Wendy Foden
Wendy Foden is a conservation biologist, best known for her work on climate change impacts on biodiversity. Education While completing her master's degree at the University of Cape Town (2001), she discovered a latitudinal pattern of die-off of quiver trees (''Aloidendron dichotomum'') suggesting that climate change could be to blame. She received funding to further the study, working with Guy Midgley at the South African National Biodiversity Institute in Cape Town. Foden spent much of 2001–2003 surveying Quiver Trees in Namibia and the arid regions of western South Africa and set up long term monitoring to track changes. Her findings confirmed a clear trend of increasing mortality along gradients from south (polewards) to north (towards the equator) and from higher to lower altitudes, suggesting that the species is responding to a poleward shift in its suitable climate, but that colonization at the leading range edge is lagging. The study was published in 2007 and was one o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change And Ecosystems
Climate change has adversely affected both terrestrial and marine ecosystems, and is expected to further affect many ecosystems, including tundra, mangroves, coral reefs, caves etc. Increasing global temperature, more frequent occurrence of extreme weather, and rising sea level are among some of the effects of climate change that will have the most significant impact. Some of the possible consequences of these effects include species decline and extinction, change within ecosystems, increased prevalence of invasive species, a shift from forests being carbon sinks to carbon sources, ocean acidification, disruption of the water cycle, and increased occurrence of natural disasters, among others. General Climate change is affecting terrestrial ecoregions. Increasing global temperature means that ecosystems are changing; some species are being forced out of their habitats ( possibly to extinction) because of changing conditions. An example is migration. Due to the ever hotter weath ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2009 United Nations Climate Change Conference
The 2009 United Nations Climate Change Conference, commonly known as the Copenhagen Summit, was held at the Bella Center in Copenhagen, Denmark, between 7 and 18 December. The conference included the 15th session of the Conference of the Parties (COP 15) to the United Nations Framework Convention on Climate Change (UNFCCC) and the 5th session of the Conference of the Parties serving as the meeting of the Parties (CMP 5) to the Kyoto Protocol. According to the Bali Road Map, a framework for climate change mitigation beyond 2012 was to be agreed there. On Friday 18 December, the final day of the conference, international media reported that the climate talks were "in disarray". Media also reported that in lieu of a summit collapse, only a "weak political statement" was anticipated at the conclusion of the conference. The Copenhagen Accord was drafted by the United States, China, India, Brazil and South Africa on 18 December, and judged a "meaningful agreement" by the United States ...

South African Biologists
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant). Navigation By convention, the ''bottom or down-facing side'' of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Women Biologists
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as "women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men. Thro ...

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Ecological Society
The British Ecological Society is a learned society in the field of ecology that was founded in 1913. It is the oldest ecological society in the world. The Society's original objective was "to promote and foster the study of Ecology in its widest sense" and this remains the central theme guiding its activities today. The Society had, circa 2013 around 4,000 members of which 14% are students. Of its members, 42% are outside the United Kingdom, in a total of 92 countries. The head office is located in London. History The Society evolved out of the British Vegetation Committee, which was founded in 1904 to promote the survey and study of vegetation in the British Isles. This initiative was in turn the outcome of what many historians perceive to have been the emergence of modern ecology in the 1890s. The British Ecological Society's inaugural meeting was held at University College London on 12 April 1913 and was attended by 47 members. Sir Arthur Tansley became the first Presid ...

Stellenbosch University
Stellenbosch University ( af, Universiteit Stellenbosch) is a public research university situated in Stellenbosch, a town in the Western Cape province of South Africa. Stellenbosch is the oldest university in South Africa and the oldest extant university in Sub-Saharan Africa, together with the University of Cape Town - which received full university status on the same day in 1918. Stellenbosch University (abbreviated as SU) designed and manufactured Africa's first microsatellite, SUNSAT, launched in 1999. Stellenbosch University was the first African university to sign the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities. The students of Stellenbosch University are nicknamed "Maties". The term probably arises from the Afrikaans word "tamatie" (meaning tomato, and referring to the maroon sports uniforms and blazer colour). An alternative theory is that the term comes from the Afrikaans colloquialism ''maat'' (meaning "buddy" or "mate"), originally u ...

Climate Change Education
Climate change education (CCE) is education that aims to address and develop effective responses to climate change. It helps learners understand the causes and consequences of climate change, prepares them to live with the impacts of climate change and empowers learners to take appropriate actions to adopt more sustainable lifestyles. Climate change and climate change education are global challenges that can be anchored in the curriculum in order to provide local learning and widen up mindset shits on how climate change can be mitigated. In such as case CCE is more than climate change literacy but understanding ways of dealing with climate CCE helps policymakers understand the urgency and importance of putting mechanisms into place to combat climate change on a national and global scale. Communities learn about how climate change will affect them, what they can do to protect themselves from negative consequences, and how they can reduce their own climate footprint. In particular, ...

Albertine Rift
The Albertine Rift is the western branch of the East African Rift, covering parts of Uganda, the Democratic Republic of the Congo (DRC), Rwanda, Burundi and Tanzania. It extends from the northern end of Lake Albert to the southern end of Lake Tanganyika. The geographical term includes the valley and the surrounding mountains. Geology The Albertine Rift and the mountains are the result of tectonic movements that are gradually splitting the Somali Plate away from the rest of the African continent. The mountains surrounding the rift are composed of uplifted Pre-Cambrian basement rocks, overlaid in parts by recent volcanic rocks. Lakes and rivers The northern part of the rift is crossed by two large mountain ranges, the Rwenzori Mountains between Lake Albert and Lake Rutanzige (formerly Lake Edward) and the Virunga Mountains between Lake Rutanzige and Lake Kivu. The Virungas form a barrier between the Nile Basin to the north and east and the Congo Basin to the west and south. Lak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change Vulnerability
Climate change vulnerability (or climate vulnerability or climate risk vulnerability) is defined as the "propensity or predisposition to be adversely affected" by climate change. It can apply to humans but also to natural systems (ecosystems). Human and ecosystem vulnerability are interdependent.IPCC, 2022Summary for Policymakers .-O. Pörtner, D.C. Roberts, E.S.
