Mangrove forest structure and sediment characteristics were examined in the extensive mangroves of Bocas del Toro, Republic of Panama. Forest structure was characterized to determine if spatial vegetation patterns were repeated over the Bocas del Toro landscape. Using a series of permanent plots and transects we found that the forests of Bocas del Toro were dominated by Rhizophora maugle with very few individuals of Avicennia germinans and Laguncularia racemosa. Despite this low species diversity, there was large variation in forest structure and in edaphic conditions (salinity, concentration of available phosphorus, Eh and sulphide concentration). Aboveground biomass varied 20-fold, from 6.8 Mg ha(-1) in dwarf forests to 194.3 Mg ha(-1) in the forests fringing the land. But variation in forest structure was predictable across the intertidal zone. There was a strong tree height gradient from seaward fringe (mean tree height 3.9 m), decreasing in stature in the interior dwarf forests (mean tree height 0.7 m), and increasing in stature in forests adjacent to the terrestrial forest (mean tree height 4.1 m). The predictable variation in forest structure emerges due to the complex interactions among edaphic and plant factors. Identifying predictable patterns in forest structure will aid in scaling up the ecosystem services provided by mangrove forests in coastal landscapes.
A Site Description of the CARICOMP Mangrove, Seagrass and Coral Reef Sites in Bocas del Toro, Panama
Resumo:
Bocas del Toro is located in the western region of the Republic of Panama. It is part of a province of approximately 8917 km(2) with an estimated 68% of its area covered by tropical rainforest. The area receives 2870 mm/year of rainfall. The dry and rainy seasons are not clearly defined. There are two periods each of low and high rainfall, March and September-October, and July and December, respectively. Mangrove forests, seagrass meadows and coral reefs are vast, covering large areas in the shallow waters surrounding the islands of the archipelago and along the mainland coast. The CARICOMP sites were established in 1998-99 and are periodically monitored following Level I protocol. Herein we describe the sites in a regional context and present the baseline data for each site. This paper fulfills the requirements of the formal site description for CARICOMP monitoring sites.

Los factores que influyen en la crioconservación de semen son la calidad, el manejo y los métodos de congelación (Lozano, 2009). La supervivencia y vitalidad espermática post-descongelación en la crioconservación está relacionada con los protocolos de procesamiento del semen y la dilución (Andrabi, 2009). Existen parámetros que permiten valorar la calidad seminal como la Motilidad Individual Progresiva (MIP), la Vitalidad Espermática (VE) y la tasa de Anormalidades en el semen descongelado que se ven afectados por los tiempos de equilibrio. Además la motilidad espermática y la vitalidad post-descongelación se pueden ver afectadas con el uso de los diferentes diluyentes tanto sintéticos (lecitina de soya) como orgánicos (yema de huevo). El objetivo fue comparar la eficacia del diluyente AndroMed® (TRIS + Lecitina de soya) y Triladyl® (TRIS + Yema de Huevo) y tres tiempos de equilibramiento de acuerdo a los protocolos establecidos en la crioconservación de semen de toro.
