The most threatened plants receive the least scientific attention

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

Threatened status of neglected and underutilised Jatropha (Euphorbiaceae) species endemic to Mexico

open access: yesRevista Mexicana de Biodiversidad, 2019
Jatropha curcas is the best known species from the genus, an oilseed crop used for biodiesel production. It deserves attention as more species show similar oil content, phytochemical properties, or as a genetic resource in J.

Chemical diversity and phylogenetic insights into Hawaiian ʻākia (Wikstroemia) species used in traditional fishing practices

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Traditional fishing with plant‐based piscicides is a global practice in decline, facing increasing restrictions. We investigated the chemical diversity of endemic Wikstroemia species historically used to stun or poison fish in Hawaiʻi. Using 1‐H‐NMR, principal component analysis, targeted HPLC, and target‐capture sequencing, we characterized compounds ...

Conservation gap analysis for wild grapevines (Vitis L.) of the Americas

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Wild grapevines (Vitis L.) native to the Americas are ecologically and culturally important plants that are also critical to the global cultivated grape industry as sources of traits for crop innovation, but many of these species are poorly documented and insufficiently conserved.

Building a genomic and herbarium biorepository for medicinal plants of the Western Ghats

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Medicinal plants support healthcare for millions of people and sustain livelihoods, yet many threatened species lack secure long‐term genetic protection. This study establishes a genomic and herbarium biorepository for medicinal plants of the Western Ghats, a global biodiversity hotspot facing intense human pressure.

Evaluating land–sea linkages using land cover change and coral reef monitoring data: A case study from northeastern Puerto Rico

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Land cover change that leads to increased nutrient and sediment runoff is an important driver of change in coral reef ecosystems. In this study, we combined satellite remote sensing and field monitoring to assess concomitant changes in watershed land cover and coral cover in northeastern Puerto Rico in 2000–2015.

Red List of birds in Slovakia: update 2013–2023 [PDF]

open access: yesTichodroma
The national Red List was updated for the period 2013–2023, based on the improved knowledge and the change in the conservation status of some rare bird species. IUCN categories and criteria according to version 3.1 were used and recommendations for their

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

A Tracking‐By‐Detection Framework to Automatically Count Rare and Elusive Megafauna in Aerial Video Surveys

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Monitoring programs of vulnerable megafauna increasingly rely on aerial surveys from drones or planes fitted with cameras. However, automated methods are still lacking to accurately count individuals across entire surveys. Here, we leverage a tracking‐by‐detection framework to not only detect individuals but also link the resulting detections across ...

Threat categories of Vatica mangachapoi should be reassessed

open access: yesFrontiers in Forests and Global Change
IntroductionAsian tropical rainforests have the highest rates of degradation in the world. Consequently, a large decline in Chinese Vatica mangachapoi (a keystone species) had led to its listing in the category of “vulnerable” species by IUCN.
