Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.

SharkTrack: An accurate, generalisable software for streamlining shark and ray underwater video analysis

Ecological Informatics
Elasmobranchs (sharks and rays) represent a critical component of marine ecosystems. However, they are experiencing global population declines, making effective monitoring essential for their management.

Swimming Under the Radar: Trout‐Free Kōaro Populations in Aotearoa Lakes and Tarns Are Rare, Understudied, and Disappearing

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Over the last 150 years, most large, easily accessible lakes and tarns in Aotearoa (New Zealand) have experienced trout introductions or incursions, leaving few salmonid‐free reference lakes. Using database information and field surveys, we characterized lake, pond/tarn, and wetland systems found throughout Aotearoa that support populations of kōaro ...

How Speculation Became Accepted Truth: Evidence that Aotearoa New Zealand Freshwater Eels Do Not Seem to Spawn “Near Tonga” or “East of Samoa”

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
For several decades, the assumption that Aotearoa New Zealand freshwater eels spawn near Tonga (for longfin, Anguilla dieffenbachii) or east of Samoa (for shortfin, A. australis) has been widely repeated across scientific literature, governmental reports, public resources and community narratives, despite limited direct evidence.

A shift in the trade? An investigation of the eel trade reveals a likely species switch

Conservation Science and Practice
Anguillid eels have seen precipitous declines in their population sizes. Because of these declines, a number are currently designated as Endangered, Critically Endangered, or are listed on Convention on International Trade in Endangered Species Appendix ...

Confidence intervals for extinction risk: Validating population viability analysis with limited data

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1837-1850, June 2026.
Abstract The assessment of extinction risk remains a key component of IUCN and CITES evaluations. However, it has been argued that, under realistic data limitations, confidence intervals (CIs) for extinction probability often span the entire 0–1 range, rendering such assessments meaningless.

A new acoustic telemetry tag that identifies carrier mortality by monitoring activity level

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1735-1742, June 2026.
Abstract We present a new acoustic telemetry tag capable of detecting whether its carrier stops moving for long enough to presume the organism has died, and of reporting the time elapsed since movement ceased. The tag uses existing environmental sensor technology together with an algorithm with user‐specifiable thresholds, and importantly, can separate

In Search of the Lost Brown Trout (Salmo trutta Complex) Using DNA of Ancient and Modern Samples From the Southern Italian Peninsula

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT The current diversity and distribution of species and populations have been shaped by the major climatic oscillations during the Quaternary. The brown trout (Salmo trutta) is a striking example of the strong effect of past climate changes on the evolutionary history of species, in fact, the alternation of glacial/interglacial cycles has led to
