Monitoring the frequency changes of hard and non-degradable ostracod shells can provide valuable information about the past conditions of inland wetlands sediments as a biological index. In this regard, a sediment core with a length of 38 cm was harvested using a static sediment core sampler at the beginning of the delta of Gavkhooni international wetland (Shakh-Kenar station) in April 2019, an...
Abstract. Enhanced summer insolation over North Africa induced a monsoon precipitation increase during the mid-Holocene, about 6000 years ago, and led to widespread expansion of lakes wetlands in present-day Sahara. This is documented paleoenvironmental sediment records, but spatially sparse often discontinuous records provide only fragmentary picture. Previous simulation studies prescribed eit...
Australian inland riparian wetlands located east of the Great Dividing Range exhibit unique, hydroecological characteristics. These flood-dependent aquatic systems in water-limited regions are declining rapidly due to competitive demand for water human activities, as well climate change and variability. However, there exist very few reliable data characterize inundation conditions quantify impa...
The federal government requires those who destroy wetlands to preserve, restore, or create new ones with the goal of no net loss of wetlands. In the summer of 2000, we tested whether forested wetlands created an average of 8 years earlier had developed avian communities similar to natural wetlands of the same age in southeastern Virginia. We compared six created wetlands to five natural (refere...
Aim Natural wetlands are widely considered important for mitigation of climate change, but they have been impacted by land use and cover change (LULCC), often resulting in ecosystem degradation significant changes soil carbon (C) nitrogen (N) dynamics. However, the impact various LULCC types on wetland C N dynamics remains unclear. Location Global. Time period 1982–2021. Major taxa studied Wetl...
The persistent rise in concentrations of greenhouse gases (GHGs) the earth’s atmosphere is responsible for global warming and climate change. Besides known source GHGs emissions like energy, industry, agriculture, intrinsic from natural inland water bodies wetland, rivers, reservoirs, estuaries, etc. have also been identified as other hotspots emission gaining attention scientific communities r...
Several studies had been tried to illustrate the paleo coastlines of the Persian Gulf during the Holocene. A review of those researches reflects the fact that all of them have stablished their facts based on the sedimentary environment interpretations with no quantitative evidence. Generally, the study area is a changing environment which is a combination of riverine, continental, coastal and e...
