Community Structure and Soil Environmental Drivers of Rhizosphere and Root Endophytic Microbiota of Polygonum divaricatum in a Temperate Grassland

Biology
Understanding the ecological drivers of plant-associated microbiota is essential for predicting grassland ecosystem resilience. This study aimed to characterize the community structure, functional potential, and soil environmental drivers of rhizosphere ...

Variation in the morphology of the wings of the endangered grass-feeding butterfly Coenonympha oedippus (Lepidoptera: Nymphalidae) in response to contrasting habitats

European Journal of Entomology, 2018
At the southern limit of its range the endangered butterfly Coenonympha oedippus inhabits grasslands (wet, dry) that differ significantly in the abundance of its larval hostplants (wet > dry) and mean annual air temperature (wet < dry).

Land Heterogeneity, Agricultural Income Forgone and Environmental Benefit: An Assessment of Incentive Compatibility Problems in Environmental Stewardship Schemes [PDF]

This paper examines the issue of incentive-compatibility within environmental stewardship schemes where incentive payments to farmers to provide environmental goods and services are based on foregone agricultural income. The particular focus of the paper

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

A conceptual framework for the temporal dynamics of spatial environmental heterogeneity–biodiversity relationships

Frontiers in Ecology and Evolution
Environmental heterogeneity is an important spatial characteristic, the loss of which is thought to reduce biodiversity by decreasing the availability of niche space.

ZONEAMENTOS AMBIENTAIS: QUANDO UMA UNIDADE TERRITORIAL PODE SER CONSIDERADA HOMOGÊNEA? [PDF]

Revista Brasileira de Cartografia, 2007
In environmental zoning territorial units are delimited that, for definition of guidelines, they are considered homogeneous. However, it is recognized that there is a variability interns not acted in map, matter to each one of them, be in the composition,

Adjustment of pigment composition in Desmarestia (Desmarestiaceae) species along a sub-Antarctic to Antarctic latitudinal gradient

Polar Research, 2016
Photosynthesis at high latitudes demands efficient strategies of light utilization to maintain algal fitness and performance. The fitness, and physiological adaptation, of a plant or algae species depends in part on the abundance and efficiency of the ...

Voting for environmental policy under income and preference heterogeneity [PDF]

We examine the design of policies for promoting the consumption of green products under preference and income heterogeneity using organic food products as an example. Two instruments are considered: a price subsidy for the organic food products and a tax

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Facilitation by a Spiny Shrub on a Rhizomatous Clonal Herbaceous in Thicketization-Grassland in Northern China: Increased Soil Resources or Shelter from Herbivores

Frontiers in Plant Science, 2017
The formation of fertility islands by shrubs increases soil resources heterogeneity in thicketization-grasslands. Clonal plants, especially rhizomatous or stoloniferous clonal plants, can form large clonal networks and use heterogeneously distributed ...
