The mean abundances
distribution in different habitats was checked by Pearson's correlation coefficients among seasons (Ge et al.
However, adult tick abundances
were positively correlated with relative humidity.
KEY WORDS: abalone, time series, forecasting abundance

Still, Payne was cautious relative to extending her results as reflecting the internal composition of the stars: " The observations on abundances
refer merely to the stellar atmosphere, and it is not possible to arrive in this way at conclusions as to internal composition.
Consequently, mosquito abundance
and the transmission of many mosquitoborne pathogens can be affected by hydrologic variability, in particular, fluctuations in the water cycle that alter the availability of suitable aquatic habitats.
Of three species that showed a 10-fold decline in abundance
in fragments compared to continuous forest, two were predators, one fed on fungal spores, one was large, two were small, their natural abundances
ranged from low to high, one was a carabid, and two were staphylinids.
In each tank, three replicates were taken at 0, 3, 6, and 9 days to measure phytoplankton abundance
Since construction of the Endicott Causeway, fish and oceanographic monitoring studies have been conducted at the four original 1982 baseline stations, providing a large database on species abundance
and water temperature and salinity in the Sagavanirktok Delta (Cannon et al.
We used the 79 monitoring samples to examine the temporal distribution and patterns of abundance
of both species.
But there was no difference in relative abundances
of pest and beneficial insects between the two years (year by insect type interaction; F[sub.
As to total biomasses or abundances
, only total biomass without Chaoborus was significantly connected to layers.
Large patches that had an abundance
of females in 1995 had the highest abundances
Our assumption is that if two independent estimates do not reflect true population abundances
, their variations would not be correlated to one another.
1997) indicated that present-day abundances
, even on the medium-mortality beds, are below such densities, but abundances
in the 1970s were very likely high enough and medium-mortality abundances
circa 2002 (Fig.
The new value is also at odds with well-established correlations between deuterium and measured abundances
of other elements in stars and the gases between them.
