Phylogeny of the Electric Rays of the Family Narcinidae (Gill, 1862): Systematic Review and Evidence of the Dispersal Routes to America

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The family Narcinidae has a cosmopolitan distribution; however, its systematic composition and phylogenetic position within Torpediniformes remain poorly understood. This study evaluates the evolutionary and biogeographic history of the family Narcinidae and investigates its distribution patterns using molecular systematics.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Will the Mediterranean Sea Be a Cul‐de‐Sac for Marine Gastropods Under Climate Change?

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Marine benthic gastropods remain understudied despite extensive historical records, limiting our understanding of their vulnerability to climate change. Using multi‐temporal species distribution models, we show that intermediate future climate conditions may trigger major habitat contractions for four key cowrie and frog‐shell species in the NE ...

Environmental Policy Without Implementation? A Review of Factors Contributing to Implementation Gaps in Low‐ and Middle‐Income Countries

Environmental Policy and Governance, Volume 36, Issue 3, Page 611-635, June 2026.
ABSTRACT The sound formation of robust environmental policies is increasingly important for low‐ and middle‐income countries (LMICs) to achieve their national objectives and international commitments.
