Changes In The Vertical Stratification Of Neotropical Nymphalidae At Forest Edges In Relation To Light And Temperature Conditions, Brian Koji Oye
Changes In The Vertical Stratification Of Neotropical Nymphalidae At Forest Edges In Relation To Light And Temperature Conditions, Brian Koji Oye
University of the Pacific Theses and Dissertations
The composition of neotropical fruit-feeding nymphalid butterflies assemblages often varies by location and stratum within a forest. Recent work has shown that vertical stratification in particular may serve as barrier to gene flow, indicating the potential role vertical stratification may play in evolution. At forest edges, the distinction between assemblages has been described to decrease, with species considered to be canopy specialists descending to the forest understory. The similarity in light conditions between the canopy and understory strata at edges or disturbed habitat is hypothesized to be responsible for this phenomenon. We conducted a study using standardized sampling to document …
Unknown And Cryptic Diversity In The Adelpha Serpa-Group, Cassidi Rush
Unknown And Cryptic Diversity In The Adelpha Serpa-Group, Cassidi Rush
University of the Pacific Theses and Dissertations
The tropics are host to incredible insect diversity. One of the most charismatic groups that exhibit this diversity are the butterflies. Despite the tropical butterfly fauna being heavily researched, there remains much hidden diversity in the form of undescribed life histories and cryptic species. This is especially true among the species rich Nymphalidae, the brush-footed butterflies. Species in the genus Adelpha are known to be “the most trying taxonomically of all nymphalids” DeVries (1987), and as such are fruitful ground for uncovering unknown diversity. About half of the species within Adelpha have undescribed life histories, while A. serpa stands out …
