An Approximate Time‐Domain Solution for Recharge Propagation Through Thick Unsaturated Zones

Hydrological Processes, Volume 40, Issue 6, June 2026.
This study presents a time‐domain analytical solution for modelling groundwater recharge through thick unsaturated zones, applied to the Urucuia aquifer in Brazil. The model was calibrated using observed well data, capturing the attenuation of seasonal groundwater level fluctuations with depth.

Research Trends on Trace Element Contamination in Brazilian Urban Lentic Ecosystems: Environmental and Policy Drivers

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Lentic ecosystems are vulnerable to contamination by trace elements, which can accumulate and pose risks to aquatic life and human health. In a large, developing country such as Brazil, marked by vast geographic, environmental, and socioeconomic diversity, it is crucial to understand how these factors shape research on this group of ...

Scheffrahnitermes ubuntu (Isoptera: Apicotermitinae), Description of a New Termite Using a Collaborative Approach to Address the Wallacean Shortfall

New Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
The study of Neotropical Apicotermitinae remains challenging due to the large number of undescribed taxa (Linnean shortfall) as well as the scarcity of distributional data (Wallacean shortfall). Despite recent efforts to reduce the first one, the second remains an even more significant challenge.

Weed Management Influences the Accumulation of Organic Matter in the Soil and Productivity in Coffee Farming

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.
The management of weeds can influence organic matter (OM) and organic carbon (OC) levels, impacting the productivity and sustainability of coffee plantations. This study aimed to evaluate OM and OC levels in coffee soils under different weed management practices and their influence on coffee tree physiology and productivity. The experiment featured six

Evolutionary and environmental drivers of dry-season deciduousness in a legume genus. [PDF]

New Phytol
Summary Leaf deciduousness is a key drought‐avoidance strategy in tropical flora, reducing water loss during seasonal dry periods. While winter‐deciduousness in temperate regions is well‐understood, the evolutionary and environmental drivers of dry‐season deciduousness remain poorly explored.

The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

Oikos, Volume 2026, Issue 6, June 2026.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.
