Diversity of Protists I01:15

Diversity of Protists I

2.3K
Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Deep Sea Microbial Ecology

The deep ocean and its underlying sediments represent vast, largely unexplored microbial habitats that extend far beyond the sunlit photic zone. The photic (euphotic) zone typically spans the upper ~100–200 meters of pelagic waters in the open ocean, but its depth varies geographically and seasonally, where sufficient light supports photosynthetic life. Below this lies the deep sea, spanning roughly 1000–6000 meters (bathypelagic to abyssal zones), with deeper hadal trenches...

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...

Marine Microbial Ecology01:30

Marine Microbial Ecology

Marine microbial ecosystems are shaped by distinct physicochemical limits, including high salinity, low nutrient availability, and fluctuating oxygen levels. These conditions favor smaller microbial cell sizes, which maximize their surface-to-volume ratio for efficient nutrient uptake.Microbial activity and community composition are closely linked to biogeochemical cycles, particularly in dynamic environments like estuaries, where halotolerant microbes thrive in response to variable salinity...

Red Algae

1.9K
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
  • Climate change science
  • Ecosystem modeling

Background:

  • Climate change is projected to significantly alter marine phytoplankton communities, impacting marine food webs.
  • Current ecosystem models often assume phytoplankton species have fixed environmental preferences and do not adapt to changing conditions.
  • The capacity of phytoplankton to adapt evolutionarily to rapid climate change is largely unknown.

Purpose of the Study:

  • To investigate whether phytoplankton species can adapt their realized niches to track environmental changes.
  • To assess the adaptive capacity of dominant phytoplankton species to observed changes in temperature and irradiance.
  • To determine if phytoplankton exhibit adaptive responses to nutrient availability, specifically nitrate.

Main Methods:

  • Analysis of 15 years of observational data from Station CARIACO (Carbon Retention in a Colored Ocean).
  • Examination of shifts in realized niches of dominant phytoplankton species in response to environmental variables.
  • Comparison of adaptive responses to changes in water temperature, irradiance, and nitrate concentrations.

Main Results:

  • Most dominant phytoplankton species adapted their realized niches to track increases in water temperature and irradiance.
  • The majority of species showed a fixed niche for nitrate, indicating limited adaptation to nitrate availability changes.
  • Evidence suggests that phytoplankton possess some adaptive capacity, contrary to common modeling assumptions.

Conclusions:

  • Phytoplankton communities demonstrate an ability to adapt to certain aspects of climate change, such as warming and increased irradiance.
  • The fixed niche observed for nitrate suggests limitations in adaptive capacity for some crucial environmental factors.
  • Community ecosystem models must now consider the potential for phytoplankton adaptation, rather than assuming fixed environmental preferences.
