Coyote density, demography, and genetic structure across North Carolina's barrier islands

The Journal of Wildlife Management, EarlyView.
Coyotes colonized North Carolina's barrier islands beginning in the late 2000s, where park managers have documented that they prey on protected shorebird and sea turtle nests. Using fecal DNA, we estimated coyote density across 7 islands, which ranged from 0.04–1.01 coyotes/km2 and generally declined with isolation. Abstract Beginning in the late 2000s,

InSAR based deformation mapping of earthquake using Sentinel 1A imagery

, 2020
Development of synthetic aperture radar (SAR) based satellites provide remedies to major geohazards under critical situations around the world. Sentinel 1A mission with the revisit period of 12 days helps to serve the objective in an effective manner ...

Prey detection by the predator remains constant across prey densities: evidence from a field experiment in the Arctic tundra

Oikos, EarlyView.
The functional response describes how predator acquisition rates change with prey availability and integrates behavioural processes that occur during predator–prey encounters. Among these processes, prey detection represents a critical yet often overlooked component that can directly influence population dynamics. Variation in detection probability has

Early Growth Response 1‐Associated Epithelial Autophagy‐Related Changes in Allergic Airway Inflammation

Pediatric Discovery, EarlyView.
House dust mite (HDM) exposure induces early growth response 1 (EGR1) expression in airway epithelial cells and is accompanied by autophagy‐associated alterations, including increased LC3B‐II and Vps34 levels and decreased p62 abundance. Manipulation of EGR1 expression modulates these autophagy‐related changes, whereas pharmacological inhibition of ...

Composite Fibers of Hydroxypropyl Cellulose and Alginate Spun From Aqueous Solution: Crosslinking Effects on Water Absorption and Mechanical Properties

Polymer Engineering &Science, EarlyView.
Alginate‐HPC composite fibers spun via CaCl2‐induced gelation process. Fiber diameter ranges from 100 to 200 μm after air drying. Higher alginate boosts water absorption in dried fibers. HPC selectively diffuses out when fibers are soaked in water. Crosslinking with hexamethylene diisocyanate improves mechanical strength.

Sentinel 1a-2a Incorporating an Object-Based Image Analysis Method for Flood Mapping and Extent Assessment [PDF]

This study presents flood extent extraction and mapping from Sentinel images. Here we suggest an algorithm for extracting flooded areas from object-based image analysis (OBIA) using Sentinel-1A and Sentinel-2A images to map and assess the flood extent ...
