Spatio-temporal patterns and nutrient status of macroalgae in a heavily managed region of Biscayne Bay, Florida, USA

The coastal bays of South Florida are located downstream of the Florida Everglades, where a comprehensive restoration plan will strongly impact the hydrology of the region. Submerged aquatic vegetation communities are common components of benthic habitats of Biscayne Bay, and will be directly affected by changes in water quality. This study explores community structure, spatio-temporal dynamics, and tissue nutrient content of macroalgae to detect and describe relationships with water quality. The macroalgal community responded to strong variability in salinity; three distinctive macroalgal assemblages were correlated with salinity as follows: (1) low-salinity, dominated by Chara hornemannii and a mix of filamentous algae; (2) brackish, dominated by Penicillus capitatus, Batophora oerstedii, and Acetabularia schenckii; and (3) marine, dominated by Halimeda incrassata and Anadyomene stellata. Tissue-nutrient content was variable in space and time but tissues at all sites had high nitrogen and N:P values, demonstrating high nitrogen availability and phosphorus limitation in this region. This study clearly shows that distinct macroalgal assemblages are related to specific water quality conditions, and that macroalgal assemblages can be used as community-level indicators within an adaptive management framework to evaluate performance and restoration impacts in Biscayne Bay and other regions where both freshwater and nutrient inputs are modified by water management decisions.

Color Portrait of Charles Perry

Charles Edward Perry (Chuck), 1937-1999, was the founding president of Florida International University in Miami. He grew up in Logan County, West Virginia and graduated from Bowling Green State University. He married his wife, Betty Laird in 1960. In 1969, at the age of 32, Perry was the youngest president of any university in the nation. The name of the university reflects Perry’s desire for a title that would not limit the scope of the institution and would support his vision of having close ties to Latin America. Perry and a founding corps opened FIU to 5,667 students in 1972 with only one large building housing six different schools. Perry left the office of President of FIU in 1976 when the student body had grown to 10,000 students and the university had six buildings, offered 134 different degrees and was fully accredited. Charles Perry died on August 30, 1999 at his home in Rockwall, Texas. He is buried on the FIU campus in front of the Graham Center entrance.

Overcoming The Impotency Of Marketing

In his dialogue titled - Overcoming The Impotency Of Marketing - K. Michael Haywood, Assistant Professor, School of Hotel and Food Administration, University of Guelph, originally reveals: “Many accommodation businesses have discovered that their marketing activities are becoming increasingly impotent. To overcome this evolutionary stage in the life cycle of marketing, this article outlines six principles that will re-establish marketing's vitality.” “The opinion of general managers and senior marketing, financial, and food and beverage managers is that the marketing is not producing the results it once did and is not working as it should,” Haywood advises. Haywood points to price as the primary component hospitality managers use to favor/adjust their marketability. Although this is an effective tool, the practice can also erode profitability and margin he says. Haywood also points at recession as a major factor in exposing the failures of marketing plans. He adds that the hotel manager cannot afford to let this rationale go unchallenged; managers must take measures to mitigate circumstances that they might not have any control over. Managers must attempt to maintain profitability. “In many hotels, large corporate accounts or convention business generates a significant proportion of occupancy. Often these big buyers dictate their terms to the hotels, especially the price they are prepared to pay and the service they expect,” Haywood warns. This dynamic is just another significant pitfall that challenges marketing strategy. The savvy marketing technician must be aware of changes that occur in his or her marketplace, Haywood stresses. He offers three specific, real changes, which should be responded to. “To cope with the problems and uncertainties of the hotel business during the remainder of the decade, six components need to be developed if marketing impotency is to be overcome,” says Haywood in outlining his six-step approach to the problem. Additionally, forward thinking cannot be over-emphasized. “A high market share is helpful in general, but an even more crucial factor is careful consideration of the market sectors in which the company wants to operate,” your author advises. “Taking tactical initiatives is essential. Successful hotels act; unsuccessful ones react. The less successful marketing operations tend to be a hive of frantic activity. Fire-fighting is the normal way of life in such organizations, Haywood observes. “By contrast, successful firms plan and execute their tactical marketing activity with careful timing and precision so as to create the maximum impact,” he extends in describing his fruitful marketing arabesque.

Grandparents: “The New Parents”

Over the course of the past decade, the number of grandchildren under the custody of their grandparents is steadily increasing. The majority of these grandparents lack the necessary skills to successfully attend to the academic needs of their grandchildren. The purpose of this action research is to provide viable answers for the following questions: Will grandparents feel more comfortable addressing school related issues after participating in programs geared towards their grandchildren’s academic success? Do programs geared towards their grandchildren’s academic success influence the grandparent’s level of participation in school related issues? As a result of the program, will grandchildren feel more confident seeking and receiving assistance from their grandparents?

Could Relatedness Help Explain Why Individuals Lead in Bottlenose Dolphin Groups?

In many species, particular individuals consistently lead group travel. While benefits to followers often are relatively obvious, including access to resources, benefits to leaders are often less obvious. This is especially true for species that feed on patchy mobile resources where all group members may locate prey simultaneously and food intake likely decreases with increasing group size. Leaders in highly complex habitats, however, could provide access to foraging resources for less informed relatives, thereby gaining indirect benefits by helping kin. Recently, leadership has been documented in a population of bottlenose dolphins (Tursiops truncatus) where direct benefits to leaders appear unlikely. To test whether leaders could benefit indirectly we examined relatedness between leader-follower pairs and compared these levels to pairs who associated but did not have leader-follower relationship (neither ever led the other). We found the average relatedness value for leader-follower pairs was greater than expected based on chance. The same was not found when examining non leader-follower pairs. Additionally, relatedness for leader-follower pairs was positively correlated with association index values, but no correlation was found for this measure in non leader-follower pairs. Interestingly, haplotypes were not frequently shared between leader-follower pairs (25%). Together, these results suggest that bottlenose dolphin leaders have the opportunity to gain indirect benefits by leading relatives. These findings provide a potential mechanism for the maintenance of leadership in a highly dynamic fission-fusion population with few obvious direct benefits to leaders.

The Maintenance and Consequences of a Low Quality Diet in Poecilia Latipinna

The adaptive significance of herbivory in nature is not well understood. In order to document the conditions that select for an herbivorous feeding habit, we must first understand how such a diet is maintained, and the consequences of doing so. A few studies have begun to reveal mechanisms of maintaining herbivory (i.e. selective feeding, diet mixing, etc.) and the associated life history responses (i.e. growth, reproduction, etc.) in terrestrial and marine systems; however, studies of this kind are underrepresented in the freshwater literature. In this study, I use the sailfin molly (Poecilia latipinna) as a model organism to examine diet selectivity and the effects of an herbivorous diet on growth. To study food selectivity, sailfin mollies were fed either disturbed or intact periphyton mats from one of three localities within the Everglades (Water Conservation Area 3B, the Gap, or Chekika). Mats are structured with palatable algal species (i.e. greens and diatoms) comprising the inner components of the mat, and unpalatable species (i.e. cyanobacteria) comprising the outer edges. Fish gut contents were analyzed for each treatment and periphyton locality. Results suggest that when provided access to the inner components of the mats, fish preferentially eat more palatable algae. In a second experiment, effects of an herbivorous diet were examined using neonate sailfin mollies. Fish were fed either commercial food flakes, commercial algae flakes, or ground periphyton, and growth rate was measured weekly, from birth to 21 days. Fish fed the commercial diets grew at a faster rate and reached a larger final size than those fed periphyton. These results suggest that a periphyton diet is limited in nutritional elements compared to a pure algae diet and herbivorous organisms feeding upon it may experience negative effects on growth. By studying the costs and benefits of herbivory in a freshwater system, this paper contributes to a larger study of the question of why herbivory would evolve as an adaptation when seemingly inefficient compared to carnivorous and omnivorous diets.
