abundance

Although we did not find an effect of the flood event on abundance, we did find large variability in estimated abundances between the 2 y at our three sentinel sites.

Abundances of small, medium, and large melonworm larvae during the 2nd planting (28 Jun) were significantly different among sampling dates from 18 Jul to 8 Aug ([F.sub.3,564] = 113.75; P< 0.001), larval sizes ([F.sub.2,564] = 40.58; P < 0.001), and interaction of sampling dates and larval sizes ([F.sub.6,564]= 16.35; P < 0.001) (Fig.

Pearson's correlation coefficient analysis of individuals' data indicated that there were significant correlations of abundances distribution among seasons (P < 0.050).

In addition to biomass, sediment resuspension has been correlated with high abundances of zooplankters in the Nichupte lagoon system (Mexico) (Alvarez-Cardena et al., 2007) and in the Great Barrier Reef (McKinnon et al., 2007).

Habitat generalists were affected by isolation (higher abundances in isolated versus connected hedges) but not by habitat type (forest edge versus hedge), probably because they frequently use various landscape elements such as forests, grasslands or agricultural fields as habitat or as food source (Pollard and Relton 1970, Bentley et al.

Environmental Conditions--Larval tick abundances were positively correlated with temperature; no significant relationship existed for relative humidity.

ABSTRACT A time series abundance analysis of adult and juvenile Haliotis fulgens living in the central region of Baja California Sur, Mexico, was performed and its potential application to fishery management as a predictor of future catches was assessed.

2 Assessing elemental abundances in stellar spectra

Aerial survey has been used as a tool to assess species abundance for both terrestrial and marine vertebrates, often where the remoteness or vastness of the survey area and the potentially low abundance of the study species render other techniques uneconomical [1-6].

There also is evidence that hedgerows may increase the abundance of beneficial insects such as pollinators and natural enemies, possibly improving crop pollination and biological pest control in adjacent crops (Griffiths et al.

Macrozoobenthos respond to a restricted oxygen content with a decreasing species number, abundance, and biomass (Kajak, 1988; Int Panis et al., 1995; Jonasson, 1996; Bazzanti et al., 1998).

We conducted three types of analyses: 1) spatial and temporal analyses to compare the abundances of wild and hatchery chum salmon fry; 2) spatial and temporal analyses to contrast the body sizes of hatchery and wild chum salmon fry; and 3) analyses to correlate the distribution and size of wild chum fry with hatchery fry distribution, sea surface temperature, and salinity.

Oviposition traps were used to investigate the presence and abundances of dengue vectors (Ae.

Stars and their planets form out of the same natal gas cloud, which leaves its impression on a star's metallicity: the abundance of elements heavier than hydrogen and helium.

tenuifolia and Alnus rhombifollia) have increased dramatically in abundance over the last 50 years.
