Anura - Science topic
An order of the class Amphibia, which includes several families of frogs and toads. They are characterized by well developed hind limbs adapted for jumping, fused head and trunk and webbed toes. The term "toad" is ambiguous and is properly applied only to the family Bufonidae.
Questions related to Anura
Does anyone know roughly what percent of anurans or urodeles exhibit direct development vs having a larval stage? I've been trying to find numbers for both groups but no luck so far.
Recently, I got an invitation from the editor of 'Eliva Press'. The editor mentioned one of my recently published articles and invited me to publish a book on those works. I want to know whether 'Eliva Press' is legitimate? Is it worth publishing a book with them? I am copying the whole email for your reference below.
Thanks in advance.

Dear Dr. Md Mizanur Rahman ,
My name is XX (I replaced the name) and I am editor at Eliva Press. I went through your list of recent publications and it is impressive. We are interested in publishing a book of your works, including this paper: "Confirmation of the Applicability of Skeletochronology and Estimating the Age Structure of Kaloula borealis (Microhylidae: Anura) at Lake Sihwa, South Korea".
We specialize in publication and dissemination of academic books. The publication is free for our authors. You will retain copyrights and earn up to 50% royalties. In addition, the book will be distributed through Amazon Distribution Channels and many more.
Do you want to find more about our publishing services?
Your reply would be greatly appreciated.

I am carrying out a phylogenetic analysis on the relationships of several families within Anura and was planning on using cytb and COI in my analysis but I am not sure whether I should be choosing less conserved genes?
Hello everyone. I represent a small group of students from Maastricht University in the Netherlands. We are currently working on a project regarding toe-tapping behavior in frogs and toads (see https://www.youtube.com/watch?v=gl_A4UosQjw). We are collecting as much information as possible regarding it in order to try to shed some light on this very understudied phenomenon. If you've ever observed it and could spare a few minutes of your time to help us in our research, please fill out our questionnaire or share your knowledge with us. Any input is greatly appreciated.
Thank you for your time and happy herping.✌️
I would like to analyse the shape of parotoid glands between two species by using landmarks. But because of assymetries between glands of an individual (i have observed assymetries in many of my samples) i m doubtful to try it. I am also inexperienced in this approach. So,could anyone inform me whether it is an appliable idea to analyse the shape of parotoid glands ?
I'm working on the osteology of fossil anuran amphibians. Please let me know has the radioulna some diagnostic characters in these animals (i.e. is it possible to determine this bone up to species/genus level etc.)? I will be very thankful for your comments.
As above. Need to take some close-up reference photographs of a Spadefoot Toad fixed in 70% ethanol and was wondering whether it is possible to remove from solution without causing major damage to the tissues. Is this possible?
This frog species has been found in my garden at Rajiv Gandhi University Campus, Itanagar, Arunachal Pradesh (India). As I am a bit poor in taxonomy of frogs I do hope experts in this field may like to help me in identifying the species.
We are sampling tadpoles in wetlands to determine mortality as a function of a few different biotic and abiotic variables. We know (roughly) how many tadpoles are in the wetlands because we count either tadpoles or egg masses. We use a 0.5 m^2 pipe sampler to collect data and estimate abundance using the methods for plot sampling from Borchers et al. 2002 on estimating animal abundance.
I am concerned we are underestimating abundance in large wetlands because we can only sample a set amount which means the probability of sampling tadpoles is lower in larger wetlands. I believe the probability of detection for the area in that we sample is 1 or very close to it (as required for the assumptions of plot sampling) but as wetland size increases, the likelihood of actually sampling tadpoles decreases.
Does anyone have any suggestions on how to deal with what the influence of differences in wetland size (via different detection probabilities) might be on our abundance estimates?
Anuran tadpoles respond to chemical cues of predation reducing foraging and swimming activity. In many cases this behavior is produced by a predation event releasing different kind of cues, in particular alarm cues, coming from tadpole itself, seem to play a key role in elicit antipredatory responses, even if they often need to be associated to kairomone (from predator) to have the whole response.
