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...

USGS invasive carp database management and integration support USGS invasive carp database management and integration support
Invasive carp tracking, monitoring, and contracted removal will continue throughout the Illinois River and upper Mississippi River as part of an adaptive management effort to mitigate, control, and contain invasive carp. Other fish will also be tracked to maintain a holistic view of the transmitter distribution in the Upper IWW. To facilitate these actions, a need to compile and analyze...

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...

USGS telemetry project USGS telemetry project
Tagging bigheaded carp (i.e., Bighead Carp and Silver Carp) and surrogate fish species with acoustic transmitters has become an invaluable management tool in the Upper IWW (i.e., upper Illinois River, lower Des Plaines River, and the CAWS). For example, movement probabilities between adjacent navigation pools need to be estimated to parameterize models, such as the SEICarP Model—a...

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...

Field testing of an underwater acoustic deterrent system in a Marseilles pool gravel pit on the Illinois River Field testing of an underwater acoustic deterrent system in a Marseilles pool gravel pit on the Illinois River
Acoustic deterrent technologies are being developed to prevent the spread of invasive carp (Bighead Carp, Silver Carp, Grass Carp, and Black Carp) from the Mississippi River watershed to the Great Lakes. To assess this technology, field testing of the deterrent equipment and newly developed sound stimuli on wild invasive carp populations is essential. Large-scale experimental deployments...

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
