Receptor deorphanization in starfish reveals the evolution of relaxin signaling as a regulator of reproduction

BMC Biology
Background Relaxins are a family of peptides that regulate reproductive physiology in vertebrates. Evidence that this is an evolutionarily ancient role of relaxins has been provided by the discovery of two relaxin-like gonad-stimulating peptides (RGP1 ...

Lymphocyte Micronucleus Formation Is Driven by Inflammation‐Induced Oxidative DNA Damage in Oesophageal Cancer Development

International Journal of Cancer, EarlyView.
Chromosomal instability is a hallmark of cancer, but minimally invasive ways to detect systemic DNA damage and cancer risk remain limited. Here, using patient blood samples, the authors investigated lymphocyte micronuclei (MN) frequency as a potential marker of DNA damage across the progression from gastroesophageal reflux disease to Barrett's ...

Crown-of-thorns starfish [PDF]

Current Biology, 2013
Why ‘crown-of-thorns’? The crown-of-thorns starfish is nearly the largest species of starfish (Asteroidea). It may be 50 cm or more in diameter and can have more than 15 arms. Its ‘crown-of-thorns’ are the long sharp spines that cover its upper surface. What is more, the spines are coated with a saponin toxin, which causes irritation to puncture wounds

Breynia phuongiana (Phyllanthaceae), a new species from the Central Highlands of Vietnam

Nordic Journal of Botany, EarlyView.
A new species, Breynia phuongiana (Phyllanthaceae subgen. Sauropus), is described and illustrated from the Central Highlands of Vietnam. It is morphologically similar to B. beillei, B. bonii, and B. thorelii, but differs in having oblong‐elliptic leaves, sepals marked with reddish striations, an androphore exceeding 1 mm in length, and distinctly ...

Benthic megafauna and the functioning of macroalgal forests and urchin barrens

Oikos, EarlyView.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

Fast Injective Mesh Parameterization via Beltrami Coefficient Prolongation

Computer Graphics Forum, EarlyView.
Abstract We present a highly efficient and robust method for free boundary injective parameterization of disk‐like triangle meshes with low isometric distortion. Harmonic function–based approaches, grounded in a strong mathematical framework, are widely employed.
