The proposed action being addressed in this Regulatory Impact Review (RIR) and Regulatory Flexibility Act Analysis (RFAA) is the designation of critical habitat in waters of the North Pacific Ocean for the northern right whale under authority of the Endangered Species Act (ESA). The purpose of this RIR/RFAA is to evaluate, to the extent practicable, the economic, socioeconomic, and other costs ...

Biting midges are small nematocerous Diptera. Culicoides and Dasyhelea two important genera of the family Ceratopogonidae. Larvae innoxius aprojecta found in semiaquatic moist habitat. The larvae feed on debris habitat substrata. materials consumed by these aid their development to become adult. nutritional evaluation food material C. D. was carried out know essential element

brown bear (ursus arctos) is one of the most important carnivores in iran. however, information on its habitat associations is scared. based on ecological niche factor analysis (enfa) method, a summer habitat suitability model was developed for this species in the southern part of alborz protected area. our results showed that, brown bears prefer higher altitudes and northern aspects in their p...

The direct effects of CO2 level changes on plant water availability are usually ignored in plant habitat models. We compare traditional proxies for water availability with changes in soil water (fAWC) predicted by a process-based ecosystem model, which simulates changes in vegetation structure and functioning, including CO2 physiological effects. We modelled current and future habitats of 108 E...

Habitat monitoring of designated areas under the EU Habitats Directive requires every 6 years spatially explicit information on area, range, structure and function for the protected (Annex I) habitat types. Hyperspectral remote sensing could be an important technique to assist in the evaluation of the habitat conservation status by providing continuous maps of habitat quality indicators (e.g., ...

Forage is one of the main products of rangeland ecosystems, which is threatened by different anthropogenic disturbances. This study was conducted to assess the impact of urbanization, rural development, agriculture extension, road construction and industry on forage production in an arid and semiarid rangeland using InVEST habitat quality model in spring 2018. In 14 rangeland types, thirty 2×1m...
