In Silico and Fluorescence In Situ Hybridization Mapping Reveals Collinearity between the Pennisetum squamulatum Apomixis Carrier-Chromosome and Chromosome 2 of Sorghum and Foxtail Millet. [PDF]

open access: yesPLoS ONE, 2016
Apomixis, or clonal propagation through seed, is a trait identified within multiple species of the grass family (Poaceae). The genetic locus controlling apomixis in Pennisetum squamulatum (syn Cenchrus squamulatus) and Cenchrus ciliaris (syn Pennisetum ...

Population dynamics, survival, and movements of Texas tortoises in a national park in southern Texas

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Texas tortoise abundance in a small national park in South Texas, USA, declined by >25%, from an estimated 273 tortoises in 2014 to 204 tortoises in 2024. The severity of the decline varied across survey units, but abundance remained highest in areas having greater canopy cover and experiencing less invasion by Guinea grass.

Developing an expert elicited simulation model to evaluate invasive species and fire management alternatives

open access: yesEcosphere, 2019
Invasive species can alter ecosystem properties and cause state shifts in landscapes. Resource managers charged with maintaining landscapes require tools to understand implications of alternative actions (or inactions) on landscape structure and function.

Spatial Representativeness of MexFlux as a Regional FLUXNET Network

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Environmental observatory networks are fundamental in advancing scientific understanding of biogeochemical processes. FLUXNET is a global network of regional eddy covariance networks that measure ecosystem‐scale exchanges of greenhouse gases (e.g., CO2, CH4, H2O) and energy between the biosphere and the atmosphere.

Explaining the variation in impacts of non-native plants on local-scale species richness: the role of phylogenetic relatedness [PDF]

open access: yes, 2014
Aim: To assess how the magnitude of impacts of non-native plants on species richness of resident plants and animals varies in relation to the traits and phylogenetic position of the non-native as well as characteristics of the invaded site.Location ...

An iterative and targeted sampling design informed by habitat suitability models for detecting focal plant species over extensive areas [PDF]

open access: yes, 2014
Prioritizing areas for management of non-native invasive plants is critical, as invasive plants can negatively impact plant community structure. Extensive and multi-jurisdictional inventories are essential to prioritize actions aimed at mitigating the ...
