Data from: Microhabitat complexity influences fear acquisition in fathead minnows

Adam Crane, Maud Ferrari, Ita Rivera-Hernandez & Grant Brown
Habitat varies in structure, with animals often preferring a certain degree of microhabitat complexity that facilitates fitness-related activities such as predator avoidance. Environments with high predation risk can induce elevated baseline fear and neophobia in prey, but whether microhabitat complexity influences the acquisition of neophobia has yet to be reported. Here, we tested whether exposure to predation risk induces different levels of fear in microhabitats that differed in complexity. We exposed fathead minnows, Pimephales promelas,...

Data from: Population variation in density-dependent growth, mortality and their trade-off in a stream fish

Jean-Michel Matte, Dylan Fraser & James Grant
Important variation in the shape and strength of density-dependent growth and mortality is observed across animal populations. Understanding this population variation is critical for predicting density-dependent relationships in natural populations, but comparisons among studies are challenging as studies differ in methodologies and in local environmental conditions. Consequently, it is unclear whether: (1) the shape and strength of density-dependent growth and mortality are population-specific; (2) the potential trade-off between density-dependent growth and mortality differs among populations;...

Data from: Conservation through the lens of (mal)adaptation: concepts and meta-analysis

Alison Derry, Dylan Fraser, Steven Brady, Louis Astorg, Elizabeth Lawrence, Gillian Martin, Jean-Michel Matte, Jorge Octavio Negrín Dastis, Antoine Paccard, Rowan Barrett, Lauren Chapman, Jeffrey Lane, Chase Ballas, Marissa Close & Erika Crispo
Evolutionary approaches are gaining popularity in conservation science, with diverse strategies applied in efforts to support adaptive population outcomes. Yet conservation strategies differ in the type of adaptive outcomes they promote as conservation goals. For instance, strategies based on genetic or demographic rescue implicitly target adaptive population states whereas strategies utilizing transgenerational plasticity or evolutionary rescue implicitly target adaptive processes. These two goals are somewhat polar: adaptive state strategies optimize current population fitness, which should...
