Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Weak Nuclear Divergence Despite Pronounced Mitochondrial Divergence Within a Widespread Desert‐Inhabiting Palearctic Lark (Aves: Alaudidae)

open access: yesZoologica Scripta, EarlyView.
ABSTRACT The Bar‐tailed Lark Ammomanes cinctura is a polytypic bird species with a wide distribution. One of its three subspecies, A. c. arenicolor, has previously been found to show deep mitochondrial divergence between its geographically most distant populations, from Morocco and Saudi Arabia, respectively.

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,

Telecological Collapse: The Inevitability of Climate Breakdown in the Transmedial Podcast Drama Forest 404

open access: yesFuture Humanities, Volume 4, Issue 1, May 2026.
ABSTRACT This paper presents a close‐hearing analysis of Forest 404, a transmedial audio drama that was released to BBC Sounds in 2019. Despite the drama's eco‐dystopian critique of teleological ‘progress’ narratives (that enable and perpetuate the destruction of the natural world), I argue that the series ultimately propagates a sense of inevitability
