Johanna Mappes
Riitta Johanna Mappes (born 13 October 1965 in Valkeakoski, Finland) is an evolutionary ecologist based in Finland. Her research focuses on interspecific interactions, such as those between predators and prey. She is known for her work on the evolution of aposematic signals and mimicry in chemically defended prey, the evolution of signal polymorphism, the evolution of bacterial virulence, and the evolution of sexual and asexual reproduction. Her main study species include the wood tiger moth ('' Arctia plantaginis''), vipers (Viperidae), the Colorado potato beetle (''Leptinotarsa decemlineata'') and the drumming wolf-spider (''Hygrolycosa rubrofasciata''). Mappes earned her MSc degree in 1991 and her PhD in 1994, both from the University of Jyväskylä, Finland. Her doctoral thesis focused on reproductive tactics and maternal care in shield bugs, particularly the parent bug (''Elasmucha grisea''). In 2003 The Academy of Finland awarded Mappes the Young Dynamic Researcher Award' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolutionary Ecology
Evolutionary ecology lies at the intersection of ecology and evolutionary biology. It approaches the study of ecology in a way that explicitly considers the evolutionary histories of species and the interactions between them. Conversely, it can be seen as an approach to the study of evolution that incorporates an understanding of the interactions between the species under consideration. The main subfields of evolutionary ecology are life history evolution, sociobiology (the evolution of social behavior), the evolution of interspecific interactions (e.g. cooperation, predator–prey interactions, parasitism, mutualism) and the evolution of biodiversity and of ecological communities. Evolutionary ecology mostly considers two things: how interactions (both among species and between species and their physical environment) shape species through selection and adaptation, and the consequences of the resulting evolutionary change.

Parent Bug
''Elasmucha grisea'', common name parent bug, is a species of shield bugs or stink bugs belonging to the family Acanthosomatidae. The term parent bugs includes also the other species of the genus '' Elasmucha'' and some species of the family Acanthosomatidae. Subspecies Subspecies within ''Elasmucha grisea'' include: * ''Elasmucha grisea cypria'' Josifov, 1971 * ''Elasmucha grisea grisea'' (Linnaeus, 1758) Distribution ''Elasmucha grisea'' is a rather common and widespread species present in most of Europe. Description ''Elasmucha grisea'' can reach a length of . Males are smaller than females. These medium-sized shield bugs are usually brown-reddish, but there are also gray (hence the Latin species name ''grisea'') and green-brown specimens. The connexiva are black and white. The upper side is covered with several dark dots. The scutellum usually shows an evident black patch. The ventral face is largely punctuated with black. The lateral corners of the pronotum are simply bevel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Women Evolutionary 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 ...

Evolutionary Biologists
Evolutionary biology is the subfield of biology that studies the evolution, evolutionary processes (natural selection, common descent, speciation) that produced the Biodiversity, diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution is based on the theory that all species are related and they gradually change over time. In a population, the genetic variations affect the physical characteristics i.e. phenotypes of an organism. These changes in the phenotypes will be an advantage to some organisms, which will then be passed onto their offspring. Some examples of evolution in species over many generations are the Peppered moth, Peppered Moth and Flightless birds. In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called the Modern synthesis (20th century), modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics, a ...

Aposematism
Aposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defences which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous coloration, sounds, odours, or other perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually possesses chemical or physical defences is not the only way to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Novel World Method
The novel world method is a technique used in animal behaviour experiments that address questions on the evolution of warning signals (e.g. conspicuous colour patterns such as yellow and black stripes) that chemically defended prey (e.g. toxic insects) use to deter predators (i.e. aposematism), and also on warning signal mimicry. In the novel world, great tits (''Parus major'') are presented with a foraging task: they search and eat artificial prey in an indoor aviary built in a laboratory. The prey items are pieces of almond in paper shells that typically bear a black-and-white symbol as a signal (designed by the researcher) instead of a colour pattern. The prey are also presented on a black-and-white background. Novel world studies are “theoretical experiments” where for example the defence efficacy (bad taste), relative and absolute abundance, visibility or the degree of signal similarity of different prey types is manipulated, and the number of bird attacks on each prey type ...
