Mechanistic and Correlative Models of Ecological Niches [PDF]

open access: yes, 2015
The suite of factors that drives where and under what conditions a species occurs has become the focus of intense research interest. Three general categories of methods have emerged by which researchers address questions in this area ...

Scavenging of nitric oxide up-regulates photosynthesis under drought in Festuca arundinacea and F. glaucescens but reduces their drought tolerance

open access: yesScientific Reports, 2022
Nitric oxide (NO) has been proven to be involved in the regulation of many physiological processes in plants. Though the contribution of NO in plant response to drought has been demonstrated in numerous studies, this phenomenon remains still not fully ...

Basic principles of temporal dynamics [PDF]

open access: yes, 2019
All ecological disciplines consider temporal dynamics, although relevant concepts have been developed almost independently. We here introduce basic principles of temporal dynamics in ecology.

Spatial and temporal predictions of soil moisture patterns and evaporative losses using TOPMODEL and the GASFLUX model for an Alaskan catchment [PDF]

open access: yesHydrology and Earth System Sciences, 1998
By using topographic indices as derived from a Digital Terrain Models (DTM), it is possible to represent the heterogeneity within a landscape. This heterogeneity can reflect both long term evolutionary patterns seen in a landscape and the short term ...

Burkholderia phytofirmans PsJN Primes Vitis vinifera L. and Confers a Better Tolerance to Low Nonfreezing Temperatures

open access: yesMolecular Plant-Microbe Interactions, 2012
Several endophytic bacteria reportedly induce resistance to biotic stress and abiotic stress tolerance in several plant species. Burkholderia phytofirmans PsJN is a plant-growth-promoting rhizobacterium (PGPR) that is able to colonize grapevine tissues ...

Priming: Getting Ready for Battle

open access: yesMolecular Plant-Microbe Interactions, 2006
Infection of plants by necrotizing pathogens or colonization of plant roots with certain beneficial microbes causes the induction of a unique physiological state called “ priming”.

Exogenous Application of Zinc Oxide Nanoparticles Improved Antioxidants, Photosynthetic, and Yield Traits in Salt-Stressed Maize

open access: yesAgronomy, 2023
Salinity is one of the most threatening abiotic stresses to agricultural production, alarmingly expanding both through natural salinization phenomena and anthropogenic activities in recent times.

Biotic and Abiotic Stress Responses in Crop Plants

open access: yesAgronomy, 2018
Agricultural productivity depends on increasingly extreme weather phenomena, and the use of germplasm that has to be continuously improved by plant breeders to become tolerant to various biotic and abiotic stresses.

The role of Computer Aided Process Engineering in physiology and clinical medicine [PDF]

open access: yes, 2009
This paper discusses the potential role for Computer Aided Process Engineering (CAPE) in developing engineering analysis and design approaches to biological systems across multiple levels—cell signalling networks, gene, protein and metabolic networks ...
