(Wiley, 2015)Flying Dinosaurs is a timely popular work, focusing especially on the latest research related to the dinosaur-bird link. This short and enjoyable book provides an updated summary of discoveries such as dinosaurs preserved ...
-
(2011)Phosphofructokinase-2 is a 66 kD homodimer whose subunits are associated by means of a bimolecular domain, the β-clasp, which is linked to the larger portion of each subunit by a reentrant chain topology. To investigate ...

(Blackwell Publishing Ltd, 2017)© 2016 John Wiley & Sons Ltd Aim: We use an integrative biogeographical approach to further understand the evolution of an important Southern Ocean marine benthic element, the limpet genus Nacella (Mollusca: Patellogastropoda). ...
-
(1992)Polyglutamate analogs of folate and related compounds were tested as inhibitors of casein kinase II (CK II) obtained from Xenopus laevis. The inhibitory capacity of the pteroyl, 4-amino-10-methyl pteroyl (the methotrexate ...
-
(Ecological Society of America, 1997)The degu, Octodon degus (Rodentia, Octodontidae) is a diurnal herbivore inhabiting the semiarid and mediterranean environments of northern and central Chile. In the field, degus are constrained to specific foraging areas, ...
-
(2013)We assessed foraging activity of insectivorous bats in a fragmented landscape of central Chile including native temperate forest, forest fragments, commercial pine plantations and local human settlements. Overall bat ...
-
(Public Library Science, 2016)Theoretical models predict that animals should make foraging decisions after assessing the quality of available habitat, but most models fail to consider the spatio-temporal scales at which animals perceive habitat ...
-
(2003)We investigated the effects of forest patch size on the behaviour of birds feeding on the fower nectar of the proteaceous tree Embothrium coccineum J. R. et G. Forster, which is typically restricted to forest edges in ...
-
(Nature, 2020)Fatty acids have been widely used as trophic biomarkers in marine mammals. However, for the South American sea lion, the most abundant otariid in the eastern South Pacific, there is no information about blubber fatty acids ...
-
(2008)This paper analyzes recursive and rolling neural network models to forecast one-step-ahead sign variations in gold price. Different combinations of techniques and sample sizes are studied for feed forward and ward neural ...

(AAGR Aerosol and Air Quality Research, 2018)© Taiwan Association for Aerosol Research. We present the results of a neural network model designed for the forecasting of hourly PM2.5 concentrations in Santiago, Chile. The study focuses on the observed values at two ...
-
(Asociacion Paleontologica Argentina, 2017)Many dinosaur skeletons show evidence of behavior, including feeding, predation, nesting, and parental care. The resting posture of the forelimbs has been studied in some theropod species, in relation to the acquisition ...
-
(Elsevier, 2003)Fragmentation of forest landscapes can raise the intensity of nest predation by increasing the abundance and richness of generalist or introduced predators. Understory foraging birds, such as rhinocryptids, can be highly ...
-
(Wiley, 2018-07)The diversity and distribution of the genetic variation in forest phytophagous insect populations can be highly sensitive to forest fragmentation. This should be particularly evident for monophagous insects living on ...
-
(2012)The need for conservation outside protected areas has prompted the modifi cation of productive practices to allow the maintenance of wild biota in productive landscapes such as those associated to timber production. Forest ...
