"There is a great connection between the rain forest, biodiversity and space," he said.
These are the farmers who plant dozens of different crops in fields that resemble quilts and practice long and elaborate rotations, thereby achieving the rich biodiversity in space and time that is the key to making a farm sustainable.
To design robust protected area networks, accurately measure species losses, or understand the processes that maintain species diversity, conservation science must consider the organization of biodiversity in space.
Because specimens and all associated data are both georeferenced and time-stamped, they provide critical resources for examination of changes in biodiversity over space and time (Johnson et al. 2012; Lister 2011; Wandeler et al. 2007).
Beta-diversity describes the change in biodiversity over space, time, or environmental gradients and often provides ecological and evolutionary information on dispersal, speciation processes, and species turnover.
In the absence of an accepted scientific indicator system, the EU's Green Capital programme at least has a rigorous shortlisting process based on a technical assessment covering aspects such as biodiversity, green spaces and how a city deals with wastewater, noise and air quality.
They increase biodiversity and create space for trees and plants to grow, but can cause damage to crops and gardens.
In "The Curse of Factory Farms" (editorial, Aug. 30), you talk about the public's desire for "open space, biodiversity and clean, non-malodorous air".
And it should never use taxpayer money to encourage a method of farming that works against the public's desire for open space, biodiversity and clean, non-malodorous air.
Soil biodiversity varies through space as influenced by habitat features and land-use history.
