Data from: Estimating the intensity of use by interacting predators and prey using camera traps

Jonah L. Keim, Subhash R. Lele, Philip D. DeWitt, J. Jeremy Fitzpatrick & Noemie S. Jenni
Understanding how organisms distribute themselves in response to interacting species, ecosystems, climate, human development and time is fundamental to ecological study and practice. A measure to quantify the relationship among organisms and their environments is intensity of use: the rate of use of a specific resource in a defined unit of time. Estimating the intensity of use differs from estimating probabilities of occupancy or selection, which can remain constant even when the intensity of use...

Data from: Road avoidance and its energetic consequences for reptiles

Roads are one of the most widespread human-caused habitat modifications that can increase wildlife mortality rates and alter behaviour. Roads can act as barriers with variable permeability to movement and can increase distances wildlife travel to access habitats. Movement is energetically costly, and avoidance of roads could therefore impact an animal's energy budget. We tested whether reptiles avoid roads or road crossings and explored whether the energetic consequences of road avoidance decreased individual fitness. Using...

Data from: Pop‐off data storage tags reveal niche partitioning between native and non‐native predators in a novel ecosystem

Graham D. Raby, Timothy B. Johnson, Steven T. Kessel, Thomas J. Stewart & Aaron T. Fisk
1. Niche partitioning might be predicted to be particularly dynamic in ‘novel ecosystems’ characterized by human-altered environmental conditions and biological invasions. Restoration efforts for native species in such systems can be informed by detailed characterization of niche partitioning. 2. In Lake Ontario, fishery management agencies have been engaged in a long-term struggle to restore native top predators including lake trout (Salvelinus namaycush). Meanwhile, management agencies continue to stock non-native species like Chinook salmon (Oncorhynchus tshawytscha)...

Data from: New and Old World phylogeography of pumpkinseed (Lepomis gibbosus): the North American origin of introduced populations in Europe

Stan Yavno, Jenilee Gobin, Chris C Wilson, Anna Vila-Gispert, Gordon H Copp & Michael Fox
To determine the origin of introduced European populations of pumpkinseed (Lepomis gibbosus) – a freshwater sunfish, native to eastern North America that has spread across western and central Europe – we investigated the phylogeography of the species by sequencing the mitochondrial NADH subunit 1 gene. A total of 543 pumpkinseed were sampled from 32 sites across the native range of the species, and from 19 sites covering much of its introduced European range. The presence...
