Hydrogeological Investigation and Parameter Analysis of Floodplain Area in the Reaches of the Yangtze River [PDF]

E3S Web of Conferences, 2019
The binary structure of the floodplain in the reaches of the Yangtze River is obvious and has unique hydrogeological features. In this paper, the hydrogeological survey of the floodplain area is carried out.

Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

Using the Relative Elevation Models to delimit the floodplain level development: The case of the braided-wandering Belá River, Slovakia

Moravian Geographical Reports
The Belá River is a specific submountain river running through the Liptov Basin in the Slovak Carpathians. Its transformation from a braided to a braided-wandering system and degradation including incision of the river system has been observed since the ...

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

The Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

Land Degradation &Development, EarlyView.
ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...

Bauhinia naniflora: a new species of section Amaria (Cercidoideae: Leguminosae) from Colombia

Nordic Journal of Botany, EarlyView.
Bauhinia, the most species‐rich genus of Cercidoideae (Leguminosae), is pantropically distributed and includes four sections in the Americas. During an ongoing taxonomic revision of American Cercidoideae, a new species of Bauhinia sect. Amaria ser. Decandrae currently endemic to Colombia was identified and is here described as Bauhinia naniflorasp nov.

The effects of river patterns on riparian vegetation: A comparison of anabranching and single-thread incised channels

Moravian Geographical Reports, 2016
Riparian vegetation reflects the current conditions and the dynamics of streams. The floodplain vegetation along the watercourse of the Morávka River was subject to study in this project.

Urbanization and food transition in the Brazilian Amazon: From wild to domesticated meat

People and Nature, EarlyView.
Abstract Urbanization is expected to influence food transitions, resulting in a shift from wild foods to more domesticated foods. Concomitantly, food insecurity and urban demand for natural resources, including wildlife, are expected to increase overall, even when the per capita consumption is expected to decrease.

Floodplains: the forgotten and abused component of the fluvial system

E3S Web of Conferences, 2016
River restoration is strongly focussed on in-channel initiatives driven by fisheries interests and a continued desire for river stability. This contrasts greatly with the inherently mobile nature of watercourses. What is often overlooked is the fact that

Preparation of Seven Certified Reference Materials for Floodplain Sediments

Yankuang ceshi, 2018
BACKGROUND Floodplain sediment, which is an important sampling media for geochemical mapping, can represent the average distribution of elements in the basins and has universal applicability. At present, there is no floodplain sediment reference material
