Hypercanines: Not just for sabertooths

The Anatomical Record, EarlyView.
Abstract Hypercanines are here defined as hypertrophied caniniform teeth, that is, canine teeth that are elongated to serve specific functions in different clades of mammals and their synapsid ancestors. This article presents an overview of the occurrence of hypercanines, their growth, and their function across a broad range of clades.

The anti-predatory behavioral repertoire of Drosophila melanogaster [PDF]

, 2013
This is the poster presented by the first author, Abhijna Anand Parigi, at the 4th annual BEACON congress, August 2013 at Michigan State University. This represents some of our currently unpublished work to describe the set of behaviors (ethogram) for Drosophila melanogaster under risk of predation by the Zebra jumping spider (Salticus scenicus).

Multiple Anti-Predatory Behaviors in Red-Tailed Monkey (Cercopithecus ascanius) Groups Reveal Distinct Landscapes of Fear [PDF]

, 2020
Foraging opportunity and predation risk can act as opposing influences on an animal’s habitat use. This opposition can be addressed with a “landscape of fear” (LOF), where models predict the spatial distribution of predators or perceived predator ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Small fish, large variation: Morphological diversity of Weberian apparatus in Noturus catfishes and ecological implications

The Anatomical Record, EarlyView.
Abstract The Weberian apparatus is a hearing specialization unique to the otophysan fishes, and an unexpected degree of morphological variation exists in species of the Noturus catfishes. Our aim in this study is to investigate relationships between morphological variations and ecology that may drive this variation.

Comparative analysis of optional hunting behavior in Cricetinae hamsters using the data compression approach

Frontiers in Zoology
Research into the hunting behavior in members of the Cricetidae family offers an opportunity to reveal what changes in the predatory behavioral sequences occur when a rodent species shifts from an omnivorous to a predatory lifestyle.

Variability of jaw muscles in Tunisian street dogs and adaptation to skull shape

The Anatomical Record, EarlyView.
Abstract The impact of artificial selection on the masticatory apparatus of dogs has been poorly studied, and comparative data with dogs subjected to more natural constraints are lacking. This study explores the jaw musculature of Tunisian street dogs, which are largely free from the influence of breed‐specific selection.

New record of predatory ladybird beetle (Coleoptera, Coccinellidae) feeding on extrafloral nectaries

Revista Brasileira de Entomologia, 2011
New record of predatory ladybird beetle (Coleoptera, Coccinellidae) feeding on extrafloral nectaries. Feeding by Exoplectra miniata (Germar) on extrafloral nectaries of Inga edulis Mart. was observed in Nova Friburgo, Rio de Janeiro, Brazil.

Prey density affects predator foraging strategy in an Antarctic ecosystem

Ecology and Evolution, 2020
Studying the effects of prey distribution on predator behavior is complex in systems where there are multiple prey species. The role of prey density in predator behavior is rarely studied in closed ecosystems of one predator species and one prey species,

Prey-tracking behavior and prey preferences in a tree-climbing firefly [PDF]

PeerJ, 2019
Prey-tracking behavior is common in snail-killing predators, but in the family Lampyridae, this behavior has been validated in only a single species even though this Coleopteran family includes many specialist snail predators.
