Questions related to Primatology
Hello colleagues, in the coming months I will be investigating the presence of drills (Mandrillus leucophaeus) in an area where they have not been seen for years (Pico Basilé Natural Park, Bioko, Equatorial Guinea). It is a rainforest, with altitudes of about 1000-2000 meters. Obviously, I have considered line transect surveys, as they have been widely used for estimating abundance of primate populations. However, there are some issues to consider.
1. It is a very steep area, which will prevent me from drawing completely straight transects.
2. I will perhaps not even find the species. Therefore, as it has been done with the species in other areas, indirect evidence such as fecal remains will be sought. I also thought it appropriate to incorporate signs of human activity into the data (cartridges, rubbish,...) as bushmeat hunting is the main cause of biodiversity loss on the island.
3. I will also have trap cameras, which I intended to strategically place in front of fig trees, a key food in the diet of the species.
I am just starting in the field. I have done fieldwork before, but related to other very different taxa in a very different environment. I've been checking the literature but still, I wanted to ask you to recommend me a study that has used similar methods (nonlinear transects), or that has considered fecal remains to assess the presence of a primate species (I don't even want to say density, because I do not know or if we find them). Or maybe some other publication that explains how to propose different sampling methods according to the field conditions, how to calculate the distance between transects, etc. Or any other key issues they deem appropriate to explain to me.
Thank you so much!
I'm am traveling to Laos to work with rescued animals and would like to help enhance the enrichment program for the animals to keep them stimulated while they recover in captivity.
I am writing my MSc thesis about vocal communication in woolly monkeys and I want to make a general description of their different types of calls. I want to obtain various acoustic parameters such as duration, frequency range, low frequency, high frequency, maximum amplitude, average frequency, initial frequency, and final frequency. Hence, I have to analyse my recordings using SoundRuler, but I've never used this software before. I've read the instructions but I have some questions anyway.
- I recorded in stereo, so when I introduce the recording in the software, it asks me if I want to analyse left or right channel. Can I analyse both separately and then calculate the mean of both channels?
- Also, when I introduce the recording, I mark the section that I want to analyse using green bars. Once this section is marked, I proceed to do the analysis. Is it as easy as clicking the "manual" button? When I do it, it appears a table with the different values of the parameters, but I don't know if it is as "simple" as that.
That's all at the moment. Thank you for your answers!
Bit of a strange one, I am doing a critical analysis of the use of line transects in primate abundance studies. I have found many papers which have a robust study design with many replications etc. However, I am looking for papers which have a questionable study design i.e low replication/lack of randomisation/missing key assumptions. Any suggestions?
I am having difficulty finding ways of getting camera traps set up at canopy level (looking for primates) without tree climbing equipment. Any suggestions?
I need to find useful information about behavioral imprinting in non-human primates because the literature that I have reviewed does not show a conclusion about the existence of imprinting in these species.
Looking for any published data that could be used to determine body fat percentages and muscle mass in nonhuman anthropoids as a function of sex. The data for a particular species could be obtained from separate sources.
Very good, I am currently in research practices Coast gorilla at the zoo in Barcelona, and would like to know behavior that catches my attention:
- Why are gorillas, especially the dominant male, and sometimes sub-adults, walking straight ahead, stop, look, and they turn around with your body, to continue in the same direction opposite?
They do it very often, to walk straight, stop, give that swing with the body and then continue in the same direction or near that direction ... It is curious because they do.
THANKS FOR EVERYTHING
We survey Bengal Slow Loris in several fixed transects in a forest of Northeastern Bangladesh, while we regularly encounter Particloloured Flying Squirrel (Hylopetes alboniger) and noted down with GPS co-ordinate. Surveys in the transect are not equal. Hence, a one year (at least 4 nights in a month) effort to the opportunistic encounters can reveal the accurate population size of the squirrel in the area?
If possible let me know data analysis patterns in estimating total population from the direct observations.
Good scientists. What is the difference between white and brown iris iris or brown in chimpanzees? It is possible that white iris around the eye is a pattern of greater intelligence and higher rank over another individual?
Thanks for everything, I am studying a postgraduate / master of primatology and am new to this.
I would like to train juvenile and adult baboons to use a hand dynamometer built for humans. The purpose is to test grip strength between control and experimental groups. I haven't been able to find any other studies doing this with large bodied nonhuman primates. I am trying to find background research to guide my study design.
Hi all, I need for a study the weight average of hands of Orangutans, Bonobos and Western Lowland Gorilla. Does anyone know where I can find these data please?
Thank you for your answers.
How can I calculate p value for rate analysis of particular lineage? I have used Mega 6 for estimation of dN/dS ratio ?
Kindly guide me.
I have used 5 primates (human. Chimp, gorilla etc) orthologous sequence for rate analysis (dN/dS ) using Li Wu Lu method. Now I want to calculate P value for estimated dN/dS of each terminal branch (like for human branch).
I used the following method is it correct?
I wanted to calculate p value for dN/dS ratio of human lineage. I used z test formula mentioned in mega manual i.e. Z = (dN - dS) / SQRT(Var(dS) + Var(dN)).
In (dN - dS), I placed human dN and dS value. For calculation of variance, I used dN and dS value of all the terminal and ancestral lineage branches, e,g Var(human dN, chimpanzee dN, gorilla dN, orangutan dN, human-chimp ancestor dN, human-chimp-gorilla ancestor dN ).
After getting z value I calculated p value using online software.
There must be a management protocol specifically for primates in biological collections. I cannot find them ...
Thanks in Advance!
Hi, i am working with a new a rare specie of primate in Colombia named Callicebus caquetensis recently described.
Its is located in a high fragmented area and there are estimations of poblational size which barely reach 500 viable individuals.
I must stand a methodology for the study of its poblational density and i am not sure about the usual line transect method.
THanks in advance.
I am studying Macaca nemestrina on Peninsular Malaysia and was wondering whether there is any census data available on their rough population size?
To avoid wasting paper and time on data entry, I'd like to digitise the collection of my observational data of chimpanzees. I only have access to apple products unfortunately, as I know Pendragon Forms can do this for windows-based tablets and palm devices.
What I am envisaging is an app which would allow me to create drop-down menus for entering data into forms (e.g. focal individual, their nearest neighbour, distance to neighbour), and have it compile each observation into a single database. There doesn't seem to be anything specific to behavioural data collection available on iTunes, but I imagine a highly customisable survey-taking software would do the job just as well. I don't mind paying for something that fits the bill, but a subscription based service is not viable.
If anyone knows of something like this then I'd greatly appreciate hearing about it.
Wild great apes commonly make their night nests around dusk and usually rise again at dawn, but do they sleep through the night? Does sleep come later in the evening, following a period of rest, or is there a period of wakefulness in the middle of the night? What is known about captive great ape sleep patterns? These questions may help us to understand the segmented sleep patterns thought to have been practiced by people in the West before Industrial Revolution.
Are there records of a non-human primate, pregnant with twins or more, giving birth to one offspring and then stopping labor so that the birth of a subsequent infant is delayed for multiple days (or even multiple months)? This is well-referenced in humans and is documented in medical literature, but I am asking specifically about recorded instances in non-human primates (prosimians in particular).
I'm looking for incidences of both successes and failures, particularly with apes. I am aware for the success of the golden lion tamarin reintroduction program. Others I know of (no sources though) are the Perth Zoo orangutan reintroductions (Temara - success?), Semeru (failure, died snakebite). Also the recent problems with the Aspinall gorilla reintroductions (details, news sources would help here). Any additional info appreciated.
We are trying to find some tutorial, guide, or video explaining how to use and run Generalized Linear Mixed Models (GLMM) in SPSS software. We are working in animal behavior (primatology) and we need to analyze a 8 years' longitudinal database about the re-socialization and rehabilitation process of a chimpanzee sample.
Do you know where to get it? Some advice?
There are many contradictions in the literature as to the origin of the omo-cervicalis (aka, atlanto-cervicalis, levator claviculae) muscle in non-human primates. Miller 1932 reports it's on the spinous process but all images (including his) appear to depict its origin on the lateral aspect of the pars interarticularis. Any informed knowledge on this from dissection or otherwise? Not from the usual literature citing Miller (ie., Aiello, Wood).
The Little Fireface Project in Java, Indonesia aims to conserve the Critically Endangered Javan slow loris (Nycticebus javanicus). We are currently evaluating the use of our slow loris bridges. So far we have found that 3 bridges were badly placed as they were not used for 4 months whereas a bridge that we placed well was used within 2 weeks by lorises and tree shrews. We put up the bridges as one of our study lorises dispersed into the village where she was most likely electrocuted. We would like to know more about the wildlife bridges used by other projects.
I hope that you can help me fill in the following questionnaire about wildlife bridges and send it on to any other organizations that you know who are using these bridges.
I have some histological tooth sections marked Mandrillus but they are quite a bit smaller than Madrillus sphinx teeth. Are Mandrillus leucophaeus teeth smaller? I'm having a terrible time finding any data on this.
I am conducting an analysis of the factors that influence the site selection of nests of all of the great apes, therefore I would greatly appreciate any advice on where I can find some data sets on this topic. Some of the factors I intend to look at include tree species, height of lowest branch from ground level, height of nest from ground level, distance from nearest food and water sources and direction of travel before and after nesting. Thanks for any help in advance!
It's true that mental illness stigma is quiet prevalence in the United States, and I'm curious whether it happens to the animals as well. However, I do not have a background in psychology, and I'd really appreciate it if someone could give me some references.
I'm organizing a symposium for the 2014 American Society of Primatologists meeting, exploring primate-human interface, interaction, & relationships across settings. I will be specifically addressing primate-human interactions & relationships in zoos. I am familiar with the findings of visitor effect studies (i.e. majority report humans = stressful). However, I'd like to examine the costs & benefits of interactions from multiple perspectives, e.g., animal welfare & behavior, visitor experience, keeper experience, research design & outcomes. I'd like to compile a benefit/cost list even if people do not have the research data to support these - personal experience is great.
I have data on maternal kinship for chimpanzee groups and I am interested in looking at social relationships between group members. It is likely that close kin members will interact more often than non/distant kin members. Is there a measurement that scans or perhaps scores kinship on a scale (i..e mother-offspring is a stronger relationship than say aunt-niece)? We don't have genetic data on the chimpanzees, but we do know maternal kinships because they are captive.
I have seen a coefficient of relatedness in the literature, and was wondering how is works, and if it is the best approach.
I am comparing the honing complex of apes but cannot find a detailed description, or even a general description for the bonobo.
I'm looking for any evidence (via direct observation of attack or scat analysis) that this big cat does eat sympatric monkeys, and especially macaques. Any references or personal observations to share with me?
I am conducting my PhD research in Primate Conservation at Oxford Brookes University, UK. I am focused on the Chlorocebus genus and the conflict that arises when these adaptable monkeys live in close proximity to humans. Part of my research consists of developing distribution maps that highlight areas of potential conflict between humans and vervets. Any locality data would be greatly appreciated.
Lots of mammals are endangered at the taxonomic levels of the species, genus, or family. But, for virtually an entire infraorder of species -- 91 of 103 recognized species in the infraorder Lemuriformes, endemic to Madagascar -- to be declared by the IUCN as either "Vulnerable", "Endangered" or "Critically Endangered" is extraordinary. The Lemuriformes represent approximately a quarter of all species in the Order Primates, so their future has implications for our capacity to achieve a comparatively-based understanding of patterns of behaviour across primate species.
I'm interested in writing a book that collects folklore about monkeys, apes, and prosimians (lemurs, lorises, and tarsiers) from all over the world. They are present in Africa, Europe (e.g. Spain), South Asia, East Asia, Southeast Asia, Central and South America, and the Caribbean. The book (or books if I gather enough material) will be split up according to countries with similar cultures like, for example, "Africa, Egypt, and the Middle East" or "China, Korea, and Japan." The end of each section will have an essay explaining each culture's particular view of primates (good or bad) and any reoccurring motifs. The end of the book (or books) will have an essay that compares all cultures for the overwhelming human consensus of primates. In addition, I will give brief backgrounds on the species involved, as well as sections on the evolution and migration of primates. There will be plenty of art, maps, charts, and photos. I'm hoping the work will serve not only as a go to source for such material, but will also preserve stories that might otherwise not be recorded. Most importantly, I hope the project will promote conservation efforts to save endangered primate species. It has been estimated that the great apes will be extinct in the wild in just a few decades if nothing more is done to save them. This would be a travesty since they are our closest living cousins in the animal kingdom.
I would like to have an internet database as a companion to the book(s). It will have oral folklore recordings, literature, art (paintings, pots, statues, textiles, etc.), and even songs. I might even have a section on scientific research, making it a more comprehensive source. All oral/written material will be presented in its original language, as well as translations in several languages to make it more accessible. I'm going to contact Jane Goodall about this over the summer to see if she would be interested in helping in some way. She could definitely help me collect material in Africa. I would love to get funding to go all over the world recording stuff.
Having read 'Journey to the West' (JTW) and the 'Ramayana,' I have a good fix on primate folklore from China and India (I’m open to additional material, though). I know JTW is quite popular in Japan, but I’m sure there are probably native stories concerning the snow macaques. I need many more stories from Southeast Asia. I’ve only seen one so far. I've already been pointed towards some Maya legends and a website full of the culture’s vases adorned with monkey patterns. I’m still interested in folklore from other cultures in that area. That goes for the Caribbean as well. I have zero stories from Africa(!), but I'm hoping to correct that.
A great part of studies about ecology and behavior of primates approach the availability of resources (fruit, new leaves, flowers, insects and etc). However, I don't observe a standarization in this process. I would like to discuss about this theme and to know what other researchers think.
