Abstract:

<p>Det svenska kulturlandskapet har förändrats radikalt under de senaste 200 åren från ett varierat och heterogent landskap till ett mer monotont, homogeniserat landskap som följd av att olika former av mänskligt resursutnyttjande har effektiviserats. Detta har lett till en fragmentering av livsmiljöerna för flera av kulturlandskapets arter. Kraftledningsgator kan tänkas hysa naturtyper som påminner om vissa av de nu försvunna eller fragmenterade livsmiljöerna (t ex betad skogsmark och vissa typer av ängsmarker) och skulle kunna ha en viktig betydelse som reträttplats och/eller spridningskorri

Abstract:

The south-western tip of Africa holds unique levels of species richness and endemism, and contains two hotspots of biodiversity: the Cape Floristic Region and the Succulent Karoo. Several hypotheses have been proposed to explain the radiation of the region’s diverse flora. However, due to the lack of comprehensive, comparative studies, the major forces that drive plant diversification have remained unclear. My thesis combines near-complete specieslevel molecular phylogenies with detailed biological, ecological and biogeographical information to investigate the evolutionary processes generating

Groundwater (GW) -fed streams are a common feature of paraglacial floodplains and are regarded as ‘biodiversity hotspots’, due to their role as valuable aquatic habitats.

To address this significant knowledge gap site specific research was conducted on GW-fed streams within Denali National Park & Preserve, Alaska, during 2013 and 2014.

Myers first identified the world’s 25 biodiversity hotspots and pioneered innovative ideas about the usefulness of biodiversity models for establishing long-term resource conservation strategies at global scales. Since Myers, most of the subsequent studies using hotspot science for biodiversity modeling have used large spatial scales like countries, provinces or states, and other biogeoraphic regions. The California Floristic Province continues to be one of the recognized global biodiversity hotspots. Our study site, San Luis Obispo County is within this hotspot and we created a map of plan

South Africa is a megadiverse country, and its biodiversity is endangered by population pressure and the development needs of a developing country. In order to address the rapid decline in biological diversity, biodiversity planning has become a key focus area that aims at identifying priority areas for species and ecosystem conservation within and outside of formally protected areas. Plant conservation hotspots are identified by the quantification of indicator taxa such as plant taxa richness, rarity and endemism.

Natural rubber is in high demand for the manufacture of tyres, and rubber plantations are expanding globally. Southeast Asia is the epicentre of rubber cultivation, where deforestation to make way for rubber has been occurring for decades. This process has caused substantial biodiversity loss and carbon emissions. Expansion has recently shifted northwards into mainland Southeast Asia (the Indo-Burma biodiversity hotspot) due to the development of hardier rubber varieties that can survive longer dry seasons and cooler climates.

Given inadequate budgets with which to stem the rapid destruction of biodiversity, conservationists must set clear priorities for action.

Abstract:

Habitat loss and fragmentation and human-wildlife conflicts, often resulting in retaliatory killing in response to livestock predation, are one of the main threats to wild felids worldwide, including pumas (Puma concolor). However, mesocarnivores are more abundant than large carnivores, live closer to human settlements, and drive community structure and processes in similar or different ways from large predators. Understanding both large and small carnivores' habitat use is key to their conservation and management. Thus, there is need to explore the ecological roles of predators (including inv

Abstract:

Seed dispersal mutualisms are important ecological interactions that can shape plant communities by influencing species distributions, community composition, and the regeneration of populations following a disturbance. Considering the fundamental role seed dispersal mutualisms play in many plant communities, it is important to understand, both generally and for individual seed dispersal mutualisms, what determines when animal partners successfully disperse seeds and when they do not. Myrmecochory, the dispersal of seeds by ants, is the most common form of zoochory in Western Australia. Myrmeco

Abstract:

The thesis of Kit Prendergast addressed impacts of urbanisation and introduced honeybees on native bees in southwest Australia. Additionally, efficacy of bee survey methods were evaluated. The study found remnant bushland, with high proportions of native flora, was of greater importance for supporting native bee populations, species, and pollinator networks, compared with residential gardens. Honeybees occupied distinct positions in pollinator networks, and altered network properties, with context-dependent impacts on native bees.

Thesis (MSc)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: The present global biodiversity crisis is characterized mostly by loss of species due to habitat destruction but there other major threats – notably invasive alien species. The term “biodiversity hotspot” has been coined to emphasize areas for conservation prioritization – areas that have high biodiversity under threat from habitat destruction, invasive species, etc. The Cape Floristic Region (CFR) in the Western Cape (WC) Province of South Africa has the highest biodiversity of all Mediterranean-type climate regions global

Thesis (PhD)--Stellenbosch University, 2011.<br>ENGLISH ABSTRACT: Both taxonomic diversity and diversity of species interaction networks are experiencing declines as a result of agricultural intensification at habitat and landscape scales. Reversing this trend is a key conservation issue, particularly for important functional groups such as flower-visiting insects and the networks within which they interact. This is of great concern in regions of high conservation priority such as the Cape Floristic Region (CFR), known for its high level of floral and faunal endemism and exceptional speci

Abstract:

Many regions around the world are renowned as biodiversity hotspots. South Western Australia is one of these. A combination of the recognised high biodiversity and a seemingly unbalanced species distribution of the genus Nunciella across Australia initiated the investigation into the diversity of the south western species of Nunciella. Previous descriptions indicate two of the 11 Nunciella species are found in this region, one of these with a very large recorded distribution in contradiction to the short range distribution of all the other species. Through observations of museum specimens it i

Abstract:

Em diversos estudos ao redor do globo, a estrutura e heterogeneidade da vegetação têm se mostrado um fator determinante na diversidade de espécies de aves e também de outros grupos de animais. O Cerrado é o segundo mais extenso e mais ameaçado bioma de ocorrência no Brasil. Este bioma também é caracterizado por um evidente gradiente ambiental de estrutura e heterogeneidade de vegetação. Na presente tese analisamos a influência da estrutura e heterogeneidade da vegetação sobre a diversidade em comunidades de aves do Cerrado. Nossa expectativa era corroborar a “Hipótese de Heterogeneidade

Neste trabalho realizou-se o estudo de distribuição, riqueza e conservação do gênero Davilla Vand. (Dilleniaceae) no Neotrópico. Para tal utilizou-se a modelagem de distribuição de espécies com o algoritmo Maxent. Este produz distribuição das espécies no espaço geográfico a partir de dados ambiental e de ocorrência. Foram estudadas as espécies de acordo com o bioma de ocorrência: Mata Atlântica; Cerrado; e Amazônia. Este grupo está representado no Neotrópico por 25 espécies. Para o Cerrado incluiu-se além das espécies do gênero Davilla as demais espécies da família Dilleniaceae. Os resultados
