The relationship between landscape pattern and ecological process is one of the key issues in landscape ecology. Both the species protection and the bio-disaster prevention are closed linked with the landscape pattern of organism's habitat. Taking Dongting Lake area as a case, this paper studied the characteristics of landscape pattern in typical sampling plots, and analyzed the correlation of mouse capture rate in farmland and in house with the indices reflecting the characteristics of landscape pattern. The results showed that the mouse capture rate in farmland correlated significantly with the landscape aggregation, connection, and mosaic shape, while that in house had a significant correlation with the mosaic shape of construction land. Some suggestions on reducing mouse pest were put forward from the viewpoint of landscape pattern.

To understand heart aging at the single-cell level, we employed single-cell dual omics (scRNA-seq and scATAC-seq) in profiling non-myocytes (non-CMs) from young, middle-aged, and elderly mice. Non-CMs, vital in heart development, physiology, and pathology, are understudied compared to cardiomyocytes. Our analysis revealed aging response heterogeneity and its dynamics over time.

Native ecosystem and biodiversity loss from land use conversion into human-modified landscapes are evident in the United States and globally. In addition to public land conservation, there is an increase in private land conservation through conservation easements (CEs) across exurban landscapes. Not every CE was established strictly for biodiversity protection and permitted land uses can increase human modification.

Seabirds are particularly susceptible to potentially toxic elements (PTEs) due to the tendency of biomagnification of some elements, thus serving as potential bioindicators for assessing environmental health. In this study, we analyzed As, Cd, Cu and Zn concentrations in liver samples from nine seabird species (51 specimens) collected along the Southwestern Atlantic Ocean. Results revealed substantial variations in PTE concentrations among species, with taxonomic orders influencing accumulation patterns.

Releases of coal combustion and nuclear fission wastes create contaminated landscapes that pose long-term management challenges. Efforts to facilitate the natural attenuation of legacy wastes in the environment can provide attractive habitat for passerine birds. Passerines have diverse foraging and nesting behaviors that lead to heterogenous contaminant exposure, yet few studies investigate contaminant uptake in passerines on a community scale.

Neuroimaging techniques including functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) have shown promise in detecting functional abnormalities in various brain disorders. However, existing studies often focus on a single domain or modality, neglecting the valuable complementary information offered by multiple domains from both fMRI and EEG, which is crucial for a comprehensive representation of disorder pathology. This limitation poses a challenge in effectively leveraging the synergistic information derived from these modalities.
