Taiga This is going to be about taigas. Some of it being about the locations of the taiga. Different ones being the characteristics, and soil. Others are about the plants, and animals. Then it will be about the food chain.…
It lays 1-3 eggs in it’s nest which is then sat on by the female most of the time until the eggs hatch. It has a better chance of reproducing higher in the mountains, especially when they choose to nest on a native tree called the Ohi. The breeding season is from March through September, and if a pair is together for one year they will most likely stay together for the rest of their life. They will keep their baby for about 7-9 weeks before they let them go. They are very territorial and can attack anything they feel that threatens them.…
Nevertheless, breeding has been noted to happen during summer time around May to July at the Pacific Grove in California. Spawning takes place once per breeding season (Ophiothrix SIMoN.) Spiny brittle stars hold no gestation because sperms and eggs are respectively released into water, where the fertilized eggs go through early development and develop into larvae (Hunt.) As stated, even though the eggs and sperms are sometimes retained in the bursae, the fertilized eggs are released into the plankton and invest no parental care. When the eggs hatch, ophioplutei feed themselves for several weeks on plankton and go through metamorphosis to fully develop into adult brittle stars (Brittle…
Background: Isopods, or what are often called pill bugs, are crustaceans. Isopods live in damp environments. They can be found under rocks, logs and in soil. In this lab, 10 isopods were given a choice between salt water or regular water chambers to test their preference. The results were recorded every 30 seconds over a period of 10 minutes.…
She stays in the safety of the burrow for about a week until her new shell hardens. After mating, the female stores the sperm for many months. When she is ready to lay her eggs, she turns onto her back and cups her tail. As many as 10,000 to 20,000 eggs are pressured out of her ovaries. They are fertilized as they pass through the sperm receptacle.…
California Sea Lions (Zalophus californianus) are one of the rehabilitated animals in Southern California. The brain lesions in So Coal Pinnipeds are among several reported causes of their morbidity and mortality within the last few decades. They generally range from traumatic, to inflammatory ( encephalitis) and degenerative brain lesions (encephalopathies). The overall brain lesions in Pinnipeds have been attributed to various microorganisms (viruses, bacteria, fungi, protozoa) and toxins, some of which are transferable to humans and can cause zoonotic diseases.…
Daphnia pulex are tiny aquatic crustaceans which have a translucent body which allows us to observe their internal organs in thorough detail. Daphnia is alleged to be a substitute of a human being in this experiment to examine the effects of chemicals on a heart of beings or other species for that matter . This will be measured by the heart rate as the heart rate is the contraction in one complete cardiac cycle. Furthermore Daphnia pulex is the most common species of water flea, an organism which can be found in almost every permanent, eutrophic water body. Generally Daphnia are freshwater organisms.…
In our study, we had two controls that we placed the Lumbriculus variegatus into. First, we used spring water to get the normal heart rate of the worms. The other control was a caffeine solution that served as our positive control. Our other solutions that we exposed the worms to consisted of increasing concentrations of two different NSAIDs (ibuprofen and aspirin). For each NSAID, we had a solution equivalent to the recommended dosage for a person based on body weight (the proportional dosage solution), ten times the concentration of this initial solution based on the body weight of the worm, and one-hundred times the concentration of the solution based on the average weight of Lumbriculus variegatus.…
Ardipithecus ramidus was around 4.4 mya. They were located in Ethiopia. Their appearances included a skull, teeth postcranial bones found. Although, they still have small brains. Their femur and pelvis made it possible for bipedalism.…
Sea Cucumbers, or Holouridea, have a mostly simple life cycle. Most warm water species breed by spawning or releasing sperm and eggs into the water. Once the eggs have hatched the larvae will reach grow into their first larval stage within 3 days. Most sea cucumber live to be between 5 to 10 years old. The breeding peaks for sea cucumbers are from March to may and November to December (James, JRank, Mulcrone).…
Stereolepis gigas reproduce asexually. Although the reproduction process for the Giant sea bass has not really been observed in the field, one study showed that when born, there is 2-20 fish. When impregnated, it only takes 3 months for the female to produce up to 60,000,000 eggs. The spawning period is between the months of July and September. After the eggs are laid, they swell up and absorb water, become buoyant, and float up to the surface.…
The three-spined stickleback fish is a well known fish to Alaskans it has two pointy spikes on its back and it is a yellowish brown color. It is located in the Pacific Ocean and some salt water lakes near Alaska. The first recorded spotting of the stickleback was in 1964. The rates of fish being caught near Alaska have been recorded for many years and the rate of stickleback caught in the 1990's is double what is being caught now. Mating occurs in early spring and summer for these fish and it starts with the male building a hollow nest with seaweeds or aquatic plants.…
Imagine having glowing parts at night in your body. Having the ability to glow in the dark would be fun. There are many things in the world that glow in the dark. For example, glow sticks, lightning, fireworks, mushrooms, bacteria, algae and many more. The Aequorea Victoria Jellyfish is a jelly that glows in the dark.…
Acinonyx Jubatus Venaticus. Now you must be saying, “Wow, that’s one heck of a name, and what does it mean exactly?”. This is Latin for Cheetah, and the word Acinonyx takes the defining term of “non-retractable claw”. If you are interested in learning more about the marvelous cheetah and all about its lifestyle and everyday activities it partakes in, then I would suggest you keep reading on.…
The life history of the blue crab promotes the widespread dispersal of larvae and consequently high levels of connectivity among estuarine populations. This contrasts with the life histories of many other estuarine invertebrates, with retention of larvae within estuaries and greater self-recruitment. The average lifespan of a blue crab is approximately 3.5 years (Tagatz 1968, Millikin and Williams 1984). Sexually mature females mate once, store this sperm, and use it to fertilize up to 18 clutches (Millikin and Williams 1984, Hines et al. 2003, Dickinson et al. 2006) Each clutch can contain approximately 3.5 million eggs (Hsueh et al. 1993), although egg size, clutch volume, and the success of egg development and hatching decrease over the…
