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 …

Mapping Plant Biodiversity Hotspots at the County Scale: A New Tool for Establishing Resource Conservation Strategies
<p>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 …

An ecological and conservation planning study of the plant biodiversity on natural and semi-natural remnants on the Cape Flats, South Africa
The Cape Flats (Western Cape Province, South Africa) is situated on the low-lying sandy plain immediately adjacent to the Cape Peninsula, and is part of the mediterranean-climate Cape Floristic Region. Fire-dependant Sand Plain Fynbos, Strandveld and West Coast Renosterveld exist on natural and …

The Influence of Plant Diversity on Soil Physical Properties in Grasslands.
The scale of biodiversity loss facing our planet has prompted many scientists to explore the potential consequences for ecosystems, and the goods and services that they provide. A favoured approach for investigating such impacts of species loss is to experimentally address the result of a reduction …

The Effects of Invasive Plants on Biodiversity Across Spatial Scales
<p>Although introduced plant species are often considered to be 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 …

Biodiversity-ecosystem service relationships in degraded and recovering ecosystems.
Biodiversity loss is occurring at an unprecedented rate and most of this loss is due to human induced pressure. This loss in biodiversity had led to concerns that the provision of ecosystem services that humans depend upon might be negatively affected. As such much modern conservation science …

A Floristic Study of the Cal Poly Swanton Pacific Ranch and a New Combination in Sanicula crassicaulis (Apiaceae), Sanicula crassicaulis var. Nudicaulis
<p>Globally we are experiencing a biodiversity crisis and potentially a sixth mass extinction event. Plant specimens are one of the best, most concrete records of biodiversity that we can create. Despite this, the rate of plant collecting has declined steeply since World War II. Now more than ever, …
