Plant‐Trait Syndromes and Environmental Filtering Drive Biomass Ecology in Resource‐Limited Forest Ecosystems

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Aboveground biomass (AGB) in Pakistan's forests is primarily driven by functional dominance, with soil fertility playing a secondary but significant role, while climate effects vary across forest types. Mixed forests support the highest biomass and show the strongest influence of dominant traits, whereas climate constraints are more evident in ...

Systematics of treefrogs of the Hypsiboas calcaratus and Hypsiboas fasciatus species complex (Anura, Hylidae) with the description of four new species

open access: yesZooKeys, 2014
We review the systematics of the Hypsiboas calcaratus species complex, a group of widely distributed Amazonian hylid frogs. A comprehensive analysis of genetic, morphological, and bioacoustic datasets uncovered the existence of eleven candidate species ...

Measuring Sand and Finer Suspended Sediment Concentration Profiles in Gravel Bed Rivers

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract Accurate measurement of sand and finer suspended sediment concentration profiles in rivers provides essential data for modeling suspended sediment transport. This study advances the application of an in situ laser diffraction instrument to measure the vertical distribution of suspended sediment concentration across multiple size fractions ...

Soil Diversity and Climate: An Overview of Profile Data and Acquisition With the WoSIS Global Legacy Dataset

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT Soil profiles are the primary field evidence from which pedogenesis, soil classification and land‐use effects are interpreted, yet their availability remains uneven across climates and land‐cover contexts. Here, we analyse the World Soil Information Service (WoSIS) 2023 snapshot together with Copernicus Global Land Cover 2015 and the global ...

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.

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

Similar looking sisters: A new sibling species in the Pristimantis danae group from the southwestern Amazon basin (Anura, Strabomantidae) [PDF]

open access: yesZoosystematics and Evolution
We describe a new frog species that is the sibling of Pristimantis reichlei. These two sister species inhabit the Amazonian lowlands and adjacent foothills of the Andes, from central Bolivia to central Peru.

Thinking of Melastomataceae: Revisiting Humboldt and Bonpland's Monographie des Melastomacées (1806–1823) from a historical perspective

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract During their voyage to the Americas (1799–1804), Alexander von Humboldt and Aimé Bonpland described and collected American flora, fauna, minerals and other objects. After returning to Europe, they published several works, including Monographie des Melastomacées, initiated by Bonpland to classify this complex botanical family.

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
