Geographic variation in external morphology is thought to reflect an interplay between genotype and the environment. Morphological variation has been well-described for a number of cetacean species, including the bottlenose dolphin (Tursiops truncatus). In this...

I used radio-telemetry to track the movements of Mangrove Cuckoos (Coccyzus minor) captured in southwest Florida. Relatively little is known about the natural history of Mangrove Cuckoos, and my goal was to provide an initial description of how individuals use...

Our ability to prevent extinction in declining populations often depends on effective management of habitats that are disturbed through wildfire, logging, agriculture, or development. In these disturbed landscapes, the juxtaposition of multiple habitat types can...

We recently found Cribrinopsis japonica Tsutsui & Tsuruwaka, 2014 (Shinkai-hakutou-ginchaku in Japanese name) at the depth between 384 and 800 m in Toyama Bay, Sea of Japan. Since then, C. japonica has been reared under atmospheric pressure in the laboratory for...

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...

Introduction. Planarians are renowned for their regenerative ability due to pluripotent stem cells, as well as their peculiar photophobic response. However, few facts are known about their aggregational behavior. This study aims to reveal the effect of light on...

1) DNA metabarcoding holds great promise for the assessment of macroinvertebrates in stream ecosystems. However, few large-scale studies have compared the performance of DNA metabarcoding with that of routine morphological identification. 2) We performed metabarcoding...

Camera loggers are increasingly used to examine behavioural aspects of free-ranging animals. However, often video loggers are deployed with a focus on specific behavioural traits for which it suffices to use cameras that are small but often have a limited field...

The goal of educating the public about environmental and conservation issues is found in the mission statements of almost every zoo in the world. In order to effectively teach their visitors, zoos must understand how they are communicating with their public. In...

A novel reconstruction of the nodosaurid dinosaur Struthiosaurus austriacus Bunzel 1871 is presented. Because bones and dermal armor are preserved as disarticulated elements only and because of the lack of field notes from the original excavation(s), any attempt...

Ceratopsids (“horned dinosaurs”) are known from numerous specimens in western North America and Asia, a distribution reflecting the inferred subaerial link between the two landmasses during the Late Cretaceous. However, this clade was previously unknown from eastern...

Background. The Balkans are a major biodiversity and endemism hotspot, worldwide. Among the freshwater biota, amphipods are known for their high cryptic diversity. However, little is known about the temporal and paleogeographic aspects of their evolutionary history....

1) Environmental bulk samples often contain many taxa with biomass differences of several orders of magnitude. This can be problematic in DNA metabarcoding and metagenomic high throughput sequencing approaches, as large specimens contribute disproportionate amounts...

The polar bear (Ursus maritimus) was the first species to be classified as threatened with extinction based on predictions of future conditions rather than current status. These predictions were made using expert-opinion forecasts of population declines linked...

1. Interspecific relationships, termed symbiosis, are considered very diverse, while intraspecific relationships have just two categories. 2. The present classification fails to define all interactions among members of the same species, as demonstrated by observations...
