Publisher version<br>Conventional (text-based) passwords have shown patterns such as variations on the username, or known passwords such as “password”, “admin” or “12345”. Patterns may similarly be detected in the use of Graphical passwords (GPs). The most significant such pattern - reported by many researchers - is hotspot clustering. This paper qualitatively analyses more than 200 graphical passwords for patterns other than the classically reported hotspots. The qualitative analysis finds that a significant percentage of passwords fall into a small set of patterns; patterns that can be used

Oaks (Quercus robur) are an important substrate for many epiphytic lichens, and with increasing age the bark of oaks becomes suitable for red-listed species. These species may respond to environmental and landscape factors differently, and at different spatial scales. We tested the effect of tree, environmental and land use factors on the occurrence and richness patterns of lichens species at various spatial scales (circles with radius ranging from 28 to 1225 m), in a heterogeneous landscape in South Eastern Sweden.

Streszczenie:

The geographic variation of taxonomic richness may be directly determined by climate through contemporaneous/ecological processes, versus other (e.g., historical/evolutionary processes) that happen to be collinear with contemporaneous climate. In Chapter 1 I evaluated hypotheses from both groups of explanations in North America. If contemporaneous climate controls patterns of richness, then richness should vary with climate through time in the same way that richness varies with current climate through space. Over the last ca. 11,000 yr, richness-temperature relationships remained reasonably

Streszczenie:

Species richness of virtually all high-level taxonomic groups is strongly statistically related to climatic variables such as temperature and precipitation, and consistently so across space and time. These observations are consistent with a causal link between the number of species that occur in a given region and its climate. Although dozens of hypotheses have been proposed, the main mechanisms underlying this pattern remain largely unresolved. And, few ecological studies have attempted to identify regularities in the individual species distributions that make up the richness–climate relation

Animal phyla vary dramatically in species richness (from one species to >1.2 million), but the causes of this variation remain largely unknown. Animals have also evolved striking variation in morphology and ecology, including sessile marine taxa lacking heads, eyes, limbs, and complex organs (e.g., sponges), parasitic worms (e.g., nematodes, platyhelminths), and taxa with eyes, skeletons, limbs, and complex organs that dominate terrestrial ecosystems (arthropods, chordates).

Broad scale geographic variation in species diversity correlates with environmental variables in most taxa, but a mechanistic understanding of this relationship has remained elusive.

Preston observed that the number of individuals per species in species assemblages is log-normally distributed (with two parameters: the total number of individuals, I, and the number of individuals of the rarest species, m). Here, we show that ϕ, a proxy for m, is correlated with environmental variables in several datasets of trees, birds, fish, and invertebrates. Moreover, vari

A major goal of evolutionary biology and ecology is to understand why species richness varies among clades.

Other studies have suggested that richness patterns might be related to variation in rates of climatic-niche evolution. However, few studies, if any, have tested the relative importance of these variables in explaining patterns of richness among clades. Here, we test their relative importance among major clades

I studied the spatial distribution of South African avian species richness from the viewpoint that humans are a substantial modifying force on earth, and have also modified the historical spatial distribution of species richness. The main aim of the thesis is to investigate the way in which humans have modified avian species richness patterns in South Africa at the quarter-degree square (QDS) resolution, which is a phenomenon that has been either overlooked, or not completely clarified, in many previous studies of the same region and data at the same resolution. In particular, I investigated h

Streszczenie:

Die auf verschiedenen Skalen-Ebenen heterogene Verteilung des Artenreichtums fasziniert Naturforscher und Biologen seit Jahrhunderten, so dass eine Vielzahl von Hypothesen zur Erklärung dieser Muster aufgestellt wurde. Es besteht breiter Konsens darüber, dass eine Vielzahl verschiedener Prozesse für die Variation des Artenreichtums verantwortlich ist. Je nachdem welche Taxa, welche Orte und welche räumlichen und zeitlichen Skalen betrachtet werden, wird den verschiedenen Faktoren dabei eine unterschiedlich große Bedeutung zugemessen. Umweltgradienten gelten in diesem Zusammenhang als die wicht

Streszczenie:

I studied avian diversity in three regions of arid Australia, namely Cooper Creek (northern South Australia), and the MacDonnell Ranges and Lake Mackay in the southern Northern Territory. The primary objectives of the study were to document the major correlates of bird species richness and compositional turnover, as measures of alpha and beta diversity, and to see if gradients in both covaried. I tested the hypotheses that primary productivity has ultimate control on bird diversity and vegetation proximate control. Cooper Creek flows intermittently and because of large transmission losses, a n
