Integration of epigenetics into ecotoxicology: insights and fundamental research needs

open access: yesBiological Reviews, Volume 101, Issue 2, Page 826-847, April 2026.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

Fish and macroinvertebrates in lowland drainage canals with and without grass carp [PDF]

open access: yes, 2006
Diploid grass carp (Ctenopharyngodon idella L.) were introduced to a lowland Waikato drainage canal at an initial density of 40-80 kg ha -1(83-167 fish ha -1) to control aquatic macrophytes and improve water flow.

Systemic Sonic Hedgehog Signaling Links Intestinal Nutrient Sensing With Sex‐Specific Type 2 Diabetes Progression

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Here, Systemic Sonic Hedgehog (Shh) emerges as a sex‐specific metabolic signal and potential biomarker. Across two large cohorts, Shh rose selectively in females with type 2 diabetes, with a sharp pre‐diagnostic increase in about one‐quarter of cases, indicating value for early risk stratification.

The Historical and Overlooked Collapse of Medicinal Leeches in Spain

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT Leeches in genus Hirudo have been used in medicine since ancient times, but increased exploitation during the 19th century led to the depletion of several populations in Europe. A compilation of Hirudo records in Spain (H. troctina Johnson, 1816 and H. verbana Carena, 1820) show that the genus was more commonly mentioned and widely distributed

The endocannabinoid system regulates both ependymoglial and neuronal cell responses to a tail amputation in the axolotl

open access: yesDevelopmental Dynamics, Volume 255, Issue 3, Page 321-339, March 2026.
Abstract Background The endocannabinoid system is a neuromodulatory system implicated in cellular processes during both development and regeneration. The Mexican axolotl, one of only a few vertebrates capable of central nervous system regeneration, was used to examine the role of the endocannabinoid system in the regeneration of the tail and spinal ...

Niche Partitioning Promotes Coexistence: Habitat Suitability and Spatial Overlap of Three Sympatric Ungulates in a Subtropical Mountain Reserve

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study assessed the habitat suitability and spatial niche differentiation of three sympatric ungulates—Black muntjac, Reeves's muntjac, and Wild boar—in the Tongbo Mountain National Nature Reserve, China. Using MaxEnt modeling and niche overlap analysis, we found distinct habitat preferences and hierarchical niche segregation that facilitate ...

Sympatric Distribution of Giant Pandas and Red Pandas in Sichuan Province: Habitat Overlap Patterns and Implications for the Giant Panda's Umbrella Effect

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study quantified habitat overlap between giant and red pandas in their sympatric range using the MaxEnt model, confirming a significant umbrella effect for the red panda. However, conservation gaps exist, as red pandas are more sensitive to high‐altitude areas (> 3200 m) and anthropogenic disturbance, requiring refined management strategies for ...
