Grossi Córdova, Bruno; Veloso Iriarte, Claudio; Taucare Ríos, Andrés; Canals Lambarri, Mauricio (Amer Arachnological Soc, 2016)Although sexual size dimorphism is a widely observed phenomenon in nature, the selective forces that led to it are still controversial. Here we study sexual dimorphism in the static allometry of the legs of a large ground ...

Canals Lambarri, Mauricio (Sociedad Médica de Santiago, 2010-08-02)In order to increase awareness of the pandemic and to streamline control measures before any new outbreak of infl uenza we analyze the behavior of the cases of Chile and from 9 countries with more cases in 2009. Reproductive ...

Grossi, Bruno; Loncomilla, Patricio; Canals Lambarri, Mauricio; Ruiz del Solar, Javier (Universidad de la Frontera, 2019)Determining kinematics of hindlimbs of theropod dinosaurs has been a challenge. Since cursorial birds are phylogenetically closest to theropod dinosaurs they are commonly used as a kinematic model of theropod dinosaur ...

Grossi, Bruno; Canals Lambarri, Mauricio (WILEY-LISS, DIV JOHN WILEY & SONS INC, 2010-03-08)We analyzed the morphology and the walk–trot and trot–gallop transition velocities of nine juvenile horses and compared them with their mothers. We also compared the relative stride length and the duty factor of the ...

Alfaro, Carmen; Figueroa Pérez, Daniela; Sabat Kirkwood, Alejandro Pablo; Sallaberry Ayerza, Michel; Canals Lambarri, Mauricio (SOC CHILENA ANATOMIA, 2009-12-12)We studied the respiratory surface density and the thickness of the air-blood barrier in the Picui Ground Dove (Columbina picui), and compared it with Eared Dove (Zenaida auriculata) and Blacked-winged Ground Dove (Metropelia ...

Grossi, Bruno; Solís Muñoz, Rigoberto; Veloso Iriarte, Claudio; Canals Lambarri, Mauricio (Wiley, 2016)Most male spiders are smaller than females; during sexual maturity, males change their behaviour, abandoning their web or nest to seek out receptive females actively, whereas females stalk prey near their web or nest and ...

Torres Contreras, Hugo; Canals Lambarri, Mauricio (SPRINGER/PLENUM PUBLISHERS, 2010-05-01)Animals display foraging trajectories when exploiting food patches. These displacements have been studied, particularly in organisms that forage from a central place. The complexity of a movement path may be analyzed by ...

Canals Lambarri, Mauricio; Figueroa, D. P.; Miranda, J. P.; Sabat Kirkwood, Alejandro Pablo (2009)1.In the altricial rodent, Phyllotis darwini, we found higher body temperatures and faster developmental rates of the thermoregulatory capacity in neonates born from cold- than warm-acclimated mothers.2.This difference ...

Alfaro, Carmen; Figueroa, Daniela P.; Torres Contreras, Hugo; Veloso Iriarte, Claudio; Venegas, Fanny; Canals Lambarri, Mauricio; Canals, Lucía (2013)Variations in the preferred temperatures during the rest periods of Grammostola rosea Walckenaer and Paraphysa parvula Pocock, two mygalomorph spiders occupying different habitats in central Chile, are analyzed. The ...

Canals Lambarri, Mauricio; Figueroa, D.; Alfaro, C.; Kawamoto, T.; Torres Contreras, Hugo; Sabat Kirkwood, Alejandro Pablo; Veloso Iriarte, Claudio (2011)The metabolic and water evaporation strategies in spiders may be part of a set of physiological adaptations to tolerate low or unpredictable food availability, buffering spiders against environmental fluctuations such as ...

Thienel de La Fuente, Mariana; Canals Lambarri, Mauricio; Bozinovic, Francisco; Veloso Iriarte, Claudio (Elsevier, 2015)Insects exhibit three patterns of gas exchange: continuous (CoGE), cyclic (CGE) and discontinuous (DGE). In this work, we present the first record of a DGE in Phasmatodea and its transition to CGE and to CoGE through a ...

Gutstein, Carolina S.; Figueroa Bravo, Constanza P.; Pyenson, Nicholas D.; Yury Yáñez, Roberto E.; Canals Lambarri, Mauricio; Cozzuol, Mario A. (Elsevier, 2014)This study compares the bony ear morphology of freshwater and marine odontocetes (toothed whales). Odontocetes are unique among marine mammals in two important respects: 1) they use echolocation; 2) at least three lineages ...

Osmoregulation and adaptive radiation in the ovenbird genus Cinclodes (Passeriformes : Furnariidae) Sabat Kirkwood, Alejandro Pablo; Maldonado, Karin; Canals Lambarri, Mauricio; Martínez del Río, Carlos (BLACKWELL, 2006-10)1. The genus Cinclodes is unique among passerines because it includes two species that can be considered marine/coastal and also includes several species that inhabit freshwater streams or that shift habitats between ...

Figueroa, D. P.; Sabat Kirkwood, Alejandro Pablo; Torres Contreras, Hugo; Veloso Iriarte, Claudio; Canals Lambarri, Mauricio (PERGAMON-ELSEVIER SCIENCE LTD, 2010-01-01)Small animals need efficient water conservation mechanisms for survival and reproduction, which is relevant for the spiders that have large book lungs with large respiratory surface. If lung evaporation is relevant to ...

Percolation of influenza AH1N1 epidemic in the world: Usefulness of the spatial-connectivity models Canals Cifuentes, Andrea; Canals Lambarri, Mauricio (SOC. MEDICA SANTIAGO, 2010-03-31)The 2009 AH1N1 epidemics expanded rapidly around the world by the current connectivity conditions. The spread of epidemics can be described by the phenomenon of percolation, that allows the estimation of the threshold ...
-
Canals Lambarri, Mauricio (2010-04)Influenza AH1N1 severely affected the population of Chile. It has high transmissibility, which may stress the health system capacity. An adequate prediction of number of cases and frequency of complications is needed. ...

Canals Lambarri, Mauricio; Sabat Kirkwood, Alejandro Pablo; Veloso Iriarte, Claudio (SPRINGER HEIDELBERG, 2008-03)The bronchial tree of most mammalian lungs is a good example of an efficient distribution system whose geometry and dimensions of branched structures are important factors in determining the efficiency of respiration. Small ...

Canals Lambarri, Mauricio; Olivares Pérez-Montt, Ricardo; Rosenmann Abramovich, Mario (SOCIEDAD BIOLGIA CHILE, 2005)In this paper we develop a method to estimate lung Volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: ...
