Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Individual variation and repeatability of the behavioral response to novel objects in captive African elephants (Loxodonta africana)

open access: yesDiscover Animals
Individuals differ consistently in their behavioral responses to novel situations. In zoo animals, such evidence can help to design enrichment programs to improve individual welfare, an area of increasing efforts in the zoo community.

Some observations on the temporal variations of size of copepods and some answers to questions on their biology. [Translation from: Internationale Revue der Gesamten Hydrobiologie und Hydrographie 17 99-114, 1927.] [PDF]

open access: yes, 1927
Until now observations on the temporal variation of size of freshwater copepods have not provided much information. Other observers only mention in passing this or that phenomenon from which it is possible to deduct termporal variations.

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

open access: yesEcography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

The pedagogy of encounter: how do zoo interpreters account for their facilitation of interspecies encounters between visitors and captive animals? [PDF]

open access: yes, 2015
Zoo interpreters have an important role to play in enhancing the educational potential of an informal learning setting. Nonetheless, little is known about what motivates individuals to pursue a profession in zoo interpretation, or how these individuals ...
