Freezing ovarian fluid does not alter how it affects fish sperm swimming performance: creating a cryptic female choice ‘spice rack’ for use in split‐ejaculate experimentation by Purchase, Craig F., Rooke, Anna C.

“…Cryptic female choice is often mediated chemically in external fertilizers by ovarian fluid (OF), which can change sperm swimming performance and bias…”

The winter munchies: feeding throughout winter is common in juvenile Pumpkinseed and improves energy reserves available in spring by Rooke, Anna C., Fox, Michael G.

“…In warmwater fishes, feeding during winter is often assumed to be negligible; however, there is growing evidence that juveniles will feed opportunistically…”

Population density contributes to the higher functional response of an invasive fish by Paton, Rebecca A., Gobin, Jenilee, Rooke, Anna C., Fox, Michael G.

“…Invasive species often have higher functional responses than native analogs. A better understanding of the functional response of invasive species could help…”

A synthesis of senescence predictions for indeterminate growth, and support from multiple tests in wild lake trout by Purchase, Craig F, Rooke, Anna C, Gaudry, Michael J, Treberg, Jason R, Mittell, Elizabeth A, Morrissey, Michael B, Rennie, Michael D

“…Senescence-the deterioration of functionality with age-varies widely across taxa in pattern and rate. Insights into why and how this variation occurs are…”

A common environment experiment reveals plastic and genetic contributions to the fast life‐history strategy of an invasive fish by Rooke, Anna C., Fox, Michael G.

“…Invasive species often exhibit a suite of life‐history traits that promote rapid population growth, including early age and small size at maturation, and high…”

Assessing the potential for post‐ejaculatory female choice in a polyandrous beach‐spawning fish by Orbach, Dara N., Rooke, Anna C., Evans, Jonathan P., Pitcher, Trevor E., Purchase, Craig F.

“…In species with limited opportunities for pre‐ejaculatory sexual selection (behavioural components), post‐ejaculatory mechanisms may provide opportunities for…”

Living a century in warm thermal conditions: introduced populations of Pumpkinseed (Lepomis gibbosus) inhabiting the Iberian Peninsula (Spain) show reduced adaptation to North American winter conditions by Rooke, Anna C, Fox, Michael G

“…In this study, we demonstrate that non-native Pumpkinseed (Lepomis gibbosus) introduced into Spanish water-bodies almost 100 years ago have a reduced capacity…”

Morphological change and phenotypic plasticity in native and non-native pumpkinseed sunfish in response to competition by Yavno, Stan, Rooke, Anna C, Fox, Michael G

“…Non-indigenous species are oftentimes exposed to ecosystems with unfamiliar species, and organisms that exhibit a high degree of phenotypic plasticity may be…”
