Lemur - Science topic
A genus of the family Lemuridae consisting of five species: L. catta (ring-tailed lemur), L. fulvus, L. macaco (acoumba or black lemur), L. mongoz (mongoose lemur), and L. variegatus (white lemur). Most members of this genus occur in forested areas on Madagascar and the Comoro Islands.
Questions related to Lemur
I am using an ICPMS for my thesis research to study the mineral composition of lemur diets. I am testing different dilutions now (100, 1000, 5000, 10,000 and 20,000-fold) and there are always negative values in my results regardless of the dilution. Do the negative values mean the mineral is not present in the sample, the concentration of the sample is too small to detect? I have a 5 point calibration curve (1 - 0.0001).
Thanks in advance
I have recorded behavioural data, such as incidences of aggression and grooming partners, in a troop of lemurs over three conditions.
What tests should I be using to compare the rates of aggression in the three conditions?
For the grooming partner data, I want to compare grooming between sex dyads. For instance, the frequency of male-male grooming compared to male-female grooming within each condition and then compare the average proportion of grooming between sex dyads in the three conditions. How would I do this?
Thank you in advance for your help. Apologies if this question is poorly worded, I am very new to data analysis.
I'm trying to find a source of year-by-year climate data (precipitation and temperature data) over at least a 20 year time period, which I can plug into QGIS. I want to calculate inter-year variation in these climate measures, within the geographic ranges of several lemur species on Madagascar. I've already found WorldClim which gives average annual precipitation and temperature, and intra-year variation (seasonality) in the format I want, but I can't get the inter-year data I need from there... any ideas for alternative sources?
Thanks!

I have tested that the amount of categories representing threats to lemur conservation is different before and after the visit to a reserve. Is there a test that allows me to explore if this difference can be influenced by the kind of reserve, the presence of photos, foraging, tourists nationality or age?
thank you very much
I am trying to analyse personality of lemurs using emergence test (measurement of the latence to escape of box over 5 minutes).
I am facing difficulties to determine what kind of distribution this fits, since there are more data close to zero, and then individuals that never excaped at the end of the experiment. Clearly not a gaussian distribution, but when I log-transform and remove both extremities, it looks like one.
Do you advise to transform the data so that it fits a known distribution?
Thank you for your help.
I am currently researching endoparasites found in a species of lemur native to madagascar and how anthropogenic forest fragmentation may result in higher parasite loads. Does anybody know why there would be a higher load at the edge of a fragment compared to the core?
I am looking into parasite loads within a species of lemur native to Madagascar and have collected over 100 samples of feces but each sample is only around 1 g, so I need to find a method to effectively analyse the samples without losing loads of eggs. Does anybody have a method that is good for analysing small samples for parasite egg counts?
I was wondering if anyone was aware of any examples of evidence for zoonotic transmission of pathogens from lemurs to humans or vice versa?
