Redes de intercambio tempranas en lo Hoya Amazónica

open access: yesAmazonía Peruana, 1983
La única distribución diferencial de los recursos naturales entre la varzea y la tierra firme en la cuenca del Amazonas no puede explicar las extensas redes comerciales a lo largo del río principal que operaban en el momento de la conquista española de la zona.

Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

open access: yesNew Phytologist, EarlyView.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

Wood anatomical trait correlations with hydraulic efficiency and safety in an aseasonal wet tropical forest

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2701-2717, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Xylem anatomy underpins the capacity of trees to transport water while avoiding hydraulic failure, shaping species performance and resilience to climate change. However, the specific ways anatomical traits underpin hydraulic trade‐offs in tropical forests remain debated.

Turning Vulnerability Into Strength: How Independent Regulatory Agencies Enhance Accountability and Build Stakeholder Trust

open access: yesRegulation &Governance, Volume 20, Issue 3, Page 832-846, July 2026.
ABSTRACT Trustable environments are highly appreciated for regulatory performance, but difficult to emerge. A condition for making trust work is to accept vulnerability, and this holds both for stakeholders and agencies in public governance. Trust‐related vulnerability can be understood as a dynamic perception of potential harm derived from entering ...

Effects of selective harvest on antler size of white‐tailed deer in Texas, USA

open access: yesWildlife Monographs, Volume 222, Issue 1, June 2026.
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Simulating drying and human impacts on river networks to evaluate biological quality indices performance through the lens of metacommunity theory

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
This work constitutes a first step towards developing simulation‐based assessments that incorporate catchment drying patterns to support biomonitoring of drying river networks. Our approach can inform stakeholders when current methods are likely to fail and contribute to decision‐making on whether adapting current methods is possible or developing new ...

A response to ‘Quantifying phenotypic plasticity at multiple levels—A comment on Gómez et al.’

open access: yesFunctional Ecology, Volume 40, Issue 3, Page 560-562, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In this reply, we clarify several conceptual misunderstandings raised in response to our Perspective on quantifying phenotypic plasticity. We emphasize that our central argument concerns the rigorous estimation of the magnitude of plasticity, rather than its mere ...

Underrepresentation of bats in Africa's protected areas

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Biodiversity is severely threatened globally, with habitat loss and other human pressures accelerating species extinctions. Protected areas (PAs) are a critical conservation tool; however, their effectiveness in safeguarding many taxa, such as bats, remains unclear.
