Diet of Neotropic
cormorant (Phalacrocorax brasilianus) in an estuarine environment.
Spilostethus pandurus is also recorded for first time in the Neotropic
. Diagnosis, photographs for each genera and collecting places in the National Parks are provided.
Study site: The study was conducted in one of the freshwater system of Valley of Rio Verde, San Luis Potosi, Mexico, in the border between Neartic and Neotropic
Phylogeography and phylogeny based on molecular analysis can be very useful for describing evolution patterns in fish populations, species and communities in distinct neotropic
In a few pre-2000 surveys during the waterbird breeding season, Laguna Cuyutlan was documented as holding large colonies of some waterbirds: In 1959 (Schaldach 1963), one of the islands in basin II supported nesting of "hundreds" of neotropic
cormorants (Phalacrocorax brasilianus), 100+ little blue egrets (Egretta caerulea), 100+ great egrets (Ardea alba), some snowy egrets (E.
The sampling was undertaken between 1995 and 2000, following the methodology used by the majority of vegetation ecologists in Mexico, Central America and other places in the Neotropic
(Miranda et al.
We documented the nesting of 15 species of non-Laridae waterbirds: Neotropic
Cormorant (Phalacrocorax brasilianus), Tricolored Egret (Egretta tricolor), Snowy Egret (Egretta thula), Little Blue Heron (Egretta caerulea), Great Egret (Ardea alba), Cattle Egret (Bubulcus ibis), Black-crowned Nightheron (Nycticorax nycticorax), Yellow-crowned Night-heron (Nyctanassa violacea), Green Heron (Butorides virescens), Roseate Spoonbill (Platalea ajaja), White Ibis (Eudocimus albus), Black-bellied Whistling-duck (Dendrocygna autumnalis), Clapper Rail (Rallus longirostris), Snowy Plover (Charadrius alexandrinus), and Black-necked Stilt (Himantopus mexicanus).
Several new species have been described in different taxonomic works for the Neotropic
in the last five years as Arens y Smith 1998, Labiak 2000, Lorea y Smith 1999, Mickel 2001, Mickel y Smith 2000, Moran 2000, Moran y Ollgaard 1998, Mendoza et al.
