Spatial distribution of freshwater crustaceans in Antarctic and Subantarctic lakes
(Nature, 2019-05-28)
Antarctic and Subantarctic lakes are unique ecosystems with relatively simple food webs, which are likely to be strongly affected by climate warming. While Antarctic freshwater invertebrates are adapted to extreme environmental ...
Genotyping-by-sequencing resolves relationships in Polygonaceae tribe Eriogoneae
(Wiley, 2021-08)
The resolution of cryptic diversity is essential for understanding the evolutionary diversification of lineages and establishing conservation priorities. We examine relationships in Eriogoneae (Polygonaceae), a diverse ...
Biotic vs. Abiotic Control of Decomposition: A Comparison of the Effects of Simulated Extinctions and Changes in Temperature
(Public Library of Science, 2014-01)
The loss of species is known to have significant effects on ecosystem functioning, but only recently has it been recognized that species loss might rival the effects of other forms of environmental change on ecosystem ...
Distance decay 2.0 – A global synthesis of taxonomic and functional turnover in ecological communities
(Wiley, 2022-07)
Aim: Understanding the variation in community composition and species abundances (i.e., beta-diversity) is at the heart of community ecology. A common approach to examine beta-diversity is to evaluate directional variation ...
Depletion of the heaviest stable N isotope is associated with NH4 +/NH3 toxicity in NH4 +-fed plants
(BioMed Central, 2011-05-16)
Background: In plants, nitrate (NO(3)(-)) nutrition gives rise to a natural N isotopic signature (delta(15)N), which correlates with the delta(15)N of the N source. However, little is known about the relationship between ...
Plastidic Phosphoglucose Isomerase Is an Important Determinant of Starch Accumulation in Mesophyll Cells, Growth, Photosynthetic Capacity, and Biosynthesis of Plastidic Cytokinins in Arabidopsis
(Public Library of Science, 2015-03-26)
Phosphoglucose isomerase (PGI) catalyzes the reversible isomerization of glucose-6-phosphate and fructose-6-phosphate. It is involved in glycolysis and in the regeneration of glucose-6-P molecules in the oxidative pentose ...
Nitrogen Source and External Medium pH Interaction Differentially Affects Root and Shoot Metabolism in Arabidopsis
(Frontiers Media, 2016-02-01)
Ammonium nutrition often represents an important growth-limiting stress in plants. Some of the symptoms that plants present under ammonium nutrition have been associated with pH deregulation, in fact external medium pH ...
A wheat cysteine-rich receptor-like kinase confersbroad-spectrum resistance against Septoria tritici blotch
(Nature, 2021-01-19)
The poverty of disease resistance gene reservoirs limits the breeding of crops for durable resistance against evolutionary dynamic pathogens. Zymoseptoria tritici which causes Septoria tritici blotch (STB), represents one ...
Acceptance of Near-Natural Greenspace Management Relates to Ecological and Socio-Cultural Assigned Values Among European Urbanites
(Elsevier, 2021-02)
Grasslands are widespread elements of urban greenspace providing recreational, psychological and aesthetic benefits to city residents. Two urban grassland types of contrasting management dominate urban greenspaces: frequently ...
Comparison of Sampling Methods for Benthic Macroinvertebrates in Forested Wetlands
(Elsevier, 2021-06)
Forest wetlands are biodiversity hotspots that perform functions of vital ecological importance, but they are among the world's most threatened ecosystems. Due to their high diversity of habitats and species, the study of ...
