Introduction
Andrés Beita-Jiménez is studying a M.Sc in Fisheries Stock Assessment at the Marine Institute, Memorial University of Newfoundland. Andrés does research in Fisheries, Quantitative Marine Ecology, and Marine Conservation. His current project is 'Spatiotemporal variability in northern shrimp life-history traits in Newfoundland and Labrador, Canada.'

The goal is to quantify spatiotemporal variation in biological traits affecting stocks’ productivity, including size structure, maturity and fecundity. The relation of this variations with changes in the environment and fishing pressure will be explored.

Studies of mixed-species groups of animals can reveal emergent complexities of collective behaviors. In this study we collected data on mixed-species hunting groups composed primarily of piscivorous fishes (species composition, abundance, behavioral interactions) and used both multivariate and network analyses to quantify pair-wise and guild level...

In recent years, there has been a health decrease in marine ecosystems. Due to this accelerated degradation, there is a more pressing need to investigate the effectiveness of MPAs in these degraded zones. In this work, we evaluate the effect of MPAs over species richness, biomass and size of reef fishes. The sampling was conducted in 31 sites in th...

When conservation can keep up with development´s pace: Health status of coral ecosystems in the North Pacific of Costa Rica. Coral reefs are diverse and productive ecosystems, despite this, they are being threatened by human activities that enhance the detrimental impact of the natural phenomenon's like Harmful Algal Blooms (HAB). The north Pacific...

Coral reefs of Isla del Coco National Park, Costa Rica: structure and comparison (1987-2014). Isla del Coco has one of the most diverse and well conserved coral reefs in Costa Rica. These reefs have been extensively studied since the 1980’s, however those studies focused mainly on coral coverage. The aim of this study is to evaluate the coral reefs...

Coloration patterns of reef fishes are an important trait for mediating intra and interspecific interactions, as well as for taxonomic identifications. Here we report a specimen of Stegastes arcifrons that presented a previously unobserved and anomalous color variation on a coral reef at Isla del Coco, Pacific Costa Rica. This color variation is kn...
here there is an example but there is in spanish. May be in the abstract you can find useful information. also you can see how do the flower look
In have used a relation between occurrence and abundance to categorize the species as rare, common, predominant and occasional. in the page 223 of the paper in the link you can find how i did it, in case that it can be helpful.
There are well documented cases of parthenogenesis in marine species. for example, here there are a couple of papers about parthenogenesis in sharks.

The Pacific coast of Costa Rica observes different management approaches. North Pacific region presents a high-density, disorganize, big-size coastal development where local communities have had limited decision-making power and marine protected areas (MPAs) are created but barely implemented. Southern region shows a better-controlled, medium-size...

Osa Conservation Area (Costa Rica) coral ecosystems: structure and conservation needs. Costa Rica is considered one of the 20 most biodiverse countries in the world, which includes it´s well known reefs ecosystems. Specifically, the South Pacific region, the Osa Conservation Area (ACOSA), holds one of the richest reefs of the country. Even though m...

Costa Rica is considered one of the 20 most biodiverse countries in the world, which includes its well known reefs ecosystems. Specifically, the South Pacific region, the Osa Conservation Area (ACOSA), holds one of the richest reefs of the country. Even though many of these reefs have been studied since the 1980s, most of them had focused mainly on...

Economic activities that depend on ichthyofauna in the North Pacific of Costa Rica. The North Pacific of Costa Rica is characterized by a large diversity of fish species. This diversity sustains two of the main economic activities developed there: fishing and tourism. We synthesized information from: semi-structured interviews with local stakeholde...

La disminución de los recursos marinos a nivel mundial y regional es una realidad que afecta el entorno ecológico y social de muchos países del mundo, incluyendo Costa Rica. Reconociendo la necesidad de obtener más información sobre los ecosistemas de aguas profundas, se realizaron dos cruceros con barcos camaroneros a lo largo de toda la costa del...

Pandalid shrimps are common representatives in many deepwater fisheries, including the Pacific area of Central America. However, our knowledge on the reproductive biology of these species is limited, especially considering those inhabiting the eastern tropical Pacific. We studied the egg production of Pantomus affinis (N= 29) and Plesionika trispin...
