All manuscripts will undergo external peer review. When reporting on captive held animals, please also consider the Guidelines for Use of Live Amphibians and Reptiles in Field Research In addition to conventional manuscripts, we will also publish brief notes Herpetoculture Notes based on limited observations of captive animals. These can be considered analogous to Natural History Notes and should be formatted the same way see link below. Subject matter examples include: Contributions are welcome from all persons who work with captive amphibians and reptiles, including zoo biologists, private herpetoculturists, and institutional professionals.
Amphibian chytrid fungi, Batrachochytrium dendrobatidis and B. Fungal infections in snakes and turtles are being detected more frequently in the last few years and may be primary or secondary infections leading to local losses. Ranaviruses also cause mass mortality, infecting both amphibians and reptiles, but have not yet been linked to large-scale declines.
For each of these pathogens, we know relatively little about the global distribution, host range, or impacts on host populations.13 Weirdest Looking Amphibians
To improve our understanding of the scope of this issue, we encourage submission of studies that illuminate the geographic distribution, host ranges, and impact of these pathogens on amphibian and reptile populations, including research on individual species or groups of species, wild or captive animals, native or non-native species, live animals or museum specimens, environmental samples, and, provided there is sufficient sampling 1reports of non-detections.
We ask authors to: Please include the following information in submissions as appropriate: We encourage researchers to conduct post-mortem examinations when possible to identify the cause of death when reporting mortalities. We aim to expedite the review and publication process! Please e-mail submissions directly to Associate Editor, Dr. Upon publication, we encourage authors to import their data to online disease reporting portals for rapid communication with researchers and natural resource managers.

With a sample of 10 an infection in one of four individuals could go undetected. We encourage researchers to collect sufficient samples so that negative results are meaningful. Electronic submission is strongly encouraged to expedite reviews and reduce costs to the society.

The species was considered a single unit and designated Special Concern in November Split into two populations in November The Calling population was designated Special Concern in November Status and reasons for designation Status: Special Concern Alpha-numeric code: Not applicable Reasons for designation: Almost the entire range of the calling population is within Canada. The toads are particularly sensitive to emerging skin disease caused by the amphibian chytrid fungus, which has been linked to global amphibian declines.
This species is relatively intolerant of urban expansion, conversion of habitat for agricultural use, and habitat fragmentation resulting from resource extraction and road networks. Life history characteristics, including infrequent breeding by females, aggregation at communal, traditionally used breeding sites, and migrations to and from breeding sites, make populations vulnerable to habitat degradation and fragmentation.

The species remains widespread throughout much of their historic range in Alberta and may be expanding their range eastwards. However, declines are suspected and projected based on known vulnerabilities and threats. Applicability of criteria Criterion A Decline in total number of mature individuals: Not applicable; population trends are unknown. Criterion B Small distribution range and decline or fluctuation: Criterion C Small and declining number of mature individuals: Not applicable; population is larger than threshold values, and trends are unknown.
Criterion D Very small or restricted total population: Not applicable; population size is unknown but much larger than threshold values; number of locations and IAO exceed guidelines for D2 Threatened. Criterion E Quantitative analysis: This is evidence for two designatable units in Canada.
Surveys have improved knowledge of the extent of occurrence and area of occupancy. It arose from the need for a single, official, scientifically sound, national listing of wildlife species at risk. Species designated at meetings of the full committee are added to the list.
Designations are made on native species for the following taxonomic groups:
