Populations of two other species – long-billed vulture and slender-billed vulture – dropped by 97%.
In fact, the populations of two of these nations enlisted by the United States in its war against terror -- Armenia and Azerbaijan -- routinely trade charges, each contending that the other is guilty of allowing and even sponsoring terrorist attacks fueled by ethnic rivalry and territorial ambitions.

The researchers said that populations of two large rodent species were responsible for the dispersal of the Brazil nut tree seeds: agoutis and acuchis.
By targeting two different receptors, the radiotracer will have more opportunities to localize in the tumor due to the larger populations of two receptors than that of a single receptor.
The VPA data set was collected from seven male and three female, which reflected human action in both normal conditions and violent scenes; while the EEG data set came from the populations of two distinct: Alcoholic Subjects and Control Subjects.
Bread companies or student homes may be able to provide populations of two separate species of flour beetles that are also allowed to mingle separately and together in chambers of flour.
Patterns of clonal growth in natural populations of two Sagittaria species (Sagittaria trifolia and Sagittaria pygmaea) were studied based on allozyme data, and spatial autocorrelation analysis was employed to assess their clonal structures.
The study compares populations of two typical open farmland bird species, the skylark and the meadow pipit, on fields with open in-field and subsurface drainage systems in Finland.
In this paper, we studied the effects of negative density dependence (NDD) and environmental heterogeneity on populations of two abundant tree fern species, Cyathea caracasana and Alsophila engelii, and how these effects change across a successional gradient.
In this study, biofilm populations of two strains of L. monocytogenes (serotypes 1/2a and 4b) on stainless steel coupons and glass were examined using regular fluorescence microscopy, confocal laser scanning microscopy and classic culture method.
