Experimental assemblage of novel plant-herbivore interactions: ecological host shifts after 40 million years of isolation.

Biotropica 2017 Nov 4;49(6):803-810. Epub 2017 Jul 4.

Department of Entomology, National Museum of Natural History, Smithsonian Institution, 20560. Washington D.C. USA.

Geographic isolation is the first step in insect herbivore diet specialization. Such specialization is postulated to increase insect fitness, but may simultaneously reduce insect ability to colonize novel hosts. During the Paleocene-Eocene, plants from the order Zingiberales became isolated either in the Paleotropics or in the Neotropics. Read More

Spatio-temporal Genetic Structure of a Tropical Bee Species Suggests High Dispersal Over a Fragmented Landscape.

Biotropica 2014 Mar;46(2):202-209

Department of Environmental Studies, Emory University, Atlanta GA 30322, U.S.A.

Habitat destruction threatens biodiversity by reducing the amount of available resources and connectivity among geographic areas. For organisms living in fragmented habitats, population persistence may depend on dispersal, which maintains gene flow among fragments and can prevent inbreeding within them. It is centrally important to understand patterns of dispersal for bees living in fragmented areas given the importance of pollination systems and recently documented declines in bee populations.

Heterospecific Acoustic Interference: Effects on Calling in Oophaga pumilio.

Biotropica 2009 Jan;41(1):74-80

Department of Ecology and Evolutionary Biology, University of California, Los Angeles, California 90095, U.S.A.

Call rate suppression is a common short-term solution for avoiding acoustic interference in animals. It has been widely documented between and within frog species, but the effects of non-anuran calling on frog vocalizations is less well known. Heterospecific acoustic interference on the calling of Oophaga pumilio (Bauer, 1994) (formerly Dendrobates pumilio) males was studied in a lowland, wet tropical forest in SE Nicaragua. Read More

Fruit Characteristics of Species Dispersed by the Black Lemur () in the Lokobe Forest, Madagascar.

Biotropica 2001 Sep 15;33(3):478-486. Epub 2006 Mar 15.

Missouri Botanical Garden, Madagascar Research and Conservation Program, BP 3391, Antananarivo, Madagascar.

Abstract: I describe the fruit characteristics of species closely associated with black lemur seed dispersal (, species that are often dispersed by die black lemur and only dispersed by the black lemur in die Lokobe Forest). A black lemur group was habituated and observed during the day and night for all months of die year (total 1272 h). When fruits were eaten, die plant species was identified, die maturity of the fruit and treatment of the seeds noted, and the fruit described in terms of ripe fruit color, husk thickness, fruit length, and seed length and width.
