Global Conservation Status of Turtles and Tortoises (Order Testudines)
TLDR
The order Testudines is, on average, more imperiled than all other larger orders (≥ 20 species) of Reptilia, Amphibia, Mammalia, or Aves, but has percentages of CR+EN and Threatened species and an ATL similar to those of Primates and Caudata (salamanders).
A revision of African helmeted terrapins (Testudines: Pelomedusidae: Pelomedusa), with descriptions of six new species.
TLDR
Using nearly range-wide sampling, mitochondrial DNA is analyzed and a minimum of 12 deeply divergent species-level clades are identified and six new Pelomedusa species are described, some of which can only be identified by molecular markers and are therefore morphologically cryptic taxa.
Mitochondrial phylogeography and subspecies of the wide‐ranging sub‐Saharan leopard tortoise Stigmochelys pardalis (Testudines: Testudinidae) – a case study for the pitfalls of pseudogenes and
TLDR
It is concluded that there is no rationale for recognizing subspecies within S. pardalis, and the distribution of mitochondrial clades does match neither the traditional subspecies ranges nor the pronounced geographical size variation of leopard tortoises.
Shaping up to fight: sexual selection influences body shape and size in the fighting tortoise (Chersina angulata)
TLDR
It was concluded that posterior carapace width is a more important variable than gular length in determining male fighting success, and it is suggested that, in addition to righting ability, posterior carAPace width may well be a trait under sexual selection in male angulate tortoises.
