Genotypes of Italian free-ranging dogs

Eugenia Natoli, Roberto Bonnani, Simona Cafazzo, Daniel Mills, Dominique Pontier & Malgorzata Pilot
Domestication has greatly changed the social and reproductive behavior of dogs relative to that of wild members of the genus Canis, which typically exhibit social monogamy and extended parental care. Unlike a typical grey wolf pack that consists of a single breeding pair and their offspring from multiple seasons, a group of free-ranging dogs (FRDs) can include multiple breeding individuals of both sexes. To understand the consequences of this shift in reproductive behavior, we reconstructed...

The effect of face masks and sunglasses on identity and expression recognition with super-recognisers and typical observers

Eilidh Noyes, Josh P. Davis, Nikolay Petrov, Katie L.H. Gray & Kay L. Ritchie
Face masks present a new challenge to face identification and emotion recognition in Western cultures. Here we present the results of three experiments that test the effect of masks, and also the effect of sunglasses (an occlusion that individuals tend to have more experience with) on 1) familiar face matching, 2) unfamiliar face matching, and 3) emotion recognition. Occlusion reduced accuracy in all three tasks, with most errors in the mask condition, however, there was...

Using a new video rating tool to crowd-source analysis of behavioural reaction to stimuli

Holly Root-Gutteridge, Jemma Forman, Louise Brown, Anna Korzeniowska, Julia Simner & David Reby
Quantifying the intensity of animals’ reaction to stimuli is notoriously difficult as classic unidimensional measures of responses such as latency or duration of looking, can fail to capture the overall strength of behavioural responses. More holistic rating can be useful but have the inherent risks of subjective bias and lack of repeatability. Here, we explored whether crowdsourcing could be used to efficiently and reliably overcome these potential flaws. A total of 396 participants watched online...

Data from: Gravity and active acceleration limit the ability of killer flies (Coenosia attenuata) to steer towards prey when attacking from above

Sergio Rossoni, Samuel Fabian, Gregory Sutton & Paloma Gonzalez-Bellido
Insects that predate aerially usually contrast prey against the sky and attack upwards. However, killer flies (Coenosia attenuata) can attack prey flying below them, performing what we term 'aerial dives'. During these dives, killer flies accelerate up to 36 m/s2. Although the trajectories of the killer fly's dives appear highly variable, proportional navigation explains them, as long as the model has the lateral acceleration limit of a real killer fly. The trajectory's steepness is explained...

Scavenging beetles control the temporal response of soil communities to carrion decomposition

Tancredi Caruso, Marco Ilardi, Sheena Cotter, Edith Hammer & Gillian Riddell
1. Carrion is a frequent but overlooked source of nutrients to the soil. The decomposition of carrion is accelerated by invertebrate scavengers but the impact of the scavengers on below-ground biota and its functions is scarcely known. 2. We conducted a laboratory experiment to investigate the effects of the burying beetle Nicrophorus vespilloides on the soil community of a temperate broadleaved forest. We assembled microcosms from soil collected from an oak woodland and treated them...

Data from: Assessing bite force estimates in extinct mammals and archosaurs using phylogenetic predictions

Manabu Sakamoto
Bite force is an ecologically important biomechanical performance measure is informative in inferring the ecology of extinct taxa. However, biomechanical modelling to estimate bite force is associated with some level of uncertainty. Here, I assess the accuracy of bite force estimates in extinct taxa using a Bayesian phylogenetic prediction model. I first fitted a phylogenetic regression model on a training set comprising extant data. The model predicts bite force from body mass and skull width...
