Life-History Evolution and the Genetics of Fitness Components in Drosophila melanogaster
T Flatt - Genetics, 2020 - academic.oup.com
Life-history traits or “fitness components”—such as age and size at maturity, fecundity and
fertility, age-specific rates of survival, and life span—are the major phenotypic determinants …

Learning to starve: impacts of food limitation beyond the stress period
Starvation is common among wild animal populations, and many individuals experience
repeated bouts of starvation over the course of their lives. Although much information has …

Assessment of trade-offs between feed efficiency, growth-related traits, and immune activity in experimental lines of layer chickens
T Zerjal, S Härtle, D Gourichon, V Guillory… - Genetics Selection …, 2021 - Springer
Background In all organisms, life-history traits are constrained by trade-offs, which may
represent physiological limitations or be related to energy resource management. To detect …

Dietary restriction and life-history trade-offs: insights into mTOR pathway regulation and reproductive investment in Japanese quail
Resources are needed for growth, reproduction and survival, and organisms must trade off
limited resources among competing processes. Nutritional availability in organisms is …

Investment in regeneration versus asexual reproduction is resource‐dependent in a freshwater annelid
The post‐embryonic developmental processes of regeneration and asexual agametic
reproduction are widespread and often co‐occur in animals. These traits are of great …

Resting metabolic rates increase with elevation in a mountain‐dwelling lizard
Individuals that inhabit broad elevational ranges may experience unique environmental
challenges. Because temperature decreases with increased elevation, the ectotherms living …

How much energetic trade‐offs limit selection? Insights from livestock and related laboratory model species
F Douhard, M Douhard, H Gilbert… - Evolutionary …, 2021 - Wiley Online Library
Trade‐offs between life history traits are expected to occur due to the limited amount of
resources that organisms can obtain and share among biological functions, but are of least …

Trade-off shapes diversity in eco-evolutionary dynamics
We introduce an Interaction-and Trade-off-based Eco-Evolutionary Model (ITEEM), in which
species are competing in a well-mixed system, and their evolution in interaction trait space is …

Optimal resource allocation and its consequences on behavioral strategies, personality traits and preferences
Life history theory is increasingly invoked in psychology as a framework for understanding
differences in individual preferences. In particular, evolutionary human scientists tend to …
