The gut microbiota, a complex ecosystem of microorganisms of different kingdoms, impacts
host physiology and disease. Within this ecosystem, inter-bacterial interactions and their …

Dietary restriction (DR) has long been viewed as the most robust nongenetic means to
extend lifespan and healthspan. Many aging-associated mechanisms are nutrient …

Gut bacteria can affect key aspects of host fitness, such as development, fecundity, and
lifespan, while the host, in turn, shapes the gut microbiome. However, it is unclear to what …

Radical lifespan disparities exist in the animal kingdom. While the ocean quahog can
survive for half a millennium, the mayfly survives for less than 48 h. The evolutionary …

Life history theory has become a prominent framework in the evolutionary social sciences,
and the concept of trade-offs, the cornerstone of life history theory in studies on non-human …

Organisms are locally adapted when members of a population have a fitness advantage in
one location relative to conspecifics in other geographies. For example, across latitudinal …

There is experimental evidence that microbiomes have a strong influence on a range of host
traits. Understanding the basis and importance of symbiosis between host and associated …

Background The immune system of adult mosquitoes has received significant attention
because of the ability of females to vector disease-causing pathogens while ingesting blood …

Early‐life conditions can have long‐lasting effects and organisms that experience a poor
start in life are often expected to age at a faster rate. Alternatively, individuals raised in high …

Costs of reproduction are seemingly ubiquitous across the animal kingdom, and these
reproductive costs are generally defined by increased reproduction leading to decreases in …
