Objective. In the foveola of the eye, photoreceptors and Müller cells with a unique morphology have been described, but little is known about their 3D structure and orientation. Considering that there is an angle-dependent change in the foveolar photoreceptor response...

Peramelemorphia comprises four families: the extant Peramelidae (bandicoots), and Thylacomyidae (bilbies); the recently extinct Chaeropodidae (pig-footed bandicoot); and the extinct Yaralidae; with at least ten fossil species of uncertain familial affinity designated...

The Callovian Oxford Clay of England has yielded a rich and diverse marine fauna, mainly discovered and described by Alfred Leeds. However, occasionally it also brought forth terrestrial fossils, including four isolated cases of sauropod remains, one of a stegosaurid,...

The availability of free-standing water sources is a key determinant of animal and plant community structure in arid environments, and an understanding of the extent to which particular species depend on drinking water is vital for modelling the effects of climate...

A complete understanding of the feeding structures is fundamental in order to study how animals survive. Some birds use long and protrusible tongues as the main tool to collect their central caloric source (e.g. woodpeckers and nectarivores). Hummingbirds are the...

Synapsida, the clade including therapsids and thus also mammals, is one of the two major branches of amniotes. Organismal design, with modularity as a concept, offers insights into the evolution of therapsids, a group that experienced profound anatomical transformations...

The patella is a sesamoid bone located in the major extensor tendon of the knee joint, in the hindlimb of many tetrapods. Although numerous aspects of knee morphology are ancient and conserved among most tetrapods, the evolutionary occurrence of the patella is...

Structure informs function, and this may be the evolutionary reason why alternative splicing, which is capable of generating different variants of the same protein, arise. But, given the energetic cost of generating different splice variants for testing their capability...

Whilst most anthropometrical research within sport has focussed on muscle and fat distribution, more studies are measuring the relationship between stature and wingspan, which has been found to be selective criteria in many sports. In this study the stature, wingspan...

We comment on the recent developments and problems of three-dimensional printing in cardiology. Since there are currently no standards or consensuses for 3D printing in clinical medicine and the technology is at its infancy in cardiology, it’s very important to...

Walking velocity is an important control variable in gait disorders due to sensory or cerebellar disfunction. Non-preferred walking speeds are closely linked to a higher risk of falls. A compensation strategy of patients to avoid these speed sectors can be assumed....

Here we present a single working model that attempts at reconciliation of biological systems. To do this we recognize and emphasize a universal theme of all biological systems: a need for resources. That is, we consider the dynamics of resource allocation as a...
