Integrating migratory connectivity data into the conservation of Australian sharks and rays

open access: yesConservation Biology, EarlyView.
Abstract Understanding migratory connectivity is important for conserving highly mobile marine species facing escalating threats. Establishing baseline information on migratory connectivity is necessary for identifying species and regions requiring transboundary cooperation for their conservation.

Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

open access: yesFisheries Management and Ecology, Volume 33, Issue 5, Page 963-976, October 2026.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).

When “Rescue” Means Exile: The Urgency of Science‐Based Protocols for Large Carnivore Interactions and Coexistence in the Neotropics

open access: yesAnimal Conservation, Volume 29, Issue 3, Page 233-234, June 2026.
Using the recent case of an Andean jaguar translocated hundreds of kilometers to a distinct savanna ecosystem in Colombia, we critique the prevalent “Reactive Removal” model often framed misleadingly as “rescue.” We contrast this approach, which disregards local adaptation, creates ecosystem mismatches, and blocks natural range recovery, with a needed “

Acclimatisation duration, not just release type, drives post‐release settlement in a large‐scale carnivore reintroduction programme

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our study highlights that when acclimatisation periods are too short, the substantial economic and logistical investment in soft‐release protocols may fail to deliver the expected conservation gains. Therefore, defining evidence‐based acclimatisation periods that are long enough to promote settlement, yet compatible with logistical constraints, may ...

Movement Strategies of Neotropical Nectarivorous Birds: Insights From High‐Andean Hummingbirds and Flowerpiercers

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Nectar is a highly variable, mostly unpredictable resource in tropical mountains. How do nectarivorous birds such as this male Great Sapphirewing cope? Fine‐scaled tracking of hummingbirds and flowerpiercers shows flexibility in daily movement strategies in the high Andes, possibly in response to fluctuating local conditions such as weather and ...

LPG Humidity Sensor With Carbonyl-Rich Graphene-Oxide Coating

open access: yesIEEE Access
In this study, we investigated the relative humidity (RH) sensor performance using long-period fiber gratings (LPG) covered with carbonyl-rich graphene oxide (CGO). The LPG was produced using the electric-arc-heating process on single-mode fiber (SMF-28).
