“…The principal assumption made in any telemetry study is that the transmitter has no significant effect on the study animal (Gursky, 1998;Millspaugh and Marzluff, 2001). Some studies in other taxa suggest that carrying a transmitter may indeed have adverse effects, including energy costs (Pennycuick et al, 1990;Gessamen et al, 1991;Godfrey et al, 2003), increased stress (Creel et al, 1997;Suedkamp Wells et al, 2003), impaired mobility (Olsen et al, 1992;Putaala et al, 1997), changes in behavior, nutrition, and reproductive success (Livezey, 1990;Hubbard et al, 1998;Reed et al, 2005), and even mortality (Burger et al, 1991). The impact of transmitters in snakes has received little attention (Murray and Fuller, 2000).…”

ABSTRACT:The study of secretive snakes, such as rattlesnakes, has benefited from the use of radiotelemetry. However, the principal assumption in telemetry studies is that the transmitter has no significant effect on the study animal. To test the validity of this assumption, the physiologic and pathologic effects of intracoelomic implants were examined in a group of 24 eastern massasauga rattlesnakes (Sistrurus catenatus catenatus) in a laboratory setting over a period of 58 wk between March 2005 and April 2006. Inflammation and infection were evaluated using gross examination, histopathology, bacteriology, hematology, and plasma protein electrophoresis. Inflammation and infection occurred despite careful surgical procedures and advanced veterinary care. Four of 12 (33%) snakes developed extensive inflammatory response to the transmitter and associated anaerobic and gram-negative bacterial infections. Another four (33%) snakes showed mild inflammatory responses without infection. Reaction to the transmitters was reflected in changes in values for heterophils, monocytes, alpha-1, and beta globulin levels. Some conclusions reached in field studies using implanted radiotransmitters in snakes may be invalid if the implant influences the behavior or survival of the subject. Advances in attachment methods and transmitter coating technology may prevent some of the adverse effects associated with surgically implanted transmitters.

“…Obtaining these values prior to surgery may help reduce the mortality rate. A paper describing the surgical procedure for implantation of transmitters in Canvasbacks Aythya valisineria reports no abnormal behaviour or increased mortality after implanting devices with internal antennas [58]. Hupp et al [38] reported no post-surgery mortality in Lesser Canada Geese Branta canadensis parvipes tagged with radio transmitters with external antennas.…”

Reduction in adverse effects of tracking devices on waterfowl requires better measuring and reporting

Since the first studies in the mid-twentieth century, lightweight electronic tracking devices have been increasingly used to study waterfowl movements. With half a century of experience and growing sample sizes, it has become clear that the attachment of a tracking device can affect a bird's behaviour and fitness. This becomes problematic when it introduces uncertainty about whether the recorded data represent natural behaviour. Waterfowl may be particularly prone to tag effects, since many species are migratory and tracking devices can disrupt their waterproof plumage. The primary aim of this paper is to identify how tracking devices may affect waterfowl survival, migration and reproduction, and how better measuring and reporting of such effects can improve our understanding of the risks, providing a first step towards reducing their impact in future studies. We reviewed literature on electronic tracking of waterfowl to create an overview of currently recognized effects of harness-attached backpacks, implants, subcutaneous attachments and neck collars. Additionally, we analysed developments in the use of attachment methods, the weight of tracking devices relative to bird body mass, and the reporting rate of effects of tracking devices in 202 original tracking studies. We found that although the number of waterfowl tracking studies described in peer-reviewed literature has steeply increased over the past decades, reporting rates of potential effects have decreased from 65.0 to 26.5%. Meanwhile, the mean weight of the tracking devices relative to the bird's body mass remained stable around 2.0%. Major negative effects were reported in 17% of all studies and were found for all attachment methods. Overall, large differences exist in the occurrence and type of negative effects between species and studies, even if the same tracking methods were used. Inconsistent reporting of effects, lack of control groups to measure effects and incomplete descriptions of the methodology hamper the identification of factors contributing to these effects. To accomplish a reduction in adverse effects of tracking, it is necessary to improve the measuring and reporting of effects. We propose a framework for standardized reporting of methods in primary tracking studies and standardized protocols to measure effects of tracking devices on waterfowl.

In order to study the home range of the red-tongue viper snake (Gloydis ussuriensis) and the short-tailed viper snake (Gloydius saxatilis) belonging to the viperidae of squamat in Korea, we implanted radio-transmitters which were weighed less than 5% of individual mass in them and traced their location by radio-tracking. Surgeries for transmitter insertion were performed on 5 red-tongue viper snakes and 6 short-tailed viper snakes (total 11 individuals) and the average ratio of transmitter mass to body mass were 4.2% and 2.2%, respectively. After radio-transmitter implantation, all short-tailed viper snakes survived but 4 out of 5 red-tongue viper snakes did not survive during the convalescence stage, showing only 20% of survival rate. The results suggest that the ratio of transmitter mass to body mass should be less than 3.6% at least in these species, although previous studies have recommended various ranges from 1% to 7% as the acceptable ratios.
