Can the physical‐hydraulic properties of degraded soil be improved using polymers?

Soil Science Society of America Journal, Volume 89, Issue 6, November/December 2025.
Abstract For a degraded soil it is assumed that improvements in key physical‐hydraulic properties occur at an optimum superabsorbent polymer (SAP) application rate, following repeated wetting and drying cycles. A column experiment was carried out in a shade house (Ceará State, Brazil), following a completely randomized design, in a 6 × 4 factorial ...

The Light Bite: Red‐Nosed Cuxiu (Chiropotes albinasus, Primates) Exploit Differential Penetrability of Hard Fruit Husks When Selecting Dental Puncture Sites

Biotropica, Volume 57, Issue 6, November 2025.
Red‐nosed cuxiu are specialists in unripe seeds of hard‐husked fruits, which they access with massive jaw muscles and enlarged canines. But this costs energy and risks tooth breakage. The monkeys reduce both by biting at the softest spots on the fruit surface.

Plant Trait Matching Occurs in Facilitative Interactions Across Global Drylands

Global Ecology and Biogeography, Volume 34, Issue 11, November 2025.
ABSTRACT Aim Plant functional traits can influence interaction outcomes between nurse and target plants through a “functional trait match”, which occurs when the traits of nurse plants ameliorate their environment, and target plants possess traits that allow them to benefit from this ameliorated environment.
