Ecology and the Environment

I am a year 12 student studying the SACE subject Research Project. I currently attend Saint Ignatius College in Australia. The research project allows students to undertake research in their area of interest and then present a research outcome, the topic I have chosen to research is over fishing. The survey is only 9 questions (multiple choice) all repsonses are greatly appreciated. http://www.surveymonkey.com/s/Y3NJBMG If you have any personal knowledge on the topic, it will be a great help if you shared it with me. Thanks everyone

So far I planted: Ipomoea aquatica also known as Chinese Spinach and Kangkong Sweet basil (don't know the Scientific name for it) Scallions Thymes Myrica pensylvanica also known as bayberry and a few more herbs like oregano anyways I would like to ask for suggestions on what to plant next beside the herbs stated above, it would be appreciated if anyone would share their favorite herb.

Planet Earth has 30% oxygen, all of that oxygen comes from plants. So if we take some (frozen)samples from Neptune and heated the water down could be drinkable Here on earth? Planet Neptune is mainly Hydrogen which sits at 80% but there are small traces of both Helium 18% and Methane 1.5% (Both are gas) (Theory) Could it be possible, that if we were to loose our drinking supply here on earth. We could take chunks of ice from Neptune and and make it drinkable here on earth? Maybe, I was looking at some articles where some guy was explaining exactly what helium does to the body. It cuts off oxygen supply but , earth has plenty of oxygen to make up for the damage of …

Is feedback negative when AB < 0 or when 1/(1 - AB) < 1? And, correspondingly, is feedback positive when AB > 0, or when 1/(1 - AB) > 1? I've found nothing but conflicting information on this. Also, while species, the regulation of hormones, nutrients, and even entire populations are governed via negative feedback, how does one determine what A and B are? In a furnace, for example, governed via a traditional thermostat, this is clearly a negative-feedback system. But what is A in this case, what is B, and which equation quantifies it as a negative-feedback system? AB < 0? Or 1/(1 - AB) < 1?

When I was thinking about sexuality as an adaptation, I wondered whether excessive tendencies toward heterosexuality could be maladaptive, especially for species that put a great amount of nurturance into their offspring. If a female mammal is producing too many offspring, she'll probably invest less into each offspring. At what point does this become maladaptive? If it becomes maladaptive, she might stop caring for some of the offspring, but that doesn't undo the initial investment during pregnancy. Anyway, the two main explanations for genetic male homosexuality seem to be: the kin-selection explanation—homosexual men help care for related offspring the sexua…

While undertaking a small piece of research within the confines of the Earth Science Forum , I have been exploring the history of Calcium from Space Nebula to the White Cliffs of Dover. I hit a tricky bit when I was investigating how very early forms of Bacterial, Planktonic, Algae or other Precambrian forms of life obtained calcium from the actual presence of various calcium compounds found in the Oceans and Earths crust, particularly, but not necessarily only , within the period 4,500 MA to 550 MA ( MA Million years ago ). In their wisdom , one of the advisors suggested I try the " Biology " forum. So here I am , asking the question. . By what mech…

I was designing the atmosphere of the homeworld of a species that is used to has lungs that make use of both oxygen and nitrogen, but for different things... They breath like us but also benefit from nitrogen (they can survive between 5 months and less than 4 years in our atmosphere but with ngeative consequences after 5 months or so of not breathing nitrogen) and this meant they had to have much more nitrogen in their atmosphere which meant I had to sacrifice oxygen because argon and carbon dioxide are almost non-existent and since carbon dioxed is a waste product of breathing oxygen and being carbon based I replaced argon with an unspecified nitrogen compound I called "…

Do plants emit different gas types depending on whether or not they are healthy? or in need of fertilizer? I'm trying to figure out a quick way to measure plant health using chemical gas sensors, any input on plant biology would be appreciated! Cheers.

I was writing an essay today about ecology, and realised that I didn't actually know what it meant. What sort of areas of science does is cover? Is classification of organisms included?

This might sound a little odd, but I need to interview someone who is in the environmental science field. I am taking a human development class for career exploration, and I need to interview someone that is in the field of work that I am interested in. The person that I had lined up cancelled on me today, and it is too short notice to get a hold of anyone else in my area. My paper is due this Friday. I've looked around online and I'm hopeful that someone in this community would be able to give me some of their time. I'm not sure what specific field I want to go into, but so far I've come up with Park Ranger (or something along those lines) or working for Fish an…

I am taking an ecology course and we decide an experiment on the accuracy of using a quadrat to measure the population density in uniform, random and clumped distribution pattern. We found the accuracy is not that good when using quadrat to measure the population density of clumped and random distribution pattern. I can't figure out why the accuracy is lower in these 2 distributions and how to obtain a more accurate measurement in these 2 distributions.

I understand Symbiosis is two creatures of some sort living off each other in a way the benefits them both, and is overall keeping their species stable. My question is, does anyone have any good examples of this? Or ideas of good articles? I need information for a test, and I don't want to have to sift through misleading google searches Thanks in advance. Correction. I didn't mean to put the section "benefits them both", only mutualistically. Stability also isn't guaranteed. Question still stands

Hi. Is the exhalation of CO2 by plants in periods of darkness -as night time- a necessary biological process for their proper growth, or are unaffected growing better/more with full time natural + artificial illumination ?

Dear Friends, We are facing difficulties while maintaining cooling towers by rapid growth of Algae. This spoils water content in it. I am really not sure but it may tend to increase hardness of water. Blowing down process is not effective due to this case. We can not add any acid forms because the thin copper valves are located inside the tower. Once I tried coppersulphate but it increased the hardness value. So I am seeking permanent chemical, physical or biological solution which does not have any side effect to other parts of this.

Hi, I am a Grade 11 Student (CBSE) from India and some questions popped up in my mind. Would be glad if you could help me out! What is the exact beginning of life? Who provided the force needed to create this massive universe, the supernovas and the Earth ? Who provided the angular velocity for earth to rotate and revolve? Does the universe continuously expand? Should the definition of 'Living Things' be redefined to objects or substances or phenomenon that possess Kinetic Energy? Lots of external factors influence life tremendously and these things have complete control over our life - Pressure,Air,etc.

Hi there, So in recent years, biology and especially ecology, has taken a more quantitative approach to answering questions. The Janus Effect is a phenomenon that scientists sometimes employ to draw broad-scale conclusions that are out of the focus of a small-scale study. For example, finding a biochemical/genetic effect of a substance on an organism does not necessarily cause a population/ecosystem-level response. Nonetheless, it is important to work step-wise up the ladder of organisation and determine these broad-scale effects. How far do you think it is plausible/acceptable to extrapolate results from a regional quantitative landscape ecology to draw concl…

Hi there, What do you think some of the knock-on effects of climate change are on biodiversity of volant mammals? Feel free to post, I look forward to synthesising your ideas!

Hi there, So these days, it seems pretty easy to say things like, 'over 7 billion people and counting? I think it's time we put baby tax into play.' But socioeconomics will beg to differ. In the past, it was easier for people to manage their natural resources, but with the population booming, resources are not only dwindling, but running out. How does one begin to justify nature conservation when there are millions of Africans who need water, land for growing crops, houses etc? How does one approach a village of hunger- and poverty-stricken people and ask them to limit their cattle grazing? I was naive to once think that people in rural areas had as many kids as t…

Prevailing winds travel from the west to the east in on all parts of the globe. This is true, say, roughly somewhere 70% to 95% of the time in the global atmosphere. The moon raises/moves billion of gallons of water daily as tidal movement. The same force is likely responsible for the movement -- or non-movement -- relativistically, of the atmosphere because the earth revolves substantially faster than the moon's orbit (regardless of whether it goes forwards or backwards). Solar energy is responsible for some acceleration of particles in the atmosphere on that daily basis, ((the word for this)), but tidal forces are undeniably controlled by primarily by lunar fo…

Successful rescue operation after a broken compass or whatever happened to these porpoises. -----> http://elcomercio.pe/player/1384898

what insect did that? see pictures below What do you think? Note: I don't know the answer.

First, read about this strange creature found in Australian waters: http://ca.news.yahoo.com/world-first-hybrid-shark-found-off-australia-070347608.html Now, after you read the article, I wish to ask this question: If there can be a hybrid Australian Black-Tip/Common Black-Tip, what other hybrid mixes can we have for sharks? Perhaps a Hammerhead Shark with a Great White Shark? What are the evolutionary advantages or disadvantages of the different interbred shark possibilities?

I seem to have searched the whole web, and still couldn't find the name for this crab. Can anyone help?

Biomedical animator Drew Barry states that mosquitoes are normally vegetarians, and only pregnant female mosquitoes drink blood; and only for "special nutrients". Perhaps people could construct "mosquito feeders", that "smelled like animals", and contained said special nutrients, so that the mosquitoes would be attracted to the bait, over actual people ?
