The gold-spotted pond frog (Pelophylax chosenicus) is an endangered amphibian species in South Korea. In order to obtain ecological information regarding the gold-spotted pond frog’s habitat environment and biological interactions, we applied stable isotope analysis to quantify the ecological niche space (ENS) of frogs including black-spotted pond frogs (P. nigromaculatus) and bullfrogs (Lithobates catesbeianus) within the food web of two different habitats—an ecological wetland park and a rice paddy. The gold-spotted pond frog population exhibited a broader ENS in the ecological wetland park

Annotation:

Some animals, such as the bombardier beetles (Coleoptera: Carabidae: Brachinini), have evolved chemical defences against predators. When attacked, bombardier beetles can discharge noxious chemicals at temperatures of approximately 100 °C from the tip of their abdomens, “bombing” their attackers. Although many studies to date have investigated how bombardier beetles discharge defensive chemicals against predators, relatively little research has examined how predators modify their attacks on bombardier beetles to avoid being bombed. In this study, I observed the black-spotted pond frog Pelophyla

SUMMARY Gliding has evolved independently in two families of tree frog. Tree frogs glide to descend rapidly to mating sites over temporary pools on the forest floor or to escape predators. The physical mechanisms used by frogs to glide and maneuver were investigated using a combination of observations of live frogs (Polypedates dennysi) gliding in a tilted wind-tunnel and aerodynamic forces and torques measured from physical models of tree frogs in a wind-tunnel. Tree frogs maneuvered in the tilted wind-tunnel using two different turning mechanisms: a banked turn (the frog rolls into the turn)

Annotation:

Ecological corridors are an essential element in conserving the biodiversity and proper functioning of ecosystems. Without their connectivity, a very large number of species would not have access to all of the habitats needed for their life cycles. Although the concept of an ecological corridor has been discussed for many years, few studies on ecological corridors for frogs have been conducted. Frogs are often considered to be a keystone species. They are a good indicator of habitat health, and they are often the first to be harmed by pollution or ecosystem deterioration. However, there have b

Frogs and toads belong to the same order, Anura, but toads usually have rough and bumpy skin like those in the Bufonidae family. This study aims to study the morphological characteristics of male frog sperm cells using the galli mainini method, using pregnant women's urine containing the hormone human Chorionic Gonadotropin (hCG) to stimulate sperm production. Urine is injected into the frog's abdominal membrane, and after 30 minutes, the frog is stimulated to excrete urine containing sperm. The results showed that the length of Bufonidae frog spermatozoa ranged from 32.54 μm to 73.31 μm with

The frog-inspired jumping robot is an interesting topic in the field of biomechanics and bionics. However, due to the frog’s explosive movement and large range of joint motion, it is very difficult to make their structure completely bionic. To obtain the optimal jumping motion model, the musculoskeletal structure, jumping movement mechanism, and characteristics of frogs are first systematically analyzed, and the corresponding structural and kinematic parameters are obtained. Based on biological characteristics, a model of the articular bone structure is created, which can fully describe the fe

Abstract The gopher frog Lithobates capito is one of the most terrestrial frogs in the southeastern United States and often inhabits gopher tortoise burrows Gopherus polyphemus outside of the breeding season. Gopher frog populations have declined, and the species is under review for listing as threatened or endangered under the U.S. Endangered Species Act. Much of our knowledge on the status of gopher frogs is based on detections of larvae at breeding wetlands, which can be challenging because of environmental variability and provides no information on the terrestrial life stages of the specie

Abstract ContextWe recently estimated the numbers of reptiles, birds and mammals killed by cats (Felis catus) in Australia, with these assessments providing further evidence that cats have significant impacts on Australian wildlife. No previous studies have estimated the numbers of frogs killed by cats in Australia and there is limited comparable information from elsewhere in the world. AimsWe sought to (1) estimate the numbers of frogs killed by cats in Australia and (2) compile a list of Australian frog species known to be killed by cats.

This chapter discusses the hunt for the frog that sings like a bird in the vast mountainous forests of Pu Hoat Nature Reserve in northwest Nghe An Province, Vietnam. It elaborates on the fieldwork of recording the calling of frogs that allowed researchers to identify each one. One of the frogs was Quang's Tree Frog (Gracixalus quangi) which had a unique call consisting of high-pitched chirps, whistles, and chirps similar to a bird. Thus, the tiny turquoise frog was coined “loài ếch có tiếng kêu nhu tiếng chim hót,” or “the frog that sings like a bird.” The chapter also notes the frog's cluster

The cane toad is highly adaptable around humans and can thrive in agricultural fields, golf courses, residential developments, and along canals, among other disturbed habitats.

Science reviews are an essential cornerstone of all excellent science programs and are a requirement of monitoring programs within the Inventory and Monitoring Division of the National Park Service (NPS). Science reviews provide necessary professional critique of objectives, study design, data collection, analysis, scientific interpretation, and how effectively information is transferred to target audiences. Additionally, reviews can help identify opportunities to cooperate more effectively with interested and vested partners to expand the impacts of collective findings across larger landscape

The management and recovery of threatened and endangered amphibians on Department of Defense (DoD) lands relies on an understanding of their distribution and abundance. Fortunately, most anuran species can be surveyed acoustically using vocalizations during the breeding season. This work demonstrated the use of subsurface passive acoustic monitoring (SPAM) to survey for rare underwater-calling, at-risk anuran species on DoD installations. We evaluated the performance of SPAM relative to traditional passive acoustic monitoring (PAM) (microphone) and human manual calling survey (MCS) methods. Re

This study used a combination of field surveys, historical data, literature review, and formal methods to assess the biodiversity and habitat integrity of vertebrates, excluding mammals at Barrett?s Farm unit (BFU). A one season full inventory of the herpetofauna was completed in 2023. The herpetological survey documented ten species commonly found in Massachusetts (4 frogs, 1 toad, 2 salamanders, 1 snake and 2 turtles), with only one species (Lithobates pipiens, Leopard Frog) being seen in large numbers. Several species (Ambystoma maculatum, Spotted Salamander; Dryophytes versicolor, Gray Tre
