LSCorridors: Landscape ecology, ecological corridors and Cloud computing

 

LSCorridors

LSCorridors is a free package designed to model possible dispersal routes of the species among resource patches and multiple routes of ecological functional corridors. The software can deal will very large data and can manage very complex simulations. The LSCorridors is powereed by Microsoft Azure Cloud Computing for Research.

Assessing biodiversity threats in Brazil throughout Azure Cloud computing

Assessing  biodiversityAtlantic Forest and Cerrado are the two biomes of São State and both recognized as biodiversity hotspots, due to its high biodiversity and the threats they suffer. The key landscape structure that best explain biodiversity distribution are: spatial arrangement of fragments, edge effect, connectivity, degree of isolation. As deal with very large datasets are highly time demanding, we are using powerful virtual machines (VM) granted by the Microsoft Azure Cloud Computing for Research on the highly complex computational processing.

Amazon endemic trees under climate changes

Amazon endemicClimatic metrics can be good predictors of changes in biodiversity and this can severely impact the majority of endemic species in regions like Amazon. We predicted Amazon threat status in response to climate change for 21 century and evaluated whether climate velocities are as good surrogates to predict biodiversity change as are the climate trajectories. We found that climate trajectories are good predictors for tree´s biodiversity changes. Climate metrics should be good surrogates for changes in biodiversity, although, for a species point of view this association should be valid only for that species that can keep pace with climate change velocity.

Resampling techniques applied to data analysis of biodiversity in Atlantic Forest

Resampling techniquesResearch conducted by Universidade Estadual Paulista Julio de Mesquita Filho (UNESP, Rio Claro, Brazil, and Texas Tech University, project funded by FAPESP and CNPq) involving ecological modelling to understand multiscalebat community responses to landscape degradation. We built non-linear mixed models and resampled it 10,000 times using bootstrap technique in order to get model selection frequencies and best evaluation of null models. This wasvery time consuming and was achieved using Microsoft Azure machines, important tools to conclude tasks underlying large datasets.

Cloud computing for modelling ecological corridors

jusilveira_msr_eng_2014_07Ecological corridor has been used as an important strategy for biodiversity maintenance worldwide. Research conducted by São Paulo State University (UNESP, Rio Claro, Brazil) scientists has used highly complex computational processing in the clouds provided by Microsoft Research & FAPESP, in order to assess the best strategies to design ecological corridors for Brazilian Atlantic Forest and Cerrado biodiversity hotspots.

LEEC – Spatial Ecology and Conservation Lab

The Spatial Ecology and Conservation Lab (LEEC) aims to incorporate explicitly the spatial arrangement of elements (individuals, species occurrence, types of environments, plant remnants) to understand patterns of biodiversity and guide conservation actions and restoration. We consider of fundamental importance to handle multiple, and functional aspects of the ecosystem. We are interested in understanding from the organization of individuals and species to metacommunity, covering local, regional and continental scales.

LEEC is envolved with a wide range of issues within landscape ecology. Here are our main research topics.  Continue reading
