Colonial, more widely distributed and less abundant bird species undergo wider population fluctuations independent of their population trend

Abstract: Understanding temporal variability in population size is important for conservation biology because wide population fluctuations increase the risk of extinction. Previous studies suggested that certain ecological, demographic, life-history and genetic characteristics of species might be related to the degree of their population fluctuations. We checked whether that was the case in a large sample of 231 European breeding bird species while taking a number of potentially confounding factors such as population tr… Show more

“…1 Although the guinea fowl and pheasant are the least concern species constituting the extremely large populations, 2 their local level can change due to the various reasons, alike demographic casualty and geographical distribution as well as reproductive rate and the susceptibility for environmental changes. 3 An equally important factor affecting population is a genetic diversity that represents the genetic difference within population or between the populations. Genetic diversity conditioned by allelic diversity and heterozygosity is desirable for maintenance of the proper population status, 4 providing its potential for long-term adaptation and fitness.…”

“…Further, we estimated demographic parameters for the best model and generated 500 datasets based on the posterior distribution to estimate the bias and precision in parameter estimation. We assumed a generation time of 1 year for all three species, which is a widespread estimate for the generation time of such small-sized passerines [ 63 ].…”

“…Large temporal variation in animal species hinders the ease with which time series for abundance can be used to accurately assess and predict population trends through time (Bjørnstad & Grenfell, 2001; Buschke et al, 2021; Sæther et al, 2004). While large population fluctuations are seen across the animal kingdom (Gravel et al, 2011), time series of abundance are particularly variable for colonially breeding birds (Anderson et al, 2017; Cuervo & Møller, 2017). Here, we study population abundance time series of the Adélie penguin Pygoscelis adeliae , a well‐studied colonially breeding Antarctic seabird.…”

“…Heavy‐tailed dynamics in animal populations and the associated extreme events (Anderson et al, 2017) have significant consequences for population viability (Cuervo & Møller, 2017; Fey et al, 2015). Because of their disproportional effect on the systems in which they occur, these ‘black‐swan’ events are an important consideration in predicting the persistence and viability of animal populations (Boyce, 1992; Mangel & Tier, 1994).…”
