New species from the deep Pacific suggest that carnivorous sponges date back to the Early Jurassic [PDF]

open access: yes, 2008
Some deep-sea poecilosclerid sponges (Porifera) have developed a carnivorous feeding habit that is very surprising in sponges^1^. As shown by the typical morphology of their spicules, they most probably evolved from "normal sponges" under the ...

Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Porifera collection of the Italian National Antarctic Museum (MNA), with an updated checklist from Terra Nova Bay (Ross Sea)

open access: yesZooKeys, 2018
This new dataset presents occurrence data for Porifera collected in the Ross Sea, mainly in the Terra Nova Bay area, and curated at the Italian National Antarctic Museum (MNA, section of Genoa). Specimens were collected in 331 different sampling stations

Dietary adaptations along the northern limit of distribution: what does the smooth snake Coronella austriaca eat in Norway? Metabarcoding of stomach content and visual analysis of faeces

open access: yesWildlife Biology, EarlyView.
Understanding how species survive at their poleward limits of distribution is of interest in species conservation, particularly in light of global warming and predictions of shifting distributions of both predators and prey species. How species adapt to high latitudes and to future climate changes will be impacted both by direct interactions with the ...

Transposon-derived transcription factors across metazoans

open access: yesFrontiers in Cell and Developmental Biology, 2023
Transposable elements (TE) could serve as sources of new transcription factors (TFs) in plants and some other model species, but such evidence is lacking for most animal lineages. Here, we discovered multiple independent co-options of TEs to generate 788

Observations on North Dakota Sponges (Haplosclerina: Spongillidae) and Sisyrids (Neuroptera: Sisyridae) [PDF]

open access: yes, 2017
Factors influencing occurrence, distribution, and ecology of sponges and sisyrids are discussed, with emphasis on northeastern North Dakota. New state records for North Dakota sponges, Eunapius Jraguis Leidy and Ephydatia fluviatilis L. and the sisyrids,

Food web trophic control modulates tropical Atlantic reef ecosystems response to marine heat wave intensity and duration

open access: yesJournal of Animal Ecology, EarlyView.
In this study we showed that trophic control modulates the effects of marine heatwaves (MHWs) on species biomass dynamics in a tropical and pristine Atlantic reef ecosystem. Our study provides insights into how the strength of predator–prey interactions may generate different outcomes in face of intensified and prolonged MHWs. Abstract Marine heatwaves

Quantifying Bone Collagen Fingerprint Variation Between Species

open access: yesMolecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT Collagen is the most ubiquitous protein in the animal kingdom and one of the most abundant proteins on Earth. Despite having a relatively repetitive amino acid sequence motif that enables its triple helical structure, in type 1 collagen, that dominates skin and bone, there is enough variation for its increasing use for the biomolecular species
