Where did they come from, where did they go? Niche conservatism in woody and herbaceous plants and implications for plant-based paleoclimatic reconstructions. [PDF]
Am J BotAbstract Premise The ecological conditions that constrain plants to an environmental niche are assumed to be constant through time. While the fossil record has been used previously to test for niche conservatism of woody flowering plants, additional studies are needed in other plant groups especially since they can provide insight with paleoclimatic ...

Using model systems to unravel host–Pseudomonas aeruginosa interactions
Environmental Microbiology, Volume 25, Issue 10, Page 1765-1784, October 2023., 2023 Abstract Using model systems in infection biology has led to the discoveries of many pathogen‐encoded virulence factors and critical host immune factors to fight pathogenic infections. Studies of the remarkable Pseudomonas aeruginosa bacterium that infects and causes disease in hosts as divergent as humans and plants afford unique opportunities to shed

Drought and social conflict in rural Zimbabwe: Does the burden fall on women and girls?
Review of Development Economics, Volume 27, Issue 1, Page 178-197, February 2023., 2023 Abstract Climate change–induced extreme weather events such as drought have occurred with increasing frequency and intensity in Zimbabwe over the past 30 years bringing about pressure on communally owned water resources. Using the Zimbabwe Vulnerability Assessment Committee 2020 survey of rural households in Zimbabwe, this study assesses the impact of ...

Hydrological Processes, Volume 35, Issue 12, December 2021., 2021 We integrated results of the BMM with informative priors and top‐kriging. Reduced N stored in soil is an important source for stream N in a mesoscale catchment. Manure and sewage is the main NO3− source in agricultural sub‐catchments. Denitrification played only a minor role in controlling regional scale NO3− export.

Mineralogical & Petrographic Microfacies Study of the Zahraa formation (Pliocene– Pleistocene) in Sawa Lake Surrounding area- IRAQ [PDF]
Muthanna Journal of Pure Science, 2017 "Mineralogical, Petorographic Microfacies study has been done on (16) samples of Zahraa formation (Pliocene – Pleistocene) of outcrop in Surrounded Sawa Lake area. The mineralogical study showed that Calcite is the main mineral within the rock formation, whereas the upper rocks of Zahraa Formation consist silty or sandy claystone is dominant in the ...
