(2012)Cephalopods have two main defence strategies: the first consists on reducing the odds of being detected by a predator, while the second focuses on avoiding capture. The aim of this study was to understand the basic behavioural ...
-
(Springer, 2013)The invasion or expansion of non-native species into new geographic areas can pose a major threat to the conservation of biodiversity. These threats are augmented when the newly-arrived species interacts with native ...
-
(2002)The Palaeoarctic parasitoid Aphidius ervi Haliday (Hymenoptera, Aphidiidae) parasitises legume aphids in its region of origin. In Chile, it parasitises both legume and cereal aphids. This special situation was studied at ...
-
(2005)Host plant selection and acceptance by aphids involves four consecutive steps: (1) prealighting behaviour, (2) leaf surface exploration and probing of subepidermal tissues, (3) deep probing of plant tissues, and (4) ...
-
(2001)The effects of parasitisation by Aphidius ervi on the thermoregulatory behaviour of the pea aphid Acyrtosiphon pisum were studied in alfalfa fields and in an experimental thermal gradient. In the field, mummies were found ...
-
(2016)We present benchmark values for the electronic chemical potential and chemical hardness from reference data for ionization potentials and electron affinities. In cases where the energies needed to compute these quantities ...
-
(Nature, 2020)The explosion of network science has permitted an understanding of how the structure of social networks affects the dynamics of social contagion. In community-based interventions with spill-over effects, identifying ...
-
(Royal Soc Chemistry, 2018)The bending process of 2D materials, subject to an external force, is investigated, and applied to graphene, molybdenum disulphide (MoS2), and imogolite. For graphene we obtained 3.43 eV angstrom(2) per atom for the bending ...
-
(2010)1. A key aspect of the ecology and evolution of adaptive prey responses to predator risk is the timing by which the former develop a defensive trait in response to inducing signals released by the latter. This property, ...
-
(Springer, 2019)We define and study coherent states, a Berezin-Toeplitz quantization and covariant symbols on the product Xi := G x g(#) between a connected simply connected nilpotent Lie group and the dual of its Lie algebra. The starting ...
-
beta 1-subunit-induced structural rearrangements of the Ca2+- and voltage-activated K+ (BK) channel (Natl Acad Sciences, 2016)Large-conductance Ca2+- and voltage-activated K+ (BK) channels are involved in a large variety of physiological processes. Regulatory beta-subunits are one of the mechanisms responsible for creating BK channel diversity ...
-
(COMPANY OF BIOLOGISTS LTD, 2006-10-30)A number of psychiatric and neurodegenerative disorders, such as Alzheimer’s disease, are characterized by abnormalities in the neuronal cytoskeleton. Here, we find that the enhancement in actin polymerization induced ...
-
(2007)A theoretical study of the beta-scission reactions for some thioimidoyl radicals (R-1-N=C-center dot-S-R-2) using a recently introduced homofugality index, nu(center dot) is presented. This index, that was defined as a ...
-
(ELSEVIER GMBH, 2010-08-28)The flexibility of digestive traits characterizes a standard model of physiological flexibility, demonstrating that animals adjust their digestive attributes in order to maximize overall energy return. Using an intraspecific ...
-
(Ecological Society of Australia, 2007)In this work we report on the seasonal trends of abundances in terms of temperature exposure for four coexisting cladoceran species (Daphnia ambigua (Daphniidae), Ceriodaphnia dubia (Daphniidae), Diaphanosoma chilense ...
-
(Sociedad de Biologia de Chile, 2009)In this essay I point out to two processes that can potentially complement the classical view of evolution by natural selection as outlined by Darwin, which captures only part of the processes driving adaptive evolution. ...
-
(2016)Habitat structure determines species occurrence and behavior. However, human activities are altering natural habitat structure, potentially hampering native species due to the loss of nesting cavities, shelter or movement ...
-
(WILEY-V C H VERLAG GMBH, 2007-03)The definition of life has excited little interest among molecular biologists during the past half-century, and the enormous development in biology during that time has been largely based on an analytical approach in ...
-
(John Wiley, 2015)1. The effects of the present biodiversity crisis have been largely focused on the loss of species. However, a missed component of biodiversity loss that often accompanies or even precedes species disappearance is the ...
-
(Plos One, 2013)CNBP is a nucleic acid chaperone implicated in vertebrate craniofacial development, as well as in myotonic dystrophy type 2 (DM2) and sporadic inclusion body myositis (sIBM) human muscle diseases. CNBP is highly conserved ...
