Edge effect influences the ecological strategies of plant communities in tropical forest fragments

open access: yesPlant Biology, Volume 28, Issue 2, Page 509-519, March 2026.
The edge effect in Eastern Amazonia influences ecological strategies of plant communities, with forest edges promoting traits linked to hydraulic efficiency, while interior species exhibiting diverse ecological strategies. Abstract The continuous fragmentation of tropical forests is a major threat to biodiversity and ecosystem functioning. This process

Historical Climate and Biome Association Drove Phylogeographic Patterns in the Dwarf Swamp Frog (Anura: Leptodactylidae)

open access: yesZoologica Scripta, Volume 55, Issue 2, Page 220-231, March 2026.
ABSTRACT South America, a region with high biodiversity, has been profoundly shaped by geological events during the Miocene and Pliocene, as well as by climatic changes in the Pleistocene, leading to complex phylogeographic patterns. The diverse biomes and the biotic exchanges between them, particularly between the Amazon and the Cerrado, have ...

Silesaurid (Archosauria: Dinosauriformes) remains from the base of the Dockum Group (Late Triassic: Otischalkian) of Texas provide new insights to the North American record of dinosauriforms

open access: yesThe Anatomical Record, Volume 309, Issue 2, Page 293-313, February 2026.
Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...

Simulating climate change scenarios established by the Intergovernmental Panel on Climate Change in aquatic mesocosms

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 2, February 2026.
Abstract Climate change poses a major threat to ecosystems worldwide, with temperature changes being a key driver of ecological disruption in aquatic environments due to the limited ability of many aquatic species to relocate in response. Despite advances in aquatic experimental approaches to temperature control, most studies rely on simplified warming
