A model of muscle atrophy based on livemicroscopy of muscle remodelling in Drosophila metamorphosis
(2016)Genes controlling muscle size and survival play important roles in muscle wasting diseases. In Drosophila melanogaster metamorphosis, larval abdominal muscles undergo two developmental fates. While a doomed population is ... -
Across-shelf distribution of bluemussel larvae in the northern Gulf of Maine
(2015)Studies of population connectivity have largely focused on along-shelf, as opposed to across-shelf, processes. We hypothesized that a discontinuity in across-shelf mixing caused by the divergence of the Eastern Maine Coastal ... -
Hodgkin–Huxley revisited
(2015)As cardiac cell models become increasingly complex, a correspondingly complex ‘genealogy’ of inherited parameter values has also emerged. The result has been the loss of a direct link between model parameters and experimental ... -
Heidelberg-mCT-Analyzer
(2015)Bone tissue engineering and bone scaffold development represent two challenging fields in orthopaedic research. Micro-computed tomography (mCT) allows non-invasive measurement of these scaffolds’ propertiesin vivo. However, ... -
Estimating cranial musculoskeletal constraints in theropod dinosaurs
(2015)Many inferences on the biology, behaviour and ecology of extinct vertebrates are based on the reconstruction of the musculature and rely considerably on its accuracy. Although the advent of digital reconstruction techniques ... -
Rapid mimicry and emotional contagion in domestic dogs
(2015)Emotional contagion is a basic form of empathy that makes individuals able to experience others’ emotions. In human and non-human primates, emotional contagion can be linked to facial mimicry, an automatic and fast response ... -
A comprehensive study of the delay vector variance method for quantification of nonlinearity in dynamical systems
(2016)Although vibration monitoring is a popular method to monitor and assess dynamic structures, quantification of linearity or nonlinearity of the dynamic responses remains a challenging problem. We investigate the delay vector ... -
Sex differences in risk-taking and associative learning in rats
(2015)In many species, males tend to have lower parental investment than females and greater variance in their reproductive success. Males might therefore be expected to adopt more high-risk, high-return behaviours than females. ... -
Only accessible information is useful
(2015)Information theory is gaining popularity as a tool to characterize performance of biological systems. However, information is commonly quantified without reference to whether or how a system could extract and use it as a ... -
Unexpected monophyletic origin of Ephoron shigae unisexual reproduction strains and their rapid expansion across Japan
(2015)The burrowing polymitarcyid mayflyEphoron shigaeis distri-buted across Japan, Korea, northeast China and far east Russia. Some populations are bisexual, and others are unisexual, i.e. geographically parthenogenetic throughout ... -
Evolutionary diversification of retinoic acid receptor ligand-binding pocket structure bymolecular tinkering
(2016)Whole genome duplications (WGDs) have been classically associated with the origin of evolutionary novelties and the so-called duplication–degeneration–complementation model describes the possible fates of genes after ... -
A highly infective plant-associated bacterium influences reproductive rates in pea aphids
(2016)Pea aphids, A cyrthosiphon pisum, have the potential to increase reproduction as a defence against pathogens, though how frequently this occurs or how infection with live pathogens influences this response is not well ... -
A new Early Oligocene toothed ‘baleen’ whale from western North America
(2015)Archaic toothed mysticetes represent the evolutionary transition from raptorial to bulk filter feeding in baleen whales. Aetiocetids, in particular, preserve an intermediate morphological stage in which teeth functioned ... -
The potential for climate-driven bathymetric range shifts
(2015)Range shifts are of great importance as a response for species facing climate change. In the light of current ocean-surface warming, many studies have focused on the capacity of marine ectotherms to shift their ranges ... -
A stochastic vision-based model inspired by zebrafish collective behaviour in heterogeneous environments
(2016)Collective motion is one of the most ubiquitous behaviours displayed by social organisms and has led to the development of numerous models. Recent advances in the understanding of sensory system and information processing ... -
Reduced entomopathogen abundance in Myrmicaant nests
(2015)Social insects such as ants have evolved collective rather than individual immune defence strategies against diseases and parasites at the level of their societies (colonies), known as social immunity. Ants frequently host ... -
First report of Plesiochelys etalloniandTropidemys langiifrom the Late Jurassic of the UK and the palaeobiogeography of plesiochelyid turtles
(2016)Plesiochelyidae is a clade of relatively large coastal marine turtles that inhabited the shallow epicontinental seas that covered western Europe during the Late Jurassic. Although the group has been reported from many ... -
Unnoticed in the tropics
(2015)Ricinulei are among the most obscure and cryptic arachnid orders, constituting a micro-diverse group with extreme endemism. The 76 extant species described to date are grouped in three genera:Ricinoides, from tropical ... -
Molecular identification of Oesophagostomumspp
(2015)Oesophagostomumspp. are parasitic nematodes of mammals, including humans and other primates. To identify species and determine phylogeny, we analysed DNA sequences of adult and larvalOesophagostomumfrom wild chimpanzees ... -
The easternmigratory caribou
(2016)Understanding the evolutionary history of contemporary animal groups is essential for conservation and management of endangered species like caribou (Rangifer tarandus). In central Canada, the ranges of two caribou subspecies ...
