I'm a Tropical Ecologist and my research at University of Detroit Mercy focuses on the ecology & evolutionary biology of species interactions.

Salvador worm salamander
An amazing find; this Salvador worm salamander (Oedipina salvadorensis) is an endemic species - and was recently separated from the more widespread O. taylori. Here's a cool paper justifying the split using its distinctive ecology: Brodie et al. 2012.

Hardened lava flows of "El Playon"
The San Salvador Volcano "Quetzaltepec" produced the eruption known as "El Playon" around 1658, which destroyed the town of Nexapa (later relocated & renamed Nejapa). The picture above is an example of primary succession - the plants that colonized these hardened lava flows have to make do without any soil! These early pioneer species will eventually prepare a soil matrix that will give way to other successional communities that can't thrive on bare rock - but the process is slooow, the flow picture above is just 354 yr old. Here's a cool paper on successional "facilitation": Callaway 1995.

Variegated squirrel
There are lots of subspecies of variegated squirrels (Sciurus variegatoides) in Central America, and the color morphs vary tremendously. This little squirrel got zapped by a power line in Zaragoza (La Libertad, El Salvador) & I managed to get a quick picture while it was recovering in the crook of a Maquilishuat (Tabebuia rosea) tree. Here's a great paper on that describes the geographical distribution of variegated squirrels in El Salvador: Owen & Girón 2012.

Achiote plant
The fruit of Bixa orellana (Bixaceae), growing in the streets of Old San Juan, Puerto Rico! This is the source of Achiote - a colorant and condiment used in many popular dishes, such as yellow rice.

Mirador/ Look-out at Deininger National Park
I finally got a chance to visit Walter Thilo Deininger National Park. This is an important park (732ha),
as its the only protected area in El Salvador assigned to the
preservation of Tropical Dry Forest - which itself is a fascinating
mosaic of two habitat types: deciduous forest (which is leafless during
the dry season) & gallery forest (which retains its leaves all year
round).
This video is a 360 degree panoramic of deciduous & gallery forest, juxtaposed against a massive landscape of cultivars (including plantains & sugar cane). Also, if you look carefully, you can see the Pacific Ocean in the background!

Yellow-eared bat
I caught this amazing male yellow-eared bat (Vampyressa sp.) in my in-law's backyard! It was a pretty exciting night, this was my time mist-netting in Zaragoza (La Libertad), El Salvador. I couldn't ID the species; there are no field-keys for El Salvador - but that's also true for many other Central American countries. Here's a great paper by Hernández-Dávila et al. 2012.
