Influence of Land Use on the C and N Status of a C4 Invasive Grass in a Semi-Arid Region: Implications for Biomonitoring [PDF]

open access: yesPlants, 2021
Biomonitoring of atmospheric pollution is an increasingly accepted practice. However, most existing biomonitors are usually epiphytic species from mesic environments.

"There Would Be More Black Spaces": Care/giving Cartographies during COVID-19. [PDF]

open access: yesMed Anthropol Q, 2022
Abstract Black geographies, Black feminist anthropology, and related fields have provided substantial evidence attesting to the effects of racially violent spatial practices such as dispossession, racial segregation, mass incarceration, and redlining for the health outcomes and life chances of Black communities and other racialized groups, and ...

Effect of Pollen Storage Duration on Stainability, Fruit Set, and Physical Traits in Date Palm (Phoenix dactylifera L.) Cultivar ‘Mejhoul’ [PDF]

open access: yesPlants
Asynchronous flowering between male and female date palms (Phoenix dactylifera L.) makes pollen storage a practical necessity for growers, especially for cultivars like ‘Mejhoul’, which require artificial pollination. This study examined the stainability

Agriculture creates subtle genetic structure among migratory and nonmigratory populations of burrowing owls throughout North America. [PDF]

open access: yesEcol Evol, 2020
Migration‐driven breeding dispersal in the burrowing owl, whereby long‐distance migrants from Canada and the United States became year‐round residents in the newly created irrigated agriculture areas in northwestern Mexico, may explain the species' population decline in northern latitudes.

Evaluation of Glycosyl-Hydrolases, Phosphatases, Esterases and Proteases as Potential Biomarker for NaCl-Stress Tolerance in Solanum lycopersicum L. Varieties [PDF]

open access: yesMolecules, 2019
Salinity stress limited the production in over 30% of irrigated crops and 7% of dryland agriculture worldwide. The objective was to evaluate the effects of NaCl-stress on the enzymatic activity in tomato.

Genetic differentiation in the southern population of the Fathead Minnow Pimephales promelas Rafinesque (Actinopterygii: Cyprinidae) [PDF]

open access: yesPeerJ, 2019
The North American cyprinid Pimephales promelas is a species with a wide distribution range, occurring in distinct hydrographic basins in Mexico, Canada, and the United States. Previous morphological and meristic analyses of P. promelas concluded that at

Heat flow and thermal regime in the Guaymas Basin, Gulf of California: Estimates of conductive and advective heat transport

open access: yesBasin Research, Volume 35, Issue 4, Page 1308-1328, August 2023., 2023
Heat flow estimated during the IODP Expedition 385 into the Guaymas Basin show that values corrected for sedimentation are between 119 and 1003 mW/m2. Heat is dissipated by conduction for plate ages greater than 0.2 Ma. Off‐axis sill intrusion is being cooled down by hydrothermal circulation.

Digital displacement: The spatialities of contentious politics in China's digital territory

open access: yesTransactions of the Institute of British Geographers, Volume 47, Issue 4, Page 1075-1089, December 2022., 2022
Abstract This paper conceptualises digital displacement as both a way through which the digital, dynamic and fragile spatialities of contentious politics can be examined and as a geographic critique of censorship. Digital displacement, understood here as the act of removing users from the digital places and spaces they wish to remain in and use, often ...

Temporal distribution modelling reveals upstream habitat drying and downstream non‐native introgression are squeezing out an imperiled headwater fish

open access: yesDiversity and Distributions, Volume 27, Issue 3, Page 533-551, March 2021., 2021
Abstract Aim To review the conservation status of Headwater catfish Ictalurus lupus (Girard,1859) in the United States, including quantifying environmental correlates with range contraction and hybridization and introgression with Channel catfish Ictalurus punctatus (Rafinesque, 1818) to inform conservation prioritization. Location Texas and New Mexico,
