Mike Hills Aggression in Crayfish: the Influence of Sex on Agonistic Behavior INTRODUCTION All animals employ a vast array of behaviors that contribute to their ability to find resources, increase their chances of utilizing them efficiently, and therefore increase their overall fitness. One of the behaviors observed extensively throughout the animal kingdom to accomplish these tasks is aggression. Agonist conflict and aggressive behavior occurs both between species and within species. Curiously
Imagine you’re in the Deep South, crocodiles, Creole, and the flavor of Cajun America. New Orleans, Louisiana, it’s spring, and it’s time for Mardi Gras. If you want the true Cajun experience, then take a trip down to Broussard’s Cajun Cuisine in Cape Girardeau and they’ll show you what it’s like. Broussard’s Cajun Cuisine has been spicing up Cape Girardeau since 1986. Barron T. Broussard and his wife Kathy moved to Cape Girardeau from Crowley, Louisiana with a plan to bring the Cajun style of Louisiana
Orconectes rusticus, also known as Rusty crayfish, are freshwater benthic omnivores that are important in the lentic ecosystem (Nilsson, E, et al, 2012). Nilsson et al, observed how the Rusty crayfish that are native to the Ohio River valley in North America are dispersing to other lakes and becoming an invader of that ecosystem. Rusty crayfish feed on the microphytes, (Nilsson, E, et al, 2012) which are aquatic plants that enhance water transparency and aquatic biodiversity in fresh water ecosystems
rates than the endotherm. The procedures for this experiment are those that are referred to in Duncan and Townsend, 1996 p9-7. In our experiment however, each student group chose a temperature of either 5 C, 10 C, 15 C, or 20 C. Each group selected a crayfish, and placed it in an erlenmeyer flask filled with distilled water. The flask’s O2 levels had already been measured. the flask was then placed in a water bath of the selected temperature for thirty minutes, and then the O2 levels were measured
“Seeing Through Sound: Dolphins (Tursiops truncatus) Perceive the Spatial Structure of Objects Through Echolocation”, is a research article which explores how dolphins “see” using echoic-visual and visual-echoic matching. They took various structures made out of PVC and presented each to the dolphin either only visual or only by echolocation. Visual-only objects were displayed in the air so echolocation could not be used and echolocation-only objects were place in the box that was echoically invisible
As I walked to school with my lunch that was in a plastic bag. Once we got into school and got in the building my teacher Mr. Williams took attendance and five minutes later we turned around and got on the bus. It was windy and there were leaves blowing all over the place. Last year my 5th grade at John Stewart elementary school was going to Leroy Oakes in St. Charles for team building. It was a fall day and it was chilly. I had my drawstring on my back with my lunch and had three coats on. We
of potassium cannot sufficiently predict the membrane potential. In the experiment however our hypothesis was incorrect, we found no significant between the Nernst-derived equilibrium potential of potassium and the observed membrane voltage within crayfish tail muscle at extracellular potassium concentrations of 10mM, 20mM and 40mM. What this finding tells us is that our manipulation of altering the extracellular potassium concentration cannot be said to have changed the observed membrane voltage.
HISTORY The collective yearnings and expectation of Akwa Ibom people for a State of their own had been long and persistent. Predating the independence of our country, the struggle for geo-political identity for the area and its people had suffered twist and turns along the pathway. But buoyed by the justness of their cause, the people persisted until their erstwhile remote dream became a reality when, on September 23, 1987, Akwa Ibom State came into being as Nigeria’s 21st State out of the former
July 11th, 2001 cold rain poured from the sky, through blurred vision as I struggled to stand up from the damp dirt road, and look at the damage around me, I saw a lone silver car quickly approaching. Have you ever gotten a car with a stranger, without thinking of what the consequences could be? The next thing I remembered I was climbing out of that cramped crowded car, followed by my aunt, three cousins, and two siblings. The moment I looked down to wipe the rocky dirt from my skin, was when I realized
worms, and minnow. If you want a long cast, the nightcrawlers you have must be in the right weight. During the trout's breeding season, the very best bait to utilize would be minnows. But if you wish to catch quite a big trout, you should use crayfish. Worms rigged to gang hooks and left flowing while using current are likely to be considered as all-around bait. During summer, considering they are plenty and to catch, you can utilize grasshoppers and crickets as baits. Trout just adore bugs
Firstly, with Hickory Hollow is the disappearing crayfish in Ribbon Cave. This problem, it seems, is the result of heavy metals found in the water. The heavy metals were found at the site of Ribbon Cave, as well as the northern portion of Aram Creek. We tested for heavy metals at well sites G, I, L, M, and S for heavy metals, with the only positives being well sites I and L. Nevertheless, this still confirmed our theory. The heavy metals found in the water have most likely resulted from Compara Corp’s
Metabolism is a wide subject. It is defined as the summation of all chemical reactions taking place in living organisms. There are many metabolic reactions, however, each reaction has its own importance. Therefore, living organisms need the incorporation of all independent reactions in order to strictly control various metabolic pathways and reactions. When living organisms metabolize food (carbohydrates and fats), almost half percent of the energy contained in these foods is rapidly lost to the
Sofonisba Anguissola was born in the bustling city of Cremona, Italy. She was the eldest of seven children, only one of whom was a boy. Both her parents were of noble blood, her father Amilcare Anguissola, and her mother Biance Ponzone. Her name was derived from a Carthaginian princess which stands for, “exceedingly beautiful and notable”. At a very young age, Sofonisba was pushed to her explore her artistic abilities. She showed her skills through bold uses of identity, she shadowed and studied
everyday looking for something to do, whereas these days I spend my summers looking for ways to get out of doing what I am supposed to do. We would go to the local elementary and middle schools where there was a small creek and pond. We would catch crayfish, bugs, and frogs only to let them go after we celebrated our great achievement. We would play tag, football, soccer, hockey and baseball at someone’s house or at the athletic fields of the schools. And all of us were of the same culture and class
Taxonomic Classification Paragonimus westermani (P. westermani) is part of the phylum Platyhelminthes. Platyhelminthes are flatworms, and are characterized by being acoelomate, triploblastic, and having a simple bilateral symmetry (Berkley.edu). The P. westermani is a member of the Trematoda class. Trematodas are flukes (parasite flatworms) that live inside vertebrates as their primary hosts and inside mollusks as intermediate hosts (wikipedia.org-trematoda). The parasite’s order is Plagiochiformes
farmed. Their history was an interesting time. The religion of the Mandan was similar to many Native American tribes at the time. The Mandan ate the animals and crops that were around them. They ate animals such as deer, elk, bear, antelope, mussel, crayfish, and the seasonal Bison. Their society was, “centred on raising corn (maize), beans, pumpkins, sunflowers, and tobacco, and on hunting buffalo, fishing, and trading with nomadic Plains tribes” (Source C). Some of the Mandan’s food crop would be sold
The wet prairie, or wet marshes, are ecosystems that have standing water for more than 5 months a year. The soil is a thin layer that is soggy when wet and sandy when dry. The wet marshes, when flooded, become home for small fish, tadpoles and crayfish. This then attracts lots of birds, like egrets, herons, wood storks, ibis and dozens more. With all the extra water, plants can grow faster. This brings deer and small animals to the wet land area to forge. The watering hole, is a
Does it matter whether a seemingly obscure language spoken by a few people in an isolated corner of the world goes out of existence? The last speaker died, is how the story began. Not long ago, after having an epic battle with the Bokmal, the Nynorsk was sent to the infinite oblivion. Norwegian population preferred to adapt the Bokmal to their modern lifestyle. Throughout history, languages have been victimized by malevolous political, social and economic forces. These dominant factors can reach
Ricky Swallow is an Australian artist, born in the year 1974 and is currentaly the age of 44. From earlier on, most of his art works refered to pop culture, such as, star wars, the planet of the apes, BMA bikes or DJ culture. But its shown that he’s evolved away from this, with the new aim to 'trap time on the surfaces of his sculptures'; ‘Killing time’ being one piece which showcases this as Swallow delves into his past, to create one of his most perosnal works yet. Momentos, 'an object kept
