m -Cresol methylation: Role of internal and external acid sites in the product distribution
(Elsevier Science, 2017-03)
The effect of the porous structure and the role of internal and external acid sites in product distribution in gas-phase alkylation of m-cresol with methanol were studied on zeolites HBEA, HZSM5 and HMCM22. Catalysts were ...
Improving methods in gap ecology: Revisiting size and shape distributions using a model selection approach
(2013-05-01)
Questions: We assess gap size and shape distributions, two important descriptors of the forest disturbance regime, by asking: which statistical model best describes gap size distribution; can simple geometric forms adequately ...

Patterns of cranial shape diversification during the phylogenetic branching process of New World monkeys (Primates: Platyrrhini)
(Wiley Blackwell Publishing, Inc, 2011-08)
One of the central topics in evolutionary biology is understanding the processes responsible for phenotypic diversification related to ecological factors. New World monkeys are an excellent reference system to investigate ...
Sexual differences in locomotor performance in Tropidurus catalanensis lizards (Squamata: Tropiduridae) – body shape, size and limb musculature explain variation between males and females
(Wiley, 2015-12)
Sexual dimorphism (SD) is the evolutionary outcome of selection acting differently on males and females. Several studies describe sexual differences in body size, although other morphological traits might be allometric ...
Gender classification based on fusion of different spatial scale features selected by mutual information from histogram of lbp, intensity, and shape
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2013)
In this paper, we report our extension of the use of feature selection based on mutual information and feature fusion to improve gender classification of face images. We compare the results of fusing three groups of features, ...
Gender Classification Based on Fusion of Different Spatial Scale Features Selected by Mutual Information From Histogram of LBP, Intensity, and Shape
(SPRINGER, 2013-06-12)
In this paper, we report our extension of the use of
feature selection based on mutual information and feature fusion
to improve gender classification of face images. We compare the
results of fusing three groups of ...
Using visual cues of microhabitat traits to find home: the case study of a bromeliad-living jumping spider (Salticidae)
(Oxford University Press, 2010-07-01)
There are many examples of predators having specialized microhabitat requirements, but the sensory mechanisms by which predators detect, identify, and evaluate microhabitats are only poorly understood. The ability to use ...
Is variation in flower shape and length among native and non-native populations of Nicotiana glauca a product of pollinator-mediated selection?
(Springer, 2020-09)
Due to drastic changes in pollinators between native and invaded habitats, we might expect that pollinator-mediated selection on floral traits of alien plants differ from that in their native ranges. Here, through geometric ...
