Predicting Infection Risk Of Airborne Foot-And-Mouth Disease
Foot-and-mouth is a highly contagious disease of global socio-economic importance. In countries considered disease-free the control and eradication of any outbreak is reliant upon prompt detection of infected premises. Our paper presents a practical method for predicting airborne infections and prioritising farms for inspection in such a situation, with results applied a recent outbreak.

First Fossil Gravid Turtle Provides Insight Into The Evolution Of Reproductive Traits In Turtles
This study reports on the first fossil turtle with eggs preserved within the body cavity, as well as on one of the few known North American fossil turtle nests. These fossils belong to an extinct turtle called Adocus, and were found in 75 million year old rocks in Alberta, Canada. The specimens reveal that Adocus built its nests near rivers and laid large clutches of thick-shelled, hard, spherical eggs.

Evolutionary Conservation Of Mechanisms For Neuronal Regionalization, Proliferation And Interconnection In Brain Development
Comparative studies of different aspects of brain development in vertebrates and invertebrates reveal remarkable similarities in expression and function of key developmental control genes. Indeed, vertebrates and invertebrates share a complex set of control genes and molecular genetic interactions that are responsible for neural induction, regionalized patterning, progenitor proliferation, and circuit formation in the developing brain.

Social Personality Trait And Fitness
Animal personalities are defined as consistent individual differences across time and context. We recently demonstrated that social personality traits (i.e. sociability) exist in the common lizard and that the variation of sociability provides an explanation for variable habitat preferences within a given species. Here, we showed that the variation in sociability also affect individual success across habitats of different population densities.

Temperature Dependent Sex-biased Embryo Mortality In A Bird
This is the first study to show temperature dependent sex-biased embryo mortality operating in a bird. Molecular sexing of chicks and embryos of the Australian Brush-turkey (Alectura lathami) confirmed that male embryo mortality was greater at high temperatures while female mortality is greater at low temperatures, with mortality in both sexes similar at intermediate incubation temperatures.

Animals Adapt Their Vocal Signals To Social Situations
A special August issue of the Journal of Comparative Psychology, published by the American Psychological Association, presents a host of studies that investigate the way that animals adapt their calls, chirps, barks and whistles to their social situation.

Moving With The Beat: Heart Rate And Visceral Temperature Of Free-Swimming And Feeding Bluefin Tuna
Nothing is known of the cardiovascular function of free-swimming bluefin tuna. We used a surgically-implanted data logger to measure heart rate and visceral temperature of free-swimming and feeding southern bluefin tuna (Thunnus maccoyii; 10-21 kg) within sea pens in Australia.

AVMA Issues Statement On California Proposition 2
The largest and most respected veterinary association in the United States is cautioning that the California ballot initiative, Proposition 2, while admirable in its attempt to address the behavioral needs of animals, contains livestock confinement standards that may hurt the animals they are intended to help. The American Veterinary Medical Association (AVMA) issued a

World Rabies Day Reminder -- Vaccinate Pets
World Rabies Day (WRD) is just a year old-the inaugural event was held last September-but in just a year it has touched the lives of people in over 180 countries. Its message is simple; prevent rabies in humans. This year WRD is Sept. 28. Rabies is still a major threat worldwide. It kills over 55,000 people every year around the world and in the United States one to two people die annually. This year, U.S.

Social Learning Strategies And Predation Risk: Minnows Copy Only When Using Private Information Would Be Costly
Animals that live in changeable environments need information about their surroundings if they are to operate efficiently. They can gather information by exploring their surroundings themselves. This yields accurate information, but uses time and energy and can expose the animal to its predators. Alternatively they can gather 'cheap' information by copying others, but at the risk of gathering incorrect or outdated knowledge.
