The influence of the Atlantic and regional climate variability on the long-term changes in gelatinous carnivore populations in the northwestern Mediterranean
the Atlantic regional climate variability long-term changes gelatinous carnivore populations northwestern Mediterranean
2014/4/18
We investigated potential connections between climate and the population size of gelatinous carnivores in the northwestern Mediterranean. The interannual variability of large- and meso-scale climate f...
Long-term changes in abundance and diversity of macrophyte and waterfowl populations in an estuary with exotic macrophytes and improving water quality
Long-term changes in abundance diversity of macrophyte waterfowl populations in an estuary exotic macrophytes improving water quality

Long-term changes in the areal hypolimnetic oxygen deficit (AHOD) of Onondaga Lake: Evidence of sediment feedback
Long-term changes areal hypolimnetic oxygen
2014/4/30
Long-term trends in the rate of depletion of hypolimnetic dissolved oxygen (DO) are documented for ionically
enriched hypereutrophic Onondaga Lake, New York, for the 1978–2002 interval. Depletion rat...
Long-term changes in apparent uptake of silica in the San Francisco estuary
Long-term changes apparent uptake silica San Francisco estuary
2014/5/9
Silica distributions in estuaries can be used to infer uptake, particularly that due to production by diatoms. I used data from two long-term monitoring programs to infer long-term patterns of diatom ...
Long–term changes in the abundance of Jesogammarus annandalei (Tattersall) in Lake Biwa
Long–term Lake Biwa
2014/5/19
Changes in the abundance of an endemic amphipod, Jesogammarus annandalei, that inhabits the profundal zone
of Lake Biwa were examined from 1966 to 1999. The abundance of J. annandalei increased sudde...
