(Press-News.org) Based on ten years of fieldwork in the Tetons of Wyoming, WCS Conservation Biologist, University of Montana Professor and study author Dr. Joel Berger looked at whether body size of juvenile moose and maternal presence were related to survival of the young animals. In animals from elk to lizards and fish, size matters, and larger individuals enjoy a survival advantage. However, results of Berger's study showed that for juvenile moose, body mass had no significant effect on overwinter survival. Maternal presence did.
The study, "Estimation of Body-Size Traits by Photogrammetry in Large Mammals to Inform Conservation" appears in the early view section of the on-line edition of the journal Conservation Biology.
The study found that orphaned moose in their first winter were subjected to 8 to 47 times more aggression from adult moose than were young moose whose mothers were present. Overall, the survival of orphan calves was about 8 times lower than those with mothers.
Along with facing more aggression from kicking by adult females and being displaced from the best feeding areas, Berger theorized that orphans incur greater metabolic costs and expend more energy in deep snow. Why orphans were attacked more was not clear, but Berger raised the possibility that mothers were trying to maintain more resources for their own offspring.
"These findings highlight the importance of maternal presence rather than body size and suggest policy changes may be warranted in how harvest quotas are set," said Berger. "In some circumstances, the shooting of mothers with young has been permitted under the assumption that calf survival is minimally affected. Clearly, that is not the case."
In another development from the study, Berger pioneered a new method to estimate the size of juveniles without resorting to immobilization by darting or netting by helicopters – both methods that are stressful to wildlife. Instead, Berger used photogrammetry—a process of using photographs to determine the properties of objects. Digitally measuring head sizes on photographs enabled estimation of juvenile body mass in a quick and non-invasive fashion.
Berger said, "Other methods of acquiring data on large animals are exhaustive, expensive and more invasive. Photogrammetric assessment has shown to be accurate, widely deployable and much easier on the animals and scientists, and the findings in this study illustrate the method can be used to inform conservation planning."

Virus detector harnesses ring of light in 'whispering gallery mode'
2012-08-24
By affixing nanoscale gold spheres onto a microscopic bead of glass, researchers have created a super-sensor that can detect even single samples of the smallest known viruses. The sensor uses a peculiar behavior of light known as "whispering gallery mode," named after the famous circular gallery in St. Paul's Cathedral in London, where a whisper near the wall can be heard around the gallery.
In a similar way, waves of light are sent whirling around the inside of a small glass bead, resonating at a specific frequency. Just as a small object on a vibrating violin string ...
Wind concentrates pollutants with unexpected order in an urban environment
2012-08-24
Cities – with their concrete canyons, isolated greenery, and congested traffic – create seemingly chaotic and often powerful wind patterns known as urban flows. Carried on these winds are a variety of environmental hazards, including exhaust particles, diesel fumes, chemical residues, ozone, and the simple dust and dander produced by dense populations.
In a paper published in the American Institute of Physics (AIP) journal Physics of Fluids, researchers present the unexpected finding that pollutant particles, rather than scattering randomly, prefer to accumulate in specific ...
Moffitt Cancer Center researchers and colleagues identify PHF20, a regulator of gene P53
2012-08-24
Researchers at Moffitt Cancer Center and colleagues have identified PHF20, a novel transcriptional factor, and clarified its role in maintaining the stability and transcription of p53, a gene that allows for both normal cell growth and tumor suppression. PHF20, the researchers found, plays a previously unknown and unique role in regulating p53.
When p53 is activated, it can mend DNA damage and eliminate cancer cells by binding to DNA. How p53 maintains its basal level and becomes activated remain elusive, but identifying transcription factor PHF20 and understanding its ...
