Modular co-option of cardiopharyngeal genes during non-embryonic myogenesis

EvoDevo, 2019
Background In chordates, cardiac and body muscles arise from different embryonic origins. In addition, myogenesis can be triggered in adult organisms, during asexual development or regeneration.

Near‐infrared confocal imaging reveals the spatial organisation of far‐red photosynthesis in Shark Bay microbial mats and Halomicronema sp.

Journal of Microscopy, EarlyView.
Abstract Far‐red light (FRL) cyanobacteria occupy spectrally filtered habitats where visible wavelengths are depleted but far‐red radiation persists. Shark Bay (Western Australia) stromatolitic microbial mats provide such a habitat, containing subsurface cyanobacterial communities in which chlorophyll d/f (Chl d/f)‐containing phototrophs coexist with ...

Figures and tables from Colonial ascidians strongly preyed upon, yet dominate the substrate in a subtropical fouling community

, 2019
Higher diversity and dominance at lower latitudes has been suggested for colonial species. We verified this pattern in species richness of ascidians, finding that higher colonial-to-solitary species ratios occur in the tropics and subtropics.

Kelp‐boulder transplants for habitat restoration

Restoration Ecology, EarlyView.
Abstract Introduction Degraded habitats present a major barrier to the survival and recovery of threatened marine species, particularly where structural or biogenic complexity has been lost, and natural regeneration ability is uncertain. Despite growing interest in habitat restoration, techniques rarely deliver rapid improvements at the necessary ...

Metabarcoding as a Tool in Characterizing Nordic Deep‐Sea and Arctic Benthic Ecosystems

Environmental DNA, Volume 8, Issue 6, November‐December 2026.
Multi‐marker sediment eDNA metabarcoding robustly discriminates benthic habitats across the Nordic Seas and Arctic Mid‐Ocean Ridge. Complementary 18S rDNA and COI performance enhances taxonomic resolution and supports standardized integration of metabarcoding into future deep‐sea biodiversity surveys.

Defensive Metabolites from Antarctic Invertebrates: Does Energetic Content Interfere with Feeding Repellence?

Marine Drugs, 2014
Many bioactive products from benthic invertebrates mediating ecological interactions have proved to reduce predation, but their mechanisms of action, and their molecular identities, are usually unknown.

Evidence for a Role of Hox2 in Atrial Siphon Fusion of the Ascidian Ciona

Development, Growth &Differentiation, Volume 68, Issue 8, October 2026.
ABSTRACT The hallmark of sessile adult ascidians is a vase‐like shape with a single oral and atrial siphon. Ciona, however, develops two atrial siphons after metamorphosis, which subsequently fuse into one. The mechanisms underlying this fusion are unknown. This study suggests that Hox2 controls this process.

Ascidians as models for studying invasion success [PDF]

, 2015
During the past three decades, coastal marine waters have become among the most invaded habitats globally. Ascidians are among the most notorious invaders in these ecosystems.

Nonindigenous Ascidians in Tropical Waters [PDF]

, 2002
Ascidians (invertebrate chordates) are abundant in many ports around the world. Most of them are nonindigenous species that tolerate wide fluctuations in temperature, salinity, and even pollution.
