Messolonghi–Aitoliko Lagoons, Greece

-
Εικόνα
The Missolonghi-Aitoliko lagoons complex is located in the north part of the Gulf of Patras in the central west coast of Greece. It is one of the most important Mediterranean lagoons. It is a shallow area of 150 km2, extended between the Acheloos and Evinos rivers. It is protected by the Ramsar Convention and it is also included in the Natura 2000 network. The largest portion is the Kentriki Limnothalassa ("central lagoon") a shallow sea separated from the Gulf of Patras and the Ionian Sea by a chain of sand islands and is characterized as open type lagoon. To the north, the Aitoliko lagoon is connected to the central lagoon by a narrow “neck” and resembles a deep lake (depth 28 m) rather than a lagoon. The Anatoliki Klisova, Dytiki Klisova, as well as the western lagoons of the complex, namely Tholi and Palaiopotamos, are some shallow areas characterized as closed type lagoons. These communicate with the sea along channels and receives fresh water from the drainage p...

The Nervous System of Harriet Cole

This story, set in 1880s post Civil War America, particularly appealed to me due to my love of anatomy. The two main players in this unusual tale are very different individuals indeed. The first, Harriet Cole, was an African-American woman who worked as a cleaning lady at Hahnemann Medical College (now the Drexel University College of Medicine) in Philadelphia. The second, Dr Rufus B. Weaver, was the Medical College’s leading Professor of Anatomy. Together this odd couple would be responsible for the creation of one of the world’s most captivating and astonishing medical specimens. Harriet’s demise and generous donation In 1888, at just 35 years of age, Harriet Cole died from tuberculosis. Having worked for some time at the Medical College, she agreed to leave her body to Dr Weaver and requested that it be used for the benefit of science and medicine. It is very doubtful that Harriet knew what Dr Weaver would do with her body though, and the extraordinary legacy that she would leave be...

This is a tree that was struck by lightning and revealed its vascular system !! 🌳 Nature is so complicated. The vascular system of a tree transports water and minerals from the roots to the leaves ! As vascular plants, trees are organized into three major organs: the roots, the stems, and the leaves. The leaves are the principal photosynthetic organs of most higher vascular plants. They are attached by a continuous vascular system to the rest of the plant so that free exchange of nutrients, water, and end products of photosynthesis (oxygen and carbohydrates in particular) can be carried to its various parts. The stem is divided into nodes (points where leaves are or were attached) and internodes (the length of the stem between nodes). The leaves and stem together are called the shoot. Shoots can be separated into long shoots and short shoots on the basis of the distance between buds (internode length). The stem provides support, water and food conduction, and storage. Roots provide st...
