WebApr 19, 2013 · Population fluctuations, or outbreaks, of rodents constitute one of the classic problems of animal ecology, and this book sifts through the last eighty years of research to draw out exactly what we know about rodent outbreaks and what should be the agenda for future research. The author has synthesized the research in this area, focusing mainly ... WebFish population fluctuations have been widely documented and are often attributed to climate variability, but little is known about their relationship. This is a barrier that restricts our capacity to understand climate effects on fish fluctuations. Here, we collected published data to conduct a comparative analysis of time series in terms of both scale deposition …

WebApr 3, 2024 · Past ungulate population fluctuations, with reduced predation, had led to system degradation or dominance of some species at the expense of others (Peterson, 2007; Wagner, 2006). Whether or not this is the desired state for these ecosystems, is a value-laden debate left to humans; it is important to not confuse the issues (Aplet & Cole, … WebDec 28, 2024 · An overview. Population cycles have been well described as periodic multiannual density fluctuations characterized by delayed density dependence in population growth rates (Stenseth 1999).The periodicity may be statistically derived from e.g. simple autocorrelations of abundance in time series data (Begon et al. 1996), autoregressive … colored plastic hangers
