A new endemic pearl cichlid of the ‘Geophagus’ brasiliensis (Cichliformes: Cichlidae) species group from the Piranga River, upper Doce River basin, southeastern Brazil

Journal of Fish Biology, EarlyView.
Abstract A new species of pearl cichlid of the ‘Geophagus’ brasiliensis species group, endemic to the Piranga River, a major tributary of the upper Doce River basin in the state of Minas Gerais, southeastern Brazil, is herein described. The new species is delimited using an integrative approach, with molecular‐based species delimitation methods coupled

Rapid increase in abundance and distribution of invasive pink salmon (Oncorhynchus gorbuscha) within a diverse, large Barents Sea catchment

Journal of Fish Biology, EarlyView.
Abstract Pink salmon originate from the North Pacific area but were introduced into northwest Russia from the late 1950s onwards. Since 2017, the alien species has increased dramatically in abundance and rapidly invaded adjacent areas of the North Atlantic region.

Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon (Salmo salar L.)

Journal of Fish Diseases, EarlyView.
ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a

Impact of noise on the behaviour and biochemical parameters of the crayfish Cherax quadricarinatus and Cherax destructor

Journal of Zoology, EarlyView.
The aim of this study was to evaluate the effect of acoustic stimulus on the behavioural and biochemical responses of two species of crayfish, Cherax destructor and Cherax quadricarinatus. Our results showed that exposure to noise significantly affects in both species motility parameters, agonistic interactions and acoustic signals emitted. In terms of

Join the Green and Sustainable Team: Magnesium Oxide Nanoparticles Boost Broad‐Spectrum Viral Resistance in Solanaceae Plants

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant viruses are so harmful to crops. It is an urgent need to develop modern, environment‐friendly, and sustainable plant viral epidemic‐management strategies that are safe for both human health and the environment. The field of nanotechnology is gaining increased interest in plant science.

Distinct developmental dynamics of opposing persistent currents shape motoneuron firing during motor maturation of zebrafish

The Journal of Physiology, EarlyView.
Abstract figure legend During the first few days of development, zebrafish acquire the ability to produce increasingly refined movements that rely progressively less on the activity of primary motoneurons. At the same time, primary motoneurons undergo functional maturation, becoming increasingly capable of repetitive firing.

Potential Trophic Competition Between the European Perch Perca fluviatilis and Pikeperch Sander lucioperca

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT The European perch Perca fluviatilis and pikeperch Sander lucioperca can co‐occur, potentially competing for food resources. However, few studies have addressed the potential feeding competition between these species. We used carbon and nitrogen stable isotope analysis to assess the potential trophic competition between these species in two ...
