Informing elephant management through demographic snapshots
Conservation Science and Practice, EarlyView.Understanding demography is vital for managing species successfully; however, for elephants, traditional surveys are both costly and labor‐intensive. This study presents a cost‐effective method for estimating age structures of savannah elephants in southern Africa, revealing how water provisioning, density dependence, and fertility control influence ...

Felons’ chattels and English living standards in the later fourteenth and fifteenth centuries
The Economic History Review, EarlyView.Abstract The later fourteenth and fifteenth centuries have long occupied an intriguing and contested place in discussions of England's long‐run economic development. One key issue around which debate has coalesced is the living standards of the population as a whole and of different groups within it. We contribute to this debate by bringing forward new

Immunology, EarlyView.Bovine Alphaherpesvirus 1 (BoHV‐1) and Bovine respiratory syncytial virus (BRSV) are major drivers of respiratory disease in cattle. (A) To target both pathogens, two chimeric antigens—membrane‐linked and secreted—combining BoHV‐1 glycoprotein D and BRSV fusion glycoprotein were designed and expressed using recombinant BoHV‐4‐based vectors.

Calving and weaning performance of calves from heifers bred to easy calving sires
, 1994 In a calving ease comparison involving 106 calves born to first calf heifers, calves sired by Red Angus bulls were heavier at birth and required more calving assistance than Corriente-sired calves.

Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Recent studies suggest that variations in milk yield during lactation can serve as a metric for assessing individual resilience, with minimum fluctuations reflecting greater resilience in cows. With automatic milking systems, multiple records can be obtained from many cows on a daily basis. Given that animals are continually exposed to a range
