  • Shrimp Fishing in Mexico
    235 Shrimp fishing in Mexico Based on the work of D. Aguilar and J. Grande-Vidal AN OVERVIEW Mexico has coastlines of 8 475 km along the Pacific and 3 294 km along the Atlantic Oceans. Shrimp fishing in Mexico takes place in the Pacific, Gulf of Mexico and Caribbean, both by artisanal and industrial fleets. A large number of small fishing vessels use many types of gear to catch shrimp. The larger offshore shrimp vessels, numbering about 2 212, trawl using either two nets (Pacific side) or four nets (Atlantic). In 2003, shrimp production in Mexico of 123 905 tonnes came from three sources: 21.26 percent from artisanal fisheries, 28.41 percent from industrial fisheries and 50.33 percent from aquaculture activities. Shrimp is the most important fishery commodity produced in Mexico in terms of value, exports and employment. Catches of Mexican Pacific shrimp appear to have reached their maximum. There is general recognition that overcapacity is a problem in the various shrimp fleets. DEVELOPMENT AND STRUCTURE Although trawling for shrimp started in the late 1920s, shrimp has been captured in inshore areas since pre-Columbian times. Magallón-Barajas (1987) describes the lagoon shrimp fishery, developed in the pre-Hispanic era by natives of the southeastern Gulf of California, which used barriers built with mangrove sticks across the channels and mouths of estuaries and lagoons. The National Fisheries Institute (INP, 2000) and Magallón-Barajas (1987) reviewed the history of shrimp fishing on the Pacific coast of Mexico. It began in 1921 at Guaymas with two United States boats.

  • Antbird Guilds in the Lowland Caribbean Rainforest of Southeast Nicaragua1
    The Condor 102:7X4-794 0 The Cooper Ornithological Society 2000 ANTBIRD GUILDS IN THE LOWLAND CARIBBEAN RAINFOREST OF SOUTHEAST NICARAGUA1 MARTIN L. CODY Department of OrganismicBiology, Ecology and Evolution, Universityof California, Los Angeles, CA 90095-1606, e-mail: [email protected] Abstract. Some 20 speciesof antbirdsoccur in lowland Caribbeanrainforest in southeast Nicaragua where they form five distinct guilds on the basis of habitat preferences,foraging ecology, and foraging behavior. Three guilds are habitat-based,in Edge, Forest, and Gaps within forest; two are behaviorally distinct, with species of army ant followers and those foraging within mixed-species flocks. The guilds each contain 3-6 antbird species. Within guilds, species are segregatedby body size differences between member species, and in several guilds are evenly spaced on a logarithmic scale of body mass. Among guilds, the factors by which adjacent body sizes differ vary between 1.25 and 1.75. Body size differ- ences may be related to differences in preferred prey sizes, but are influenced also by the density of the vegetation in which each speciescustomarily forages. Resumen.

The identification of predators of birds’ nests, crucial to a better understanding of predator-prey interac- tions, remains poorly known. Here we provide evidence that birds, and especially passerines, may depredate birds’ nests in the Cerrado (Neotropical Savannah) of Central Brazil. Data was collected primarily in a Conservation Unit (Estação Ecológica de Águas Emendadas) during the breeding season, between 2003 and 2007. We report and discuss details on 14 events of nest predation, 12 of which by passerines, mostly by curl-crested jays – Cyanocorax cristatellus (Temminck, 1823). The results of our study suggest that the role of birds as nest predators in the Cerrado has been underestimated and needs to be further investigated. KEY WORDS. Cerrado; bird; passerine.

DOI: http://dx.doi.org/10.15446/abc. v25n1.77442 ABSTRACT Several scientific reasons support continuing bird collection in Colombia, a megadiverse country with modest science financing. Despite the recognized value of biological collections for the rigorous study of biodiversity, there is scarce information on the monetary costs of specimens. We present results for three expeditions conducted in Santander (municipalities of Cimitarra, El Carmen de Chucurí, and Santa Barbara), Colombia, during 2018 to collect bird voucher specimens, quantifying the costs of obtaining such material. After a sampling effort of 1290 mist net hours and occasional collection using an airgun, we collected 300 bird voucher specimens, representing 117 species from 30 families.

We present the bird collection catalogue of the world fauna from the patrimony of the Zoological Museum of Cluj (founded in 1859). The studied collection includes 221 specimens belonging to 172 species, 59 families, 18 orders. Especially, we mention a small hummingbird collection made of 45 specimens, 38 species; some endemic species, three from Brazil (Malacoptila striata, Hemithraupis ruficapilla, Paroaria dominicana) and Apteryx oweni (New Zealand). Also, the collection includes other distinguished species as: Goura victoriae, Argusianus argus grayi, Tragopan melanocephalus, Lophophorus impejanus.
