(Frontiers Media S.A., 2015)Spiders are small arthropods that have colonized terrestrial environments. These impose three main problems: (i) terrestrial habitats have large fluctuations in temperature and humidity; (ii) the internal concentration of ...
-
(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 ...
-
(NLM (Medline), 2018)Copyright © 2018 Campbell et al. For insects that depend on one or more bacterial endosymbionts for survival, it is critical that these bacteria are faithfully transmitted between insect generations. Cicadas harbor two ...
-
(2012)We characterize, in both the laboratory and the field, the preferential thermal microenvironments of Paraphysa parvula (Pocock 1903) (Araneae: Theraphosidae), a mygalomorph spider that successfully inhabits the high elevation ...
-
(Elsevier, 2018-05)Two strategies have been described for cold tolerance in arthropods: (1) freeze-tolerant organisms, which can survive the formation of ice crystals and (2) freeze-avoidant organisms, which prevent the ice crystal formation ...
-
(Elsevier, 2017)In this article, we assessed the effect of the rearing temperature on life history traits of the poorly known fly Phasmovora phasmophagae (Diptera: Tachinidae), a parasitoid of Agathemera crassa (Phasmatodea: Agathemeridae) ...
-
(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 ...
-
(Elsevier Inc., 2004)Animals process and allocate energy at different seasons at variable rates, depending on their breeding season and changes in environmental conditions and resulting physiological demands. Overall total energy expenditure, ...
-
(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 ...
-
Evolutionary relationships among Massospora spp. (Entomophthorales), obligate pathogens of cicadas (Taylor & Francis, 2020)The fungal genus Massospora (Zoopagomycota: Entomophthorales) includes more than a dozen obligate, sexually transmissible pathogenic species that infect cicadas (Hemiptera) worldwide. At least two species are known to ...
-
(Finnish Zoological and Botanical Publishing Board, 2009)To date, digestive flexibility has been studied in dozens of vertebrate species. However, practically all of these works has ignored the importance of intraspecific physiological variability across populations inhabiting ...
-
(Wiley-Blackwell, 2015)The rates of oxygen consumption and carbon dioxide release of primitive hunters and weaver spiders, the Chilean Recluse spider Loxosceles laeta Nicolet (Araneae: Sicariidae) and the Chilean Tiger spider Scytodes globula ...
-
(2012)This article describes the basic prey requirements of Paraphysa sp., a small mygalomorph spider from the central Andes. Paraphysa sp. can be maintained in captivity using mealworms (Tenebrio molitor) as its primary food ...
-
(Taylor & Francis, 2017)In spiders, temperature is considered an important environmental variable for microhabitat selection. In this study, we evaluated the effect of temperature and rock size on the presence of the sand recluse spider Sicarius ...
-
(National Academy of Sciences, 2018)Bacterial endosymbionts that provide nutrients to hosts often have genomes that are extremely stable in structure and gene content. In contrast, the genome of the endosymbiont Hodgkinia cicadicola has fractured into multiple ...
-
(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 ...
-
Physiological flexibility and climate change: The case of digestive function regulation in lizards (Elsevier, 2011)Our planet is undergoing fast environmental changes,which are referred as global change. In this newscenario, it is of paramount relevance to understand the mechanistic basis of animal responses to environmental change. Here ...
-
(Springer, 2008)According to the "barrel model", an organism may be represented by a container, with input energy constraints (foraging, digestion, and absorption) symbolized by funnels connected in tandem, and energy outputs (maintenance, ...
-
(2009)A large number of physiological acclimation studies assume that flexibility in a certain trait is both adaptive and functionally important for organisms in their natural environment; however, it is not clear how an organism's ...
-
(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 ...
