Wildlife Strikes to Civil Aircraft in the United States 1990-2012
ISBN: 9781495459108 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In 2012, the FAA and USDA continued to make great progress with its multifaceted approach for mitigating wildlife strikes. The FAA ensured that 100 percent of Part 139 airports have completed a Wildlife Hazard Assessment (WHA), are in the process of conducting a WHA, or have taken a Federal grant to conduct a WHA. Strike reporting continued to increase, especially with General Aviation (GA) aircraft, which increased strike reporting by 11 percent between 2011 and 2012. The FAA implemented three performance metrics to monitor strike reporting trends and GA wildlife mitigation. The performance...

Assessment of Rangeland Ecosystem Conditions, Salt Creek Watershed and Dugout Ranch, Southeastern Utah
ISBN: 9781495960994 / Angielski / Miękka / 64 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Increasingly, dry rangelands are being valued for multiple services beyond their traditional value as a forage production system. Additional ecosystem services include the potential to store carbon in the soil and plant biomass. In addition, dust emissions from rangelands might be considered an ecosystem detriment, the opposite of an ecosystem service. Dust emitted may have far-reaching impacts, for example, reduction of local air quality, as well as altering regional water supplies through effects on snowpack. Using an extensive rangeland monitoring dataset in the greater Canyonlands region...

Inventory of Intertidal Habitats: Boston Harbor Islands, A National Park Area
ISBN: 9781492172246 / Angielski / Miękka / 146 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A series of natural resource inventories were conducted throughout the Boston Harbor Islands, including terrestrial, marine and estuarine ecosystems. The resource inventories enhance our appreciation for the habitats and species that occur within the Boston Harbor Islands landscape. These resource inventories provide a scientific foundation for natural resource management decisions, will assist in the design of long-term monitoring programs, and help identify areas requiring additional inventory.

Protocol for Monitoring Aquatic Invertebrates of Small Streams in the Heartland Inventory & Monitoring Network
ISBN: 9781492355090 / Angielski / Miękka / 144 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Aquatic invertebrates are an important biomonitoring tool for understanding and detecting changes in ecosystem integrity over time. Therefore, the monitoring objectives of this protocol as described by DeBacker et al. (2005) are: 1) Determine the status and trends of invertebrate species diversity, abundance, and community metrics. 2) Relate invertebrate community to overall water quality through quantification of metrics related to species richness, abundance, diversity, and region-specific multi-metric indices as indicators of water quality and habitat condition.

Pacific Islands Stream Monitoring Protocol: Fish, Shrimp, Snails, and Habitat Characterization- Pacific Island Network
ISBN: 9781492714361 / Angielski / Miękka / 380 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Throughout the world, freshwater ecosystems are considered to be among the most vulnerable systems. In the isolated Pacific islands there are a relatively small number of native freshwater species, which are mainly endemic to these locations (found nowhere else in the world). These species are characterized by an amphidromous lifecycle; reproducing in the stream, with larvae drifting to the ocean and eventually returning to a stream as juveniles and spending the remainder of their lifecycle there. Throughout the region, native flora and fauna face significant threats from species...
