From Natural to Human‐Dominated Seascapes: Habitat Loss for Guiana Dolphins Over Two Decades
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.ABSTRACT Changes in natural environments, such as coastal and marine zones, caused by human activities impact the quality of habitats and their inhabitants, ultimately jeopardising species conservation. As human activity is ever‐increasing, it is imperative to understand how multiple stressors, such as shipping, fisheries and pollution, affect marine ...

Hypotheses for the Adaptive Maintenance of Phenotypic Polymorphisms
Ecology and Evolution, Volume 16, Issue 5, May 2026.Phenotypic polymorphisms offer easily observable diversity ideal for empirical and theoretical exploration, but developing and comparing hypotheses for the adaptive maintenance of polymorphism can be a challenge. Here, we propose a framework categorizing polymorphisms based on (i) one of five distinct types of maintenance selection and (ii) the context

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge
People and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

People and Nature, Volume 8, Issue 5, Page 1066-1084, May 2026.Abstract Private land conservation (PLC) can contribute to sustainability by improving biodiversity and human well‐being but can also result in negative outcomes for people and nature if poorly designed. Informing PLC design to achieve objectives for joint biodiversity and well‐being is challenging because most evaluations assess ecological and social ...
