Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, Volume 2026, Issue 8, August 2026.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

The proteotranscriptomic characterization of venom in the white seafan Eunicella singularis elucidates the evolution of Octocorallia arsenal

Open Biology
All the members of the phylum Cnidaria are characterized by the production of venom in specialized structures, the nematocysts. Venom of jellyfish (Medusozoa) and sea anemones (Anthozoa) has been investigated since the 1970s, revealing a remarkable ...

Multigene Family of Pore-Forming Toxins from Sea Anemone Heteractis crispa

Marine Drugs, 2018
Sea anemones produce pore-forming toxins, actinoporins, which are interesting as tools for cytoplasmic membranes study, as well as being potential therapeutic agents for cancer therapy.

Variable species establishment in response to microhabitat indicates different likelihoods of climate‐driven range shifts

Ecography, Volume 2026, Issue 8, August 2026.
Climate change is causing geographic range shifts globally, and understanding the factors that influence species' range expansions is crucial for predicting future biodiversity changes. A common, yet untested, assumption in forecasting approaches is that species will shift beyond current range edges into new habitats as they become macroclimatically ...

Lagged climate‐driven range shifts at species' leading, but not trailing, range edges revealed by multispecies seed addition experiment

Ecography, Volume 2026, Issue 8, August 2026.
Climate change is causing many species' ranges to shift upslope to higher elevations as species track their climatic requirements. However, many species have not shifted in pace with recent warming (i.e. ‘range stasis'), possibly due to demographic lags or microclimatic buffering.

Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, Volume 251, Issue 4, Page 1755-1773, August 2026.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Dart formation in nematocysts of the sea anemone Metridium senile (Linnaeus, 1761) (Cnidaria: Anthozoa)

Scientia Marina, 2010
In examining large acontia b-mastigophore and p-amastigophore nematocysts of the sea anemone Metridium senile (Linnaeus, 1761) darts were observed by interference-contrast light microscopy (LM) and scanning electron microscopy (SEM). The darts consist of

Proteotransciptomics of the Most Popular Host Sea Anemone Entacmaea quadricolor Reveals Not All Toxin Genes Expressed by Tentacles Are Recruited into Its Venom Arsenal

Toxins
While the unique symbiotic relationship between anemonefishes and sea anemones is iconic, it is still not fully understood how anemonefishes can withstand and thrive within the venomous environment of their host sea anemone.

Partial sequence and toxic effects of granulitoxin, a neurotoxic peptide from the sea anemone Bunodosoma granulifera

Brazilian Journal of Medical and Biological Research, 1998
A neurotoxic peptide, granulitoxin (GRX), was isolated from the sea anemone Bunodosoma granulifera. The N-terminal amino acid sequence of GRX is AKTGILDSDGPTVAGNSLSGT and its molecular mass is 4958 Da by electrospray mass spectrometry.

Anemonefish use sialic acid metabolism as Trojan horse to avoid giant sea anemone stinging

BMC Biology
Background Anemonefish association with sea anemones is a prime example of mutualistic symbiosis. These fish live inside the sea anemone, benefitting from the protection of its toxic nematocysts, and in return, protect the anemone from its own predators.
