    Field guide recommendations for dragonflies and butterflies needed

    For butterflies I am very happy with the Collins guide from Tolman & Lewington, which seems to pack in more information than the haahtela guide. It has served me very well across Europe.

    Lynx's Checklist of Mammals of the World - my two cents

    I think we are more or less on the same line here, I don't believe in true species concepts either and would always argue for presenting multiple lines of evidence. The BSC in a way is a good species concept in the sense that if different populations cannot interbreed they for sure should be...

    Lynx's Checklist of Mammals of the World - my two cents

    That there is data in the Ungulate Taxonomy book (which I also own and have studied in detail) doesn't mean that the data in there supports all the splits, far from it... Many splits (Klipspringers are the easy example) are not supported at all by the data and it is made worse that the relevant...

    Lynx's Checklist of Mammals of the World - my two cents

    I disagree, the level for accepting splits is extremely inconsistent in the literature and as they have just copied the literature there is a gigantic inconsistency in the new checklist as to what is a species (and many bovid splits in the current checklist aren't even supported by data). That...

    Lynx's Checklist of Mammals of the World - my two cents

    There indeed hasn't been an attempt since the 2005 book and I would think this book would be a prime occasion to establish such a tradition and it would benefit the mammal watching and conservation society to have one. They even brought someone on board from the new ASM Mammal Database so the...

    Lynx's Checklist of Mammals of the World - my two cents

    Did they at least manage to get the distribution maps correct for the Bovids? In HMW they just copy pasted them from the Ungulate Taxonomy book, which meant distributions were often incomplete, very notable for Klipspringer... I probably won't buy the book, it is a shame they didn't take their...

    What's the best field guide for Ecuador?

    You are aware that most Helm Field Guide titles are published in the US by Princeton, so different publisher, but exactly the same content...

    Birds of East Africa -Field Guides

    I gave away my old copy last year to some local rangers, so I have to compare based on memory. For the most part a lot seems to have stayed the same, with relatively few new illustrations. The biggest plus is the new maps that show highlands and have been updated completely (and show multiple...

    Gentoo Penguin possible future split into 4 species

    It seems that they use a PSC approach and at least some of the methodology is flawed (multivariate analysis is only a good tool if the different input variables are independent and it is quite clear they aren't). Overall still interesting to find such genetic differences and some morphological...

    Birds of East Africa -Field Guides

    Based on the Princeton website it has 2 more plates than the first edition (289) and covers 1448 species (compared to >1300 for the first edition). The plates seem more crowded than the first edition, but that is probably necessary to get so many species in a portable book....

    HMW Handbook of the Mammals of the World

    Based on the sample pages they do take a splitty approach, but taxonomy is still looking very inconsistent regarding ungulates.

    Lynx code

    The list seems identical to the list from HMW, so highly inconsistent.

    HMW Handbook of the Mammals of the World

    I would buy that book in a heartbeat then..... I wonder whether this new checklist will use a consistent taxonomy like their bird checklists, but given the coming "regional checklists" still use inconsistent taxonomy, I don't have much hope.... What use is a checklist if for one family an...

    Bovids of the World, Castello et al

    With respect to the taxonomy, the pdf attached to this post gives a pretty good overview: https://www.zoochat.com/community/threads/ungulate-taxonomy-revisited-the-evidence-for-the-splits-of-g-g.467230/page-14#post-1180892 For more details in individual species, you have to check their...

    Bovids of the World, Castello et al

    The Canids book that came after it was much better when it comes to taxonomy, with only 1 dubious split (American vs. Eurasian Red Fox), but I don't own it, so don't know about any other errors. I am personally not a big fan of such field guides as they are impractical to take into the field...

    Bovids of the World, Castello et al

    I don't think it ever has been. But you can spare yourself the cost of buying one, it is full of errors and dubious splits. The only real way it is of value is as a graphical complement to the heavily criticized Ungulate Taxonomy book by Groves & Grubb.

    What antelopes live in Mt. Cameroon?

    Without more details it isn't possible to say whether you have seen a Bushbuck or a Bongo. It must be noted that Bongo are quite hard to see in the wild, whereas Bushbuck are much easier.

    That would very well be possible and that idea has been raised before as both donaldsoni and leucotis seem to occur parapatrically in e.g. Bale mountains. But this paper doesn't really answer that question, just puts another questionmark at the current status quo.
  19. T


    I went through this paper, but the results are not very convincing at a species level for me. There may be a good case for the recognition of the genera, but they use a narrow PSC view with very limited genetic data, so it is not really clear how valid their results really are. What is...

    Red Squirrels in Vienna

    Willd European Hamsters are particularly common around the Meidling graveyard and on the grounds of the nearby hospital. Another good place is the park next to the water tower at Windtenstrasse. European Souslik used to be found commonly found in the fields east of Oberlaa (S Vienna), but might...

    Best Mammal guide to Africa

    Fortunately new primate plates are in the works, now let's hope that they also ditch the inconsistent taxonomy, i.e. stop treating most of the G&G working hypotheses as real splits.

    Best Mammal guide to Africa

    The Kingdon Field Guide is still the best option, though I would advise you to get the new complete version, not the pocket guide. The illustrations can be off from time to time, but it treats all Mammal families. Bats, insectivores, afrotheria and rodents are mostly treated to the genus level...

    Red Panda split

    Difference is that they infer a split based on whole genomes of 3 million years ago, which combined with the present morphological differences, could indicate this species is valid. But as mentioned by others they did not sample in part of the range (Bhutan & N India), so maybe new research...

    Uganda Mangabey

    PSC offers a neat solution to a problem for which there is no neat solution. Diagnosibility is a nice criterion in theory, but in practice it means that with enough (or too little) data you can split any given populatiom of you use it strictly. Both BSC and PSC are imperfect concepts. Both have...
