(Ecological Society of America, 2017)The niche variation hypothesis (NVH) predicts that populations with broader niches should exhibit greater between- individual diet variation or individual specialization (IS) relative to populations with narrower niches. ...
-
(Annual Reviews, 2017)The plant endomembrane system is an extensively connected functional unit for exchanging material between compartments. Secretory and endocytic pathways allow dynamic trafficking of proteins, lipids, and other ...
-
(2013)Forestry plantations are expected to be managed in ways to conserve biodiversity while producing goods and services. This goal implies a signifi cant challenge as plantations tend to reduce species richness. The presence ...
-
(Elsevier, 2012)Nitric oxide (NO), at physiological concentrations, is a tonic inhibitory modulator of carotid body (CB) chemosensory discharges. NO modulates the chemoreception process by several mechanisms, indirectly by modifying the ...
-
(2013)Background: Among the predictions of the effect of future climate change, the impact of thermal conditions at local levels on the physiological performance of individuals and their acclimation capacities is key to ...
-
(1971)This paper discusses, first, the selective pressures which led to the two basic types of animal eyes, compound vs. camera eyes. Secondly, it considers what is the significance of the apparent similarity of the wiring ...
-
(1983)It is shown that the combined effect of resistivity, viscosity, and thermal conductivity leads to large-scale stationary convection. This is done for a cylindrical current-carrying plasma in a shearless magnetic field. ...
-
(Elsevier, 2018)The equilibrium between protein synthesis and degradation is key to maintaining efficiency in different physiological processes. The proteinase inhibitor cystatin regulates protease activities in different developmental ...
-
(Springer, 2018-09)A systems science examination of the Earth's fully interconnected dynamic magnetosphere is presented. Here the magnetospheric system (a.k.a. the magnetosphere-ionosphere-thermosphere system) is considered to be comprised ...
-
(Springer, 2018)We have analyzed the role of auroral processes in the formation of the outer radiation belt, considering that the main part of the auroral oval maps to the outer part of the ring current, instead of the plasma sheet as is ...
-
(Oxford University Press, 2018-05)Phytoplankton biomass during the austral summer is influenced by freezing and melting cycles as well as oceanographic processes that enable nutrient redistribution in the West Antarctic Peninsula (WAP). Microbial functional ...
-
(National Academy of Sciences, 2018)Abnormal modifications to mutant superoxide dismutase 1 (SOD1) are linked to familial amyotrophic lateral sclerosis (fALS). Misfolding of wild-type SOD1 (SOD1(WT)) is also observed in postmortem tissue of a subset of ...
-
(1992)To understand the taxonomic and phylogenetic relationships of Alsodes montanus and A. pehuenche the species were compared with species of the genera Alsodes and Telmatobius. Comparisons were based on internal and external, ...
-
(Elsevier, 2014)Twenty eight out of 44 Chilean freshwater fishes have been considered to fall within the vulnerable or threatened category. Thus, information about the biology, ecology and the effects of the anthropic activity on these ...
-
(Cambridge University Press, 2001)We investigated the photocurrents from isolated rods of the South American anuran, Caudiverbera caudiverbera. Rod outer segments were on average 66.4 +/ - 11.2 mum (mean +/ - S.D, n = 104) in length and 6.6 +/ - 0.9 ...
-
(American Chemical Society, 2001)The gold(I) compounds [Se(AuPPh3)2] and [Se{Au2(μ-dppf)}] (dppf = 1,1′-bis(diphenylphosphino)ferrocene) react with 1 and 2 equiv of [Au(C6F5)3OEt2] to give the mixed gold(I)-gold(III) derivatives [Se(AuPPh3)2{Au(C6 F5)3}n] ...
-
(Taylor & Francis, 2001)The distribution of Chilean temperate forests has been greatly disrupted by human activities, mainly through logging, land clearing for agriculture, and replacement of native ...
-
(Marcel Dekker, 2001)The effect of the molecular weight and concentration of the compatibilizer maleic acid-alt-styrene copolymer (MAaS) on the compatibility behavior of incompatible poly(ethylene oxide)/poly(styrene) (PEO/PS) blends was studied ...
-
(Academic Press, 2001)Fast kinetic methods are used to measure reactions that take place in less time than required to mix the reagents manually and to measure the reaction by usual methods, like UV-visible spectrophotometry and fluorescence. ...
-
(Springer, 2001)Resistance and tolerance are considered to be different plant strategies against disease. While resistance traits prevent hosts becoming parasitized or reduce the extent of parasitism, tolerance traits reduce the fitness-impact ...
