Associations of 16-Year Population Dynamics in Range-Expanding Moths with Temperature and Years since Establishment

open access: yesInsects, 2023
Parallel to the widespread decline of plants and animals, there is also an ongoing expansion of many species, which is especially pronounced in certain taxonomic groups and in northern latitudes. In order to inform an improved understanding of population

Reducing bias in density estimates for unmarked populations that exhibit reactive behaviour towards camera traps

open access: yesMethods in Ecology and Evolution, 2023
Density estimates guide wildlife management, and camera traps are commonly used to estimate sizes of unmarked populations. Unfortunately, animals often alter their natural behaviour in the presence of camera traps, which may bias subsequent density ...

Consumptive and nonconsumptive effects of omnivorous tadpoles on aquatic invertebrate communities

open access: yesEcosphere, 2023
Consumptive effects (CEs) of predation have been well‐studied in most aquatic systems, but nonconsumptive effects (NCEs) on prey have only recently received limited attention.

Imperfect Estimation of Lepeophtheirus salmonis Abundance and Its Impact on Salmon Lice Treatment on Atlantic Salmon Farms

open access: yesFrontiers in Marine Science, 2021
Accurate monitoring of sea lice levels on salmon farms is critical to the efficient management of louse infestation, as decisions around whether and when to apply treatment depend on an estimation of abundance.

Biogeography and predictors of wildlife killed on roads at peninsular Florida State Parks

open access: yesEcology and Evolution, 2021
Wildlife‐vehicle collisions (WVCs) are a major source of wildlife mortality and should affect regional wildlife diversity and abundance, yet most WVC studies are locally scaled.

Comparing methods to estimate feral burro abundance

open access: yesWildlife Society Bulletin, 2023
Obtaining precise and unbiased estimates of feral burro (Equus asinus) abundance in the western United States is challenging due to their cryptic pelage and the rugged terrain they inhabit. Management agencies employ helicopter‐based, simultaneous double‐
