Ecology and the Environment

I recently watched a YouTube video documentary called "Jellyfish Invading Japan". Jellyfish thrive in dead zones that result from pollution, over-fishing, or climate change, and the jellyfish out-compete the natural fish populations. However, a chef discovered ways to cook the toxic nomura jellyfish. I wonder whether our jellyfish problem might solve world hunger.

Before I explain my point I just wanted to get some feedback on whether or not i am in the right place doing the right thing. This is the first post I have made on these forums and i just wanted to make sure that i am doing everything correct. According to a carbon dioxide quantity estimate over 1.4 billion years ago there was 10 to 10,000 times as much carbon dioxide in the atmosphere as there is today. In the 1880's Humans had the nice little idea to burn oil and coal to create energy for our cars and houses and lights and Cd players and air conditioners, and before that our planet was steadily losing its carbon dioxide to the ground. My question is, if we never ca…

I had this idea years ago, and I know I'm not the first. Most of the planet is ocean, and most of the ocean is desert. That's because the nutrients sink to the ocean floor, and the surface water is too pure for algae to grow. So all of the Sun's energy goes nowhere, it just warms the water. There have been trials of seeding the ocean with finely ground iron, or iron ore, not sure which, plus other similar trials, and it did result in a temporary algal bloom, but the effect is soon lost, as the stuff sinks out. My idea is a sunken flat plastic sheet, kept at such a depth that the waves and UV don't damage it, trapping the surface layer of water. To get nutrients…

Hi. A SHAME : And it is not the first time I see this. They are capturing babies, well under reproduction age, leaving no hope to future populations . With a third of contents being cheap oil. Remember when there were two to three tightly packed. Like 15 now. [Product of Poland]

Do you feel adding self storage facilities in the zoos can be useful to the general public or visitors? For example : ZSL, London. Thanks & Regards, Prashant S Akerkar

Hello, everyone! I would be very grateful if you could help me find an answer to my question. Since in nature, everything is connected to everything I can imagine that one requires tremendous amounts of data for the research to see how much individual events may affect the changes in populations, habitats or biomes. I know there is ILTER, who connected several institutions into a network that is generating statistics across multiple countries but they are present only in 40 countries if I am not mistaken. And even if there is enough data, then there might be problems related to storage or searching for the right information. Just where these limitations lie…

https://phys.org/news/2018-07-universal-plastic-tragedy.html Twenty five years ago, I spent a summer removing plastic packing bands and plastic nets from 135 entangled Antarctic fur seals on Bird Island, South Georgia in the sub-Antarctic. Plastic marine waste discarded by the fishing industry were the primary source of entanglements. A quarter of a century later, plastic is still a huge problem. In the past month alone, we have seen dead whales wash ashore with their stomachs full of plastic bags. This ought to be a strong enough signal to trigger collective action to clean up and improve governance of the plastics that have become this century's Tragedy o…

So, if you build a latrine...just a hole in the ground and add excrement to it, it smells, harbors pathogens and doesnt really get converted into anything. Compost toilets on the other hand, have little to no smell, has no pathogenic bacteria and the waste is converted into compost. I was wondering if compost toilets work as opposed to latrines because when you add extra carbon materials (i.e sawdust) and oxygen it allows for growth of thermophilic bacteria. Thermophilic bacteria raise the temp of the waste and kill off the pathogenic species. So in this case, are compost toilets akin to where the desired bacteria are selected via conditions of…

Can decomposition take place in the absence of bacteria? If sterilized organic material were in a sterile environment (with moisture) would it last forever?

Hi everyone! We'd like to present a natural, eco-friendly, quiet and smooth alternative to aerial monitoring of ecosystems: a kite. We did a quick (and rather unscientific) test of kite aerial monitoring of a fragile habitat under invasion: Natura 2000 protected marsh of Radensko polje, Slovenia. Aerial photos cah help in assesing the number of invasive plants in an ecosystem. Kite aerial photos even more so, as the kite is way eco friendly than other alternatives ... you just don't go buzzing above an important habitat scaring the hell out of everyone (especially them protected species)! url deleted Thanks and have a nice day!

Good Day, Thank you for taking the time to read this thread. My gf is finishing up her masters in Ecology. I've been in the canadian military for almost 9 years now. She's excited to start working after her thesis defense later this year. I come from a military family so how environmental jobs I don't have a lot of information on how it works. We both don't really know a lot about how a career in the environment will work with my military career in the army, as I sometimes have to move and I'm limited as to where I can go. Are there environmental jobs that can move or can be transferred to other parts of the country? I've had little luck trying to find answers on the…

It is claimed that solar cell efficiency record achieved 32.6% under one -sun. https://en.wikipedia.org/wiki/Solar_cell Would it be possible to achieve the same efficiency someday, for living plants with help of gene engineering? If yes, how much would it change our civilization? For example, prices for food, wood and biofuel? Would it become cost efficient base all energy production on biomass burning?

Hi, in school, since i study biology, a lot of ppl are pro environment. I recently decided to become vegetarian too, and quickly I realised a lot of ppl in my degree were convinced it would be worse if everyone was vegetarian, partly due to monocultures, and the fact that a lot of livestock would still be needed for cheese, eggs, ... And vegan would be worse due to a huge amount of monocultures. I believed livestocks were fed from monocultures too, and therefore a bigger amount of cultures were dedicated to livestocks over human consumption. Do you guys have any good source with stats on how many monocultures there are today, and percentage dedicated to us vs livestocks? …

Hey guys! I need help in identifying a colony that has developed on my home made electrode. I have been experimenting with simple microbiological fuel cells and its been pretty interesting! I've torn apart my previous experiment and found something that wasn't there before. I've tried to search the internet for clues and so far I have convinced myself that it is most likely a bacteria if anything else. Unfortunately as this is a little home experiment i don't have the means of obtaining a microscopic image and this is all I can give to work with. Look forward to your replies! PS: The black matter is simply activated carbon powder attached to a steel mesh. The …

In another thread, we discuss the condensation of water from a humidifier. I think my question is too much off topic, so I created a new thread. The main question is: What's the point of a humidifier? I never understood the problem with humidity actually. After all, people live from the deserts to the rain forests, and it's not like there are certain areas in the world where everybody is sick. It's perfectly normal to live in a country with 75-100% humidity most of the time (e.g. the Netherlands), or in countries where it is quite dry. Here's a map of the world showing relative humidity. Because I live in the Netherlands, which is naturally wet, I have never…

Hi! I'm currently a Ph.D. student in Utah. My project involves a lot of seeds to look at the seed and seedling preferences of rodent communities in burned vs unburned areas of the Great Basin a Mojave deserts. I'm halfway done with my data collection, however, I am starting to run low on some seeds, particularly invasive seeds that can't be bought, and other hard to find seeds. If anyone knows of any way I can get more of the following seeds, I will be very grateful: Great Basin seeds Halogeton Gloneratus Ceratocephala testiculata - Burr Buttercup Alysium allysoides Elymus elymoides - Squirreltail Mojave Desert Seeds Bromus tectorum - Cheatgrass…

hello guys! please i need your help to get answers to this survey! it takes between 5 to 10 minutes only!! pleaaase it's for my studies!! thank youuu!!

Hello everyone, I often felt sorry for those millions animals being horribly killed. I prayed and a very original answer arrived. A solution that I hope scientifically possible to finally leave these poor animals in peace. Does the solution that follows seem scientifically serious to stop eating meat and stay healthy?

• I am about working on the Final effluent of a Waste water treatment plant. I will be collecting samples for a period of 12 months; 1 (one) sample per month. Sample collections will be split between autumn, winter, summer and spring. The physiochemical parameters like Temperature, pH, Electrical conductivity (EC), Turbidity, total dissolved oxygen (TDS) and dissolved oxygen (DO) will be taken along with the microbiological components like bacteria (Feacal coliform , E.coli and Vibrio) and viruses (Enteri virus, Rotavirus, Norovirus and Adenovirus)will also be looked into. The whole data collected is to access the quality of the final effluent wastewater and …

If there is any Latest news about Food Webs? I am a man who need some new details about Food chain.

I'm setting up an experiment and would like to be able to monitory it from a distance using a HD video feed that I can check online. Can someone please recommend a system for that please? Is there some sort of kit that includes a video camera and sensors (temp, humidity...)? Thank you for your help.

Question 1:Is it factually incorrect to say homosexual acts can be seen in many species? Question 2: Also even if that were true it wouldn’t matter humans have sex/procreate by choice & for pleasure other species by instinct it’s apples & oranges.What do you think?

I have to isolate the bacteria for a school lab project. I obtained river water and soil next to the river, then streaked both on an agar plate but no P.aeruginosa growth was seen. Research I've done suggests that it grows on wounds and in hospitals, but those are not at my disposal. My professor said I may find some on rotten vegetables. Is this true? Any lab techs, former micro students, or micro savvy people have any suggestions of where I can easily find it? TIA! (:
