We investigate the ecological and evolutionary variables that best explain spatial diversity patterns of anuran amphibians in three of South America's most diverse and geographically widespread biomes: the Cerrado, Amazonia, and Atlantic Rainforest. We used Conditional Autoregressive Models to assess the potential influence of present-day climate (temperature and precipitation), historical climate

We report on the shift of energies released during Auger cascades in rare-gas ions, when the ions are not isolated but embedded in a homogeneous cluster. By combining high-resolution electron spectroscopy with multielectron coincidence spectroscopy of small Ar and Xe clusters, we investigate the dependence of Auger electron emission energies on the charge state of the emitting ion in the polarizab

We present a canonical series expansion for generalized harmonic functions in the open unit disc in the complex plane that generalizes that recently obtained for the class of (Formula presented.) -harmonic functions.

Recent advances in vibrational spectroscopy techniques have proven to be reliable, fast and operator-independent tools for extracellular vesicles (EVs) study. In an attempt to further reveal the wide potential that the vibrational spectroscopy can achieve in EV characterization, in the present study we analysed the EVs isolated from various cell lines employing Attenuated Total Reflectance Fourier

Seagrass meadows are recognized for their coastal protection services in terms of reducing the wave runup level and limiting coastal erosion. This study aims to quantify these services for a dense seagrass meadow located in a non-tidal, fetch-limited sea. A year-long field campaign was conducted to collect data on wave statistics along the cross-shore direction of the seagrass meadow, bathymetry,

The kagome lattice is an intriguing and rich platform for discovering, tuning and understanding the diverse phases of quantum matter, crucial for advancing modern and future electronics. Despite considerable efforts, accessing correlated phases at room temperature has been challenging. Using single-crystal X-ray diffraction, we discovered charge order above room temperature in La(Ru1−xFex)3Si2 (x

Fire has shaped terrestrial ecosystems for hundreds of millions of years. Human activities dramatically shift natural fire regimes, leading to adverse conservation impacts that are projected to increase in severity. Many animals appear ill-equipped to face these drastic changes, and they may be unable to adapt rapidly enough. In contrast, behavioural plasticity could offer a faster solution to ach

Seagrass meadows have been proposed as a nature-based coastal protection measure to reduce incoming wave energy. Although numerous studies have demonstrated the capability of seagrass meadows to attenuate waves, their real-world effectiveness in providing coastal protection remains uncertain. The aim of this study was to quantify the influence of a Zostera marina meadow located in a non-tidal fetc

This study focuses on the topic of the values of agile development in safety-critical cases. It is argued that a discussion exists regarding the applicability of agile methods in safety-critical development projects where researchers and developers have divergent opinions. Furthermore, another perspective called plan-driven development is shown to have connection to safety-critical development. Th

Ecotourism is a strong and upcoming branch of the traditional tourism industry. Is there a strong demand among tourists for travelling in accordance with ecological and ethical principles? This study uses an established framework for the definition of ecotourism to estimate the demand for some ecotourism criteria among visitors at the Cuyabeno Reserve in Ecuador. A survey based on the Choice Exper

The impact of education on earnings in China is primarily a quantitive analysis describing how divergence between Chinese provinces has grown in the period 1994 to 2004. The thesis is constructed around Mincerian thoughts on returns to schooling and endogenous growth theory emphasizing the crucial importance of government expenditure on knowledge capital for sustained growth. It further aims to an

This thesis examines the Swedish carbon dioxide abatement policy in the transport sector. The purpose is to investigate whether this is done in a cost-efficient way, in particular in a long-term perspective. An underlying objective is to bring thoughts on environmental concern and economic growth together. In order to do this a number of scientific reports, economic articles, and policy documents

Wikis and other web 2.0 technologies are increasingly used in business. In this sense, the overall purpose of this research was to investigate the effects of wikis on collaboration and the impact of collaboration on organizational innovation. Four interviews have been conducted with IS managers as well as regular Wiki users in different organizations to show how can wikis affect collaboration and

This thesis discusses the design and implementation of competition policy in Poland. The aim is both to analyze weather the design of competition policy in Poland corresponds to their special needs as a transition economy, and if there is a trade-off between competition policy and industry policy in Polish merger control. After the collapse of communism, the transition to a market economy required

Abstract Title: How to source from Russia? - A multiple case study of six companies’ experience of purchasing in Russia. Authors: Richard Werthén, Technology Management Johan Öhlén, Production Engineering and Management Supervisors: Christer Kedström, Dept of Business Administration Johan Lundin, Dept of Industrial Management and Logistics, Engineering Logistics Rolf Blomgren, Purchasing Manager S

Aboriginal and Torres Strait Islanders, the Indigenous peoples of Australia, inhabited this continent thousands of years before the arrival of the Europeans. Prior to the arrival of the white man the Aboriginal and Torres Strait Islanders, hereafter referred to as the Aboriginals, practiced their own culture and applied their own laws without interference from external powers. Some scientists clai
