Heart Rate as an Indicator of Stress in Gotland's Russ Horses

open access: yesZoo Biology, EarlyView.
ABSTRACT Animal welfare concerns both the physical and mental wellbeing of animals so the assessment of animals kept in captivity, for example zoos, is important and necessary both legally and ethically. Good welfare is especially vital when breeding endangered species as stress impairs reproductive investment.

Individual Welfare Gains from Deferred Life-Annuities under Stochastic Lee-Carter Mortality [PDF]

open access: yes
A deferred annuity typically includes an option-like right for the policyholder. At the end of the deferment period, he may either choose to receive annuity payouts, calculated based on a mortality table agreed to at contract inception, or receive the ...

Spatiotemporal dynamics and machine learning‐based prediction of above‐ground biomass in the Indus Delta mangroves

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mangrove forests are important blue carbon ecosystems, yet long‐term above‐ground biomass (AGB) dynamics in arid deltaic systems remain poorly understood. Here, we integrated field‐derived AGB data with multisource remote sensing and machine learning models (random ...

Social network dynamics under experimental manipulations of predation risk and food abundance in wild rock hyraxes

open access: yesJournal of Animal Ecology, EarlyView.
This study combines replicated experimental manipulation, social network analysis, network permutations and meta‐analysis to disentangle active from spatially‐induced changes in animal network structure in the wild. It reveals that short‐term environmental changes primarily alter space use, with limited effects on social structure.

Life is Cheap: Using Mortality Bonds to Hedge Aggregate Mortality Risk [PDF]

open access: yes
Using the widely-cited Lee-Carter mortality model, we quantify aggregate mortality risk as the risk that the average annuitant lives longer than is predicted by the model, and we conclude that annuity business exposes insurance companies to substantial ...

Towards an anthropology of acquisition: ‘How did you get that?’ Vers une anthropologie de l'acquisition : « Où as‐tu trouvé ça ? »

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The production‐distribution‐consumption triad has structured how anthropologists understand exchange for roughly a century. This article argues for expanding this triad to include an explicit focus on acquisition – the systems, processes, and practices of acquiring.

‘Fine Men from Afar’: Cricket and Empire on the Home Front

open access: yesHistory, EarlyView.
Abstract During the Second World War, contrary to enduring images of bombardment and scarcity, people on Britain's ‘Home Front’ continued to take part in a broad array of sporting activities. Cricket played a more significant role in the wartime sporting landscape than many historians have previously recognized.

In the core of longevity risk: hidden dependence in stochastic mortality models and cut-offs in prices of longevity swaps [PDF]

open access: yes
In most stochastic mortality models, either one stochastic intensity process (for example a jump-diffusion process) or a collection of independent processes is used to model the stochastic evolution of survival probabilities.
