Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, Volume 55, Issue 5, Page 681-692, September 2026.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Frozen and Scorched: Genomic Signatures of Adaptive Divergence and Hibernation in the Living Fossil Dromiciops

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We evaluated adaptation to torpor and hibernation in the genus Dromiciops by comparing it with both torpid and non‐torpid marsupials, and investigated divergent selection signals between its two species. For the ancestral node, we identified positive selection in the genes PFKFB2, LAMP3, OTX1, and RAPSN, alongside an enrichment of pathways potentially ...

Drivers of Stopover Distribution Across Two Autumn Migration Routes of a Long‐Distance Afro‐Palearctic Migrant, the Common Cuckoo (Cuculus canorus)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We model autumn stopover distribution of UK common cuckoos across two migration routes, revealing distinct environmental drivers and key geographic hotspots. Iberian mountain systems and the Po watershed emerge as critical stopover regions, with climate, elevation, habitat heterogeneity, and hunting risk shaping route‐specific patterns.

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, Volume 41, Issue 6, Page 873-887, August 2026.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Experimental, Genomic, and Structural Evidence Supporting Putative PET‐Hydrolases in Thermophilic Bacteria Isolated From Hot Springs in Cajamarca, Peru

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Integrated microbiological, genomic, and structural analyses of bacteria isolated from a Peruvian geothermal system reveal enzymatic potential for the transformation of polyesters such as PET. This study links experimental evidence with genomic determinants and in silico analyses that support the thermophilic bacteria biodegradation capacity.

Multitrophic alpha and beta diversity of lake plankton across Canada

Oikos, Volume 2026, Issue 8, August 2026.
Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...

Water and Gas Exchange Responses of Five Related Blueberry Species (Ericaceae spp.) to the Dry Season in the High‐Andean Forest of the Colombian Eastern Cordillera

Plant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Vaccinium, Cavendishia, and Macleania are typical genera of blueberries from the Ericaceae belt, a narrow ecosystem that connects the high Andean forest and páramo, where fragmentation makes the species more vulnerable to climate change. To answer the question of whether five related blueberry species could physiologically behave similarly in ...

Petrogenesis and Tectonic Evolution of Cenozoic Magmatism in the Southernmost Northern Andes: Insights From Zircon Petrochronology

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study integrates new zircon U–Pb ages, zircon εHf(t)–δ18O isotopic data, and whole‐rock geochemistry to refine the temporal and spatial framework of magmatism in the southern Northern Andes (SNA) from ∼65 to 6 Ma. The San Lucas, Catamayo, Portachuela, and Gonzanamá batholiths and magmatic suites, along with Late Miocene plutons, display ...
