Adjacent environments contribute to the increase of zooplankton species in a neotropical river

open access: yesActa Limnologica Brasiliensia, 2017
Aim: The distribution of the zooplankton community along the Paraná River and in adjacent environments (tributaries and lakes) was evaluated, as well as the contribution of the community present in these environments to the species composition of the ...

The green-leaved variant of Eucalyptus largiflorens: a story involving hybridization and observant local people [PDF]

open access: yes, 2010
Eucalyptus largiflorens (Black Box) is the most common tree in the Chowilla anabranch system on the Murray River floodplain. It typically has dull, glaucous, grey-green leaves.

Lowland river responses to intraplate tectonism and climate forcing quantified with luminescence and cosmogenic 10Be [PDF]

open access: yes, 2013
Intraplate tectonism has produced large-scale folding that steers regional drainage systems, such as the 1600 km-long Cooper Ck, en route to Australia’s continental depocentre at Lake Eyre.

Hydrological Conditions Outweigh Soil Texture, Temperature, and Terrain in German Agricultural Land Use

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The availability of fertile land suitable for agriculture is limited. In the European Union, political demand for self‐sufficiency in staple food production currently competes with increasing ambitions for nature restoration and green energy. Meanwhile, the overall agricultural area shrinks due to land sealing.

Cordilleran Ice Sheet early deglaciation inferred from evolution of Late‐Pleistocene glacial Lake Dzulh Stun in east‐central British Columbia, Canada

open access: yesJournal of Quaternary Science, EarlyView.
Abstract We document the early decay of the Late‐Pleistocene Cordilleran Ice Sheet in the central portion of the Rocky and Cariboo Mountains and the Rocky Mountain Trench in east‐central British Columbia. Glacial lakes impounded at the eastern margin of the ice sheet occupied watersheds on the west flank of the central Rocky Mountains, leaving ...

What is the Direction of Land Change? A New Approach to Land-Change Analysis

open access: yesRemote Sensing, 2017
Accurate characterization of the direction of land change is a neglected aspect of land dynamics. Knowledge on direction of historical land change can be useful information when understanding relative influence of different land-change drivers is of ...

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

Ecology and Genetics of Natural Populations of North American Vitis Species Used as Rootstocks in European Grapevine Breeding Programs

open access: yesFrontiers in Plant Science, 2020
Three North American Vitis species (V. riparia, V. berlandieri, V. rupestris) became widely used in rootstock breeding programs following the expansion of North American pests and diseases introduced in vineyards of the world during the 19th century ...

Comparative studies on the structure of an upland African stream ecosystem [PDF]

open access: yes, 2004
Upland stream systems have been extensively investigated in Europe, North America and Australasia and many of the central ideas concerning their function are based on these systems.

"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...
