Population Growth00:57

Population Growth

23.1K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Threats to Biodiversity

21.7K
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...

Fixed Action Patterns

16.0K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

Red Algae

2.0K
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

Overview of Algae

The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...

Area of Science:

  • Marine Biology
  • Toxicology
  • Ecology

Background:

  • Irukandji syndrome is a severe, potentially fatal condition caused by Irukandji jellyfish stings.
  • These jellyfish are small and transparent, making them difficult to detect in tropical waters worldwide.

Purpose of the Study:

  • To investigate the correlation between environmental conditions and Irukandji jellyfish blooms.
  • To develop a predictive model for Irukandji bloom occurrences based on weather patterns.

Main Methods:

  • Analysis of collated medical records of Irukandji jellyfish stings.
  • Correlation of sting data with local meteorological and oceanographic conditions, specifically wind patterns.

Main Results:

  • Irukandji blooms in coastal waters, particularly on the Great Barrier Reef, can be forecast using wind conditions.
  • Blooms frequently coincide with the relaxation of southeasterly trade winds, with near-zero alongshore wind preceding stings.

Conclusions:

  • Wind conditions provide a reliable basis for forecasting Irukandji bloom presence in coastal areas.
  • The findings support traditional ecological knowledge and offer a foundation for management strategies to mitigate Irukandji stings.
