ECOLOGÍA TRÓFICA DEL PIQUERO DE NAZCA Sula granti (AVES: SULIDAE) EN LA ISLA MALPELO, COLOMBIA
Authors: García Silvana , López Victoria Mateo
Published: October 2017

The trophic ecology of Nazca Booby was evaluated through the analysis of gut contents collected between September 2004 and July 2005 during five field trips. From 110 induced regurgitation samples, the diet was analyzed using the variables number, weight and frequency of occurrence of the different nutritious categories, and using the distribution of the frequencies of sizes of preys at general, intraspecific and temporal levels. Oxyporrhamphus micropterus (halfbeaks fishes, family Hemiramphidae) and fishes of the family Exocoetidae (flying fishes) were the principal components found on the diet, followed by fishes of the families Carangidae and Escombridae. Variations were present in the consumption of the distinct categories at general, intraspecific and temporal levels, with the strongest differences in the consumption of preys of the family Hemiramphidae. The quantity of food taken by S. granti at Malpelo Island showed close relation with its reproductive cycle, and it adjusted to the model of energetic demand proposed for marine birds. Comparisons with other analogue studies showed slight differences between localities, apparently related with the availability of preys. It seems like there is a niche partition between females and males of S. granti at Malpelo Island related with the quantity and sizes of the preys ingested, and in a lesser degree with the composition of the diet. The present work is the first one to evaluate in detail the diet of the Nazca Booby and considerably extends the geographical range of this kind of studies in the Eastern Pacific.
EFECTOS DE LARGO PLAZO DE INSTRUMENTOS DE REGULACIÓN PESQUERA: CASO DE LA PESQUERÍA DEL JUREL TRACHURUS MURPHYI (NICHOLS, 1920) EN LA ZONA CENTRO SUR DE CHILE
Authors: Tíjaro Rojas Rocío , Salgado Cabrera Hugo
Published: October 2017

Chilean Pacific jack mackerel (Nichols, 1920) fishery yields about 90% of the Eastern South Pacific catch. The Southern Central region is the one that concentrates the major abundance of this resource. The objective of this study is to test which of the regulation fishery systems is the most efficient for this fishery from a bioeconomic approach. Based on catch and effort data, the behaviour of the T. murphy stock and the fishing fleet was simulated over time under three regulatory scenarios: open access, total allowable catch and individual transferable quotas. The behaviour of the fish stock, and the dynamics of fishing vessels coming in and going out over time from the fishery, were represented by equations of the model. The results indicate that when the fishery operates in open access, the biomass and economics benefit diminished, whereas the number of fishing vessels increased (mostly small and middle-sized ones). Upon imposing the total allowable catch, biomass increased and maintained over time, while the size fleet decreased (middle-sized and large vessels). Within the individual transferable quotas view, the fish stock behaves in a similar way to the total allowable catch measure. However, significant differences in terms of fleet size (reduction of only 10% of the initial size), as well as structure (remaining only large vessels in operation) and economic profits obtained (maximum in this regulation), arise from this framework modelling. In conclusion, from the fishery bioecomic point of view the individual transferable quotas was the best management scenario for the Southern Pacific Jack Mackerel.

Authors: Vega Sequeda Johanna , Rodríguez Ramírez Alberto , Reyes Nivia María Catalina , Navas Camacho Raúl
Published: October 2017

Twenty coral formations were evaluated in the area of Santa Marta in terms of: 1) composition and abundance of the principal substrate categories and 2) prevalence of coral diseases and bleaching. To obtain the information, bands of 10 x 1 m and 10 x 2 m were used, respectively. A total of 33 species of hard corals were registered. Algae and corals were the components with major cover, nonetheless, averages varied widely in the study area (coral= 4.0 ± 0.9 %-62.0 ± 7.2 %; algae = 30.6 ± 11.0 %-78.3 ± 3.0 %). The coral species with the highest averages cover were Colpophyllia natans, Diploria strigosa, Acropora palmata, and Montastraea cavernosa (7.5 ± 2.7 %, 6.7 ± 2.1 %, 4.0 ± 2.8 %, and 3.8 ± 1.0 %, respectively). Prevalence of coral diseases and bleaching were lower than 4 %. The reefs with the highest coral covers were associated to the Parque Nacional Natural Tayrona (Gayraca, Aguja, Chengue and Neguanje), whereas the lowest values were found near the urban centers (Santa Marta and El Rodadero). Even though there are some coral reefs showing relatively good conditions in the area of Santa Marta, the widespread trend is that algae are the predominant component of reef substratum.

Authors: Sierra Rozo Omar , Mancera Pineda José Ernesto , Santos Martínez Adriana
Published: October 2017

Litter degradation was studied in various substrates of three mangrove wetlands in San Andrés Island, Colombian Caribbean, during the rainy season. Decomposition rates of Rhizophora mangle L. (red mangrove), Laguncularia racemosa (L.) C.F. Gaertn. (white mangrove) and Avicennia germinans (L.) L. (black mangrove) were measured in mesh bags. Some bags were placed below ground, other submerged in water, and other on the ground. Two sites in the study were fringe wetlands and the other one was an inland wetland. Some physical-chemical factors inuencing the decomposition of vegetal organic matter were evaluated. The best regression model tted to the degradation trends was the single square root. The interactions of time with biotic and abiotic factors determined the loss of weight from leaves. The faster degradation rates were obtained in fringe wetlands; aquatic and moisten edaphic environments; on A. germinans; and at the sites with associated consumer macrofauna. The fastest velocities were presented In the early stages of decomposition. In general, the smaller average percentage of remaining biomass after 15 weeks of incubation was presented by A. germinans (10 %), respect to R. mangle (29 %) and L. racemosa (28 %). By means of the results obtained and those one related with the rates of litter production in the same wetlands in study, a basic conceptualquantitative model of litter production-decomposition dynamic in San Andrés Island is proposed.
INFLUENCIA DE LA DENSIDAD LARVAL INICIAL DE SIEMBRA Y LA CONCENTRACIÓN DE ALIMENTO SOBRE LA LARVICULTURA DE ARGOPECTEN NUCLEUS (OSTREOIDA: PECTINIIDAE)
Authors: Acosta Ortiz Ernesto , Gómez León Javier
Published: October 2017

Argopecten nucleus is a scallop bivalve native from the Colombian Caribbean, with great potential culture, but the critic point for a large-scale production is the scarce seed spat available in the environment. For this reason, its production in the laboratory is the most promising source. There is no consensus about feeding with respect to the larval sowing density after several studies, since generally each factor is worked separately. Therefore, in this research we studied the joint effect of the larval initial density and the feed ration, testing three different densities, 5, 10, and 15 larvae mL-1 and three feed concentrations, 20000, 40000, and 70000 cells mL-1 of Isochrysis galbana, over the surviving, growth, condition state (full, halffull, and empty larvae), deformity or malformation, and development of the eye spot. There was not interaction between factors with regard to surviving, growth, and deformity, but over condition state. There were not significant differences with regard to survival with any of combinations tested, whereas larval density make a greatly influence in the growth and condition state, being higher in the 10 and 15 larvae mL-1 culture for the first variable and in the 10 larvae mL-1 culture for the second one. There was no significant influence by feed concentration in any case. Even so, the percentages obtained with the combination of 10 larvae mL-1 and 20000 cells mL-1 of food (L10-20C) was higher in most cases. There were not eye spot larvae in this experiment.

Authors: Cogua Pilar , Reyes María F. , Duque Guillermo
Published: October 2017

Cartagena Bay is a highly productive habitat which supports important aquatic communities and is considered an estuarine environment. During the sampling season, fie commercial fih were captured: ladyfih (Elops smithi), machuelo (Opisthonema oglinum), mullet (Mugil incilis), sea bass (Centropomus ensiferus), and corvina (Cynoscion jamaicensis), all which stomach contents were analyzed. From all the fih captured, 82.6% presented contents in their stomachs, which were separated into 57 items, such as benthic microalgae, dinoflgellates, cyanophytes, sponges, mollusks, annelids, crustaceans, and fih. According to the Importance Relative Index (IRI), E. smithi, C. ensiferus, and C. jamaicensis were classifid as third order consumers, O. oglinum as a second-order consumer, and M. incilis as fist order consumer. The most contrasting result compared to other studies, is the found for O. oglinum, suggesting that this species is not only a fiter feeding, but also a scale eater (lepidophagy).
NOTES ON THE ECOLOGY OF THE COLOMBIAN LEAFTOED GECKO (PHYLLODACTYLUS TRANSVERSALIS), ENDEMIC TO MALPELO ISLAND
Authors: López Victoria Mateo , Jurczyk Matthias , Wolters Volkmar
Published: October 2017

The Colombian leaf-toed gecko (Phyllodactylus transversalis) is the least known reptile species of Malpelo Island (Eastern Tropical Pacific). In the 37 years since its original description, no single study strictly dedicated to this species has been conducted. With the goal of providing information on the ecology and population size of this gecko, data collected during two visits to the island are presented. Behavior and reproduction were studied by following individuals during the night and by searching for hidden individuals and eggs during the day. Population’s density and habitat preferences were estimated by classifying the island’s surfaces into four types and counting geckos inside those habitats within band transects. General morphological measurements of geckos were performed as reference points for future comparisons. Phyllodactylus transversalis lays its eggs in narrow crevices of rocks, apparently communally. Reproduction seems to take place during most of the year, probably associated with the peak breeding season of seabirds. Although conspecifics shared shelters during the day, densities during the night suggest no apparent habitat preference for foraging. Population size of this species was estimated at approximately 114000 individuals.

ESTADO ACTUAL DE LA POBLACIÓN ADULTA DEL CANGREJO SEMITERRESTRE CARDISOMA GUANHUMI (LATREILLE) EN LA ISLA DE SAN ANDRÉS, CARIBE COLOMBIANO
Authors: Hernández Maldonado Annelis , Campos Campos Néstor Hernando
Published: October 2017

San Andrés, the largest island in the Colombian Caribbean, Archipelago of San Andrés, Providence and Santa Catalina, include characteristic tropical coastal ecosystems, which provide habitat for the semiterrestrial crab Cardisoma guanhumi. Between March and April 2012 a study was conducted aiming to make a preliminary evaluation of the crab population on the island. 101 adults crabs were collected manually and their main morphometric measurements were taken (carapace length and width and weight), as well as sex information. Males were more numerous (male: female sex ratio 3:1) and grew larger in terms of body weight and carapace. The species does not have any signifiant predators on the island and they are not considered by the islanders an economically important resource in this area; this may allow crabs to reach larger sizes compared to other localities along their geographical distribution. This is why the island of San Andres should be considered as a natural refuge for the species, since in other Colombian regions it is considered a vulnerable species.
EVALUACIÓN DE LA FRECUENCIA DE MUESTREO DEL PROGRAMA DE MONITOREO DE FLORA MARINA EN LA CENTRAL NUCLEAR ALMIRANTE ÁLVARO ALBERTO, RIO DE JANEIRO, BRASIL
Authors: Garcia Araujo João Pedro , Hiroyuki Kubota Alexandre
Published: October 2017

Almirante Álvaro Alberto Nuclear Complex (CNAAA) uses seawater in the cooling system of its nuclear power plants. This water returns to the environment with a 2 °C to 8 °C temperature increase. To understand the effects of this thermal effluent, there is a large environmental monitoring program that analyses physicochemical and biological parameters, including a survey of brown algae at sampling site 32B, the nearest to the thermal discharge. This work compares monthly and seasonal variations of the specific composition of brown algae to evaluate the feasibility of changing the sampling frequency of the CNAAA monitoring program. The evaluation is performed by following two approaches: a species accumulation curve and comparisons between species richness values obtained from monthly and seasonal sampling. Species accumulation curve structure indicates that brown algae diversity at site 32B is well covered. Species richness measurements indicate that there are no significant differences between monthly and seasonal samples. These results suggest that it is possible to reduce brown algae sampling frequency for the CNAAA monitoring program without significant data loss. Furthermore, it would allow the company to cut costs, thus improving the distribution of resources within its environmental monitoring program.
Dialectics of the Swing (Voter)
Authors: Pendakis Andrew James
Published: September 2017

This paper aspires to offer a brief genealogy of a new figure of political discourse and imagination I call the "radical centre". In opposition to earlier centrisms, discourses which emphasized moderation, harmony, and balance, this new configuration imbues the centre with a kind of revolutionary or radical potential linked to its capacity to avoid being "trapped" by the traditional political poles. Though this thought envisions itself as beyond ideology and in some sense beyond repetition of any kind the tropology of the centre is filled with repeating motifs and figures susceptible to analysis and critique. The claim of this paper is that the radical centre has become the dominant political rhetoric of our time and that its hegemony works to preempt the possibility of genuinely new (and inventive) forms of political imagination.

Published: September 2017

AbstrakIptek bagi masyarakat (IbM) ini dilatarbelakangi oleh kondisi masyarakat Jawa di era modern khususnya generasi muda yang tidak menguasai bahasa Jawa. Bahasa Jawa dengan tataran unggah-unguhnya menjadi alasan untuk tidak digunakan karena dianggap sulit. Kenyataan seperti ini disebabkan adanya keberbatasan pemahaman tentang hakikat bahasa Jawa yang merupakan bagian integral kebudayaan bangsa Indonesia. Bahasa Jawa tumbuh sebagai identitas diri dengan tetap mempertahankan nilai-nilai luhur yang terkandung di dalamnya. Untuk itu, kalau tidak segera dilakukan suatu upaya pembenahan dan pembinaan dalam penerapan unggah-ungguh bahasa Jawa di lingkungan masyarakat khususnya terhadap ibu-ibu rumah tangga sebagai pewaris budaya kepada generasinya, dikhawatirkan bahasa Jawa berkembang tidak sesuai dengan tatanannya. Yang lebih memprihatinkan lagi, bahasa Jawa sebagai wujud budaya masyarakat Jawa akan musnah. Oleh karena itu, sebagai wujud kepedulian dalam upaya pelestarian budaya dan pembangunan karakter terhadap generasi bangsa maka pemberdayaan terhadap ibu-ibu rumah tangga dalam peran sertanya membelajarkan penerapan unggah-ungguh bahasa Jawa di lingkungan keluarga perlu sekali dilakukan. Iptek bagi masyarakat (IbM) ini dilaksanakan dengan tujuan memberdayakan ibu rumah tangga dalam pembelajaran ungguh-ungguh bahasa Jawa di lingkungan keluarga. Sasaran dalam kegiatan ini adalah ibu-ibu tim penggerak PKK di kecamatan Tembalang. Metode yang digunakan dalam kegiatan ini adalah ceramah, tanya jawab dan simulasi yang diawali dengan tes awal dan diakhiri dengan tes akhir. Dengan materi dan buku panduan praktis penerapan unggah-ungguh bahasa Jawa yang telah disampaikan, diharapkan ibu-ibu tim penggerak PKK mendapatkan tambahan pengetahuan akan pentingnya pembelajaran unggah-ungguh bahasa Jawa dalam upaya pembentukan karakter anak, tumbuh kesadarannya dalam rangka mempertahankan dan melestarikan budaya Jawa.Kata Kunci: Pendidikan karakter, unggah-ungguh bahasa Jawa, ibu rumah tangga
