Effectiveness of current and potential conservation actions for amphibians, birds and mammals

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
Our study demonstrates the power of combining differently‐sourced and compiled datasets to evaluate the likely effectiveness of ongoing conservation strategies and identify future needs. Our findings can inform species action plans and conservation spatial‐planning tools, helping to ensure that future conservation efforts are evidence‐based, have ...

How to remove the brain of Amazonian manatee (Trichechus inunguis) calves preserving the skull for morphological analysis [PDF]

Acta Amazonica
Although there are several studies on the skull of Amazonian manatees (Trichechus inunguis) to better understand the anatomy, physiology, and behavior of these animals, the analysis of the brain has been often neglected.

Enhanced Glycolysis‐Driven Histone H3K18 Lactylation Regulates Epileptogenesis by Modulating the E3 Ubiquitin Ligase COP1

Advanced Science, Volume 13, Issue 41, 22 July 2026.
Neuronal PKM2‐driven glycolysis generates excess lactate that triggers histone H3K18 lactylation (H3K18la), establishing a pathogenic metabolic‐epigenetic axis in epilepsy. Elevated H3K18la enriches the Cop1 promoter, transcriptionally upregulating the E3 ubiquitin ligase COP1, which subsequently drives proteasomal degradation of GABAARβ2 and impairs ...

Die Primärstruktur des Hämoglobins des Flu;-Manatis (Trichechus inunguis, Sirenia

, 1988
The hemoglobin of the Brazilian Manatee {Trichechus inunguis, Sirenia) consists of one component. We present the primary structures of the α- and β-chains which have been separated by chromatography on carboxy-methyl-cellulose Cm-Kresol52.

The small molecule simufilam dose‐dependently attenuates the worsening of seizures in a mouse model of tuberous sclerosis complex

Epilepsia, Volume 67, Issue 7, Page 3753-3765, July 2026.
Abstract Objective Novel epilepsy treatments for patients with tuberous sclerosis complex (TSC) and focal cortical dysplasia type II (FCDII) are urgently needed. In these patients, mutations in the mechanistic target of rapamycin (mTOR) pathway genes lead to mTOR hyperactivity and focal cortical malformations that frequently cause intractable epilepsy ...

The epizoic diatom Campylodiscus cf. clypeus (Bacillariophyta: Surirellaceae), a new symbiont of the Caribbean manatee in Mexico

Caldasia, 2018
Observations on the epizoic interaction between diatoms and marine mammals have been conducted mostly in cetaceans and are scarce in sirenians. By scraping the skin surface, the samples of biofilm were collected of a captive male Caribbean manatee in ...

Iterative evolution of sympatric seacow (Dugongidae, Sirenia) assemblages during the past ~26 million years. [PDF]

PLoS ONE, 2012
Extant sirenians show allopatric distributions throughout most of their range. However, their fossil record shows evidence of multispecies communities throughout most of the past ∼26 million years, in different oceanic basins.

Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.
