Predicting biodiversity loss in insular neotropical forest habitat patches
… forests have experienced high rates of biodiversity loss as a result of burgeoning land-use changes. Habitat conversion into cropland, pastures, and more recently hydroelectric lakes, are leading drivers of forest loss and fragmentation of pristine forests in the world’s most biodiverse …

Using Machine Learning Techniques on Satellite Data to Predict the Effect of Urbanization on Avian Biodiversity
… conditions of an urban area and local urban biodiversity loss is integral to informing policy decisions, urban design, and community action plans. Though some previous research explores the relationship between urban areas and biodiversity loss, the limited available studies are often …

The Nexus of Climate Change, Biodiversity, and Food Security: A Brazil Case Study
… not the only result of modern food production, biodiversity loss is as well. According to a recent study by Chatham House, because of policies used to achieve current food production and prices, agriculture now “depends heavily on the use of inputs such as fertilizer, pesticides, energy, land …

Including biodiversity conservation in climate change decision making
… challenges of our time are climate change and biodiversity conservation. According to the Intergovernmental Panel on Climate Change (IPCC), bioenergy is expected to play a major role as a mitigation strategy for climate change. The projected scale of the deployment of bioenergy is big, …

The Effects of Invasive Plants on Biodiversity Across Spatial Scales
… one of the most notable anthropogenic threats to biodiversity, their influence on biodiversity remains controversial. Some studies have shown large declines in biodiversity in plant-invaded areas, whereas others have noted that plant invasions are rarely implicated as the cause of species …

Biodiversity Impact of China's Power System Transition From a Life Cycle Perspective
Biodiversity loss is a critical but underexplored dimension of global low-carbon energy transitions, particularly in the context of China’s power sector. China’s power sector is undergoing an in-depth decarbonization, which could shape both the local and global environment. To uncover the …

Denitrification response to nutrient enrichment in New Zealand estuaries
… to estuaries through mitigating eutrophication. Biodiversity loss and increased mud content are important indicators of estuarine ecosystem degradation, and have been associated with negative effects on soft-sediment ecosystem functioning. However, the impact of these stressors on ecosystem …

BUILDING FRAMEWORKS FOR UNDERSTANDING INVASIONS AND EXTINCTIONS FOR BIODIVERSITY SCIENCE
… in mechanisms that increase and decrease biodiversity on Earth and the effects they have on organisms’ interactions and functions. Global biodiversity loss is now outstripping accumulation and far exceeds expected background levels and has drawn comparisons to previous mass extinctions. …

Increased phenotypic plasticity linked to broader geographic range size in sunflower (Helianthus) species
Human activity worsens global biodiversity loss, particularly for vulnerable rare species. Plant species can respond to environmental changes via adaptation and/or acclimation or migration, yet limited genetic diversity and fitness in rare species can hinder these processes. Changes in light …

Carbon Dynamics in Extracted Minerotrophic Peatlands: An Analysis of the Effect of Plant Biodiversity
Recent experiments have shown that biodiversity loss can impair natural ecosystem functioning. Extraction of horticultural peat is known to alter the diversity of vegetation and convert peatlands from net sinks to persistent sources of carbon to the atmosphere. Peatland restoration has been shown …

A Qualitative Study of Urban Mini-forest Initiation Within the Context of Canada’s Changing Climate
… prior environmental experience, concerns about biodiversity loss, anticipation of outcomes, opportunities for community engagement, and community empowerment were common factors. For some, opportunities for reconciliation with Indigenous People were identified as a fundamental factor in …

Demographic and genetic variability in Cape Dwarf Chameleons, Bradypodion pumilum, withink a fragmented, urban habitat
… is recognized as a primary cause of biodiversity loss. To maximize biodiversity maintenance, researchers in the field of conservation biology often investigate population demography and genetic variability for species inhabiting fragmented landscapes. Findings from such work enable …

From genes to species: Characterizing spatial and temporal variation in frog and toad multidimensional biodiversity
Biodiversity is a complex concept encapsulating the variation that occurs within and among levels of biological organization. It is positively linked to ecosystem persistence, adaptability, and function. Biodiversity loss, driven by global change and human activities, is one of the most prominent …

An Alternate Approach to Ecosystem Mapping: Fusing Orthophotography with LANDSAT ETM+ Data for a Object-Based Classification, South Eastern Arkansas.
… has become an important means to preventing biodiversity loss. A limitation in indentifying and quantifying ecosystems is the cost of obtaining high resolution imagery necessary for a high resolution land cover assessment. This research shows how free, different resolution imagery …

Essays on Nature-Related Risk Premia in Equity Markets [before doctoral defense]
Biodiversity loss has emerged as a critical challenge for the global economy and financial systems. The IPBES Global Assessment (IPBES, 2019) reports that 75% of the land surface is significantly altered and 66% of the ocean area is experiencing increasing cumulative impacts. Over USD 44 trillion …
