MULTIFACETED DRIVERS OF PERFORMANCE VARIATION IN ANIMAL POPULATIONS: INVASIVE PREDATOR, RESOURCE AVAILABILITY AND HYBRIDIZATION
… of a native species in response to an alien predator. Italian agile frog embryos developed faster when exposed to the predator in laboratory condition and when collected in alien crayfish-invaded sites. This ontogenetic shift can be interpreted as a local adaptation to the alien predator and …

Overcoming evolutionary history: conditioning the endangered Barrens topminnow to avoid predation by the invasive Western mosquitofish
… once adaptive for an organism but no longer are. Invasive species are one cause of evolutionary traps, and the Barrens Topminnow (BTM), Fundulus julisia serves as an example of an imperiled species trapped by the introduction of an invasive predator: the Western Mosquitofish (WMF), Gambusia …

Impacts of non-native rainbow trout on stream food webs in the Cape Floristic Region, South Africa integrating evidence from surveys and experiments
Impacts of invasive predators may be influenced by whether or not native predators which function in the same way as the invasive predator exist in the recipient system. Impacts are expected to be strong in isolated systems lacking functionally similar predators because native species will be naïve …

Population Ecology of Invasive Lionfish (Pterois volitans/miles) in the South Atlantic Bight
Invasive species are a top threat to global biodiversity. Lionfish (Pterois volitans/miles) are a marine invasive predator that are now established in the Western Atlantic, Caribbean Sea and Gulf of Mexico. Studies that have documented impacts of lionfish suggest they can reduce fish recruitment …

Interactions between two invasive crab predators, Carcinus maenas and Hemigrapsus sanguineus, and consequences for the native community
… into novel habitats at an accelerating rate. As invasive species become more common, interactions between invasive species will also increase and may alter the way that these species impact invaded communities. The European green crab Carcinus maenas is an aggressive predator that was introduced …

Ecology of feral cats Felis catus and their prey in relation to shrubland fire regimes
Invasive predators are major drivers of global biodiversity loss and their impacts may be worsened by other disturbances such as fire. I examined how the fire history of shrublands influences the ecology of feral cats Felis catus, dingoes Canis dingo and their prey species in Western Australia’s …

Morphological, Genetic, and Ecological Insights into the Puerto Rican Tody: Investigating Variation Between and Within Dry Forest and Rainforest Populations
… from climate change, forest fragmentation, and invasive predators, making it a valuable system for understanding how environmental change shapes island birds. Incorporating morphology, population genetics, disease ecology, and breeding ecology, this research provides an integrated view of how …
