Plateaustraat 22, Ghent, Belgium. Invasion ecology has much advanced since its early beginnings. Nevertheless, explanation, prediction, and management of biological invasions remain difficult.

One idea that comes to mind is that the sex ratio is even because many species have sex chromosomes, which segregate among the gametes that determine sex e. Example: Interlocus sexually antagonistic selection in water striders Our final example introduces a new feature, in which we suppose that individuals of different classes exhibit This is another example of evolutionary branching, where a population evolves toward a point at which a polymorphism arises Geritz et al.

Conceptual Frameworks and Methods for Advancing Invasion Ecology

Persistent genetic variation within populations presents an evolutionary problem, as natural selection and genetic drift tend to erode genetic diversity. Models of balancing selection were developed to account for the maintenance of genetic variation observed in natural populations. Negative frequency-dependent selection is a powerful type of balancing selection that maintains many natural polymorphisms, but it is also commonly misinterpreted. This review aims to clarify the processes underlying negative frequency-dependent selection, describe classes of polymorphisms that can and cannot result from these processes, and discuss the empirical data needed to accurately identify processes that generate or maintain diversity in nature. Finally, the importance of accurately describing the processes affecting genetic diversity within populations as it relates to research progress is considered. The evolutionary processes that have generated or are maintaining many examples of diversity in nature, however, remain obscure and often controversial Chesson,

Many of our ebooks are available for purchase from these online vendors:. Many of our ebooks are available through library electronic resources including these platforms:. Thirty years ago, biologists could get by with a rudimentary grasp of mathematics and modeling. Not so today. In seeking to answer fundamental questions about how biological systems function and change over time, the modern biologist is as likely to rely on sophisticated mathematical and computer-based models as traditional fieldwork.

Associated Data

Most evolutionary thinking is based on the notion of fitness and related ideas such as fitness landscapes and evolutionary optima. Nevertheless, it is often unclear what fitness actually is, and its meaning often depends on the context. Here we argue that fitness should not be a basal ingredient in verbal or mathematical descriptions of evolution. Instead, we propose that evolutionary birth-death processes, in which individuals give birth and die at ever-changing rates, should be the basis of evolutionary theory, because such processes capture the fundamental events that generate evolutionary dynamics. In evolutionary birth-death processes, fitness is at best a derived quantity, and owing to the potential complexity of such processes, there is no guarantee that there is a simple scalar, such as fitness, that would describe long-term evolutionary outcomes.

Evolutionary game theory EGT is the application of game theory to evolving populations in biology. It defines a framework of contests, strategies, and analytics into which Darwinian competition can be modelled. Price 's formalisation of contests, analysed as strategies, and the mathematical criteria that can be used to predict the results of competing strategies. Evolutionary game theory differs from classical game theory in focusing more on the dynamics of strategy change. Evolutionary game theory has helped to explain the basis of altruistic behaviours in Darwinian evolution. It has in turn become of interest to economists , sociologists , anthropologists , and philosophers. Classical non-cooperative game theory was conceived by John von Neumann to determine optimal strategies in competitions between adversaries.

Negative Frequency-Dependent Selection Is Frequently Confounding

Adult gliomas are aggressive brain tumours associated with low patient survival rates and limited life expectancy. The most important hallmark of this type of tumour is its invasive behaviour, characterized by a markedly phenotypic plasticity, infiltrative tumour morphologies and the ability of malignant progression from low- to high-grade tumour types. Indeed, the widespread infiltration of healthy brain tissue by glioma cells is largely responsible for poor prognosis and the difficulty of finding curative therapies. Meanwhile, mathematical models have been established to analyse potential mechanisms of glioma invasion. In this review, we start with a brief introduction to current biological knowledge about glioma invasion, and then critically review and highlight future challenges for mathematical models of glioma invasion.

 - Мне нужен совет. Джабба встряхнул бутылочку с острой приправой Доктор Пеппер.

 Ну ладно, - вздохнул Стратмор.  - Похоже, вышла какая-то путаница.  - Он положил руку на плечо Чатрукьяна и проводил его к двери.  - Тебе не нужно оставаться до конца смены.

В его ушах звучали слова Стратмора: Не звони, пока не добудешь кольцо.

Когда толпа приблизилась к мощным каменным стенам почти вплотную, Беккер снова попытался вырваться, но течение стало еще более интенсивным. Трепет ожидания, волны, сносившие его то влево, то вправо, закрытые глаза, почти беззвучное движение губ в молитве. Он попытался вернуться назад, но совладать с мощным потоком было невозможно - все равно как плыть против сильного течения могучей реки. Беккер обернулся.
