Guppy MHC and microsatellite genotypes, gyrodactylid infection trials, and analysis code

Karl Phillips
Natural host populations differ in their susceptibility to infection by parasites, and these intra-population differences are still an incompletely understood component of host-parasite dynamics. In this study, we used controlled infection experiments with wild-caught guppies (Poecilia reticulata) and their ectoparasite Gyrodactylus turnbulli to investigate the roles of local adaptation and host genetic composition (immunogenetic and neutral) in explaining differences in susceptibility to infection. We found differences between our four study host populations that were consistent...

Earth’s deep oceans remains less well understood than the surface of Mars. Beaked whales (ziphiids) are among the most visible inhabitants of the abyss, due to their large size and worldwide distribution, yet their diversity and ecology remain obscure. We combine genomic and morphometric analyses to reveal a new Southern Hemisphere ziphiid species, Ramari’s beaked whale, Mesoplodon eueu, whose name is linked to the Indigenous people of the lands from which the species holotype and...

Inhibitory control, exploration behaviour and manipulated ecological context are associated with foraging flexibility in the great tit

Jenny Coomes, Gabrielle Davidson, Michael Reichert, Ipek Kulahci, Camille Troisi & John Quinn
​​​​​Organisms are constantly under selection to respond effectively to diverse, sometimes rapid, changes in their environment, but not all individuals are equally plastic in their behaviour. Although cognitive processes and personality are expected to influence individual behavioural plasticity, the effects reported are highly inconsistent, which we hypothesise is because ecological context is usually not considered. We explored how one type of behavioural plasticity, foraging flexibility, was associated with inhibitory control (assayed using a detour-reaching task)...

Latitudinal influence on gametogenesis and host-parasite ecology in a marine bivalve model

Reproduction and parasites have significant impacts on marine animal populations globally. This study aimed to investigate the associative effects of host reproduction and a host-parasite interplay on a marine bivalve, along a geographic gradient of latitude. Cockles Cerastoderma edule were sampled from five European sites (54°N to 40°N), between April 2018 and October 2019. A histological survey provided data on trematode (metacercaria and sporocyst life stages), prevalence and cockle stage of gametogenesis to assess the...

Biometric conversion factors as a unifying platform for comparative assessment of invasive freshwater bivalves

1. Invasive bivalves continue to spread and negatively impact freshwater ecosystems worldwide. As different metrics for body size and biomass are frequently used within the literature to standardise bivalve related ecological impacts (e.g. respiration and filtration rates), the lack of broadly applicable conversion equations currently hinders reliable comparison across bivalve populations. To facilitate improved comparative assessment amongst studies originating from disparate geographic locations, we report body size and biomass conversion equations for six invasive freshwater...

Cognition and covariance in the producer-scrounger game

Michael Reichert, Julie Morand-Ferron, Ipek Kulahci, Josh Firth, Gabrielle Davidson, Sam Crofts & John Quinn
1. The producer-scrounger game is a key element of foraging ecology in many systems. Producing and scrounging typically covary negatively, but partitioning this covariance into contributions of individual plasticity and consistent between individual differences is key to understanding population level consequences of foraging strategies. Furthermore, little is known about the role cognition plays in the producer-scrounger game. 2. We investigated the role of cognition in these alternative foraging tactics in wild mixed-species flocks of great...

Associations between metabolic traits and growth rate in brown trout (Salmo trutta) depend on thermal regime

Louise Archer
Metabolism defines the energetic cost of life, yet we still know relatively little about why intraspecific variation in metabolic rate arises and persists. Spatiotemporal variation in selection potentially maintains differences, but relationships between metabolic traits (standard metabolic rate (SMR), maximum metabolic rate (MMR), and aerobic scope) and fitness across contexts are unresolved. We show that associations between SMR, MMR, and growth rate (a key fitness-related trait) vary depending on thermal regime (a potential selective agent)...

Data and code for Heterogeneous selection on exploration behavior within and among West European populations of a passerine bird

Alexia Mouchet, Ella Cole, Erik Matthysen, Marion Nicolaus, John Quinn, Allison Roth, Joost Tinbergen, Kees Van Oers, Thijs Van Overveld & Niels Dingemanse
Heterogeneous selection is often proposed as a key mechanism maintaining repeatable behavioral variation (“animal personality”) in wild populations. Previous studies largely focused on temporal variation in selection within single populations. The relative importance of spatial versus temporal variation remains unexplored, despite these processes having distinct effects on local adaptation. Using data from >3500 great tits (Parus major) and 35 nest box plots situated within five West-European populations monitored over 4-18 years, we show that selection...
