Acoustic telemetry reveals high site fidelity of yellow‐phase American eels Anguilla rostrata in a large river

Journal of Fish Biology, EarlyView.
Abstract Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...

Age and growth of Mugil cephalus (Linnaeus, 1758) (Perciformes: Mugilidae) in Bonny Estuary [PDF]

, 2001
The age and growth of Mugil cephalus was investigated in Bonny Estuary, Nigeria, from January, 1995 to December, 1996. Length-weight relationships were isometric with length exponents of 2.84 (males), 2.90 (females) and 2.88 (overall).

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

The emergence of pathogens on fish in an impacted estuary and the role of non‐native piranhas in a potential bacterial infectious outbreak

Journal of Fish Biology, EarlyView.
Abstract As many tropical aquatic ecosystems worldwide, the Doce River estuary (DRE, southeastern Brazil) has increasingly faced multiple anthropogenic threats, including deforestation, mining, species introduction and water management. The 2015 collapse of the Fundão iron ore tailings dam severely changed water properties and increased heavy metal ...

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Climate change and El Niño Southern Oscillation influence on mixing regime and water quality in a deep tropical mountain lake

Limnology and Oceanography Letters
Climate change alters lake functioning, water quality, and aquatic biota; yet our understanding of this process is poor for deep tropical mountain lakes.

Dissecting the genetic basis of climatic adaptation in wild relatives (Malus baccata) for climate‐resilient apple breeding

Journal of Integrative Plant Biology, EarlyView.
This comprehensive map of genetic variation in wild apple (Malus baccata) and set of key genes associated with adaptation to temperature, precipitation, and soil properties establishes a foundation for breeding climate‐resilient apple cultivars and conserving the genetic resources of wild crop relatives.

Governing Transnational Commons: How International Treaties and Multi‐Stakeholder Organizations Shape Cooperation and Conflict

Journal of Management Studies, EarlyView.
Abstract When common‐pool resources such as freshwater, clean air, and fisheries span national borders, the collective action problems encountered are particularly severe. This study explores the role of polycentric governance systems in overcoming these pressing problems, which frequently underlie global grand challenges. Integrating political economy

Seasonal succession and niche differentiation in Skeletonema species driven by temperature and salinity in inner Tokyo Bay

Journal of Phycology, EarlyView.
Abstract The genus Skeletonema is a dominant diatom in coastal waters worldwide, frequently causing blooms, and it includes several cryptic species. To elucidate the occurrence patterns and niche differentiation among Skeletonema species in Tokyo Bay, Japan, sampling was conducted between June 2021 and February 2023.
