Pit Tagging

ABSTRACTSymbiotic bacterial communities play a key role in protecting amphibians from infectious diseases including chytridiomycosis, caused by the pathogenic fungusBatrachochytrium dendrobatidis. Events that lead to the disruption of the bacterial community may have implications for the susceptibility of amphibians to such diseases. Amphibians are often marked both in the wild and in captivity for a variety of reasons, and although existing literature indicates that marking techniques have few negative effects, the response of cutaneous microbial communities has not yet been investigated. Here we determine the effects of passive integrated transponder (PIT) tagging on culturable cutaneous microbial communities of captive Morelet's tree frogs (Agalychnis moreletii) and assess the isolated bacterial strains for anti-B. dendrobatidisactivityin vitro. We find that PIT tagging causes a major disruption to the bacterial community associated with the skin of frogs (∼12-fold increase in abundance), as well as a concurrent proliferation in resident fungi (up to ∼200-fold increase). Handling also caused a disruption the bacterial community, although to a lesser extent than PIT tagging. However, the effects of both tagging and handling were temporary, and after 2 weeks, the bacterial communities were similar to their original compositions. We also identify two bacterial strains that inhibitB. dendrobatidis, one of which increased in abundance on PIT-tagged frogs at 1 day postmarking, while the other was unaffected. These results show that PIT tagging has previously unobserved consequences for cutaneous microbial communities of frogs and may be particularly relevant for studies that intend to use PIT tagging to identify individuals involved in trials to develop probiotic treatments.

Pit Tagging

Context Passive integrated transponder (PIT) technology allows for permanent and unambiguous marking of animals and has recently been adapted for locating tagged individuals in the field with portable detection systems. Aims We seek to assess the effects of PIT tagging on the growth and survival of plethodontid salamanders in the laboratory and to evaluate the effectiveness of this method for subterranean detection of salamanders in the field. Methods In a laboratory experiment, we assigned 36 Plethodon shermani to either a PIT tag or control group and compared survival and growth rates over the course of 9 weeks. For the field study, we implanted six Plethodon metcalfi with PIT tags and conducted surveys so as to determine their below-ground positions with a portable detector. Key results We found no effect of PIT tagging on either growth or survival in the laboratory. In the field, PIT telemetry resulted in an overall detection efficiency of 44%, with nighttime surveys yielding a greater detection efficiency than daytime surveys. This technique provided a significant improvement over traditional hand-capture because detected salamanders were rarely visible on the ground surface. Key conclusions Our study indicates that even these relatively small-bodied salamanders (range: 2.14–5.18 g) are capable of bearing PIT tag implants and confirms the results of previous studies that found no effect of PIT tagging on the health or survival of amphibians. This study further demonstrates that the use of a portable PIT detector can be an effective method for locating below-ground salamanders. Implications Because of the small size and long lifespan of PIT tags, we believe portable PIT detectors can provide researchers with an unprecedented level of detail for studies of the movement behaviour, spatial ecology and management of species that are small or otherwise challenging to detect and monitor with other techniques.

Abstract The developmental pathways of the offspring of three groups of trout, Salmo trutta L., with known life histories were compared: one group from a freshwater resident population and two groups from an anadromous population (fish that have smoltified and fish that have not). The fish were hybridized within a group, and 27 families were obtained and reared mixed in two tanks. Tracking fish specimens was possible thanks to individual passive integrated transponder (PIT) tagging. All families followed different life pathways. Faster growth favored early smoltification and maturation at the age of 1+ in males that had not smoltified. In addition, both processes were clearly also influenced by inherited factors. Fish of freshwater resident origin smoltified more infrequently, and males matured earlier than did fish from the migratory population. The offspring of parents from the migratory population, which did smoltify during their individual histories, smoltified early (in the second year) more often than offspring of non-smoltified members of the population.
