Hypotheses for the Adaptive Maintenance of Phenotypic Polymorphisms

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Phenotypic polymorphisms offer easily observable diversity ideal for empirical and theoretical exploration, but developing and comparing hypotheses for the adaptive maintenance of polymorphism can be a challenge. Here, we propose a framework categorizing polymorphisms based on (i) one of five distinct types of maintenance selection and (ii) the context

Canopy Definitions Shape Canopy Space Filling–Productivity Relationships: Evidence From Terrestrial Laser Scanning

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The spatial arrangement of trees and their branches within the canopy is crucial for light interception, often resulting in a positive relationship between canopy space filling and stand productivity. To date, there is no universal definition of canopy space.

Soft Tissue Sarcoma Burden and Research Productivity: Global Patterns and Disparities, 1990–2021

Health Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background Soft tissue sarcoma (STS) is a rare and diverse type of cancer, with a disproportionate incidence and limited global epidemiological studies. This study aims to analyze the long‐term trends and epidemiological features of the global burden of STS from 1990 to 2021 and to reveal the global research productivity on STS.

Stemflows and Preferential Flows: A Historical Review and Challenges for the Future

Hydrological Processes, Volume 40, Issue 5, May 2026.
Possible implementation of stemflow in the MIPS model where all water in the system is represented as particles in pathways of specified velocity. Stemflow (green particles) can be treated as a localised input with probabilities of entering higher velocity pathways than throughfall, depending on the input rates.
