Individual Trees Respond to 40 Years of Climate Change Through Leaf Functional Trait Acclimation

open access: yesGlobal Change Biology, Volume 32, Issue 7, July 2026.
We measured leaf traits from historic and contemporary herbarium specimens collected from the same individual trees in the southern Peruvian Amazon and compared trait changes to local changes in climate which included increasing temperature, decreasing precipitation, and increasing [CO2]. We found significant decreases in leaf mass per area (LMA), leaf

Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

open access: yesGrassland Science, Volume 72, Issue 3, Page 163-174, July 2026.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

Dispersal and in Situ Speciation as Contributors to Plant Diversity in the Chocó Region: Insights From Inga Mill. (Leguminosae)

open access: yesJournal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim To investigate the historical processes underlying the assembly of the flora of the Chocó region, with a focus on the relative contributions of dispersal and in situ speciation. Using Inga (Leguminosae) as a model lineage, we evaluate the origin and diversification of species present in the Chocó.

Distribution of Tropical Vegetation From the Pliocene to the Anthropocene

open access: yesJournal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim The tropics harbour most of Earth's terrestrial biodiversity. This biodiversity has been influenced by cycles of climatic stability and instability over millions of years and may be affected by abrupt changes in the near future. We reconstructed the geographic distribution of the major tropical vegetation types (deserts, semi‐arid ...

Environmental Drivers and Biogeographic Patterns of South American Endemic Ants: Insights From IUCN Red List Assessments

open access: yesJournal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim South American endemic ants play a central role in terrestrial ecosystems but remain poorly integrated into continent‐scale conservation assessments. Their distributions and community composition have likely been shaped by past climatic dynamics and persistent refugia.

Time‐calibrated relationships of a rare cave catfish (Trichomycterus rubbioli): Shedding light on troglobitic lifestyle origin in the Brazilian caatinga

open access: yesJournal of Fish Biology, Volume 109, Issue 1, Page 362-370, July 2026.
Abstract Catfishes of the subfamily Trichomycterinae comprise the most diverse fish group with species adapted to live in Neotropical caves, but past evolutionary scenarios that have driven the origin of these troglobitic species remain unknown. We herein investigate the phylogenetic position of the cave‐restricted Trichomycterus rubbioli, endemic to ...
