Condición: NEW. 224, 115 col illus. . PB. NEW. . Covers spiders that live in our houses and apartments as lodgers. Mostly ignored and sometimes (wrongly) feared, there is hardly a building in the world that does not harbour some species of spider. What is fascinating is that we always find the same species. These spiders must have special adaptations, because the humidity in our homes is far too low, they are too clean, and the food supply is usually scarce. However, those spiders that have made the leap into our four walls are rewarded with a worldwide right to stay. This, in turn, is due to people's eagerness to trade and migrate worldwide: Humans tirelessly transport their belongings and an endless stream of goods around the world in sacks, parcels and containers. And our domestic spiders, as stowaways, travel just as tirelessly and unrecognized. It is therefore possible to present domestic spiders found throughout the world in a single book, as they are essentially the same everywhere. The 50 or so most important species and species groups are presented here in a generally understandable way, with a detailed profile, photos and distribution maps.The authors of this book are experts who work at museums, universities and in administration in Europe and North America. They are not only recognized scientists, but have also been avowed spider fans for decades. [9783031704475].

Spiders are super predators and devour everything they can overpower. To do this, they have developed incredibly good catching techniques and, with spider silk, a tool that makes material technology green with envy. The males are usually smaller than the females and, in order to have sex, they have to come up with a lot to avoid being misunderstood as easy prey: Dancing, drumming, and gifts almost always help. Spiders use their venom in very precise doses, and since humans are not on their menu, they are harmless to us. Many people's (unnecessary) fear of spiders finds cultural roots as early as the Middle Ages. Nevertheless, spider fear is easily treatable. There is no habitat or building without spiders. And that's a good thing because spiders have fascinating properties and their world is full of surprises. Everything you need to know about them is explained in this book in understandable language by experts for laymen. In addition, some of the most common spider species in the house and garden are briefly presented with tips for observation. Berlin, Heidelberg. Springer. 245 pp., 151 color & 12 b/w photos and illustrations, tables, hardback gr. 8 [16 x 24 cm].
