Wildcat (Felis silvestris)

Did you know?

That the attempts of domestication of African Wildcat (Felis silvestris libyca) date back to the years 7,500 BC and that the ancient Egyptians worshiped cats as gods? The domestication of the cat may have begun as early as 8,000 BC.

Have been described many subspecies of wild cat, these can be grouped into: European Wildcats or the silvestris group;  Asian Wildcats or the ornata group; and the African wildcats or the libyca group.

The house cat is the domestic Egyptian cat belonging to the group, but domestic cats have blood also undoubtedly respective local subspecies.

The European Wildcats are larger and have a somewhat shorter tail than a house cat.The head-body length 55-80 cm is, is well furnished with a pompous tail of 25-40 cm. Males may have a body weight of 5 kg, while females weigh 3.5 to 4 kgs. The head is somewhat wider than that of a cat with a pink nose pad. There are two different parallel black lines on each cheek and forehead is scratched. The gray coat is thick. The coat is abundant woolly that is striped, yellowish on the upper part and throat, and underparts of whitish cream. The stripe pattern is clearer in kittens than in adults and the tail is tapered at the tip. At 3 months, they weigh 1.3 to 1.7 kg.

Fishing cat (Prionailurus viverrinus)

Did you know?

That the fisherman attracts fish with a cat scratching the surface of the water with its paw, mimicking the movements of insects? It then dives into the water to catch fish.They can also use their partially webbed feet to catch fish, frogs and other prey out of the water and swim underwater to take prey on ducks and other waterfowl.

This is a sturdy cat of small to medium size with an elongated head, with rather short legs and short tail. The head-body length is 70-86 cm, length 25-33 cm from the queue (ie, less than half of the head-body length), the height of 38-41 cm and the dimensions of the hind legs about 16 cm. Body weight varies from 7.7 to 15 kg. The head is large and broad, long face, with a hash brown on the nose. The iris is greenish and the pupils contract vertically. The ears are rather short and rounded. The front feet are webbed and moderately developed. The protection of the clutches is small.

The coat is short and thick. Its base color is gray or olive gray, tinged with brown. The dark elongated spots arranged in longitudinal rows extending throughout the body. Has 6-8 dark lines from the forehead to the neck, elbow and two different bars in the side of each front leg. The back of the ears is black with a conspicuous white spot. The tip of the tail is black. The belly is whitish, with spots.

After a gestation period of about 63 days, the female gives birth to a litter of usually two to three kittens. The Fishing Cat’s diet includes birds, small mammals, snakes, snails and fish.

African Cetónido (Pachnoda sinuata)

Did you know?

That there are 108 species of Pachnoda known to science, found across Africa to southern Europe and the Arabian Peninsula? The species most commonly bred in human care is the P. marginata. Other species kept in zoos are P. epiphiata, P.flaviventris, P. marginata, P. orphanula, P. Pilgrim, P. savignyi, and P. sinuata.

The African Cetónido has a square and robust body that is slightly flattened. It has a contrasting color design that deters predators from eating them. Its upper wings are still in flight. Adults reach a length of 25 mm. The female makes several balls of manure or compost and lays an egg in each. The larvae feed on the remains of small decaying plant and content of the roots of the plant of these balls, before becoming pupae. They feed on ripe fruit, and prefer roses, and therefore also known as ‘beetles of roses or fruits’. The beetle gets into the soft flesh and most mature fruits to extract the juices. There are several subspecies. The species, P. sinuata flaviventris is the most common. P.sinuata calceata lives in the succulent Karoo and Namib Pre-West / Northern Cape Province and Namibia.    


Bubble coral (Plerogyra sinuosa)

A Bubble Coral is a coral with large polyps. It can grow to 1.2 meters and produces a basal calcareous skeleton. Although there are many polyps, there is only one opening in its large mouth. It processes like bubbles with their tentacles extending to the surface to provide more space and light to symbiotic algae, called zooxanthellae, that make the green bubbles. These bubbles shrink overnight and the tentacles are expanded to 4-5 cm in order to capture food. The color is either green or blue. The fertilization is performed in the digestive cavity and planula larvae that are released through the mouth. The larvae is installed after a day and soon produce a calcareous basal plate. Within a couple of weeks, the tentacles grow.

Strawberry Anemone (Actinia fragacea)

Did you know?

That the California species, californica Corynactis share the same common name? In captivity, an anemone has lived for at least 18 years?

Strawberry Anemone is large with a foot wide, which can be 10 cm in diameter, as the crown of tentacles. The column is red to red dirty and stained green, yellow, blue or pink. The anemone points give this common name because they seem strawberry seeds. The tentacles are red, pink or purple. Warts type stains blue, white or pink, called acrorhagi, which bind to the gravel and stones may be present below the tentacles. The eggs are spherical and light beige. They feed on crustaceans, molluscs and fish. The mode of reproduction is still unknown. In captivity, an individual has been observed spawning eggs in large quantities. Therefore shrank, but regained its original size after 3 days. In winter, the strawberry anemone can migrate offshore, probably to prevent freezing.     


Mexico wants to turn trash into power plant

The Mexico City government launched the call for international tender to convert the recently closed landfill “The Bordo Poniente” a source of energy.

The notice provides for the granting of municipal solid waste found in the landfill of the city for the capture and use for 25 years of biogas generated by them for use as fuel and/or generate electricity.

The landfill, considered one of the world’s largest, was closed last December after 26 years of operation and having exceeded its maximum capacity of 16.9 million tons.

The bidding process

In the bidding process, which ends in August, priority will be given the option that provides for the construction of a biogas power plant, which requires “least subsidy”, and also meets the technical and environmental standards, said the city government said in a statement.

The mayor of Mexico City, Marcelo Ebrard’s leftist, said that the idea of ​​bidding is that other invest the resources to recover methane gas without using tax dollars.

Reduce 1.4 million tons of C02

This unprecedented project in Mexico will reduce about 1.4 million tons of carbon dioxide, the main greenhouse gas (GHG), said Martha Delgado, head of the Environment of Mexico City.

In the past three years local authorities launched a development plan for the utilization of waste from the landfill to reduce the arrival of waste.

Mexico City, which generates about 12,000 tons of garbage daily, has a population of about 20 million people including conurbation areas.

Greenpeace Calls on Mexico to Cancel Plans for Nuclear Projects

Greenpeace asked the Mexican government to recall the central crisis in Fukushima, Japan, and abandon plans to build new nuclear plants in the country.

“Today we remember the tragedy of Fukushima, we encourage you to give up nuclear plans for our country,” the agency in a letter Mexican Energy Minister Jordy Herrera.

The letter, delivered by a group of activists in the ministry, said that that agency recently announced plans to build two new nuclear plants in the country, in addition to the Laguna Verde in the current state of Veracruz.

Mexico’s nuclear future

The Mexican government recently released its National Energy Strategy 2012-2026, which includes the direction of the country’s energy development over the next 15 years, including the possibility of building two nuclear plants.

Greenpeace said in his message that nuclear power is “a costly and risky for electricity generation and its contribution to mitigating global warming is minimal.”

He said there is no technical problem, or economic power to prevent putting aside the option of nuclear energy and that the only problem is “political will”.

Abandoning nuclear energy is the alternative “more desirable from the standpoint of safety and environmental protection and health,” he added.

They ask for the welfare of the population

The international environmental organization insisted that the Minister of Energy has the “responsibility to promote the welfare of the Mexican people and encourage future nuclear-free environment, a future that is safe for future generations.”

This activity is part of the Greenpeace campaign launched in 19 countries to warn of the risk they pose for millions around 400 active reactors in the world and to commemorate the first anniversary of the nuclear crisis in Japan.

The Decrease in Glacial Dust Storms Accentuates

From Patagonia to Iceland’s shrinking glaciers, exposes soil from rising dust storms affecting marine life and the global climate, according to a recent study. “The growing presence of mineral aerosols at high latitudes is surprising,” said Joseph Prospero, a researcher at the University of Miami, who for decades has investigated the effect of dust on the global environment.

Prospero’s investigations have established that the dust that rises from tropical regions of Africa is transported much of southern and eastern United States each summer (northern hemisphere) and causes 75 to 80 percent of the dust that falls on Florida.

It goes back to glacial periods. This phenomenon is not only contemporary and sediment samples in the ground and deep ice show increases in activity of dust associated with the ice ages. “There is therefore considerable interest in the global distribution of dust sources, factors affecting dust emissions and the properties of the emitted particles,” said Prospero, who over the years has established over two dozen observation stations around the globe.

The research that Prospero has developed over the past six years in Iceland, has determined that “there are large dust storms that originate there and move north Atlantic Ocean.”

According to the researcher, a substantial increase in dust activity in Iceland as glaciers decrease due to global warming. “In a hundred years, there will be no glaciers there,” said Prospero.

The dust itself contributes to increasing the rate of decline of glaciers explained the scientist. “When the glaciers are strong and ‘clean’, color is white, bright, light refractory,” he said. “But when they start to gather dust in their grooves in the top of the glacier, it absorbs more heat from sunlight and melting more quickly.”

Prospero and his colleagues spent six years studying the island of Heimaey, South Iceland and taking measurements of dust particles, or aerosols in the air. The researchers identified frequent episodes of dust production in the region, which in some cases reach 20 micrograms of particles per cubic meter, and found that dust emissions from the island tend to be higher in the spring.
