Parental investment in child health in sub-Saharan Africa: a cross-national study of health-seeking behaviour
(2016)Parents face trade-offs between investing in child health and other fitness enhancing activities. In humans, parental investment theory has mostly been examined through the analysis of differential child outcomes, with ... -
X-ray microtomography provides first data about the feeding behaviour of an endangered lizard, the Montserrat galliwasp
(2015)Reporting the diet of recently extinct or very rare taxa, only known by a few museum specimens, is challenging. This study uses X-ray microtomography, a non-destructive investigation method, to obtain the first data about ... -
Simultaneous DNA-based diet analysis of breeding, non-breeding and chick Adélie penguins
(2016)As central place foragers, breeding penguins are restricted in foraging range by the need to return to the colony to feed chicks. Furthermore, breeding birds must balance energetic gain from self-feeding with the costs of ... -
First evidence of hybridization between golden jackal (Canis aureus) and domestic dog (Canis familiaris) as revealed by genetic markers
(2015)Interspecific hybridization is relatively frequent in nature and numerous cases of hybridization between wild canids and domestic dogs have been recorded. However, hybrids between golden jackals (Canis aureus) and other ... -
Modelling mass and heat transfer in nano-based cancer hyperthermia
(2015)Department of Mechanical Engineering andMaterials Science, University of Pittsburgh, Pittsburgh, PA, USA 2 Department of Translational Imaging, HoustonMethodist Research Institute, Houston, TX, USA 3 Modeling and Scientific ... -
Comparing and modelling land use organization in cities
(2015)The advent of geolocated information and communication technologies opens the possibility of exploring how people use space in cities, bringing an important new tool for urban scientists and planners, especially for regions ... -
Biophysical basis for convergent evolution of two veil-formingmicrobes
(2015)Microbes living in stagnant water typically rely on chemical diffusion to draw nutrients from their environment. The sulfur-oxidizing bacterium Thiovulum majusand the ciliate Uronemellahave independently evolved the ability ... -
The role of social and ecological processes in structuring animal populations
(2015)Both social and ecological factors influence population process and structure, with resultant consequences for phenotypic selection on individuals. Understanding the scale and relative contribution of these two factors is ... -
Morphological and functional changes in the vertebral columnwith increasing aquatic adaptation in crocodylomorphs
(2015)The lineage leading to modern Crocodylia has undergone dramatic evolutionary changes in morphology, ecology and locomotion over the past 200+Myr. These functional innovations may be explained in part by morphological changes ... -
Simulated annealing approach to vascular structure with application to the coronary arteries
(2016)Department of Physical Sciences, The Open University, Milton Keynes MK7 6AA, UK 2 Department of Cardiovascular Sciences, University of Leicester, Leicester LE1 5WW, UK Do the complex processes of angiogenesis during organism ... -
Distributed acoustic cues for caller identity inmacaque vocalization
(2015)Individual primates can be identified by the sound of their voice. Macaques have demonstrated an ability to discern conspecific identity from a harmonically structured ‘coo’ call. Voice recognition presumably requires the ... -
Clover root exudate produces male-biased sex ratios and accelerates male metamorphic timing in wood frogs
(2015)In amphibians, abnormal metamorph sex ratios and sexual development have almost exclusively been considered in response to synthetic compounds like pesticides or pharmaceuticals. However, endocrine-active plant chemicals ... -
Variation in thermal stress response in two populations of the brown seaweed, Fucus distichus from the Arctic and subarctic intertidal
(2016)It is unclear whether intertidal organisms are ‘preadapted’ to cope with the increase of temperature and temperature variability or if they are currently at their thermal tolerance limits. To address the dichotomy, we ... -
Analysis of iris surface features in populations of diverse ancestry
(2016)There are many textural elements that can be found in the human eye, including Fuchs’ crypts, Wolfflin nodules, pigment spots, contraction furrows and conjunctival melanosis. Although iris surface features have been ... -
Transformation of the genital epithelial tract occurs early in California sea lion development
(2016)An unusually high prevalence of metastatic urogenital carcinoma has been observed in free-ranging California sea lions stranded off the coast of California in the past two decades. No cases have been reported for sea lions ... -
Regulatory mechanisms of group distributions in a gregarious arthropod
(2015)In a patchy environment, how social animals manage conspecific and environmental cues in their choice of habitat is a leading issue for understanding their spatial distribution and their exploitation of resources. Here, ... -
Decision level adaptation inmotion perception
(2015)Prolonged exposure to visual stimuli causes a bias in observers’ responses to subsequent stimuli. Such adaptation-induced biases are usually explained in terms of changes in the relative activity of sensory neurons in the ... -
Control Strategies for Variable-speed Fixed-pitch Wind Turbines
(INTECH Open Access Publisher, 2010)This chapter is emphasized on control strategies for a variable speed fixed-pitch wind turbine with the main objective to optimize energy capture in below- and above-rated wind speed regions. Two main laboratory experiments ... -
Biologically Motivated Vergence Control System Based on Stereo Saliency Map Model
(INTECH Open Access Publisher, 2007)We proposed a new biologically motivated vergence control method of an active stereo vision system that mimics human-like stereo visual selective attention. We used a trainable selective attention model that can decide an ... -
Nutritional Deficiency. Chapter 7: Malaria, Schistosomiasis, and Related Anemia
(INTECH Open Access Publisher, 2016)Parasitic infections (e.g., malaria and helminthiases) have a huge impact on public health in endemic areas. Moreover, parasitic infestations are prominent causes of anemia in the tropics and subtropics, further perpetuated ...
