Hussein Adan Isack
Hussein Adan Isack (born 1957) is a naturalist and ethnobiologist living in Kenya, having been a research scientist in ornithology. Background and youth Hussein Adan Isack was born to parents who lived in the pastoral Northern region of Kenya. Throughout his youth Hussein developed and cultivated a keen interest in bird watching and began keeping birds at his home. His interest was further stimulated when he joined his high school where he met Paul Scholes, a biologist, himself an ardent birdwatcher from Liverpool. He reared falcons in school and would later become the leader of the wildlife clubs in his area. During his holidays, he would spend time pursuing his passion Later, he met Van Someren, an ornithologist with whom he worked with at the National Museum of Kenya paving way for a career spanning over 30 years. He was later awarded the Christopher Welch Scholarship for Natural Sciences at Oxford University, where he studied zoology and majored in behavioral ecology. It wa ...

Naturalist
Natural history is a domain of inquiry involving organisms, including animals, fungi, and plants, in their natural environment, leaning more towards observational than experimental methods of study. A person who studies natural history is called a naturalist or natural historian. Natural history encompasses scientific research but is not limited to it. It involves the systematic study of any category of natural objects or organisms, so while it dates from studies in the ancient Greco-Roman world and the mediaeval Arabic world, through to European Renaissance naturalists working in near isolation, today's natural history is a cross-discipline umbrella of many specialty sciences; e.g., geobiology has a strong multidisciplinary nature. Definitions Before 1900 The meaning of the English term "natural history" (a calque of the Latin ''historia naturalis'') has narrowed progressively with time, while, by contrast, the meaning of the related term "nature" has widened (see also ...

Zurich
Zurich (; ) is the list of cities in Switzerland, largest city in Switzerland and the capital of the canton of Zurich. It is in north-central Switzerland, at the northwestern tip of Lake Zurich. , the municipality had 448,664 inhabitants. The Urban agglomeration, urban area was home to 1.45 million people (2020), while the Zurich Metropolitan Area, Zurich metropolitan area had a total population of 2.1 million (2020). Zurich is a hub for railways, roads, and air traffic. Both Zurich Airport and Zürich Hauptbahnhof, Zurich's main railway station are the largest and busiest in the country. Permanently settled for over 2,000 years, Zurich was founded by the Roman Empire, Romans, who called it '. However, early settlements have been found dating back more than 6,400 years (although this only indicates human presence in the area and not the presence of a town that early). During the Middle Ages, Zurich gained the independent and privileged status of imperial immediacy and, in 1519 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Kenyan Scientists
The Demographics of Kenya is monitored by the Kenyan National Bureau of Statistics. Kenya is a multi-ethnic state in East Africa. Its total population was at 47,558,296 as of the 2019 census. A national census was conducted in 1999, although the results were never released. A new census was undertaken in 2009, but turned out to be controversial, as the questions about ethnic affiliation seemed inappropriate after the ethnic violence of the previous year. Preliminary results of the census were published in 2010. Kenya's population was reported as 47.6 million during the 2019 census compared to 38.6 million inhabitants 2009, 30.7 million in 1999, 21.4 million in 1989, and 15.3 million in 1979. This was an increase of a factor of 2.5 over 30 years, or an average growth rate of more than 3 percent per year. The population growth rate has been reported as reduced during the 2000s, and was estimated at 2.7 percent (as of 2010), resulting in an estimate of 46.5 million in 2016. As of ...

The Trials Of Life
''The Trials of Life: A Natural History of Behaviour'' is a BBC nature documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 3 October 1990. A study in animal behaviour, it was the third in a trilogy of major series (beginning with '' Life on Earth'') that took a broad overview of nature, rather than the more specialised surveys of Attenborough's later productions. Each of the twelve 50-minute episodes features a different aspect of the journey through life, from birth to adulthood and continuation of the species through reproduction. The series was produced by the BBC Natural History Unit in conjunction with the Australian Broadcasting Corporation and Turner Broadcasting System. The executive producer was Peter Jones and the music was composed by George Fenton. Part of David Attenborough's 'Life' series, it was preceded by '' The Living Planet'' (1984) and followed by '' Life in the Freezer'' (1993). Background The se ...

Daniel Toroitich Arap Moi
Daniel Toroitich arap Moi ( ; 2 September 1924 – 4 February 2020) was a Kenyan politician who served as the second president of Kenya from 1978 to 2002. He is the country's longest-serving president to date. Moi previously served as the third vice president of Kenya from 1967 to 1978 under President Jomo Kenyatta, becoming the president following the latter's death. Born into the Tugen sub-group of the Kalenjin people in the Kenyan Rift Valley, Moi studied as a boy at the Africa Inland Mission school before training as a teacher at the Tambach teachers training college, working in that profession until 1955. He then entered politics and was elected a member of the Legislative Council for Rift Valley. As independence approached, Moi joined the Kenyan delegation which travelled to London for the Lancaster House Conferences, where the country's first post-independence constitution was drafted. In 1960, he founded the Kenya African Democratic Union (KADU) as a rival party ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ewaso Ng'iro
Ewaso Ng'iro, also called Ewaso Nyiro, is a river in Kenya which rises on the west side of Mount Kenya and flows north, then east and finally south-east, passing through Somalia where it joins the Jubba River. The river's name is derived from the local community's Maasai language, and means river of brown or muddy water. Downstream, the intermittent stream in Somalia is also called Lagh Dera. The upper basin of the Ewaso Ng'iro River is . The river has a continuous water supply due to the glaciers on Mount Kenya. Ewaso Ng'iro feeds into Lake Ol Bolossat, the only lake in Nyandarua County and the larger Central Kenya, and crosses seven arid to semi-arid landscapes. It is characterized by vastly different physiographic features and species and has become a fundamental component to the survival of the wildlife, as well as the expansion of the human population and socio-economic developments. Water, the limited land resource provided by the Ewaso Ng’iro watershed, is unevenly d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ornithology
Ornithology, from Ancient Greek ὄρνις (''órnis''), meaning "bird", and -logy from λόγος (''lógos''), meaning "study", is a branch of zoology dedicated to the study of birds. Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guild (ecology), guilds, insular biogeography, phylogeography, and bird conservation, conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories.

Scientist
A scientist is a person who Scientific method, researches to advance knowledge in an Branches of science, area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century in science, 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different er ...

Honeyguide
Honeyguides (family (biology), family Indicatoridae) are a family of birds in the order Piciformes. They are also known as indicator birds, or honey birds, although the latter term is also used more narrowly to refer to species of the genus ''Prodotiscus''. They have an Old World tropical distribution, with the greatest number of species in Africa and two in Asia. These birds are best known for their interaction with humans. Honeyguides are noted and named for one or two species that will deliberately lead humans directly to bee colonies, so that they can feast on the grubs and beeswax that are left behind. Localized interaction between honeyguides and honey badgers has been reported. Taxonomy The Indicatoridae were noted for their barbet-like structure and brood-parasitic behavior and morphologically considered unique among the non-passerines in having nine primaries. The Phylogenetics, phylogenetic relationship between the honeyguides and the eight other families that make up t ...

Behavioral Ecology
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for ethology, animal behavior due to ecology, ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined Tinbergen's four questions, four questions to address when studying animal behaviors: what are the proximate causes, ontogeny, Adaption, survival value, and phylogeny of a behavior? If an organism has a trait that provides a selective advantage (i.e., has adaptive significance) in its environment, then natural selection favors it. Adaptive significance refers to the expression of a trait that affects fitness, measured by an individual's reproductive success. Adaptive traits are those that produce more copies of the individual's genes in future generations. Maladaptive traits are those that leave fewer. For example, if a bird that can call more loudly attracts more mates, then a loud call is an adaptive trait for that species because a louder bird mates ...
