A body condition score (BCS) may provide information on the health or production potential of an animal; it may also reflect the suitability of the environment to maintain an animal population. Thus assessing the BCS of Asian elephants is important for their management. There is a need for a robust BCS applicable to both wild and captive elephants of all age categories based on the minimum and maximum possible subcutaneous body fat and muscle deposits. The visually based system for scoring the body condition of elephants presented here satisfies these criteria and is quick, inexpensive, non-invasive and user-friendly in the field. The BCS scale correlates (P<0.05) with morphometric indices such as weight, girth, and skin fold measures. Zoo Biol. 34:53-59, 2015. © 2014 Wiley Periodicals, Inc.

Longitudinal urine samples were collected from Asian and African elephants to assess sample processing and immunoassay techniques for monitoring adrenal activity. Temporal profiles of urinary cortisol measured by RIA and EIA, with and without dichloromethane extraction, were similar; all correlation coefficients were >0.90. However, based on regression analyses, cortisol immunoactivity in extracted samples was only 72-81% of that of unextracted values. Within assay technique, RIA values were only 74-81% of EIA values. Collection of 24-hr urine samples demonstrated a clear diurnal pattern of glucocorticoid excretion, with the lowest concentrations observed just before midnight and peak concentrations occurring around 0600-0800 hr. These results indicate that elephants fit the pattern of a diurnal species, and that glucocorticoid production is affected by a sleep-wake cycle similar to that described for other terrestrial mammals. Cortisol can be measured in both extracted and unextracted urine using RIA and EIA methodologies. However, unexplained differences in quantitative results suggest there may be sample matrix effects and that data generated using different techniques may not be directly comparable or interchangeable. © 2009 Wiley-Liss, Inc.

We developed a non-invasive DNA sampling method and 15 tetranucleotide microsatellite markers for Texas horned lizards (Phrynosoma cornutum). Swabbing the cloaca with a small cotton swab and preserving the cells in lysis buffer was an effective method to obtain tissue for DNA extraction. Loci were highly polymorphic with 8-25 alleles and observed heterozygosity was high (0.71-0.96). Some of these loci can also be used for round-tailed horned lizards (P. modestum). © Springer Science+Business Media B.V. 2011.

The Thursday-morning hailstorms last week that pounded cars and rolled across North Texas could lead to $300 million in vehicle repairs alone. Mark Hanna, a spokesperson for the Insurance Council of Texas, said that an estimated 50,000 vehicles were battered by the storms from Fort Worth to Arlington. “This is a catastrophic event for us,” Hanna says in a Forth Worth Star-Telegram report of the hail, which fell in two occasions and varied from the size of blueberries to tennis balls. The number of damaged roofs could be around one-third of the number of damaged vehicles, Hanna added, although the cost of their repair could be double that of the vehicles’. Reports have it that insurance firm State Farm already received at least 3,850 car claims and 1,480 home claims. Last Sunday, it opened its vehicle assess sites to address the claims, and will open three more by the week’s end. The storms left the streets with debris, leaves, and some remnants of damaged structures. Even the West Division headquarters of Fort Worth Police Department was not spared, just like the Fort Worth Zoo where eight birds and five flamingos were killed. But there were also emerging winners from the damage, such as companies like Auto Glass Now – located in west Fort Worth off Interstate 30 – that already provided hundreds of estimates for affected windows. The weekend had also been likely been a lucrative one for AAA Glass, which worked on cars or replaced home windows. Hail occurs when updrafts in thunderstorms become carriers of raindrops upward into very cold areas where they freeze into ice. Hail can damage not only structures but also livestock and crops. Research focuses on accurate prediction and detection of hailstorms to give those who run in the path of the storm enough preparation time to seek shelter and protect their personal property.

Eight exotic birds were killed by hail which also damaged the canopy of a carousel at the Fort Worth Zoo, as shown in this handout photo taken in Fort Worth, Texas on March 17, 2016, and provided by the Fort Worth Zoo.

Eight exotic birds were killed by hail which also damaged the canopy of a carousel at the Fort Worth Zoo as shown in this handout photo taken in Fort Worth, Texas on March 17, 2016, and provided by the Fort Worth Zoo. Eight exotic birds were killed at the Fort Worth Zoo on Thursday by a violent hail storm that dropped ice pellets the size of golf balls, a zoo spokeswoman said. Among the birds killed were five flamingos, a pelican, an ibis and a black-necked swan chick, said Alexis Wilson, the zoo's director of communications. The hail that hit at around 6:30 a.m. also damaged roofs and skylights, she said, but almost all of the other residents at the 7,000-animal zoo were unaffected by the hail.
