It was shown that the cardiac tissues of tadpoles differ from those of frogs by their antigenic properties (particularly as a result of the presence of the antigens in tadpoles, which are absent in the adult frogs, i.e. of the stage-specific antigens). Cardiac tissues of tadpoles are ...
The researchers say this shows how sharing data between surveys with different aims can lead to new discoveries-even about species that experts believe they know well. Through the discoveries the researchers also have a clear understanding of how important tree hollows, cracks and holes are to a...
In response to the sperm from another species male, it is a typical unisexual reproduction mode of gynogenesis, in which only female nucleus develops to enter the first cleavage6,8. In response to the sperm from different clone male, the currently observed unusual chromosome behaviors including ...
These different sperms include the sperm from the same clone male (A–F), the sperm from the different clone male (A'–F') and the sperm from male of another species Cyprinus carpio (A''–F''). The corresponding time (min) is shown on the right corner. Thin arrows indicate the rep...
aThere are two treefrogs considered "sibling species". One is a diploid (normal) form; the other is a tetraploid, with four sets of chromosomes, rather than two. The only other way to tell tham apart is by the call. If you have preserved specimens and cannot karyotype them, you cannot...
A species of mollusc living in the Antarctic surprises scientists with its ability to switch sex in order to reproduce efficiently in extremely cold conditions. Posted in Thought of the day | Tagged antarctic, mollusc, scientists | Leave a reply Studying Ants Antics ? What a waste of time an...
Flies (Diptera) have played a prominent role in human history, and several fly species are reared at different scales and for different beneficial purposes worldwide. Here, we review the historical importance of fly rearing as a foundation for insect rearing science and technology and synthesize in...
As a journalist, sometimes you have to face your fears to tell a story. Having had a phobia of snakes my whole life, the last thing I ever thought I’d do was report on a species I am the most scared of. But should snakes really be this feared? I faced my nightmare, learnin...
the amount of helplessness and stupidity prevalent amongst your species is, and has always been, pandemically crippling for you when left without alien help. The truest testament to this is, as I hinted at earlier, a belief many of you have that you are alone in the universe and that you...
