Digestion and assimilation of nutrients and energy is central to survival. At its most basic
level, investigations of digestion in animals must examine digestive efficiency, or how much …

Fish biologists have long assumed a link between intestinal length and diet, and relative gut
length or Zihler's index are often used to classify species into trophic groups. This has been …

Teleost omnivorous fish that coexist partially sharing resources are likely to modify their gut
traits and microbiome as a feedback mechanism between ecological processes and …

Alterations to ratios of protein and fiber in an organism's diet have been shown to structurally
and functionally alter its individual digestive physiology. However, it is unclear how these …

Abalone around the world are subject to increasing frequency of marine heatwaves, yet we
have a limited understanding of how acute high temperature events impact the physiology of …

Simple Summary Heterotis niloticus is a primitive freshwater teleost. It is a candidate for
aquaculture in Africa with a good conversion rate and is used for evolutionary studies for its …

Digestion is driven by digestive enzymes and digestive enzyme gene copy number can
provide insights on the genomic underpinnings of dietary specialization. The “Adaptive …

Environmental RNA (eRNA) is an emerging technique with significant potential for the
assessment of organismal function in field settings. It has the advantage of being non …

What an animal ingests and what it digests can be different. Thus, we examined the
nutritional physiology of Lumpenus sagitta, a member of the family Stichaeidae, to better …

What an animal eats and how it digests its food determines that animal's contribution to its
ecosystem. However, the nutritional physiology (including digestion) of animals is commonly …
