Evaluation of the Effects of Tigris River Water Quality on the Rotifers Community in Northern Baghdad by using the Canadian Water Quality Index (CCME-WQI)

Iraqi Journal of Science, 2022
     The water quality index was used for the evaluation of the quality of water, as well its impacts on the rotifer abundance, in the Tigris River as it passes through Mishahda City, northern Baghdad.

Temporal, Spatial and Prey Niche Partitioning Reveals Coexistence Mechanism of Mesocarnivores in Guangdong Province, South China

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Through examining the three ecological niche dimensions, we found spatial and prey niche partitioning could help explain mesocarnivore coexistence patterns in Guangdong Province, southern China. ABSTRACT Mesocarnivores are expected to maintain ecosystem function and stability as emerging apex predators after the decline and extinction of large ...

Modelling Species Distribution at the Boundaries of the Earth's Climate

Global Ecology and Biogeography, Volume 34, Issue 7, July 2025.
ABSTRACT Aim Correlative species distribution models (SDMs) are widely used to project species' responses to global changes. The climatic niche of a species is calibrated under current climate conditions and then projected in space and/or time, making model extrapolation an important concern. This issue is particularly relevant when considering species

Physicochemical and mineral properties of suspended sediments of the Tigris and Euphrates rivers in the Mesopotamian Plain.

Science of the Total Environment
Most of the suspended river load from the Tigris and Euphrates rivers is deposited in the Mesopotamian Plain in Iraq. This suspended river load comprises sediments consisting of minerals and organic particles generated from weathering, erosion, transport,

Spatiotemporal interactions facilitate sympatry in a diverse mammalian community

Ecosphere, Volume 16, Issue 2, February 2025.
Abstract Understanding mechanisms underlying coexistence among potential competitors, and between predators and prey, is a persistent challenge in community ecology. Using 6 years (2013–2018) of camera‐trapping data and species interaction models, we investigated the spatiotemporal patterns of inter‐ and intra‐guild interspecific interactions in a ...

The risk of inbreeding versus outbreeding depression in managing an endangered and locally adapted population of a sedentary bird

Conservation Science and Practice, Volume 6, Issue 12, December 2024.
There is ongoing debate in conservation genomics on how to preserve small and fragmented populations, whether they should be managed independently or blended through translocations. This study using genetic and phenotypic data from Red grouse Lagopus scotica in a large British population and endangered Irish population found significant divergence and ...

Using Heavy Metals Pollution Indices for Assessment of Tigris River Water Within Al-Tarmiya City, Northern Baghdad, Iraq

Ecological Engineering & Environmental Technology
The objectives of the study were to (1) identify and measure the concentration of five toxic elements in the Tigris water, (2) determine the threat of these metals in water by various pollution indices such as pollution index (PI) as single index, metal ...

Water quality assessment along Tigris River (Iraq) using water quality index (WQI) and GIS software

Arabian Journal of Geosciences, 2020
Most of the third world countries having rivers passing through them suffer from the water contaminant problem. This problem is considered so difficult to get the water quality within the standard allowable limits for drinking, as well as for industrial ...

Development and validation of a GT‐seq panel for genetic monitoring in a threatened species using minimally invasive sampling

Ecology and Evolution, Volume 14, Issue 5, May 2024.
Here, we develop, optimize, and validate a GT‐seq panel for the federally threatened northern Idaho ground squirrel (Urocitellus brunneus) to provide a standardized approach for future genetic monitoring and assessment of recovery goals using minimally invasive samples.
