Comparative Studies Of Evolutionary Responses To Light Environments In Arabidopsis, Massimo Pigliucci, Heidi Pollard, Mitchell B. Cruzan

Biology Faculty Publications and Presentations

In this article, we compare the reaction norms to foliage shade (changes in light quality, spatially fine-grained environmental variation) and photoperiod (day length, spatially coarse-grained environmental variation) in several haplotypes of Arabidopsis thaliana from Scandinavia. We found that both across-environment means and phenotypic plasticities evolved continuously and very rapidly within this group. Both character means and trait plasticities were highly integrated, in part as predicted by the adaptive plasticity hypothesis for response to foliage shade (the so-called shade-avoidance syndrome). We found that a significant but small fraction of the variance in across-treatment trait means and plasticities in response to one …

Populations Of Phaeophyscia Leana (Tuck.) Essl. Within The Ohio River Basin, R. N. Gillespie

Masters Theses

Phaeophyscia leana (Tuck.) Essl., an endemic North American lichen species presently known to occur only within the Ohio River basin, is state-endangered in Illinois and a potential candidate for the Federal Endangered Species list. Since it utilizes periodically inundated corticolous substrates associated with river channels, oxbow lakes, and sloughs, this imperiled lichen is sensitive to landuse patterns within river floodplains. Surveys for P. leana were conducted to recensus previously documented populations, thereby assessing their stability, and to identify additional populations within the Ohio River Basin. Watercraft surveys were conducted on the Little Wabash River, from Carmi to New Haven, Illinois, …

Cross-Shelf Habitat Utilization Patterns Of Reef Fishes In Southwestern Puerto Rico, John D. Christensen, Christopher F.G. Jeffrey, Chris Caldow, Mark E. Monaco, Matthew S. Kendall, Richard S. Appeldoorn

Gulf and Caribbean Research

In June 2000, the National Ocean Service and University of Puerto Rico initiated a long-term reef-fish-monitoring program in La Parguera, Puerto Rico. Objectives of this ongoing work are to: 1) develop spatially-explicit estimates of reef fish habitat utilization patterns to aid in defining essential habitats, and 2) provide a quantitative and ecologically sound foundation to delineate marine reserve boundaries. Central to this effort are recently completed digital and georeferenced benthic habitat maps for the near-shore waters of Puerto Rico. The GIS-based map served as a framework for development of a spatially stratified reef-fish-monitoring program across the shelf. Simultaneous collections of …

Connectivity Between Coastal Habitats Of Two Oceanic Caribbean Islands As Inferred From Ontogenetic Shifts By Coral Reef Fishes, I. Nagelkerken, G. Van Der Velde

Gulf and Caribbean Research

Mangroves and seagrass beds are considered important nursery habitats for juveniles of coral reef fishes. Studies have mostly focused on the fish community of just one habitat, so the connectivity between different coastal habitats is often unclear. In this study, density and size of reef fish were determined using a single sampling technique in four non-estuarine bay habitats and four reef zones in Curaçao and Bonaire (Netherlands Antilles). The data indicate that of the complete reef fish community at least 21 species show ontogenetic crossshelf shifts in habitat utilization. The 21 species mainly utilized shallow-water habitats (mangroves, seagrass beds, channel …

Spawning Aggregation Sites Of Snapper And Grouper Species (Lutjanidae And Serranidae) On The Insular Shelf Of Cuba, Rodolfo Claro, Kenyon C. Lindeman

Gulf and Caribbean Research

Twenty-one spawning aggregation sites on the Cuban shelf were identified for eight species of snappers (Lutjanus) and groupers (Epinephelus and Mycteroperca) using information from experienced fishers and field studies. Three sites are on the southeastern shelf, eight on the southwest shelf bordering the Golfo de Batabanó, two in the northwest, and eight in the north-central region along the margins of the Archipiélago de Sabana-Camagüey. These numbers may reflect sampling effort as much as absolute aggregation numbers, with most effort concentrated in the southwest and north-central regions. Additional studies, particularly field assessments, are needed to determine the …

Population Biology Of The Ghost Shrimp Sergio Trilobata (Biffar 1970) (Crustacea: Decapoda: Thalassinidea), J.L. Corsetti, K.M. Strasser

Gulf and Caribbean Research

Sergio trilobata is a common burrowing crustacean found in Tampa Bay, Lemon Bay, and Miami, Florida, where it inhabits mainly intertidal soft sediments (Biffar 1971, Manning and Lemaitre 1993 ). Although S. trilobata is a dominant member of the benthic community, very little is known about population dynamics and reproduction of these thalassinideans. The population biology of this ghost shrimp was examined over a period of a year and a half to gain understanding of its life history. Seasonal variation in the proportion of individuals in each size class was observed during the study, suggesting that there may be environmental …

Feeding Selectivity Of Anchovia Clupeoides (Pisces: Engraulidae) In The Ciénaga Grande De Santa Marta, Colombian Caribbean, Guillermo Duque, Arturo Acero P

Gulf and Caribbean Research

Food selection by fishes is an important piece of information for modeling food webs in aquatic ecosystem. Monthly collections were made over a twenty-four hour period between October 1995 and June 1996 to examine the feeding selectivity of the zabaleta anchovy (Anchovia clupeoides) in the coastal lagoon Ciénaga Grande de Santa Marta, NE Colombia. A total of 4,389 specimens were collected, and the abundances and weights of the stomach food items were compared with similar measures calculated from samples obtained in nearby habitats. Our results indicate that the zabaleta anchovy is planktophagous, actively selecting copepods and detritus throughout …

Gulf and Caribbean Research

The diet of tripletail, Lobotes surinamensis, collected from the Mississippi Sound and Mississippi's offshore waters of the Gulf of Mexico between April and September 1995-1997, was investigated through analysis of stomach contents. Of 178 tripletail stomachs examined, 136 (76%) contained prey items, and 42 (24%) were empty. Tripletail with prey in their stomachs ranged from 183 to 787 mm total length (mean 522.6 mm) and 0.14 to 10.5 kg total weight (mean 3.64 kg). The diet consisted of 32 different prey types and was comprised of shrimp, crabs, and teleost fishes which were represented by about equal number and …

The Biology Of Wahoo (Acanthocybium Solandri) In The Western Central Atlantic, Hazel A. Oxenford, Peter A. Murray, Brian E. Luckhurst

Gulf and Caribbean Research

This contribution summarizes aspects of the biology of the wahoo, Acanthocybium solandri (Scombridae), that are pertinent to assessment and management of this species in the western central Atlantic (WCA). In this region wahoo is a target species for both commercial and recreational fisheries, and annual landings appear to have increased steadily over the last 30 years to in excess of 2000 mt. Wahoo is believed to be migratory, but little is known of the migration patterns. Significant seasonal variation in catches within the region indicates that it is seasonally abundant in most locations. Periods of peak abundance occur from the …

Historical Perspectives (Apoptosis), James Curtin, Thomas Cotter

Articles

Apoptosis is one of the most widely studied fields in biology and accounts for over 2% of all life science publications annually. It plays a fundamental role in development, and defects in the regulation of apoptosis are directly implicated in numerous well-known diseases including cancer, neurodegenerative disorders, tissue atrophy and auto-immune diseases. However, the field of apoptosis has humble beginnings and was neglected by biologists for much of its history. This chapter reviews the history of research in apoptosis and highlights key experiments that have contributed significantly to our current understanding of apoptosis. In addition, the topics covered in later …

Perfecting The Match: The Visual Economy Of Egg Donation, Katherine M. Boulay

Doctoral

This thesis is a response to the absence of discussion in feminist and cultural studies of Assisted Reproductive Technology’s (ART) increasing utilisation of visuality and technology as complementary legitimating discourses. While critiques of the epistemologies and practices undergirding ART point to the fact that imaging technologies are used to reveal knowledge held in bodies, lacking in current theoretical work on ART, however, is an ethnographic engagement with how visual technologies actually produce the internal and externalscapes of these bodies, and knowledges about them. Mapping selective visual knowledges and technologies constitutive of the ART egg donation, the thesis engages with disparate …
