<font color="#3333ff">I'm not sure what you mean 'allowable', but
your table looks fine. Isopleth area is given in map units
squared, so if your map units are meters then dividing by 10^6
gives you km2 (as you've done). A reader may want to know more
what 'duplicate points' means. because two fixes at the same
location are fine as long as they have different time stamps. <br clear="none">

<br clear="none">
<font color="#3333ff">When you're working with subsets of your data
from the same individual, using the same parameter values (k and
s) is pretty standard, and certainly defensible in terms of
comparing apples to apples. This presumes that the movement
pattern and sampling intervals in the wet and dry seasons are not
dramatically different. If on the other hand, for example, there
are many more spatial outliers in the dry season (because the
animal was wondering far and yonder in search of water sources),
then the same value of k that did a nice job modeling space use in
the wet season could potentially result in large ispoleths in the
dry season that include large areas where the animal never was (in
which case you might </font><font color="#3333ff"><font color="#3333ff">to switch to the 'a' method which is generally
more robust to different geometric distributions of points)</font>.
Hence inspecting the isopleth-area curves and isopleth maps for a
reality check is still worth doing, but if they are not too
dissimilar then using the same parameter values would be a good
choice. <div class="yiv6499431295yqt5330907712" id="yiv6499431295yqtfd25574"><br clear="none">
