Marine Mammals and Sea Turtles The eastern Aegean region is home to a large number of marine mammals which are classified either as at risk or data deficient. This habitat is in desperate need of protection, as it is subjected to a wide range of anthropogenic threats.

The aim of Archipelagos is to better understand and monitor the habitat structure and population dynamics of cetaceans around the eastern Aegean islands. The Aegean, just like the whole Mediterranean Sea, is influenced by human activities such as shipping, tourism, unregulated fisheries practices and pollution, which threaten the survival of marine mammal populations.

A vital sector of the eastern Aegean economy are the fisheries, which cause an unavoidable interaction between the marine mammals and the fishermen who are after the same prey.

The main goals of our research are: Monitoring the habitat use, abundance and distribution of cetaceans, Mediterrenean monk seals and sea turtles. Studying the population structure and its dynamics.

Studying the behavior through visual and acoustic data.

Investigating the impact of major threats, such as fishing and tourism, on the cetacean behavior. Our current work includes the following activities: Conducting boat-based surveys to collect data on cetacean abundance, distribution and behavior.

Conducting land-based surveys to collect data on cetacean behavior and distribution without interacting with them. Collecting data about different types of marine vessels, their distance from the focal group, fishing activities and marine debris during the boat and land surveys.

Assessing the populations of resident, transient and seasonal cetaceans through photo-ID. Developing an online photo-ID network. Using a hydrophone to collect acoustic data.

Creating GIS maps to pinpoint critical habitats and understand the factors threatening them. Delivering first aid to the animals, rescuing them, performing necropsies and collecting data related to stranded individuals e.

Study Area The monitoring of marine mammal populations focuses on the sea around Samos and extends to the islands of Ikaria, Fourni, Patmos, Arki and Lipsi. From the research base of Pythagorio in Samos, land based surveys are also conducted from a number of observational points in different parts of the island.

The boats used by Archipelagos to carry out marine mammal surveys are anchored in Samos Marina, a little port next to the main research base. Research surveys can focus on: Sea turtle populations, including green turtles and loggerhead turtles.

General Monitoring The main task of the marine mammal team is to monitor the study area through both land and boat-based surveys in order to analyze the abundance, distribution and behavior of marine mammals and turtles.

Data on various human impacts marine vessels, fishing activity, debris are also collected. During surveys, the team is responsible for behavioral data collection, photographing individuals and later cataloging the photograph.

All these data are recorded and stored in a database at the main research base for later analysis. Photo Identification During marine mammal pods sightings, the Archipelagos marine mammal team gathers photographic material used for identifying individuals inhabiting the studied area. To facilitate this process, all pictures are sorted, cropped and named.

The identification is done by comparing different morphological aspects of the body and fin, such as patches of color, shape, scars, nicks, notches etc.

Once the individuals have been identified and classified, they are introduced into a photo-ID catalog which includes all the cetaceans spotted so far. As a result of this process, the team can get a better idea of the population size in the study area, compare it along the coming years and identify the social structure and residency pattern of target species.

As a result of this process, the team can get a better idea of the size of the population in the studied area and compare it along the coming years. Mediterranean Monk Seal Mediterranean monk seals are considered to be the second most endangered marine mammals in the world. It is estimated that only individuals remain.

Marine invertebrates make up most of the zooplankton and bottom fauna, and include a wide variety of animals such as sponges, jellyfish, coral, worms, starfish, and sea urchins. Analysis: 1. Some marine animals hide inside sponges, swimming in through the exhalant opening.

One of the most important surviving populations of the species resides along the Greek and Turkish coasts of the Aegean Sea.Marine invertebrates make up most of the zooplankton and bottom fauna, and include a wide variety of animals such as sponges, jellyfish, coral, worms, starfish, and sea urchins.

Analysis: 1. Some marine animals hide inside sponges, swimming in through the exhalant opening. Healthy marine species like whales, sea turtles, coral, and salmon are important for maintaining balanced and thriving ocean ecosystems. We work to prevent marine species populations from decline and extinction, protect them from human activities, and monitor activities that might impact them so they are around for future generations.

Optimal Egg Size in Marine Invertebrates: Theory and Phylogenetic Analysis of the Critical Relationship between Egg Size and Development Time in Echinoids Don R. Levitan *, and Department of Biological Science, Florida State University, Tallahassee, Florida ‐ In the twelve years since publication of Invertebrates, Second Edition, fundamental shifts have occurred in our understanding of the origins and evolutionary relationships among protists and regardbouddhiste.com changes are largely due to the explosion of molecular phylogenetics and evo-devo research, emergence of the new field of animal genomics, major fossil discoveries in China, Australia, and.

Marine ecosystems are among the largest of Earth's aquatic regardbouddhiste.comes include salt marshes, intertidal zones, estuaries, lagoons, mangroves, coral reefs, the deep sea, and the sea regardbouddhiste.com can be contrasted with freshwater ecosystems, which have a lower salt content.

Marine waters cover two-thirds of the surface of the Earth. Such places are considered ecosystems because the plant. The eastern Aegean region is home to a large number of marine mammals which are classified either as at risk or data deficient.
