Plant functional traits shape the provision of ecosystem services to Indigenous communities in western Amazonia

open access: yesPeople and Nature, Volume 7, Issue 12, Page 3313-3329, December 2025.
Abstract Context. Exploring how Indigenous People interact with plants through their functional traits allows us to understand the ecological bases of plant selection. Functional traits can help explain why certain plants are consistently chosen for specific purposes across diverse cultural contexts.

Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches

open access: yesNew Phytologist, Volume 248, Issue 1, Page 370-388, October 2025.
Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...

Impact of endometrial thickness on reproductive outcome in fresh and frozen–thawed embryo transfer: systematic review and meta‐analysis

open access: yesUltrasound in Obstetrics &Gynecology, Volume 66, Issue 3, Page 271-281, September 2025.
ABSTRACT Objective To evaluate the impact of endometrial thickness on the reproductive outcomes of embryo transfer (ET) treatments using both cut‐off‐based meta‐analysis and meta‐analysis of proportions. Methods This was a systematic review and meta‐analysis of comparative studies (randomized controlled trials, cohort studies, case–control studies) and

Physiological thermal niches, elevational ranges and thermal stress in dendrobatid frogs: An integrated approach

open access: yesJournal of Biogeography, Volume 51, Issue 10, Page 1880-1893, October 2024.
Abstract Aim We investigated the relationship between thermal physiology, elevational distribution and thermal stress among nine closely related dendrobatid frogs during their aquatic stage by employing an integrated approach, combining thermal physiology, environmental temperature modelling and predictive assessments of current and future exposure to ...

Using explainable machine learning methods to evaluate vulnerability and restoration potential of ecosystem state transitions

open access: yesConservation Biology, Volume 38, Issue 3, June 2024.
Abstract Ecosystem state transitions can be ecologically devastating or be a restoration success. State transitions are common within aquatic systems worldwide, especially considering human‐mediated changes to land use and water use. We created a transferable conceptual framework to enable multiscale assessments of state resilience and early warnings ...

MAPEAMENTO DE CONDUTIVIDADE HIDRÁULICA DOS AQUÍFEROS SUPERFICIAIS AO LONGO DA BR-319 NO TRECHO MANAUS – HUMAITÁ

open access: yesRevista Águas Subterrâneas, 2015
Na Amazônia predominam, em termos de área, os aquíferos rasos e livres. O nível de água destes aquíferos tem grande sensibilidade ao regime de precipitação, ao gradiente topográfico, à sazonalidade hidrográfica típica da região e, como em todo aquífero ...
