Architecture of the global land acquisition system: applying the tools of network science to identify key vulnerabilities

Global land acquisitions, often dubbed 'land grabbing' are increasingly becoming drivers of land change. We use the tools of network science to describe the connectivity of the global acquisition system. We find that 126 countries participate in this form of global land trade. Importers are concentrated in the Global North, the emerging economies of Asia, and the Middle East, while exporters are c

Genetic diversity of avian blood parasites in SE Europe: Cytochrome b lineages of the genera Plasmodium and Haemoproteus (Haemosporida) from Bulgaria

We used a nested PCR protocol to examine the genetic diversity of cytochrome b (cyt b) lineages from blood parasites of the genera Plasmodium and Haemoproteus in birds in Bulgaria. In total, 460 birds of 43 species and 14 families (mostly passerines) were examined for the presence of infections. Of them, 267 were recognised as infected with haemosporidian parasites. Mixed infections were recorded

Phosphorus in soil treatment systems : accumulation and mobility

Septic tanks with subsequent soil treatment systems (STS) are a common treatment technique for domestic wastewater in rural areas. Phosphorus (P) leakage from such systems may pose a risk to water quality (especially if they are located relatively close to surface waters). In this study, six STS in Sweden (11-28 years old) were examined. Samples taken from the unsaturated subsoil beneath the distr

Migrant Workers as Subjects of Human Rights

Den här uppsatsen syftar till att undersöka hur migrantarbetares rättigheter är skyddade inom folkrätt och mänskliga rättigheter. Efter en kort introduktion till internationell migration som fenomen samt de relevanta folkrättsliga normerna övergår uppsatsen till att behandla utlänningars ställning inom mänskliga rättigheter, genom en undersökning av tre av FN:s konventioner för mänskliga rättighetThis thesis examines the international protection of migrant workers. After a brief description of the migration phenomenon and the corresponding international legal framework, the position of aliens under human rights law is addressed through a review of three human rights conventions adopted within the framework of the United Nations. Following that, focus is turned to the international conventi

Changes in waterbird occurrence and abundance at their northern range boundaries in response to climate warming : importance of site area and protection status

Climate warming is driving changes in species distribution, but habitat characteristics can interact with warming temperatures to affect populations in unexpected ways. We investigated wintering waterbird responses to climate warming depending on habitat characteristics, with a focus on the northern boundary of their non-breeding distributions where winter climatic conditions are more extreme. At

Do standard weather conditions and flower density affect the results of butterfly monitoring schemes? A field test in three bio-geographic regions in Europe

Butterflies and moths have often been suggested as suitable indicators for monitoring environmental effects on biodiversity, land use changes and management practices, and many butterfly monitoring schemes are established and run in Europe. In these monitoring programmes, the field counts are only carried out when certain, standard weather conditions considered favourable for butterflies are met.

The dead can talk : Investigating trace element and organic pollutant exposure in mammalian roadkill under contrasting habitats

Urban environments are exposed to a substantial range of anthropic pressures, including chemical exposure. While trace metals and legacy pollutants have been well documented, the extent of wildlife exposure to emerging contaminants has received little attention, in terrestrial mammals. Concentrations of trace elements (Ag, Al, As, Cd, Co, Cr, Cu, Fe, Mn, Pb and Zn) and 48 organic pollutants (Polyc

Incorporating microbiome analyses can enhance conservation of threatened species and ecosystem functions

Conservation genomics is a rapidly growing subdiscipline of conservation biology that uses genome-wide information to inform management of biodiversity at all levels. Such efforts typically focus on species or systems of conservation interest, but rarely consider associated microbes. At least three major approaches have been used to study how microorganisms broadly contribute to conservation areas

Interactions between climate warming and management actions determining bird community change in protected areas

Biodiversity is increasingly negatively affected by climate warming, making this issue a major conservation concern. Many bird species respond to warming temperatures by shifting distribution ranges, but these shifts often lag behind temperature changes. Protected areas (PAs) can facilitate such shifts, but a growing body of literature suggests that not all PAs facilitate climate warming responses

BioTIME 2.0: Expanding and Improving a Database of Biodiversity Time Series

Motivation: Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreo

ReSurveyEurope: A database of resurveyed vegetation plots in Europe

Aims: We introduce ReSurveyEurope — a new data source of resurveyed vegetation plots in Europe, compiled by a collaborative network of vegetation scientists. We de-scribe the scope of this initiative, provide an overview of currently available data, governance, data contribution rules, and accessibility. In addition, we outline further steps, including potential research questions. Results: ReSurv

Artificial intelligence

Artificial intelligence (AI) is increasingly being discussed at the international level, with a particular focus on its potential to help achieve the Sustainable Development Goals (SDGs). The Global Digital Compact, adopted at the Summit of the Future, calls for the establishment of international institutions to govern AI technologies. The impact of AI on sustainable development is a multifaceted

Youth

Youth are one of the nine major groups of civil society for sustainable development formalized by Agenda 21. The Major Group of Children and Youth is an active independent mechanism facilitating youth involvement in the United Nations system. Youth representatives from various organizations increasingly engage in global sustainability politics but face challenges such as financial constraints, tok

Essential Concepts for Implementing the Sustainable Development Goals : An Introduction

This A-Z Guide offers an accessible and user-friendly overview of the essential concepts and terms needed to understand the implementation of the SDGs. Crafted in the form of an encyclopaedia, the volume presents 105 entries on important concepts and terms and their links to academic and policy debates. Each entry offers basic definitions of the concept or term at issue, followed by a brief discus

Global synthesis of apple pollination research highlights general pollen limitation and positive contributions of wild bees compared to honeybees

Apple is one of the most important pollinator-dependent fruit crops worldwide. To secure high-quality yields, it is crucial to know which, and to what extent, pollinating insects contribute to its pollination success as measured by fruit set, fruit weight and seed set. We perform a meta-analysis of field studies conducted across multiple orchards on insect-mediated pollination in apple cultivation

A trait spectrum linking nitrogen acquisition and carbon use of ectomycorrhizal fungi

Trait spectra have been used in various branches of ecology to explain and predict patterns of species distributions. Several categorical and continuous traits have been proposed as relevant for ectomycorrhizal fungi, but a spectrum that unifies co-varying traits remains to be established and tested. Here, we propose a nitrogen acquisition and carbon use trait spectrum for ectomycorrhizal fungi in

Taking advantage of open data in coastal science and conservation

Human society relies on, and interacts with, a diverse assortment of organisms and ecological systems, from the local to the global level. Research and management of these coupled social-ecological systems requires data that speaks to the variety of processes, statuses, and situations defined by them. Effective stewardship is enhanced by interdisciplinary thinking and, critically, access to intero
