Abstract:
Many species are responding to anthropogenic climate change by shifting their ranges to higher latitudes. Understanding the factors that drive species’ responses will help ecologists and conservationists develop strategies to avoid negative climate change impacts. I investigated shifts at the northern (cool) range margins of 1573 southerly-distributed species from 21 animal groups in Great Britain, over the past four decades. My findings confirm continued polewards range shifts (18 km decade-1 over 1986-2010). I then concentrated on 347 British species from 14 invertebrate taxa, discovering co

Abstract:
The natural environment is being altered by anthropogenic activity at an unprecedented rate. The effects of climate change and damage caused by other human activities show little sign of decelerating. The ubiquity of the forecast changes means that all species are likely to face alterations in their environment and consequently may have to migrate or adapt to avoid extinction. Yet, as species respond they may initiate additional ecological changes, creating further selection pressures on species they interact with. Research has shown that ecological and evolutionary dynamics such as these occu

Foresters can easily calculate the volume and the specific composition of any stand in Lithuania at the moment.

The price is determined by specific composition of the stand, the density, the height of the trees, the average diameter. All these factors are mostly influenced by growing location.

Abstract:
The goal of this paper is to establish the dependency of the topology of a simple Lie group, specifically any of the special linear groups, on its underlying group structure. The intimate relationship between a Lie group's topology and its algebraic structure dictates some necessary topological properties, such as second countability. However, the extent to which a Lie group's topology is an "algebraic phenomenon" is, to date, still not known.

Abstract:
Formações ribeirinhas são áreas de transição entre os sistemas terrestre e aquático, caracterizadas por elevada heterogeneidade ambiental e por um amplo espectro de elementos biológicos e valores socioeconômicos. Contrário às grandes bacias hidrográficas, onde geralmente os pulsos de inundação são sazonais, os rios de pequeno porte apresentam regimes de inundação freqüentemente imprevisíveis, onde os gradientes de perturbação podem ser expressos pela razão direta entre intensidade, duração e freqüência. Considerando a distribuição de grupos ecológicos ao longo de um gradiente de inundação e as

Abstract:
The savanna woodlands of Southern Africa, colloquially termed the miombo, are poorly described in terms of biodiversity compared to other biomes. They have therefore been underrepresented in the wider understanding of how land use intensification is shaping global biodiversity. Land use change is known to reduce biodiversity and disrupt intactness of ecological communities with consequences for ecosystem functioning, resilience, and services. Miombo woodlands are described as biodiversity hotspots due to a high endemism of species and the presence of megafauna. At the same time, they are also

Abstract:
The theory of local newforms has been studied for the group of \(PGL_n\) and recently \(PGSp_4\) and some other groups of small ranks. In this dissertation, we develop a newform theory for generic supercuspidal representations of \(SO_{2n+1}\) over non-Archimedean local fields with odd characteristic by defining a family of open compact subgroup \(K(p^m)\), \(m \geq 0\) (up to conjugacy) which are analogous to the groups \(\Gamma(p^m)\) in the classical theory of modular forms. We give lower bounds on the dimension of the fixed subspaces of \(K(p^m)\) in terms of the conductor of the generic r

Abstract:
This thesis evaluated training groups for adoptive parents of special-needs children. It was hypothesized that training would influence parenting stress, stress symptoms, and marital satisfaction, and that helpfulness of training sections would depend upon the status of the participants' children (i.e., foster, adopted, or adoption in process). Data were collected from 15 participants who were sampled through agencies that typically interact with adoptive parents. Repeated measures ANOY As were computed to compare scores on the PSI/SF Parental Distress Subscale, OQ-45, and RDAS across three ti
