Not exact matches

The first U.S. State of the Birds report came out in 2009 and established the precedent of using birds that are confined to specific habitats as indicators of the health of those habitats: oceans, coasts, wetlands, arctic, forests, grasslands, and aridlands.

For the last decade, scientists have deployed increasingly capable underwater robots to map and monitor pockets of the ocean to track the health of fisheries, and survey marine habitats and species.

(A) describes the impacts of climate change and ocean acidification on the diversity and health of the fish, wildlife and plant populations, habitats, ecosystems, and associated ecological processes;

Now, history waits for the IWC to act decisively for whale conservation and the preservation and health of ocean habits, by transcending the question of whaling and extending its role in relation to the myriad troubles that beset the world's whales and their habitats.»

(A) describes the impacts of climate change and ocean acidification on the diversity and health of the fish, wildlife and plant populations, habitats, ecosystems, and associated ecological processes;

For example, reductions in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.134

There is growing concern over the decline of fisheries and the overall health of the ocean: scientists estimate that 90 % of stocks are fished at or beyond sustainable limits, habitats like coral reefs are threatened by ocean acidification, and large areas of ocean and coastlines are polluted.
