Density dependence shapes life-history trade-offs in a food limited ungulate population

This study shows density dependence shapes life-history trade-offs and reproductive success distribution in Soay sheep populations.

Ecology and not phylogeny influences sensitivity to climate change in Muscicapidae Flycatchers in Eastern Himalayan and Indo-Burman hotspots

This study assesses how climate change affects the distribution of Muscicapidae Flycatchers, finding that habitat generalists are more sensitive to climate change than specialists, with no strong phylogenetic signal in sensitivity.

Social and environmental transmission spread different sets of gut microbes in wild mice

This study identifies distinct social and environmental transmission routes of gut microbes in wild mice using RFID tracking and microbiota analysis.

Investigating tri-trophic interactions using bio-energetic demographic models

The paper develops a bioenergetic demographic model to study tri-trophic interactions in Yellowstone, showing that wolf reintroduction reduced elk numbers and increased vegetation biomass.

Density dependent environments can select for extremes of body size

The paper develops size-structured models to explore how density dependence influences body size evolution, showing that gigantism or dwarfism depends on population maturity proportions and developmental trajectories.

Unravelling processes between phenotypic plasticity and population dynamics in migratory birds

This study investigates how the loss of staging habitats affects migration strategies and population dynamics in migratory birds through phenotypic plasticity.

Life histories as mosaics: plastic and genetic components differ among traits that underpin life-history strategies

The paper tests whether genetic and environmental factors differ in their influence on life-history traits across high- and low-predation guppy ecotypes, finding variation in trait control by genetics and environment.

Substantial intraspecific variation in energy budgets: biology or artefact?

The paper shows that DEB model parameters vary within species due to data types and biological differences, challenging interspecies comparisons but allowing valid comparisons when data types are accounted for.

Social networks strongly predict the gut microbiota of wild mice

This study shows social network structure predicts gut microbiota similarity in wild mice, with male interactions driving microbial transmission and hub individuals having more diverse microbiotas.

Distributions of LRS in varying environments

The paper examines how lifetime reproductive success (LRS) distributions vary in different environments using Roe deer data and stochastic models.

ENVIRONMENTAL PERTURBATIONS AND TRANSITIONS BETWEEN ECOLOGICAL AND EVOLUTIONARY EQUILIBRIA: AN ECO-EVOLUTIONARY FEEDBACK FRAMEWORK

The paper presents an eco-evolutionary feedback framework linking ecology and evolution through resource accrual traits, life history strategies, and population dynamics following environmental perturbations.

Dynamic Price and Breeder's equations for variable environments

The paper extends the Breeder's and Price equations to dynamic environments by incorporating time-dependent selection differentials and heritabilities from structured population models.

The genomic landscape of divergence across the speciation continuum in island-colonising silvereyes (Zosterops lateralis)

This study uses RAD-sequencing and simulations to analyze genomic divergence in silvereyes, finding limited support for genomic islands widening with time and divergence accumulating around selected loci.

Skewed distributions of LRS: beyond mean and variance

The paper develops tools to generate lifetime reproductive success (LRS) distributions from structured models and shows they align with observed data, explaining skewed LRS patterns and resolving a selection debate.

Do African savanna elephants (Loxodonta africana) eat crops because they crave micronutrients?

This study investigates whether African savanna elephants consume crops due to micronutrient deficiencies, finding crops provide higher phosphorus and other nutrients compared to natural forage.

Weak spatiotemporal response of prey to predation risk in a freely interacting system

This study examines whether elk adjust their space use to minimize predation risk by wolves in Yellowstone, finding little evidence of spatiotemporal avoidance behavior.

Predicting The Evolutionary Consequences Of Trophy Hunting On A Quantitative Trait

This study uses quantitative genetic models to show trophy hunting can cause evolutionary change in traits like horn length, but the predicted rates are much slower than previously reported statistical analyses suggest.

Modeling Adaptive and Non-adaptive Responses of Populations to Environmental Change

The paper develops models to predict population responses to environmental change by linking quantitative genetics with data-driven models, showing that evolutionary responses are slower than plastic ones and depend on plastic adaptiveness.

PREDICTING COEXISTENCE IN SPECIES WITH CONTINUOUS ONTOGENETIC NICHE SHIFTS AND COMPETITIVE ASYMMETRY

This paper develops a framework using Integral Projection Models to predict coexistence in species with continuous ontogenetic niche shifts and competitive asymmetry, showing multiple routes to coexistence based on niche shifts and competitive dynamics.
