Habitat characteristics along spring migration routes of elk, mule deer, and pronghorn in the southern San Juan Mountains

The Journal of Wildlife Management, EarlyView.
We evaluated habitat characteristics of spring migration routes and stopover sites for adult female elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) in the San Juan Mountains (2021–2022) and found species‐specific differences in vegetation structure, terrain, and proximity to land cover types relative to ...

Prospects and Constraints of Lowest Astronomical Tide (LAT) as Determination of Sea Boundaries in Indonesia

Egyptian Journal of Aquatic Research, 2023
The determination of the maritime boundary is related to the selection of the tidal datum used in relation to the zero-depth reference. This research was conducted to determine the impact of the zero-depth reference that has been used, the Mean Low Water

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

River Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

A Curvelet-Transform-Based Image Fusion Method Incorporating Side-Scan Sonar Image Features

Journal of Marine Science and Engineering, 2023
Current methods of fusing side-scan sonar images fail to tackle the issues of shadow removal, preservation of information from adjacent strip images, and maintenance of image clarity and contrast. To address these deficiencies, a novel curvelet-transform-

Reconstructing Long‐Term Historical Hydrologic Alteration to Support Environmental Flows in Texas

River Research and Applications, EarlyView.
ABSTRACT Understanding and quantifying hydrologic alteration is essential for effective watershed management and ecological conservation. This study developed a modeling framework to predict reference hydrology and assess and model hydrologic alteration across Texas using publicly available geospatial datasets.

The Hidden Harvest: Harnessing Colorado's Geodiversity and Environmental Heterogeneity for Sustainable Agritourism

Sustainable Development, EarlyView.
ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...
