Heat limits scale with metabolism in ectothermic animals
Journal of Animal Ecology, Volume 94, Issue 6, Page 1307-1316, June 2025.We show that the extent to which ectotherms can increase their heat limits is strongly linked to how metabolic rate scales with temperature. This is a new perspective on what sets temperature limits in organisms, and will be important for understanding and predicting how different animals will respond to future warming.

Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]
, 1987 The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark,

Fuzzy species limits in Mediterranean gorgonians (Cnidaria, Octocorallia): inferences on speciation processes [PDF]
, 2017 The study of the interplay between speciation and hybridization is of primary importance in evolutionary biology. Octocorals are ecologically important species whose shallow phylogenetic relationships often remain to be studied. In the Mediterranean Sea,

Diversity and Distributions, Volume 31, Issue 6, June 2025.ABSTRACT Aim Copepods are the key secondary producers in marine ecosystems, yet their in situ diet and symbionts remain underexplored due to technical challenges, limiting our understanding of their population dynamics and ecological functions. Using DNA metabarcoding, we jointly characterised the natural diet and symbionts of copepods across Chinese ...

The Evolution of Senses: My Research Journey into the Nervous System of Cnidaria [PDF]
, 2017 Our understanding of the evolutionary history of animals is improving, but knowledge of the ancient sensory systems that early animals used to interact with their environments is still largely unknown.

Monopodial and Sympodial Growth Modes in the Colonial Graptolithina (Hemichordata, Pterobranchia)
Evolution &Development, Volume 27, Issue 2, June 2025.ABSTRACT Two growth modes are recognized in colonial pterobranchs (Graptolithina): monopodial growth and sympodial growth. The earliest colonial Graptolithina likely developed through monopodial growth, a mode of colony formation well‐documented in the extant graptolite Rhabdopleura normani.

Acetylcholinesterase activity in Clytia hemisphaerica (Cnidaria) [PDF]
Chemico-Biological Interactions, 2008 Cholinesterase activity is known in representatives of all living organisms phyla but the origin of the cholinergic system as known in bilaterian animals is still undeciphered. In particular the implication of cholinesterases in the nervous system of non-bilaterian Metazoa is not well known.
