Revisiting the taxonomy and nomenclature of Phyla, a small genus of Verbenaceae

open access: yesNordic Journal of Botany, Volume 2025, Issue 12, December 2025.
Phyla is unique within Verbenaceae due to the presence of malpighiaceous hairs. Its taxonomy has long been marked by difficulties in defining species boundaries. The most recent revision of the genus recognized five species and three varieties. In this study, however, we recognize only two species and no varieties: P.

Integrating Long‐Term InSAR Monitoring Into Local Groundwater Management: Insights From the Hollywood Basin, California

open access: yesWater Resources Research, Volume 61, Issue 11, November 2025.
Abstract We demonstrate the effectiveness of long‐term continuous interferometric Synthetic Aperture Radar (InSAR) monitoring for local resource management. Sustainable yield is a key concept in groundwater management to ensure sustainable, low‐impact groundwater extraction.

Leaf Size and Shape Interact to Control Flammability: An Experiment With Artificial Leaves Cut From the Large‐Leaved Species Sapranthus palanga

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
We evaluated the flammability of leaves based on their shape and size. Rectangular and triangular shapes showed high flammability that did not vary with size, while circular shapes had minimal flammability, but it varied with size. These findings indicate that leaf shape and size impact flammability.

Habitat Protection Alone Is Insufficient: Costa Rican Parrots Thrive in Altered Landscapes but Remain Vulnerable to Poaching

open access: yesDiversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Human population growth and resource overexploitation have induced major changes in global biodiversity. Costa Rica, with 26% of its land area protected, is often cited as a model of environmental conservation. However, conservation efforts have largely focused on habitat preservation, while overharvesting remains an unquantified factor in
