A new water temperature modeling approach to predict thermal habitat suitability for nonnative cichlids in Florida rivers A new water temperature modeling approach to predict thermal habitat suitability for nonnative cichlids in Florida rivers
As global temperatures increase, the spatiotemporal arrangement of thermal habitats in Florida rivers may shift, creating the potential for greater dispersal and establishment of nonnative tropical freshwater fishes. To understand how water temperature changes may affect the spatial distribution of these nonnative species, more effective water temperature prediction models are necessary...

Phenotypic homogenization and potential fitness constraints following non-native introgression in an endemic sportfish Phenotypic homogenization and potential fitness constraints following non-native introgression in an endemic sportfish
Introgressive hybridization may lead to contrasting evolutionary outcomes that are difficult to predict since they depend on the fitness effects of endogenous genomic interactions and environmental factors. Conservation of endemic biodiversity may be more effective with require direct measurement of introgressed ancestry and fitness in wild populations, especially for keystone taxa at...

Droughts reshape apex predator space use and intraguild overlap Droughts reshape apex predator space use and intraguild overlap
1. Droughts are increasing in frequency and severity globally due to climate change, leading to changes in resource availability that may have cascading effects on animal ecology. Resource availability is a key driver of animal space use, which in turn influences interspecific interactions like intraguild competition. Understanding how climate-induced changes in resource availability...

Juvenile coho salmon growth differences track biennial pink salmon spawning patterns Juvenile coho salmon growth differences track biennial pink salmon spawning patterns
1. Spawning Pacific salmon (Oncorhynchus spp.) provide marine-derived resources (MDR) to freshwater food webs in the form of eggs, flesh and maggots that consume salmon carcasses, all of which positively impact stream-dwelling fish growth. Pink salmon (O. gorbuscha) are widely distributed throughout coastal catchments along the North Pacific Ocean and display increased spawning...

Penguin colony georegistration using camera pose estimation and phototourism Penguin colony georegistration using camera pose estimation and phototourism
Satellite-based remote sensing and uncrewed aerial imagery play increasingly important roles in the mapping of wildlife populations and wildlife habitat, but the availability of imagery has been limited in remote areas. At the same time, ecotourism is a rapidly growing industry and can yield a vast catalog of photographs that could be harnessed for monitoring purposes, but the inherently...

Spatial distribution patterns of invasive silver carp can inform removal efforts in an oxbow lake of the Mississippi River Spatial distribution patterns of invasive silver carp can inform removal efforts in an oxbow lake of the Mississippi River
Oxbow lakes are highly productive waterbodies that host multiple life stages of many freshwater aquatic species. These lakes also provide foraging and rearing habitat to the invasive silver carp (Hypophthalmichthys molitrix) enabling populations to grow in biomass and abundance that can add propagule pressure to connected waterways and oxbows within the Mississippi River Basin...

The influence of grazing on the spatiotemporal activity patterns of a primary sage-grouse nest predator The influence of grazing on the spatiotemporal activity patterns of a primary sage-grouse nest predator
Perturbations in ecological processes can occur when wildlife alter their spatiotemporal activity patterns to avoid human activities that they perceive as a risk. Such perturbations can have cascading effects throughout wildlife communities. For greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse), nest predation plays an important role in population dynamics. Domestic...

Predator-specific mortality of sage-grouse nests based on predator DNA on eggshells Predator-specific mortality of sage-grouse nests based on predator DNA on eggshells
Greater sage-grouse (hereafter sage-grouse; Centrocercus urophasianus) populations have declined across their range. Increased nest predation as a result of anthropogenic land use is one mechanism proposed to explain these declines. However, sage-grouse contend with a diverse suite of nest predators that vary in functional traits (e.g., search tactics or hunting mode) and abundance...
