Topic: what are the common habitats of mosses?
Replies: 4

Mosses are avascular pioneer plants. So they are able to survive even in the harshest of environmental conditions (climatic, shading and soil wise). They tend to prefer acidic soil or substrates to basic ones. One doesn't only find mosses on damp places but also on sites which are very much exposed ...

You can of course also contribute a great deal to general entomological knowledge by "just" observing insects and not collecting them. This would then contribute to the knowledge on the aut- or synecology of those selected species. At one point however, you also have to refer to an entomol...

It is very laudable to care about our environment and to do something about it. Now, as a physician, in order to become a biologist/ecologist, you still would have to study on for a couple of years. When finishing your studies, it will still not be sure to receive a job in that field of animal behav...

An ecological niche is the role an organism plays in a community in terms of the habitat it occupies, e.g., both a wolf and the wolf spider are predators. So they occupy the same ecological niche, albeit in a different habitat (even though they can live together in the same area, the habitat of the ...

It is really hard to see..
Was that "insect" still moving? Did it move away after you took that picture?
If not, it might look like the cast, old exoskeleton of some insect with indirect metamorphosis, perhaps a large cicada?

If it's not too late already for your assignment, very briefly: prokaryotic cells are in general much smaller than eukaryotic ones, they have no membrane-bound organelles, and the only organelles they have are ribosomes (which are also smaller than the ones in eukaryotes). Prokaryotes are generally ...

Re: Is there an insect that behaves this way?

Hi "sushiboy", sure there are insects that do this. These are the "fireflies". However, they are not flies but beetles of the family Lampyridae. And both the males and the females produce "cold light" (by transforming the energy of some of their body-fat via special enz...
