Descriptions of two new species of nun birds from Panama

Two new species of Monasa are among the interesting birds collected by E. A. Goldman while working on the Smithsonian Biological Survey of Panama during the winter of 1911. They were collected at the same locality on the base of Cerro Azul, northwest from Chepo, and only a single specimen of each was obtained. No others were seen during the entire season in the Canal Zone and adjacent territory...(Document contains 4 pages)

A Biogeographic Assessment off North/Central California: To Support the Joint Management Plan Review for Cordell Bank, Gulf of the Farallones, and Monterey Bay National Marine Sanctuaries: Phase I - Marine Fishes, Birds and Mammals.

In the spring of 2001, NOAA’s National Marine Sanctuary Program (NMSP) and National Centers for Coastal Ocean Science (NCCOS), in consultation with the National Marine Fisheries Service (NMFS), launched a 24-month effort to define and assess biogeographic patterns of selected marine species found within and adjacent to the boundaries of three west coast National Marine Sanctuaries. These sanctuaries, Monterey Bay, Gulf of the Farallones, and Cordell Bank are conducting a joint review process to update sanctuary management plans. The management plans for these sanctuaries have not been updated for over ten years and the status of the natural resources and their management issues in and around the sanctuaries may have changed. In addition, significant accomplishments in research and resource assessments have been made within the region. Thus, it is important to incorporate new and expanding knowledge into the revised management plans for these Sanctuaries.

The transport of aquatic animals by birds. [Translation from: Binnengewaesser 18, 156-159, 1950.]

A great deal has been written on the part which birds play in the dispersal of freshwater fauna. This article summarises literature on the dispersal of aquatic animals by birds and aquatic insects.

Assembleia de aves consumidoras de frutos de sub-bosque em diferentes altitudes em uma área de Mata Atlântica no estado do Rio de Janeiro

Neste estudo, investigamos a distribuição altitudinal da composição, riqueza, abundância das espécies de aves consumidoras de frutos em cinco altitudes e avaliamosa influência da estrutura da vegetação nas diversidades de aves. O estudo foi realizado na Reserva Ecológica de Guapiaçu (REGUA) contígua ao Parque Estadual dos Três Picos (PEPT), no município de Cachoeiras de Macacu, RJ. Coletamos os dados das aves em 24 excursões a campo, incluindo seis bimensais (jul./2010 a maio/2011) e 18 mensais (jul./2011 a dez./2012). Para amostragem das aves, utilizamos o método de captura-marcação-recaptura com redes de neblina, expostas durante sete h/dia em cinco altitudesao longo de uma variação altitudinal de 1000 m. O esforço amostral foi de 8400 h-rede. Para amostragem da estrutura da vegetação, sorteamos três parcelas de 100 m2 adjacentes às linhas das redes em cada altitude, nas quais foram analisadas as densidades de diferentes hábitos de vida. Das árvores, arvoretas e arbustos coletamos as medidas de altura total e diâmetro da altura (no caso dos arbustos, o diâmetro foi coletado a 50 cm do solo). Capturamos 448 indivíduos correspondentes a 35 espécies de aves, distribuídas em 16 famílias. Destas, 26% são endêmicas de Mata Atlântica, incluindo quatro espécies categorizadas com algum grau de vulnerabilidade. Dezesseis espécies foram classificadas como frugívoras enquanto 19 como insetívoras-frugívoras. Leptopogon amaurocephalus, Mionectes rufiventris, Lanio melanops, Chiroxiphia caudata foram capturadas nas cinco altitudes, sendo as últimas duas espécies as mais abundantes. Registramos maior riqueza e abundância de aves nas altitudes de 370 e 770 m. A composição de aves diferiu entre as altitudes, sendo 170 e 1000 m as mais dissimilares. As espécies de aves insetívoras-frugívoras predominaram nos sub-bosques das cinco altitudes. Registramos deslocamento altitudinal de cinco espécies de aves, sendo o maior deslocamento realizado por um indivíduo de Attilarufus, capturado a 770 m e, recapturado a 370 m. Encontramos maior densidade de plantas no sub-bosque nas altitudes 170, 370 e 1000 m. Bambus foram registrados apenas a 1000 m, enquanto que as ervas foram limitadas às altitudes de 170 e 370 m. A estrutura da vegetação apresentou baixa similaridade entre as altitudes, principalmente devido a diferentes densidades das formas de vida e altura das plantas. Três altitudes, 170, 370 e 1000 m, apresentaram alta densidade de indivíduos no sub-bosque, sendo que esta última evidenciou uma estrutura da vegetação relativamente mais simples devido ao alto número de árvores de baixa altura, ao maior número de arvoretas e à presença de bambus. A diversidade de aves foi sensível à estrutura da vegetação, em especial à altura das árvores que apresentou um decréscimo da altura com o aumento da altitude. Esta relação entre a diversidade de aves e a estruturada da vegetação destaca a importância da preservação da estrutura da vegetação para a manutenção da diversidade de aves consumidoras de frutos da REGUA e do PETP

Removal of Sea Lettuce, Ulva spp., in Estuaries to Improve the Environments for Invertebrates, Fish, Wading Birds, and Eelgrass, Zostera marina

Mats (biomasses) of macroalgae, i.e. Ulva spp., Enteromorpha spp., Graciolaria spp., and Cladophora spp., have increased markedly over the past 50 years, and they cover much larger areas than they once did in many estuaries of the world. The increases are due to large inputs of pollutants, mainly nitrates. During the warm months, the mats lie loosely on shallow sand and mud flats mostly along shorelines. Ulva lactuca overwinters as buds attached to shells and stones, and in the spring it grows as thalli (leaf fronds). Mats eventually form that are several thalli thick. Few macroinvertebrates grow on the upper surfaces of their thalli due to toxins they produce, and few can survive beneath them. The fish, crabs, and wading birds that once used the flats to feed on the macroinvertebrates are denied these feeding grounds. The mats also grow over and kill mollusks and eelgrass, Zostera marina. An experiment was undertaken which showed that two removals of U. lactuca in a summer from a shallow flat in an estuarine cove maintained the bottom almost free of it.

A Biogeographic assessment off North/Central California: In support of the National Marine Sanctuaries of Cordell Bank, Gulf of the Farallones and Monterey Bay. Phase II - Environmental setting and update to marine birds and animals

NOAA’s National Centers for Coastal Ocean Science (NCCOS) conducts and supports research, monitoring, assessments, and technical assistance to meet NOAA’s coastal stewardship and management responsibilities. In 2001 the Biogeography Branch of NCCOS partnered with NOAA’s National Marine Sanctuary Program (NMSP) to conduct biogeographic assessments to support the management plan updates for the sanctuaries. The first biogeographic assessment conducted in this partnership focused on three sanctuaries off north/ central California: Cordell Bank, Gulf of the Farallones and Monterey Bay. Phase I of this assessment was conducted from 2001 to 2004, with the primary goal to identify and gather the best available data and information to characterize and identify important biological areas and time periods within the study area. The study area encompasses the three sanctuaries and extends along the coastal ocean off California from Pt. Arena to Pt. Sal (35°-39°N). This partnership project was lead by the NCCOS Biogeography Branch, but included over 90 contributors and 25 collaborating institutions. Phase I results include: 1) a report on the overall assessment that includes hundreds of maps, tables and analyses; 2) an ecological linkage report on the marine and estuarine ecosystems along the coast of north/central California, and 3) related geographic information system (GIS) data and other summary data files, which are available for viewing and download in several formats at the following website: http://ccma.nos.noaa.gov/products/biogeography/canms_cd/welcome.html Phase II (this report) was initiated in the Fall of 2004 to complete the analyses of marine mammals and update the marine bird colony information. Phase II resulted in significant updates to the bird and mammal chapters, as well as adding an environmental settings chapter, which contains new and existing data and maps on the study area. Specifically, the following Phase II topics and items were either revised or developed new for Phase II: •environmental, ecological settings – new maps on marine physiographic features, sea surface temperature and fronts, chlorophyll and productivity •all bird colony or roost maps, including a summary of marine bird colonies •updated at-sea data CDAS data set (1980-2003) •all mammal maps and descriptions •new overall density maps for eight mammal species •new summary pinniped rookery/haulout map •new maps on at-sea richness for cetaceans and pinnipeds •most text in the mammal chapter •new summary tables for mammals on population status and spatial and temporal patterns
