Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

Sedimentology, Volume 73, Issue 3, Page 593-619, April 2026.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

The influence of humidity, nutrients and light on the establishment of the epiphytic bromeliad Tillandsia guatemalensis in the highlands of Chiapas, Mexico

Revista de Biología Tropical, 1999
In the highlands of Chiapas, rapid habitat destruction and alteration threaten epiphytes. Presumably, forest transformation increases open and border-type vegetation, characterized by drier conditions than those prevailing deeper in the forest.

Comparative Study of Sulfated Polysaccharides From Ulva Lactuca Grown in Tunisia and Morocco: in Vitro Antioxidant Activity and in Vivo Anti‐Inflammatory and Anti‐Ulcer Effects

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT This study presents a comparative analysis of sulfated polysaccharides extracted from Ulva lactuca collected in Tunisia (PSUT) and Morocco (PSUM). FTIR confirmed the presence of sulfate groups, while GC‐MS identified diverse sugar components. Both polysaccharides showed strong antioxidant activity, with DPPH and ABTS radical scavenging rates ...

Multi‐Species Canopy Latrines in Costa Rican Cloud Forests: A Mammal Interactions Hub in a Single Tree Species

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We documented arboreal, multi‐species mammal latrines in montane cloud forests of Costa Rica by surveying 169 trees across 29 species. Latrines were found exclusively on Ficus tuerckheimii, with 11 occurrences across two mountain ranges and an additional observation in Honduras.

The Southernmost Known Population of the Monito Del Monte, Dromiciops gliroides

Ecology and Evolution, Volume 16, Issue 3, March 2026.
A range extension for a relict south American marsupial. ABSTRACT The monito del monte (genus Dromiciops) is a small arboreal marsupial endemic to the temperate rainforests of southern South America, and the sole extant representative of the order Microbiotheria. This lineage, considered a sister group of Australian marsupials, is of great evolutionary,

Phylogeny and Biogeography of Calanthe Shed New Light on Alpine Origin and Radiation History of Calanthe Alliance

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Using nrITS, plastome, and single‐copy SNP data, we resolved the phylogeny of the Calanthe alliance, which originated in the late Oligocene. Its diversification process followed a two‐step pattern: first the warmest Cenozoic interval and Himalayan uplift drove the formation of three major lineages, then sustained Miocene cooling shaped further ...

Health Benefits of Polysaccharides in Red Algae: A Comprehensive Review

Food Frontiers, Volume 7, Issue 2, March 2026.
Graphical abstract showing the health benefits of red algal polysaccharides. ABSTRACT Humans have long consumed red algae (especially by the Asian community), and their polysaccharide extracts (carrageenan, agar) are extensively used in the food industry as gel thickeners.

Epixylic microbial communities as key regulators of methane emissions from submerged wood in a tropical hydroelectric reservoir

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Tropical hydroelectric reservoirs are recognized hotspots for greenhouse gas emissions, yet the role of submerged forests in these emissions remains poorly understood. In this study, we investigated the contribution of standing dead trees and their associated epixylic biofilms to methane (CH4) and carbon dioxide (CO2) emissions in the ...
