A GIS‐Based Approach to Modeling Carnivore Activity in the Pleistocene Site of Cova del Rinoceront (Iberian Peninsula)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.

Production and economic traits of purebreed and crossbred animals in diary herds of mountain areas [PDF]

open access: yes, 2013
Beef production from dairy herds represents an alternative source to improve the farm profitability. The use of beef semen to mate cattle not destined to breed replacement represent an interesting source of income for dairy farmers particularly due to ...

Fruit use and fruit processing by euphonias, specialized avian frugivores

open access: yesOikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

RELATIONSHIP BETWEEN ATTRIBUTES OF BEEF CATTLE RAISED USING ULTRASOUND TECHNOLOGY AND PRICES RECEIVED AT THE PACKERS: A HEDONIC PRICE ANALYSIS

open access: yes
Sluggish growth in per capita consumption and a downward pressure on beef price at the farm level has required producers to raise cattle that precisely target the meat attributes desired by consumers.

Large, rugged and remote: The challenge of wolf–livestock coexistence on federal lands in the American West

open access: yesPeople and Nature, EarlyView.
Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.

Unveiling human–wildlife interactions in the context of livestock grazing abandonment and the return of large carnivores, ungulates and vultures: A stakeholder perspective

open access: yesPeople and Nature, EarlyView.
Abstract Pastoral practices remain a widespread economic activity across European mountain regions. However, the viability of this activity may be threatened by the recovery of large wild vertebrates associated with passive rewilding, leading to the so‐called human–wildlife conflicts.

Drivers of human attitudes towards wolves Canis lupus in Kazakhstan

open access: yesPeople 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.

Grid Marketing and Beef Carcass Quality: A Discussion of Issues and Trends [PDF]

open access: yes
Beef industry data suggest that improvements in carcass yield and quality grades have stagnated recently. Empirical analysis, based on USDA market reports, indicates that the share of steer slaughter volume marketed on a grid is less than industry ...

Understanding contingency in wolf‐mediated livestock predation across a mosaic of land uses: An agent‐based modelling approach

open access: yesPeople and Nature, EarlyView.
Abstract The return of grey wolves to multi‐use landscapes in North America and Europe raises concerns over accompanying risks of livestock predation. While local‐level risk factors have received attention, it is difficult to explore the role that landscape‐scale variables, such as landscape connectivity, play in driving livestock losses.
