Aggregation of two imperfectly detected imperilled freshwater fishes: understanding community structure and co-occurrence for multispecies conservation

open access: yesEndangered Species Research, 2019
Characterizing critical habitat for endangered species is the first step for effective conservation and relies on knowledge of the abiotic conditions that promote species occurrence.

Can Mg isotopes be used to trace cyanobacteria-mediated magnesium carbonate precipitation in alkaline lakes? [PDF]

open access: yes, 2011
The fractionation of Mg isotopes was determined during the cyanobacterial mediated precipitation of hydrous magnesium carbonate precipitation in both natural environments and in the laboratory.

Melatonin-mediated physiological and molecular responses to abiotic stress in horticultural crops

open access: yesHorticultural Plant Journal
Horticultural crops suffer massive production losses due to abiotic stress, which is a key limiting factor worldwide. The ability of these crops to withstand such stress has been linked to melatonin, a biomolecule with significant roles in both ...

The Evolution of Multicomponent Systems at High Pressures: VI. The Thermodynamic Stability of the Hydrogen-Carbon System: The Genesis of Hydrocarbons and the Origin of Petroleum

open access: yes, 2002
The spontaneous genesis of hydrocarbons which comprise natural petroleum have been analyzed by chemical thermodynamic stability theory. The constraints imposed upon chemical evolution by the second law of thermodynamics are briefly reviewed; and the ...

G-protein Signaling Components GCR1 and GPA1 Mediate Responses to Multiple Abiotic Stresses in Arabidopsis [PDF]

open access: yesFrontiers in Plant Science, 2015
G-protein signaling components have been implicated in some individual stress responses in Arabidopsis, but have not been comprehensively evaluated at the genetic and biochemical level. Stress emerged as the largest functional category in our whole transcriptome analyses of knock-out mutants of GCR1 and/or GPA1 in Arabidopsis (Chakraborty et al., 2015a,

Comparative Expression Analysis of Two-Component System Members in Arabidopsis and Oryza sativa under Abiotic Stress

open access: yesFrontiers in Plant Science, 2015
Two component system (TCS) is one of the key signal sensing machinery which enables species to sense environmental stimuli. It essentially comprises of three major components, sensory histidine kinase proteins (HKs), histidine phosphotransfer proteins ...

Fish larvae from the upper Paraná River: do abiotic factors affect larval density?

open access: yesNeotropical Ichthyology
The purpose of this study was to evaluate the role of abiotic factors on fish larvae occurrence. Samplings were carried out monthly at 12 stations (grouped in four areas) in the Amambaí, Ivaí and Paraná rivers and in the Itaipu Reservoir (upper Paraná ...

Global Switches and Fine-Tuning—ABA Modulates Plant Pathogen Defense

open access: yesMolecular Plant-Microbe Interactions, 2008
Plants are obliged to defend themselves against a wide range of biotic and abiotic stresses. Complex regulatory signaling networks mount an appropriate defense response depending on the type of stress that is perceived.
