Abstract Emerging infectious diseases are an increasingly prominent threat to biodiversity. However, traditional methods in conservation generally have limited efficacy the face of disease threats. Ironically, although unintentional human movement species has facilitated spread pathogens, intentional translocations a promising approach combatting threats under certain circumstances. Here, we summarize two decades published literature on Australian frogs threatened by chytridiomycosis—a...
<ns3:p>The Southern Corroboree frog (<ns3:italic>Pseudophryne corroboree</ns3:italic>; Anura; Myobatrachidae) is a Critically Endangered amphibian, according to the IUCN, and endemic Snowy Mountains region of Kosciuszko National Park in New South Wales, Australia. This species has been driven functional extinction by introduction fungal disease, chytridiomycosis. Here we provide first reference genome for <ns3:italic>P. corroboree</ns3:italic>. Using PacBio HiFi sequencing, Arima Hi-C,...
More than a third of the world’s amphibian species are listed as Threatened or Extinct, with recent assessment identifying 45 Australian frogs (18.4% currently recognised species) ‘Threatened’ based on IUCN criteria. We applied structured expert elicitation to 26 assessed Critically Endangered and estimate their probability extinction by 2040. also investigated whether participant experience (measured self-assigned categorical score, i.e. ‘expert’ ‘non-expert’) influenced estimates....
Abstract The amphibian chytrid fungal pathogen ( Batrachochytrium dendrobatidis , henceforth Bd ) has had a devastating impact on biodiversity, causing the decline or extinction of over 500 species. Yet, our understanding transmission pathways remains incomplete, in particular for host species with weak aquatic associations, and between reservoir susceptible We examined from potential to potentially critically endangered host; directly assessing capacity former transmit susceptibility latter...
Abstract Temperature and food availability are known to independently trigger phenotypic change in ectotherms, but the interactive effects between these factors have rarely been considered. This study investigates independent of water temperature on larval growth development critically endangered Baw frog, Philoria frosti. Larvae were reared at low (12°C) or high (17°C) absence presence substrate that controlled availability, body size time metamorphosis quantified. Growth larvae was...
Reproductive technologies (RTs) can assist integrated conservation breeding programs to attain propagation targets and manage genetic diversity more effectively. While the application of RTs enhance management threatened amphibians has lagged behind that other taxonomic groups, a recent surge in research is narrowing divide. The present study reports on first (hormone-induced spawning, hormone-induced sperm-release, sperm cryopreservation) critically endangered Baw frog,
This paper presents the design and implementation of a motion detection algorithm for processing video sequences captured by purpose-built camera trap, removing unwanted frames, reducing size sequences. The trap is used to create dataset containing H.264 critically endangered Baw Frog Philoria frosti. A method based on optical flow Farneback then developed reduce detecting frames that contain moving frogs, keeping storing detected discarding do not frogs. Twenty total 13770 are in this...
Abstract In recent years, the potential to locate endangered animals using scent trained detection dogs (conservation dogs) has gained attention. Among vertebrates, conservation have demonstrated a remarkable capacity detect of mammals, reptiles, and birds, but their use in detecting amphibians is only beginning be explored. A lack work this area surprising given that are declining faster than any other vertebrate taxa. Moreover, generally small, highly cryptic breed complex habitats, making...
Conservation breeding programs (CBPs) are often the lifeline between extinction and survival for many imperilled amphibian species. With goal of recovering wild populations, CBP success is reliant on their ability to successfully manage ex situ populations over time, breed viable offspring, maintain genetic diversity adaptive potential. Reproductive technologies have emerged as an important tool in conservation toolkit allow managers improve reproductive output management, use expanding. To...
Abstract Chytridiomycosis poses a significant extinction threat to many amphibians, including the critically endangered southern corroboree frog ( Pseudophryne ). Captive breeding programs have become essential maintain populations while effective long-term conservation strategies are developed. Understanding variation in susceptibility chytridiomycosis within this species is exploring potential for selective enhance disease resistance. In study, we conducted large-scale Batrachochytrium...
Wildlife detection dog teams have been widely demonstrated to be a highly sensitive and effective monitoring method. Sourcing suitable samples of target species with which train dogs can challenging. An alternative is training on similar (or multiple species), the aim generalising desired or category (e.g. ‘frog’). If successful, this approach could allow for not available previously discovered, permit data collected species, if desirable. Our study aims were determine trained generalise...
