• The closer to humans and their infrastructure, the smaller the habitats used by various types of animals", summarises Martin Wikelski, director of the Max Planck Institute for Ornithology in Radolfzell. (mpg.de)

  • This lagoon is one of the tree lagoons in Baja where Gray Whales give birth and breed after their migration down the Pacific Coast from Alaska. (holbrooktravel.com)
  • Animals like urban foxes are more likely to find food when foraging in areas dominated by humans, which means that the distances they need to cover are much smaller than in the wild. (mpg.de)
  • A second reason for this development may have to do with changes to the animals' behaviour caused by the presence of humans. (mpg.de)

  • Avoiding people is the top priority of wildebeests and zebras making their annual migration across Africa's Serengeti-Mara, finds a new study that aims to understand how animals make decisions as they travel across the ecosystem. (scientificamerican.com)
  • Wildebeests and zebras alike went farther out of their way to dodge people than to avoid even animal predators like hyenas or lions-decisions that appear to be profoundly affecting their migration patterns. (scientificamerican.com)
  • Last month, the East African Court of Justice (EACJ) ruled against the so-called Serengeti Highway, which aims to carry up to 800 commercial vehicles a day across what is now the migratory path for millions of wildebeests, zebras, gazelles and other animals. (scientificamerican.com)
  • Humans, however, are increasingly limiting the range of movement of zebras and other animals. (mpg.de)
  • For example, from 1968 to 2004 a fence blocked the migration of zebras in the Okavango Delta in Botswana. (mpg.de)

  • Freshwater fishes also make short spawning migrations. (thefreedictionary.com)
  • The success or failure of individual animals to make the journey is usually needed for them to reproduce. (wikipedia.org)

  • Movebank" was created by biologists working with Martin Wikelski to track movement patterns of animals across the globe. (mpg.de)
  • The endocrine system is the key mediator of environmental and developmental (internal) information, and is likely to be involved in altering the performance of animals when selection has favored phenotypic plasticity. (usgs.gov)
  • This most recent sequence of geologic time is somewhat complicated to describe in terms of animal science since there is much more information available from the fossil record. (encyclopedia.com)
  • A type section is a place that is considered to be the first discovered well-defined area in which evidence of a time-period shift, or difference between plant and animal communities, can be observed. (encyclopedia.com)
  • Scientists can track the locations and movement of the tagged animals without recapturing them using this RFID technology or satellites. (wikipedia.org)
  • To keep track of the signal, the scientist follows the animal using the receiver. (wikipedia.org)
  • This approach of using radio tracking can be used to track the animal manually but is also used when animals are equipped with other payloads. (wikipedia.org)
  • Networks, or groups, of satellites are used to track animals. (wikipedia.org)

  • The eastern North American monarch population is notable for its annual southward late-summer/autumn migration from the northern and central United States and southern Canada to Florida and Mexico . (wikipedia.org)
  • Satellite tracking is especially useful because the scientists do not have to follow after the animal nor do they have to recover the tag to get the data on where the animal is going or has gone. (wikipedia.org)
  • Hopcraft said the migration study underscores how 'catastrophic' a road would be to the Serengeti's animals, forcing them to cross the road to access the Mara River, their only source of water in the dry season. (scientificamerican.com)
