Reproductive modes in populations of late-acting self-incompatible and self-compatible polyploid Ludwigia grandiflora subsp. hexapetala in western Europe

Peer Community Journal
Reproductive mode, i.e., the proportion of individuals produced by clonality, selfing and outcrossing in populations, determines how hereditary material is transmitted through generations. It shapes genetic diversity and its structure over time and space,

Nitrogen Cycling from Increased Soil Organic Carbon Contributes Both Positively and Negatively to Ecosystem Services in Wheat Agro-Ecosystems

Frontiers in Plant Science, 2017
Soil organic carbon (SOC) is an important and manageable property of soils that impacts on multiple ecosystem services through its effect on soil processes such as nitrogen (N) cycling and soil physical properties.

Nitrogen use aggravates bacterial diversity and network complexity responses to temperature

Scientific Reports, 2022
Rising temperature affects microbial composition and function in agriculture field, especially under nitrogen fertilization. In this study, we investigated the bacterial community of paddy soil incubated at controlled temperatures (5 °C, 15 °C, 25 °C ...

Livestock tracks transform resource distribution on terracette landscapes of the Loess Plateau

Ecosphere, 2016
Striking networks of livestock tracks, or terracettes, molded to the contours are a common feature on hilly rangelands of the semiarid Loess Plateau, one of the regions with the most severe soil erosion in the world.

Transcriptomic Analysis of Seed Germination Under Salt Stress in Two Desert Sister Species (Populus euphratica and P. pruinosa)

Frontiers in Genetics, 2019
As a major abiotic stress, soil salinity limits seed germination and plant growth, development and production. Seed germination is highly related not only to the seedlings survival rate but also subsequent vegetative growth.

Distinct patterns of natural selection in Na+/H+ antiporter genes in Populus euphratica and Populus pruinosa

Ecology and Evolution, 2017
Salt tolerance genes constitute an important class of loci in plant genomes. Little is known about the extent to which natural selection in saline environments has acted upon these loci, and what types of nucleotide diversity such selection has given ...

GRAPH THEORY APPLIATIONS ON AGRO-ECOSYSTEM

, 2022
An Agro-ecosystem is always directed by the population interactions living in it and also depends on many aboitic factors. There will be a direct or indirect influence of the elements of the ecosystem. Graph theory is used in different areas which provides a powerful tool to model these direct and indirect interactions.
