Abstract:

Dispersal is a fundamental ecological and evolutionary process that can create demographic and genetic linkage between neighbouring and distant locations, influencing the dynamics, structure and ultimately the persistence of populations. To understand observed population dynamics and structure and to predict future change, accurate and comprehensive data are required describing the pattern and magnitude of dispersal and gene flow across all relevant spatial scales. However, this is a major empirical challenge. In this thesis, I aimed to obtain comprehensive empirical data quantifying natal dis

Abstract:

Changes in climate shape biological populations. They can alter spatial distributions, the timing of life history events, and even the species themselves. We are now experiencing a period of rapid directional climate change, alongside seasonal fluctuations. This thesis investigates temporal changes in life history events, phenology, as a climate response. I explore the causes and population level consequences of change in breeding phenology of two wild bird populations from Wytham Woods, UK. I test how great tits (Parus major) and blue tits (Cyanistes caeruleus) achieve temporal synchrony betw

Abstract:

Dispersal influences the genetic and social composition of populations, yet it has been difficult to understand the mechanisms underlying dispersal and this limits our ability to understand how dispersal may be influencing population dynamics. Behavioral traits, such as aggression, have been implicated as drivers of both dispersal and population dynamics. However, the influence on both has never been addressed in a single system. Western bluebirds (Sialia mexicana) provide an excellent opportunity to address this question, as their dispersal propensity is dependent upon aggressive phenotype an

Abstract:

Habitat alteration and climate change are among the anthropogenic factors that contribute most to the current global decline of biodiversity. Due to their sensitivity to environmental conditions, birds are considered excellent indicators of global change. In particular, long-distance migrants are likely more sensitive to global change than residents or short-distance migrants because they suffer from changes in ecological conditions both at their breeding and wintering quarters The aim of this thesis is to investigate the effects of climate change and habitat modification on population dynamic

Abstract:

The winter period is typically associated with harsh weather conditions and reduced food availability, which may lead to increased mortality. In birds, a common strategy to avoid such risks is to migrate to more favourable grounds, but its demographic costs are largely unknown. The wintering season remains a black box in our knowledge of the life cycle of birds. From the perspective of a wintering area, I study the population ecology of a migratory species, based on the hypothesis that winter aggregations of birds constitute true populations, instead of random aggregations of individuals.

Farmland bird populations in Europe have been in decline for a long time. Agricultural intensification and growing a large share of crops that provide suboptimal breeding habitat could be the main causes of the observed decline. To explore these possible drivers, I focused on population trends of farmland bird species in different habitats in the Czech Republic over the periods 1982-1990 and 1990-2010. Specifically, I focused on the variability in trends within each species in respect to the differences in landscape management between the lowlands and mid-altitude areas before and after 1990.
