Algal Bloom

A new study finds that elephants died 4 years ago in Botswana from drinking water poisoned by an explosion of toxic algae populations in the water pans due to the effects of climate change.

Algae

  • Algae are microscopic organisms that live in aquatic environments and use photosynthesis to produce energy from sunlight, just like plants.
  • Algae can be found in all types of natural waters, including salt water, fresh water, and brackish water (a mix of salt and fresh water).
  • Influencing factors - A few types of algae produce toxins. In these algae, toxin production can be stimulated by environmental factors such as light, temperature, salinity, pH, and nutrient levels.

Algal bloom

  • An algal bloom is a rapid increase in the density of algae in a body of water, such as a lake, river, or bay.
  • They are caused by diverse organisms, including toxic and noxious phytoplankton, cyanobacteria, benthic algae, and macroalgae.
  • Algal blooms occur when environmental conditions allow explosive growth of phytoplankton a bloom that can change the color of ocean water.
  • Responsible environmental factors include
    • Bright sunlight
    • High nutrient levels
    • Calm waters (low wind and circulation)
    • Limited number of grazers or predators
  • Other environmental factors can be temperature and salinity, which influence HABs differently but may help in determining the sources of blooms.
  • Each type of algae has its own preferences of environmental factors; that is, the recipe changes depending on the species.
  • Generally, there are 3 kinds of algal blooms - red, brown and green.

Red tides

Green tides

Brown Tides

Red tides are caused by phytoplankton that have a reddish pigment called peridinin.

Most dinoflagellates, such as Alexandrium catenella, have this pigment.

As a result, when there is a bloom of this dinoflagellate, the ocean will generally turn red.

It is common on both the east and west coasts of the U.S. as well as Florida and the Gulf of Mexico.

Green tides can be caused by Phaeocystis, which is a unicellular, photosynthetic algae found throughout the world.

Green tides can also be caused by macroalgae such as Enteromorpha spp. and Codium isthmocladum, which have caused serious damage to many coastal regions.

When in bloom, macroalgae often outcompete seagrass and coral reefs.

 

Brown tides are caused by the pelagophytes (another type of microalgae) such as Aureococcus anophagefferens.

Aureococcusis a spherical, non-motile species that has caused noticeable damage to the coastal ecosystems in which it occurs.

Brown tides are commonly seen in the northeast and mid-Atlantic U.S. estuaries.

Madhav National Park

National Tiger Conservation Authority (NTCA) has granted in-principle approval for the designation of Madhav National Park in Shivpuri district as a Tiger Reserve.

  • Madhav National Park will be the 9th tiger reserve in Madhya Pradesh.

  • Highest point - George Castle, built by Jivaji Rao Scindia of the Gwalior Royal family.
  • Forest type - Northern tropical dry deciduous mixed forests as well as Dry Thorn Forests typical of North – Western Madhya Pradesh.
  • Champion and Seth system of classification, they are classified under the category 5B/C2.

Champion and Seth's system of classification systematically categorizes forest types in India into 6 major categories based on factors such as climate, physiognomy, species composition, phenology, and topography.

  • Trees - Important species in the park are Kardhai, Salai, Dhaora and Khair.
  • The understory comprises almost entirely of Ber, Makor and Karonda. The jamun and mahua are found along the nullahs.
  • Animals - The forest is home to antelopes like Nilgai, Chinkara and Chowsinga and Deer including Chital, Sambar and Barking Deer.
  • Animals like the Leopard, Wolf, Jackal, Fox, Wild Dog, Wild Pig, Porcupine, Python etc are also sighted in the park.
  • Madhav National Park has made significant strides in tiger conservation.
  • After a successful breeding program, the park welcomed tiger cubs in September 2024, marking a historic moment in its restoration efforts.
  • Madhya Pradesh government yet to notify Ratapani wildlife sanctuary will be 8th tiger reserve despite awaiting government notification.
  • NTCA had accorded in-principle approval for declaring Ratapani wildlife sanctuary as a tiger reserve way back in August, 2008.
  • Other tiger reserves in Madhya Pradesh - Kanha, Satpura, Bandhavgarh, Pench, Sanjay Dubri, Panna and Veerangana Durgavati.

Tiger reserves in MP

  • Tiger population in states - According to National Tiger Conservation Authority and Wildlife Institute of India, Madhya Pradesh has 785 tigers, the highest in the country.
  • The state is followed by Karnataka (563) and Uttarakhand (560).
