Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

A nesting area suitability model (MISN) to estimate the population parameters of Rock Partridge, Alectoris graeca orlandoi, in Rieti and Frosinone Provinces

Rivista Italiana di Ornitologia - Research in Ornithology, 2012
In the last decades the Rock Partridge has undergone a decline throughout the entire area of distribution. The abundance of Apennine Rock Partridge, Alectoris graeca orlandoi, in the provinces of Frosinone and Rieti has been estimated with the pre ...

Exploring the nature and focus of feedback when using video playback in gynecology laparoscopy training

Canadian Medical Education Journal, 2021
Background: Feedback about intraoperative performance remains a cornerstone of surgical training. Video playback offers one potential method for more effective feedback to surgical residents. More research is needed to better understand this method. This

Timing of antisynchronous calling: A case study in a harbor seal pup (Phoca vitulina)

, 2019
Alternative mathematical models predict differences in how animals adjust the timing of their calls. Differences can be measured as the effect of the timing of a conspecific call on the rate and period of calling of a focal animal, and the lag between ...

QoE Optimization of Video Multicast with Heterogeneous Channels and Playback Requirements [PDF]

, 2015
We propose an application-layer forward error correction (AL-FEC) code rate allocation scheme to maximize the quality of experience (QoE) of a video multicast. The allocation dynamically assigns multicast clients to the quality layers of a scalable video

The As and Bs of titi monkey linguistics: why emotional communication is not the enemy

Biological Reviews, EarlyView.
ABSTRACT The alarm call sequences of titi monkeys (genera Plecturocebus, Callicebus and Cheracebus) have sparked important debates over whether they exhibit parallels with human language. Some researchers consider these sequences to involve both semantics and syntax, while others argue that the sequences convey semantic information without syntax.

Estimating density of a rare and cryptic high-mountain Galliform species, the Buff-throated Partridge Tetraophasis szechenyii

Avian Conservation and Ecology, 2016
Estimates of abundance or density are essential for wildlife management and conservation. There are few effective density estimates for the Buff-throated Partridge Tetraophasis szechenyii, a rare and elusive high-mountain Galliform species endemic to ...

Consumer diversity drives stronger predation in tropical marine communities

Ecography, EarlyView.
Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Regular Exposure to Cowbells Affects the Behavioral Reactivity to a Noise Stimulus in Dairy Cows

Frontiers in Veterinary Science, 2017
In alpine regions, cows are often equipped with bells during pasture season to ensure that farmers can locate them. Constant exposure to the chime of a bell may affect cows’ acoustic perception in general. The aim of this study is to test whether routine
