The Puerto Rican parrot is a uniquely American parrot, but one of eight parrot species found in the Caribbean (30 species comprise the 4 million years (MY) old-genus radiation in the Amazon region), a graphic example of speciation via island biogeography.
Both k-medoids and HOPACH suggest similar age estimates (Table 1), with most notably a recent diversification (<5 MY) of the genus Microcebus.
Despite its relatively recent origin (approximately 10 my old), the genus Agave has a high adaptive radiation and an active process of speciation, with a diversification rate (0.32 species per my), only comparable with the rosetophyllous silversword (0.56 species per my) (Baldwin and Sanderson 1998; Eguiarte and Souza 2007).
The focus of the research in my laboratory is the genus of parasitic protozoan, Leishmania, which causes a spectrum of diseases known as leishmaniasis.
As a child, I admired my parents' original 1982 Genus Edition: I loved the plain, dusty blue box, the candy-colored triangular plastic wedges, and the crisp, unbent cards.
I was very excited to learn the sound analysis techniques from the leading researchers in the field and and eager to apply them to my questions regarding Nyctibatrachus genus as mentioned earlier.
So every time I hear about the discovery of a new species in the genus Nyctibatrachus, my mind thinks about habitat, calling pattern, breeding behavior, and evolution of these species in streams and forests of the Western Ghats.
Fast forward two months and scientific names flood my brain, as families and genus float in and out of my mind.
my] and crown [2.5 my] age of the genus Oreotrochilus, of which we included three of its six species.
This year I'm employing a new strategy picked up from my colleagues at Kew to help my collection fight back: a genus of carnivorous plants called Pinguicula, more commonly known as the butterworts.
