Heat limits scale with metabolism in ectothermic animals

open access: yesJournal 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.

Metabarcoding Unveils the Diversity and Dynamics of In Situ Diet and Symbionts Associated With Copepods in Chinese Coastal Waters

open access: yesDiversity 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 ...

Monopodial and Sympodial Growth Modes in the Colonial Graptolithina (Hemichordata, Pterobranchia)

open access: yesEvolution &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.

The Function of Surface Sclerites in Gorgonians (Coelenterata, Octocorallia)

open access: yesThe Biological Bulletin, 1991
Branches of a variety of species of gorgonians representing the common sclerite types were fixed in flexed (bent) positions and examined by scanning electron microscopy. To determine changes in position of sclerites associated with extension and compression, appropriate measures of sclerite density and angle were taken.

Nutritional potentials inZoanthus sociathus (Coelenterata, Anthozoa) [PDF]

open access: yesHelgoländer Wissenschaftliche Meeresuntersuchungen, 1974
1. The tropical coral reef-dwelling coelenterateZoanthus sociatus (Ellis) lives in mutualistic symbiosis with dinoflagellates of the genusGymnodinium. These algae are intracellular. 2. Analysis of the photosynthetic contribution of these endosymbionts shows a direct transfer of photosynthate from algae to animal and utilization of such substances by ...

Quantitative composition and distribution of the macrobenthic invertebrate fauna of the Continental Shelf ecosystems of the Northeastern United States [PDF]

open access: yes, 1998
From the mid-1950's to the mid-1960's a series of quantitative surveys of the macrobenthic invertebrate fauna were conducted in the offshore New England region (Maine to Long Island, New York).

Redescription of Acrophytum claviger (Coelenterata: Octocorallia)

open access: yesThe Beagle : Records of the Museums and Art Galleries of the Northern Territory, 1985
Acrophytum claviger Hickson, a little known soft coral from South African waters, is redescribed from one of Hickson's original specimens. The specimen is designated as a paralectotype. Photographs and sclerite drawings supplement Hickson's sparsely illustrated paper, as do histological data from an additional specimen containing an unusual ...
