Insects that give us wings
Although insects generally produce rejection and we associate them with annoying or harmful bugs, they are really fundamental animals for the planet since they pollinate most flowers (including our crops), eliminate manure and corpses, they are key in many trophic chains and could even serve as food. The following spoke: Jorge Mederos and Gloria Masó, […]
Climate change, critical level
Global warming has not stopped since the industrial revolution and in the Quèquicom we are also witnesses. In 2006 we dedicated a report to climate change. In 2019, thirteen years later, we made an update. We will see how has evolved the CO2 in the atmosphere, the temperature of the sea in Estartit, the fish […]
Fleas, ticks and bed bugs
Fleas, ticks and bedbugs are hematophagous invertebrates, that’s blood-eaters. Each has its own particular life cycle and preferences when itching. Apart from causing annoyance, they can transmit diseases of a certain severity like Lyme, and in exceptional cases, even to be mortal. The following spoke: Joaquim Castellà, parasitologist of the Department of Animal Health and […]
The butterfly effect
The weather in Catalonia depends on the atmospheric circulation in the middle of the North Atlantic, thousands of kilometers away. Any slight change in the initial conditions there will trigger a completely different result. This behavior, characteristic of chaotic systems, is known as the butterfly effect and is responsible for the unpredictablility of weather in […]
Evolution, after Darwin’s footsteps
Charles Darwin proposed natural selection as the mechanism of evolution, inspired by the finches of the Galapagos islands, fossils of Patagonia, or domestic pigeons. In Catalonia can be found completely equivalent examples: Pyrenean cave beetles, rodent fossils, or a new breed of mini-pigs intended for biomedical research.
Bees: a shared business in danger
Humans have a shared business with bees. We take care of, and they, in turn, produce honey, pollen, wax, propolis and royal jelly. Also pollinate our crops and flowers allow us to obtain the fruits. 40 years ago a hive gave 20 kg of honey per year and today gives only 15 kg. This is […]
Organic farming
Organic farming reverses the conventional agriculture. It uses invertebrates to combat pests, take profit of weeds and take care of all the underground ecosystem instead of seeing only as an inert support for the plants.
The Ports Mounts: land of goats and vultures
The reporter Pere Renom attends a spectacle of a safari: hundreds of vultures feast in one of the most extensive and wild mountainous areas of the Iberian Peninsula: the Ports. Also try to “catch” the emblematic animal of the natural park: the Hispanic goat.
