Elevational and Seasonal Patterns of Butterflies and Hawkmoths in Plant
www.nature.com/scientificreports OPEN Elevational and seasonal patterns of butterfies and hawkmoths in plant‑pollinator networks in tropical rainforests of Mount Cameroon Jan E. J. Mertens1, Lucas Brisson1,2, Štěpán Janeček1, Yannick Klomberg1, Vincent Maicher1,3,5, Szabolcs Sáfán4,6, Sylvain Delabye1,3,4, Pavel Potocký3, Ishmeal N. Kobe1, Tomasz Pyrcz7 & Robert Tropek1,3* Butterfies and moths are conspicuous fower visitors but their role in plant‑pollinator interactions has rarely been quantifed, especially in tropical rainforests. Moreover, we have virtually no knowledge of environmental factors afecting the role of lepidopterans in pollination networks. We videorecorded fower‑visiting butterfies and hawkmoths on 212 plant species (> 26,000 recorded hrs) along the complete elevational gradient of rainforests on Mount Cameroon in dry and wet seasons. Altogether, we recorded 734 fower visits by 80 butterfy and 27 hawkmoth species, representing only ~ 4% of all fower visits. Although lepidopterans visited fowers of only a third of the plant species, they appeared to be key visitors for several plants. Lepidopterans visited fowers most frequently at mid‑ elevations and dry season, mirroring their local elevational patterns of diversity. Characteristics of interaction networks showed no apparent elevational or seasonal patterns, probably because of the high specialisation of all networks. Signifcant non‑linear changes of proboscis and forewing lengths were found along elevation. A positive relationship between the lengths of proboscis of hesperiid butterfies and tube of visited fowers was detected. Diferences in foral preferences were found between sphingids and butterfies, revealing the importance of nectar production, foral size and shape for sphingids, and foral colour for butterfies. -

Trophic-Based Analyses of the Scotia Sea Ecosystem with an Examination of the Effects of Some Data Limitations and Uncertainties
Trophic-based analyses of the Scotia Sea ecosystem with an examination of the effects of some data limitations and uncertainties Sarah Collings Doctor of Philosophy University of York Biology September 2015 Abstract The Scotia Sea is a sub-region of the Southern Ocean with a unique biological operation, including high rates of primary production, high abundances of Antarctic krill, and a diverse community of land-breeding predators. Trophic interactions link all species in an ecosystem into a network known as the food web. Theoretical analyses of trophic food webs, which are parameterised using diet composition data, offer useful tools to explore food web structure and operation. However, limitations in diet data can cause uncertainty in subsequent food web analyses. Therefore, this thesis had two aims: (i) to provide ecological insight into the Scotia Sea food web using theoretical analyses; and (ii) to identify, explore and ameliorate for the effects of some data limitations on these analyses. Therefore, in Chapter 2, I collated a set of diet composition data for consumers in the Scotia Sea, and highlighted its strengths and limitations. In Chapters 3 and 4, I constructed food web analyses to draw ecological insight into the Scotia Sea food web. I indicated the robustness of these conclusions to some of the assumptions I used to construct them. Finally, in Chapter 5, I constructed a probabilistic model of a penguin encountering prey to investigate changes in trophic interactions caused by the spatial and temporal variability of their prey. I show that natural variabilities, such as the spatial aggregation of prey into swarms, can explain observed foraging outcomes for this predator. -

Generic and Subtribal Classification of American Vernonieae
SMITHSONIAN CONTRIBUTIONS TO BOTANY NUMBER 89 Generic and Subtribal Classification of American Vernonieae Harold Robinson Smithsonian Institution Press Washington, D.C. 1999 ABSTRACT Robinson, Harold. Generic and Subtribal Classification of American Vernonieae. Smithso- niun Contributions to Botany, number 89, 116 pages, 1999.-The Vernonieae in America is herein defined to exclude the Liabeae and Pseudostifftiu (Moquinieae), and to include elements sometimes placed in the Heliantheae (Trichospiru) or Lactuceae (Stokesiu). Pollen, style bases, raphids, inflorescence form, involucre, anther appendage, and chemistry are some characters used in the reclassification. Tables 1-12 indicate the distribution of these characteristics in most American genera. Vernoniu s.s., with type A pollen, is typified by K noveborucensis (L.) and occurs in the Bahamas, eastern North America, south to central Mexico and has two spe- cies in temperate South America. All other species previously placed in Vernoniu need to be removed from the genus, a process that is nearly complete for neotropical species. Most Amer- ican Vernonieae seem to form a single related subgroup in the tribe. Subtribes included in the related subgroup are the Lychnophorinae (x = 15, 17, 18) and Centratherinae (x = 16) with type A pollen and hroheliangolides; Piptocarphinae (x= 17) with type A pollen, deciduous inner involucre, and sometimes opposite leaves; Vernoniinae (x = 17), many with glanduliferous anther appendages (including the Lepiduplou complex mostly with echinolophate pollen); and the newly proposed subtribes Sipolisiinae with type A pollen, armed receptacles, and carbon- ized achenes; Chrestinae with echinolophate pollen; and Leiboldiinae (x= 19) with type A pol- len, large heads, and a modified callus at the top of the achene. -
