Autores: Ebert,Luis Augusto; Branco,Joaquim Olinto.
A gaivota Larus dominicanus (Lichtenstein, 1823) é uma das aves marinhas costeiras mais comuns do litoral brasileiro, sendo capaz de utilizar vários hábitats e explorar diferentes fontes alimentares. O estuário do Saco da Fazenda é uma importante área de forrageamento e descanso para a espécie. O objetivo deste trabalho foi o de avaliar a estrutura populacional de L. dominicanus no estuário. Durante o período de fevereiro/2004 a janeiro/2005, as gaivotas foram monitoradas mensalmente, com intervalos de duas horas entre os censos, das 6 h às 20 h. As oscilações observadas na população ao longo do ano foram significativas, sendo as maiores contagens registradas em março (181,6 ± 35,1) e as menores em outubro (21,0 ± 4,9). A ocupação do estuário foi gradativa...

Interação entre fator de condição e índice gonadossomático como indicadores do período de desova em Callinectes danae Smith (Crustacea, Portunidae) da lagoa da conceição, Florianópolis, Santa Catarina, Brasil
Provedor de dados: Zoologia
Autores: Branco,Joaquim Olinto; Lunardon,Maria José; Avila,Marcelo Gentil; Miguez,Carlos Fernando.
The C. danae females were collected monthly, within the period of April/91 to March/92. The monthly average variation of the condition factor (Ø1), is associated, among other causes, to both the weight of the gonads (Ø3) and the stomach (Ø2). The difference between Ø1 and Ø3 (ΔØ) estimates the "gonadal condition" showing highest values on the reproductive cycle (May, November, January and March). These months coincide with the highest values of the gonadossomatic index. So can be used as an indicative of the period of spawning of Callinectes danae in Lagoa da Conceição, Santa Catarina, Brazil.

Provedor de dados: Biota Neotropica
Autores: Fracasso,Hélio Augusto Alves; Branco,Joaquim Olinto; Barbieri,Edison.
Cabot's Terns Thalasseus acuflavidus (Latham, 1737) are widely distributed along the Atlantic coast of South America from the Caribbean Islands (12º S) to the region of Porto Deseado, Argentina (46º S). Daily observations were conducted on the Cardos Island during 2003, 2005 and 2006 to determine timing and nesting success, and the reproductive biology of the Cabot's Terns nesting there. The first adults arrived at the colony from 22 April to 15 May during the three years recorded; a total of 144 nests were recorded in 2003, 174 in 2005 and 50 in 2006. Observed incubation time was 24.1 ± 0.35 days, and mean egg size was 5.15 ± 0.02 cm in length and 34.30 ± 0.25 g in weight. Hatching success was lowest in 2003 and highest in 2006, with natural causes (such...

Bycatch fauna of seabob shrimp trawl fisheries from Santa Catarina State, southern Brazil
Provedor de dados: Biota Neotropica
Autores: Branco,Joaquim Olinto; Freitas Júnior,Felipe; Christoffersen,Martin Lindsey.
Marine communities in tropical regions contain a great diversity of species that play key roles in ecological processes. The observed bycatch fauna in artisanal fishing for the seabob shrimp Xiphopenaeus kroyeri (Heller, 1862) in the southwest Atlantic exceeds the quantity of commercial shrimp captured. This bycatch has not been previously inventoried extensively in Brazil, particularly in the State of Santa Catarina, where small-scale shrimp fisheries is a traditional activity and dominates the local fishing economy. Six municipalities were sampled three times a month, from 1996 to 2011, yielding 216 species belonging to the bycatch (7 cnidarians, 22 mollusks, 42 crustaceans, 11 echinoderms, and 134 fishes). Bycatch management is a pressing aspect of...

A comparison of foraging between the South American and Cabot's Tern in southern Brazil
Provedor de dados: Biota Neotropica
Autores: Fracasso,Hélio Augusto Alves; Branco,Joaquim Olinto; Barbieri,Edison.
Despite being widely distributed in South America and having relatively large populations, little is known about the trophic ecology of the South American Tern (Sterna hirundinacea) and Cabot's Tern (Thalasseus acuflavidus). In Brazil, South American and Terns Cabot's breed in mixed colonies from the state of Espírito Santo to Santa Catarina. Here, we describe results of a study of the feeding ecology of these two species during the reproductive seasons of April to October of 2003, 2005 and 2006 from Cardos Island, Santa Catarina, Brazil. A total of 6248, 5140, and 4006 fishes were delivered to chicks or females by South American Terns; and 1157, 628 and 98 fish and or other prey items by Cabot's Terns during the breeding seasons of 2003, 2005, and 2006,...

Xiphopenaeus kroyeri is the most exploited shrimp specie along Center-South coast of Santa Catarina State, Brazil, by artisanal fishery. In the period from March/1996 to February/1997, 3965 shrimps were collected (1843 males and 2122 females) sampled by over-trawl, with the depth oscillating between 5 and 15 meters. Xiphopenaeus kroyeri shows seasonal fluctuations in its abundance with higher rates in autumn. The population's average total-length varied between 7.5cm and 9.1cm, and the presence of juveniles was common along the year. The males and females get to the first gonadal maturation with 7.4 cm and 9.0 cm length, respectively; these lengths were reached within 6 and 8 months of age.

Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Branco,Joaquim Olinto; Braun,Jan Raphael Reuter; Verani,José Roberto.
Mariculture has emerged as a complementary income for small fishermen along the coast of the state of Santa Catarina, Brazil, causing significant alterations in the coastal landscape and creating a new substratum seabirds. From March 1998 to February 1999, 48 censuses were carried out at four sample times, registering an average annual occurrence of 4448.7 birds, distributed among five seabird species. Laridae dominated in diversity and abundance, contributing with 98.1% of the birds recorded. The number of birds per float varied depending on the time of day and season of the year, showing an average of 2.09/1. Seabirds use the mariculture area as a place to rest, to clean their feathers and to overnight.
