This is a brief overview of the type of zoogeographic distributions of animals, such as cosmopolitan, discontinuous, endemic, isolated, and bipolar distributions.
Introduction
Ostracoderms (shell-skinned) are of several groups of extinct, primitive, jawless fishes that were covered in an armour of bony plates.
They appeared in the Cambrian, about 510 million years ago, and became extinct towards the end of the Devonian, about 377 million years ago. They were quite abundant during the upper Silurian and Devonian periods. Most of fossils of Ostracodermi were preserved in the bottom sediments of freshwater streams.
However, the opinion is sharply divided as to whether their habitat was freshwater or marine.
The first fossil fishes that were discovered were ostracoderms.
The Swiss anatomist Louis Agassiz received some fossils of bony armored fish from Scotland in the 1830s.
The ostracoderms resembled the present day cyclostomes (lampreys and hagfishes) in many respects and together with them constitute a special group of jawless vertebrates, the Agnatha.
Characteristics: They use gills exclusively for respiration but not for feeding . Earlier chordates with gills used them for both respiration and feeding. Ostracoderms had separate pharyngeal gill pouches along the side of the head, which were permanently open with no protective operculum. mostly small to medium-sized fishes, protected by a heavy, bony dermal (derived from skin) armor. bottom-dwellers; filter-feeders or grazers. no paired fins, but many with stabilizing paired flaps on either side of head.
(1) Ostracoderms were the first vertebrates.
(2) They were popularly called armoured fishes.
(4) They lived in freshwater.
(5) They were bottom dwellers.
(6) Their body was fish-like and did not exceed 30 cm in size.
(7) Paired fins were absent.
(8) Median and caudal fins were present.
(9) The caudal fin was of heterocercal type.
(10) The head and thorax were covered by heavy armour of bones. It protected ostracoderms from the giant scorpion like arthropods, eurypterids.
(11) Bony skull was well developed.
(12) Mouth was mostly present on the ventral side.
(13) They were having large number of gill slits.
(14) The nervous system had 10 pairs of cranial nerves.
(15) The head had a pair of lateral eyes, and a median pineal eye.
(16) They were filter feeders, feeding like a vacuum cleaner.
(17) The endoskeleton was either bony or cartilaginous.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

includes Common fox, Jackal, Jungle Cat,Chinkara
Gazelle, Urial, Monitor Lizard and Indian cobra
8. Hub Dam wild life sanctuary
Hub dam is Pakistan's third largest dam. This dam is situated in the north of Karachi
bordering the Kirthar National Park. A large water storage reservoir constructed in 1981
on the Hub River, in a region of arid plains and low stony hills. Much of the shoreline is
steeply shelving and stony, but there are many shallow bays and small islands. The
greater part of the reservoir (in Balochistan) is unprotected; the eastern shore and area
south of the Dam (in Sindh) are protected in the Kirthar National Park and Hub Dam
Wildlife Sanctuary., respectively. The lake formed by the dam covers an area of 32
square miles and is an ideal place for bird watching. There is plenty of waterfowl in the
lake,both resident and migratory. The surrounding hills are the home of Urial, Sind wild
goat, Chinkara gazelle, Wolf, Jackal, Common fox, Pangolin and numerous other birds
and reptiles.

10. Naltar Wildlife Sanctuary
covers 273 sq km of the Naltar Valley to its juncture with
the Hunza River, and is contiguous with the Pakora and
Sherqila Game Reserves (John Mock). A small population
of Astor Markhor is found here.
11. Nara Desert wildlife Santuary:
Nara desert provides refugee to a large number of wildlife in
Sind province. The Nara Canal Area, a chain of some 200 small, permanent
and seasonal,freshwater, brackish and saline lakes and marshes stretching for
about 150 km along either side of the Nara Canal from Sorah in the north to
Sanghar in the south is known to be of great importance for wintering waterfowl
and other wildlife, but few surveys and censuses have been carried out, except
at a few of the southernmost lakes. The largest population of the endangered
Mugger Crocodile in Pakistan is found here. Other animal life includes Jackal,
Fox, Pangolin, Honey Badger and Wolf.
12. Chasma and Taunsa Barrage Dolphin
Santuary
The Chashma and Taunsa Barrage are declared Wildlife Sanctuaries by the
Punjab government. A very important breeding, staging and wintering area for a
wide variety of waterfowl, including at least one threatened species
(Marmaronetta angustirostris). Mid-winter waterfowl counts in recent years
have regularly exceeded 20,000 birds. The endangered Indus Dolphin
(Platanista indi) occurs in the river both upstream and downstream of the
barrage. Since the 1970s, the population of the Indus Dolphin has significantly
increased here.
