Optimal Foraging00:48

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
Threats to Biodiversity01:50

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
Speciation Rates01:07

Speciation Rates

Speciation can proceed at markedly different rates, and evolutionary biologists commonly describe these differences through the models of gradualism and punctuated equilibrium. Both patterns explain how new species arise, but they differ in the tempo and continuity of evolutionary change. In both cases, evolutionary change arises from heritable variation within populations, with natural selection often shaping traits that improve survival and reproduction under specific environmental conditions.
Limits to Natural Selection01:38

Limits to Natural Selection

Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.For one, natural selection can only act upon existing genetic variation. Hypothetically, redtusks may enhance elephant survival by deterring ivory-seeking poachers. However, if there are no gene variants—or alleles—for redtusks, natural selection cannot increase the prevalence of...
Conservation of Declining Populations02:07

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.
Convergent Evolution01:54

Convergent Evolution

Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.The structures that arise from convergent evolution are called analogous structures. They are similar in function even if they are dissimilar in structure. Further, structures can be analogous while also...

Resumen

El pájaro dodo (Raphus cucullatus) probablemente se extinguió en 1690, casi 30 años después de su último avistamiento confirmado. Este estudio utiliza análisis estadísticos para determinar la fecha de extinción de esta famosa especie.

Área de la Ciencia:

  • Paleontología Paleontología.
  • Zoología Zoología Zoología.
  • Historia de la historia ecológica.

Sus antecedentes:

  • La extinción del dodo (Raphus cucullatus) es un evento bien conocido en la historia natural.
  • El último avistamiento confirmado del dodo fue en 1662, pero su fecha exacta de extinción sigue siendo incierta.

Objetivo del estudio:

  • Para determinar estadísticamente el tiempo real de extinción del dodo (Raphus cucullatus).
  • Para proporcionar una fecha más precisa para la extinción de esta especie icónica.

Principales métodos:

  • Utilizó un método estadístico para analizar las líneas de tiempo de extinción.
  • Datos de avistamientos históricos evaluados y rareza de la población.

  • El estudio estima que el año de extinción del dodo es 1690.
  • Esta fecha es aproximadamente 30 años más tarde que el último avistamiento confirmado en 1662.

Conclusiones:

  • El dodo (Raphus cucullatus) probablemente persistió durante varias décadas después de su último registro oficial.
  • El modelado estadístico ofrece un enfoque más preciso para la datación de extinciones de especies.
