Article
The complex forces that shape butterfly wings have long been a subject of experimental and comparative research. Butterflies use their wings for flight, camouflage, mate recognition, warning and mimicry. However, general patterns and correlations among wing shape and size evolution are still poorly understood. We collected geometric morphometric me...

The aim was to determine processes driving the latitudinal diversity gradient (LDG) in New World swallowtail butterfly diversity. We tested three mechanisms commonly invoked to explain the LDG: ecological opportunity, evolutionary rates and biogeographical history. New World and Eurasia. Oligocene–Present. New World swallowtail butterfly clade (Pap...

The literature on community-based environmental management is very extensive and the discussion of the pros and cons is continuing. Presented here is an example of a successful interaction between university-based entomologists and a local rural community, detailing the change in the attitude of the town of Millbank, Jamaica, from a Giant Swallowta...
Article
Numerous hypotheses on the evolution of Neotropical biodiversity have stimulated research to provide a better understanding of diversity dynamics and distribution patterns of the region. However, few studies integrate molecular and morphological data with complete sampling of a Neotropical group, and so there has been little synthesis of the multip...
Conference Paper
The demand for alternatives to the conventional practices of pest management has increased in recent times. There is a need for control measures that are targeted, effective, and nontoxic, or of reduced toxicity to humans, mammals, birds, other non-target organisms, and the environment. Lepidopteran pests are the most damaging insects in agricultur...

Urbanus simplicius (Stoll, 1790) is a frequently encountered Neotropical skipper butterfly, ranging from northern Argentina through South and Central America to southern Texas, USA (Evans 1952; Rickard 1977), where it appears to be a non-established stray from Mexico (Neck 1996; a single record also exists for California, see Tilden 1976). Its dist...

ABSTRACT The Southeast Asian citrus-feeding butterfly Princeps (Papilio) demoleus (L.) was recently introduced into the Americas, causing an imminent threat to citrus production and ornamental flora. The human nutrient amino acid methionine has been shown by us to disrupt aminoacid-modulated ion transport systems in caterpillars and other insect la...

This study documents impacts of the small Indian mongoose (Herpestes auropunctatus) on a threatened endemic fauna occurring in a biodiversity hotspot within a hotspot, the Hellshire Hills, Jamaica. We analyzed the stomach contents of 217 mongooses and supplemented this information with behavioural observations. The mongoose’s diet consists primaril...

Morphological taxonomic techniques were used in the review of the genus Cyllopoda, leading to: four new synonymies, Cyllopoda versicolor of Cyllopoda breviplaga, Cyllopoda claudicula catabathmus of Bombyx claudicula, Cyllopoda ovata and Cyllopoda protmeta eurychoma of Phalaena osiris; resurrection to species level of Phalaena osiris; use of new com...
Chapter
This chapter focuses on the Jamaican iguana (Cyclura collei) headstart-release program. It describes the four-year survival of zoo-reared, reintroduced iguanas, and provides evidence that headstarted iguanas quickly acclimate to life in the wild and are successfully reproducing. It also suggests that headstarting is a viable conservation strategy f...
