Canary Islands Stonechat
The Canary Islands stonechat (''Saxicola dacotiae''), also known as the Fuerteventura stonechat or Fuerteventura chat, and formerly known as the Canary Islands chat due to its once widespread distribution on the Canary Islands, is a sedentary resident bird found only on the island of Fuerteventura where it is known as the ''Caldereta''. Taxonomy The Canary Islands stonechat is a small passerine bird that was classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher in the Muscicapidae. It, and similar small European species, are often called chats. It was included in the "common stonechat" (''Saxicola torquata''), but it is quite distinct; it is likely to be an insular derivative of ancestral European stonechats that colonised the islands some 1-2 mya, during the Early Pleistocene (Wink ''et al.'' 2002). Description The Canary Islands stonechat is intermediate in appearance between the European stonechat and the wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuerteventura
Fuerteventura () is one of the Canary Islands, in the Atlantic Ocean, part of the North Africa region, and politically part of Spain. It is located away from the northwestern coast of Africa. The island was declared a biosphere reserve by UNESCO in 2009. Fuerteventura belongs to Province of Las Palmas, one of the two provinces that form the autonomous community of the Canary Islands. The island's capital is Puerto del Rosario, where the Insule Council is found, the government of the island. Fuerteventura has 119,732 inhabitants (), the fourth largest population of the Canary Islands and the third of the Province. At , it is the second largest of the Canary Islands, after Tenerife. From a geological point of view, Fuerteventura is the oldest island in the archipelago. Toponymy The island's name is a compound word formed by the Spanish words for "strong" (fuerte) and "fortune" (ventura). Traditionally, Fuerteventura's name has been regarded as a reference to the strong winds aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat (ecology)
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desertification
Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid. It is the spread of arid areas caused by a variety of factors, such as climate change and overexploitation of soil as a result of human activity. Throughout geological history, the development of deserts has occurred naturally. In recent times, the potential influences of human activity, improper land management, deforestation and climate change on desertification is the subject of many scientific investigations. Definitions of words As recently as 2005, considerable controversy existed over the proper definition of the term "desertification." Helmut Geist (2005) identified more than 100 formal definitions. The most widely acceptedGeist (2005)p. 2/ref> of these was that of the Princeton University Dictionary which defined it as "the process of fertile land ''transforming into ...

Small Population Size
Small populations can behave differently from larger populations. They are often the result of population bottlenecks from larger populations, leading to loss of heterozygosity and reduced genetic diversity and loss or fixation of alleles and shifts in allele frequencies. A small population is then more susceptible to demographic and genetic stochastic events, which can impact the long-term survival of the population. Therefore, small populations are often considered at risk of endangerment or extinction, and are often of conservation concern. Demographic effects The influence of stochastic variation in demographic (reproductive and mortality) rates is much higher for small populations than large ones. Stochastic variation in demographic rates causes small populations to fluctuate randomly in size. This variation could be a result of unequal sex ratios, high variance in family size, inbreeding or fluctuating population size.Frankham, R., Briscoe, D. A., & Ballou, J. D. (2002). ...

Jandía
Jandía is a peninsula in the southwestern part of the island of Fuerteventura in the Canary Islands. The peninsula is entirely in the municipality of Pájara. Within the peninsula is Fuerteventura's tallest mountain, Pico de Jandía or ''Pico de la Zarza'', that rises to an elevation of 807 m. Jandía is connected with the rest of Fuerteventura through the isthmus ''Istmo de la Pared''. Most of the peninsula has been a nature reserve (''Parque Natural de Jandía'') since 1987. pages 9716 and 9851-4 On the south and east coasts of Jandía there are the beach resorts and |
Tourism
Tourism is travel for pleasure or business; also the theory and practice of touring (other), touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tour (other), tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be Domestic tourism, domestic (within the traveller's own country) or International tourism, international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of t ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
