Trends and Challenges in Water Governance Systematic Review and Bibliographic Study of Scientific Publications (2018–2025)

World Water Policy, Volume 12, Issue 2, May 2026.
ABSTRACT Water governance has emerged as a critical analytical framework for addressing the complexity of socioecological water systems in contexts of increasing climate vulnerability and anthropogenic pressure. This study presents a systematic review and bibliometric analysis of 50 scientific articles indexed on water governance published between 2018

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

Ecological Entomology, Volume 51, Issue 2, Page 221-234, April 2026.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Assessing contributions of deterministic versus stochastic processes to local species assembly: A field experiment with annual plant‐dominated communities in gypsum systems

Journal of Ecology, Volume 114, Issue 3, March 2026.
In this study, we experimentally show that stochasticity can play prominent roles in driving local species assembly in annual plant‐dominated communities of semiarid gypsum ecosystems. Drylands are traditionally viewed as restrictive environments that impose strong deterministic filtering effects, but neutral events can also contribute decisively to ...

“Does a Respiratory Virus Have an Ecological Niche, and If So, Can It Be Mapped?” Yes and Yes

Tropical Medicine and Infectious Disease, 2023
Although the utility of Ecological Niche Models (ENM) and Species Distribution Models (SDM) has been demonstrated in many ecological applications, their suitability for modelling epidemics or pandemics, such as SARS-Cov-2, has been questioned.

Nocturnal Gardeners: Dispersal of Large Seeds by Tent‐Roosting Bats in the Lacandon Rainforest, Mexico

Biotropica, Volume 58, Issue 2, March 2026.
Tent‐roosting bats in the Lacandon Forest, Mexico, play a previously undocumented role in dispersing large seeds (> 5 mm) from mature forest species with important ecological and human uses. Sampling 21 feeding tents across two protected areas yielded 2137 seeds from 54 species, with seed deposition rates significantly higher under bat tents than in ...
