-116). G. agassizii lay eggs in or near the entrance of their burrows (Ennen et al. 2012. Copeia 2012:222-228) and females of both G. agassizii and G. morafkai, may reduce egg predation risk by remaining at...

A proposed methodology for conducting threats assessments within the Great Lakes Coregonines restoration framework A proposed methodology for conducting threats assessments within the Great Lakes Coregonines restoration framework
This document serves to fulfill the Coregonine Threats Assessment Science Team’s charge of providing a written recommendation for a methodology to conduct threats assessments for Great Lakes coregonines within the Coregonine Restoration Framework (CRF). Through a series of team meetings that included presentations by experts on five candidate threats assessment frameworks followed by...

Status and trends in the Lake Superior fish community, 2023 Status and trends in the Lake Superior fish community, 2023
The U.S. Geological Survey annually conducts fishery surveys across Lake Superior that describe trends in fish species occurrence and relative abundance to inform fisheries management and large lake ecology. In 2023, the Lake Superior fish community was sampled with daytime bottom and surface trawls at 51 nearshore locations in June and 31 offshore locations in July. Nearshore bottom...

Chapter 24 - Resilience-based challenges and opportunities for fisheries management in Anthropocene rivers Chapter 24 - Resilience-based challenges and opportunities for fisheries management in Anthropocene rivers
Few pristine rivers remain worldwide, as they are among the most anthropogenically modified ecosystems. We suggest the geomorphology, hydrology and ecology of Anthropocene rivers are fundamentally different from historical natural rivers. These changes challenge conventional fisheries management practices, suggesting the tools supporting fisheries management may require expansion so that

Examining current bias and future projection consistency of globally downscaled climate projections commonly used in climate impact studies Examining current bias and future projection consistency of globally downscaled climate projections commonly used in climate impact studies
The associated uncertainties of future climate projections are one of the biggest obstacles to overcome in studies exploring the potential regional impacts of future climate shifts. In remote and climatically complex regions, the limited number of available downscaled projections may not provide an accurate representation of the underlying uncertainty in future climate or the possible...

Blue snowflakes in a warming world: Karner blue butterfly climate change vulnerability synthesis and best practices for adaptation Blue snowflakes in a warming world: Karner blue butterfly climate change vulnerability synthesis and best practices for adaptation
This report—developed at the request of the United States Fish and Wildlife Service-led Karner Blue Butterfly Recovery Team by Recovery Team members and partners—provides a Karner blue butterfly climate change vulnerability synthesis, explores a range of potential responses, and presents best practices for climate change-informed conservation of the species. The three decades since the...
