Gap-free chromosome-level genomes of male and female spotted longbarbel catfish Hemibagrus guttatus
Scientific DataHemibagrus guttatus, also named as spotted longbarbel catfish, is an economical fish in China. However, their gender cannot be easily distinguished from their appearance, which largely impedes their artificial breeding.

The Bioeconomic Effects of Timber Harvesting on Recreational and Commercial Salmon and Steelhead Fishing: A Case Study of the Siuslaw National Forest [PDF]
The economic effects of changes in timber harvest levels on recreational and commercial salmon and steelhead fisheries are estimated by combining a series of simple watershed, habitat, population, and economic models.

A simple index for assessing cumulative human impacts on mountain lakes
Limnology and Oceanography: Methods, EarlyView.Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped

Life after Catch and Release [PDF]
, 2004 Since 1988 regulations have required U.S. longline fishermen to release all Atlantic white marlin, Tetrapturus albidus. By the late 1990’s, approximately 99% of Atlantic white marlin caught by U.S. recreational fishermen were released.

Marine litter can shift sea turtle nests toward the shoreline
Oikos, EarlyView.Marine litter is an emerging threat to sea turtle rookeries, yet its effects on nesting behaviour remain poorly understood. In this study, we investigated how macro‐litter accumulation on beaches influences the spatial distribution of loggerhead turtle Caretta caretta nests on Boa Vista Island, Cabo Verde.

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin
Oikos, EarlyView.Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

People and Nature, EarlyView.Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.
