Identifying relationships between multi‐scale social–ecological factors to explore ungulate health in a Western Kazakhstan rangeland

People and Nature, 2022
Rangelands are multi‐use landscapes which are socially and ecologically important in different ways. Among other interactions, shared use of rangelands by wildlife and livestock can lead to disease transmission.

Exact spin dynamics of the 1/r^2 supersymmetric t-J model in a magnetic field

, 2006
The dynamical spin structure factor S^{zz}(Q,omega) in the small momentum region is derived analytically for the one-dimensional supersymmetric t-J model with 1/r^2 interaction. Strong spin-charge separation is found in the spin dynamics.

Within-group spatial position in Saiga tatarica (Bovidae) in the Stepnoi State Nature Sanctuary, Astrakhan Region, Russia

Nature Conservation Research: Заповедная наука, 2023
In group-living animals, the social structure and organisation play a significant role in survival and reproduction. Understanding the social aspects of animal lives in the wild may be crucially important for effective conservation of threatened species.

Partially Solvable Anisotropic t-J Model with Long-Range Interactions

, 1996
A new anisotropic t-J model in one dimension is proposed which has long-range hopping and exchange. This t-J model is only partially solvable in contrast to known integrable models with long-range interaction.

Informing aerial total counts with demographic models: population growth of Serengeti elephants not explained purely by demography [PDF]

, 2017
Conservation management is strongly shaped by the interpretation of population trends. In the Serengeti ecosystem, Tanzania, aerial total counts indicate a striking increase in elephant abundance compared to all previous censuses.

Rapidly assessing the risks of infectious diseases to wildlife species [PDF]

Royal Society Open Science, 2019
Predicting the likelihood of rare events is increasingly demanded by risk managers. A key challenge is dealing with different types of uncertainty, including epistemic uncertainties (lack of knowledge), stochasticity (inherent randomness) and natural ...

Drivers of human attitudes towards wolves Canis lupus in Kazakhstan

People and Nature, EarlyView.
Abstract Kazakhstan is recognized as a key stronghold for the grey wolf (Canis lupus). Nonetheless, the wolf status and the dynamics of human‐wolf coexistence in the region remain poorly understood. This study aims to fill that gap by exploring current attitudes towards wolves in Kazakhstan and identify the underlying drivers of these attitudes.

Dynamical Properties of the 1/r^2-Type Supersymmetric t-J Model in a Magnetic Field: Manifestation of Spin-Charge Separation

, 2000
Quasi-particle picture in a magnetic field is pursued for dynamical spin and charge correlation functions of the one-dimensional supersymmetric t-J model with inverse-square interaction.

A study into the current state of Saiga tatarica L. populations with the use of retrospective data

Acta Scientiarum: Animal Sciences
The saiga antelope (Saiga tatarica tatarica L., 1766, S) is a prominent ungulate mammal species inhabiting Central Asia. Over the latter half of the 20th century, saiga populations, including the Volga-Ural (Kazakhstan) population, experienced a ...

125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

Journal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...
