Among seabirds, alcids are particularly sensitive to bycatch in fisheries and oil pollution, yet their distribution at sea remains scarcely known in most of their breeding areas. GPS telemetry data of fifteen individuals of alcids (5 Razorbills 6 Common Murres and 4 Puffins) were analyzed to determine their distribution during the breeding period of 2016 at Saint Pierre and Miquelon Archipelago (SPM). Two analytical methods (threshold and a switching state-space model) were used to identify behavioral modes and foraging areas. We compared foraging movements and estimated the overlap between the species. Distribution and foraging covered an area located between SPM and Newfoundland. Our results revealed that the three species headed northward of their...

Studying nomadic animal movement across species and ecosystems is essential for better understanding variability in nomadism. In arid environments, unpredictable changes in water and forage resources are known drivers of nomadic movements. Water resources vary temporally but are often spatially stationary, whereas foraging resources are often both temporally and spatially variable. These differences may lead to different types of nomadic movements: forage‐ vs. water‐driven nomadism. Our study investigates these two different types of nomadism in relation to resource gradients from mesic steppe to xeric desert environments in Mongolia's Gobi‐Steppe Ecosystem. We hypothesized that in the desert, where water is a key resource, animals are more water‐dependent...

EQUINE '98, PART II: BASELINE REFERENCE OF 1998 EQUINE HEALTH AND MANAGEMENT
Provedor de dados: 31
Autores: Garber,   Lindsey.
The NAHMS Equine '98 Study was designed to provide both participants and the industry with information on the nation's equine population for education and research.  The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample such that inferences can be made for all places with equids and for all equids in the participating states.  Included in the study were 28 states that accounted for 78.2 percent of the U.S. horses and ponies and 78.0 percent of farms with horses and ponies.  NASS  interviewers collected data from 2,904 participants via questionnaire from March 16 through April 10, 1998 for Part II.        Contact for this paper: Lindsey Garber
