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

The underappreciated roles of fog and dew on vegetation and biocrusts

open access: yesNew Phytologist, Volume 251, Issue 1, Page 46-63, July 2026.
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

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.

Physical land suitability assessment for sugarcane (Saccharum officinarum L.) production in Western Ethiopia

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Land is a non‐renewable resource that has a finite quantity, and efficient use of this resource is imperative for food security, development, and adaptation to climatic change. In this regard, land suitability analysis is a fundamental decision‐support system that ensures the allocation of this resource for an optimal production agenda while ...
