Elephant space use and habitat selection change across drought timescales

Journal of Animal Ecology, EarlyView.
Drought threatens wildlife worldwide, but little is known about wildlife behaviour during drought. This study combines 19 years of elephant GPS data with drought conditions at three timescales. Key findings include that elephants (i) move less during drought at a 1‐month timescale and (ii) change habitat selection across drought timescales.

Unknown parent groups and truncated pedigree in single-step genomic evaluations of Murrah buffaloes

Journal of Dairy Science
: Missing pedigrees may produce bias in genomic evaluations. Thus, strategies to deal with this problem have been proposed as using unknown parent groups (UPG) or truncated pedigrees.

Effect of Body Condition Score at Calving on Adaptive Immune Function During Early Lactation in New Zealand Dairy Cows: Effect of calving body condition on adaptive immune function

, 2014
The extent of postpartum negative energy balance in dairy cows is positively associated with body condition score (BCS) at calving. Results of epidemiological studies have indicated that calving BCS is positively correlated with several indicators of ...

Modeling Skin Mark Temporal Variations to Estimate the Sex of Delphinids with Low Sexual Dimorphism: Implications for Management and Conservation

Integrative Zoology, EarlyView.
This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

Genetic parameters for milk yield, age at first calving and interval between first and second calving in milk Murrah buffaloes

, 2010
In the present study, data of 1,578 first lactation females, calving from 1985 to 2006 were analysed with the purpose of estimating genetic parameters for milk yield (MY), age at first calving (AFC) and interval between first and second calving (IBFSC ...

Genetic parameters for calving rate and age at first calving in Hereford heifers [PDF]

Master of ScienceDepartment of Animal Sciences and IndustryDaniel W. MoserThe purpose of this study was to estimate the heritability of calving rate and age at first calving in Hereford heifers, and evaluate whether age at calving would add accuracy to a

The Size, Demography, and Distribution of Cambodia's Largest Elephant Population Revealed Using Traditional Genetic Tools and a Novel SNP Panel

Integrative Zoology, EarlyView.
Asian elephant population parameters were assessed using microsatellite, SNP, and sex determination DNA markers. This represents one of the first studies in mainland Asia to demonstrate that integrating microsatellite and SNP data enhances genotyping success from degraded fecal samples, increases the number of useable samples and markers, and ...

Potential vs. Realized Large Carnivore Density: The Influence of Livestock on Carnivore Carrying Capacity Estimation

Animal Conservation, EarlyView.
In an unfenced mixed‐use savanna landscape in Namibia, we compared realized densities of leopards and cheetahs estimated using spatial capture–recapture models with prey‐based carrying capacity predictions. Leopard densities exceeded predictions based on wild prey alone but closely matched livestock‐supplemented models, suggesting that vulnerable ...
