A landscape genomics approach to understanding and predicting species distribution

In habitat modelling, an initial step is to define geoenvironmental variables to be included in a predictive model. According to Guisan and Zimmermann (2000), the selection of predictors can be made either arbitrarily, automatically by stepwise procedures, ...

Quantifying the taxonomic diversity in real species communities

Cécile Caretta Cartozo, Marc Barthélemy

We analyze several florae (collections of plant species populating specific areas) in different geographic and climatic regions. For every list of species we produce a taxonomic classification tree and we consider its statistical properties. We find that r ...

Cross-species and cross-platform gene expression studies with the Bioconductor-compliant R package 'annotationTools'

Mauro Delorenzi

BACKGROUND: The variety of DNA microarray formats and datasets presently available offers an unprecedented opportunity to perform insightful comparisons of heterogeneous data. Cross-species studies, in particular, have the power of identifying conserved, f ...

Evaluation of carrier ampholyte-based capillary electrophoresis for separation of

Carrier ampholyte-based capillary electrophoresis (CABCE) has recently been introduced as an alternative to CE (CZE) in the classical buffers. In this study, isoelectric BGEs were obtained by fractionation of Servalyt pH 4-9 carrier ampholytes to cuts of t ...

Evolutionary Conditions for the Emergence of Communication in Robots

Dario Floreano, Stéphane Magnenat, Laurent Keller, Sara Mitri

Information transfer plays a central role in the biology of most organisms, particularly social species [1, 2]. Although the neurophysiological processes by which signals are produced, conducted, perceived, and interpreted are well understood, the conditio ...

Conserved oviposition preferences in alpine leaf beetle populations despite host shifts and isolation

Anthony Christopher Davison

Choosing the plant on which to lay their eggs is the last act of care that most female herbivorous insects bestow upon their offspring. These decisions play a pivotal role in insect–plant interactions, placing host preference under strong selection and ...

The rise and fall of Hox gene clusters

Denis Duboule

Although all bilaterian animals have a related set of Hox genes, the genomic organization of this gene complement comes in different flavors. In some unrelated species, Hox genes are clustered; in others, they are not. This indicates that the bilaterian an ...

Adaptive visual attention model

Heinz Hügli, Alexandre Bur

Visual attention, defined as the ability of a biological or artificial vision system to rapidly detect potentially relevant parts of a visual scene, provides a general purpose solution for low level feature detection in a vision architecture. Well consider ...

Competitive effects of herbaceous vegetation on tree seedling emergence, growth and survival: does gap size matter?

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

Question: What is the effect of gap size on the seedling emergence, growth and survival of four common tree species in wooded pastures? Location: A pasture in the Jura mountains, Switzerland. Methods: Seeds were sown in a complete three-way factorial desig ...

Glasslike structure of globular proteins and the boson peak

Paolo De Los Rios, Francesco Piazza

Vibrational spectra of proteins and topologically disordered solids display a common anomaly at low frequencies, known as boson peak. We show that such feature in globular proteins can be deciphered in terms of an energy landscape picture, as it is for gla ...
