A short history of the phosphorus index and Andrew Sharpley's contributions from inception through development and implementation

Journal of Environmental Quality, EarlyView.
Abstract In the 1980s, growing recognition of agricultural phosphorus (P) sources to surface water eutrophication led to scrutiny of animal feeding operations. In 1990, the USDA‐Natural Resources Conservation Service (NRCS) invited prominent scientists to find a solution. It was at an initial meeting that Dr. Andrew Sharpley suggested that P assessment

Jumping spider (Araneae: Salticidae) diversity in the understory of the Argentinian Atlantic Forest

Caldasia, 2017
The Atlantic Forest is one of the key biodiversity hotspots in the world. Its understory can be dominated by species such as the native bamboo Chusquea ramosissima (tacuarembó), which can be an aggressive gap colonizer and change biotic and abiotic ...

Tracking insect outbreaks: a case study of community-assisted moth monitoring using sex pheromone traps

FACETS, 2020
Insect outbreaks can cover vast geographic areas making it onerous to cost-effectively monitor populations to address management or ecological questions.

A multi‐proxy record of climate variability during the Loch Lomond Stadial (GS‐1) at Old Buckenham Mere, East England, UK

Journal of Quaternary Science, EarlyView.
ABSTRACT Northwest Europe experienced high‐amplitude climate change at the onset and end of the Younger Dryas (YD; ca 12 800–11 600 cal a BP), a crucial period to develop our understanding of natural climate dynamics. European palaeoclimatological records generally suggest a bipartite structure of the YD, potentially due to a northward retreat of the ...

Compilation of woody species occurring in the Brazilian Atlantic Forest complex

Frontiers of Biogeography, 2015
The Atlantic Forest is a hotspot for biodiversity conservation because of its high levels of endemism and threatened areas. Three main forest types, differentiated by their floras, compose the Atlantic Forest: ‘Atlantic Forest’ sensu strictu, ‘Araucaria ...

Deep ocean early warning signals of an Atlantic MOC collapse [PDF]

, 2014
The Atlantic Meridional Overturning Circulation (MOC) is a crucial part of the climate system because of its associated northward heat transport. The present-day MOC is sensitive to freshwater anomalies and may collapse to a state with a strongly reduced northward heat transport.

At the far end of everything: A likely Ahrensburgian presence in the far north of the Isle of Skye, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT A Late Upper Paleolithic (LUP) site containing Ahrensburgian‐type stone tools has been discovered at South Cuidrach, Isle of Skye, Scotland. Together with a group of intertidal stone circular alignments also recently discovered on the island, this new evidence for the occupation of northern Scotland also represents the most northerly LUP site ...

Legal boundaries and conservation: The case of Seasonally Dry Forests of the Serra da Bodoquena National Park, Brazil

Acta Botânica Brasílica
The Serra da Bodoquena National Park is an important protected area that promotes the conservation of a threatened ecosystem, the Dry Forest. It comprises two major fragments of predominantly Seasonally Dry Forest vegetation.

An objective change point analysis of landfalling historical Atlantic hurricane numbers [PDF]

arXiv, 2006
In previous work we have analysed the Atlantic basin hurricane number time-series to identify decadal time-scale change points. We now repeat the analysis but for US landfalling hurricanes. The results are very different.
