Phylogeography of western Mediterranean Cymbalaria (Plantaginaceae) reveals two independent long-distance dispersals and entails new taxonomic circumscriptions

open access: yesScientific Reports, 2018
The Balearic Islands, Corsica and Sardinia (BCS) constitute biodiversity hotspots in the western Mediterranean Basin. Oligocene connections and long distance dispersal events have been suggested to cause presence of BCS shared endemic species.

Brazil seed transfer zones: Supporting seed sourcing for climate‐resilient ecosystem restoration

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Brazil has tens of millions of hectares of degraded land that must be restored to meet national and global biodiversity and climate goals. Sowing genetically diverse native seeds is key to restoring degraded lands to climate‐resilient landscapes, but we still lack guidance on how to effectively match seed sources to restoration sites across broad ...

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

frontiermetrics: An R Package for Characterizing Deforestation Frontiers

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Deforestation frontiers are major drivers of biodiversity loss, carbon emissions, and ecosystem degradation, yet our understanding of how deforestation progresses in these frontiers is limited. We present frontiermetrics, an R package to quantify a range of metrics describing the speed, severity, and spatio‐temporal patterns of forest loss. The package

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

open access: yesWildlife Monographs, EarlyView.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low
