Hence, as an important research content of bird population ecology, it is worthy of continued concern to reveal the influence mechanism of long-term climate change on bird population dynamics (Bergmann, 1999).
In Brazil, studies on bivalve mollusks mainly involve spatial distribution and abundance (Araujo and Rocha-Barreira, 2004), population ecology (Boehs et al., 2008; Oliveira et al., 2011; Rodrigues et al., 2013), and efficiency and selectivity (Pezzuto et al., 2010).

This review integrates five themes mostly considered in isolation, as independent research fields in wildlife conservation: (1) trophy quality and population ecology of hunted species, (2) behavioural ecology of hunted populations and associated avoidance mechanisms, (3) physiological stress in hunted populations, (4) genetic variability and desirable traits, and (5) socio-economic imperatives in wildlife conservation.
There is also a lack of information about this relatively inconspicuous species and its population ecology. The objectives of this research are to establish baseline information about the size and locations of E.

Aldrich (1979 as cited in Carroll, 1984) was the first to link the selection approach (from natural sciences, such as ecology) to organizational theory, giving rise to an Evolutionary Logic of Population Ecology. Similarly, organizational demography and community ecology come together as the product of linking evolution approaches to organizational theory (Carroll, 1984).
We established a laboratory-bred population of golden mice to quantify survivorship and reproductive success of adult pairs when released into their natural habitat and to compare these parameters with a native population of golden mice inhabiting the same forest-edge habitat--important information for conservation management and future studies in small mammal population ecology.

Within the fire's 9,809 hectares (24,238 acres) bum zone was the entire campus of California State University Channel Islands, home to our on-going exploration of Tyto alba (Bam Owl) population ecology. The Springs fire offered the unique opportunity to explore how Tyto diet changes in the immediate wake of such a complete burn event/ disturbance.
