Nobody likes a mooch, but new research finds that grifting off others is a sound evolutionary strategy. Parasitism — a survival strategy that involves hijacking a host's nutrients for one's own ...

Behavioral Ecology and Sociobiology, Vol. 19, No. 3 (1986), pp. 221-232 (12 pages) During a two year study of the moorhen, Gallinula chloropus, a quarter of the nests found had two or more females ...

Behavior in eusocial insects likely reflects a long history of selection imposed by parasites and pathogens because the conditions of group living often favor the transmission of infection among ...

Today, 150 years after Darwin’s epochal “On the Origin of Species,” many questions about the molecular basis of evolution are still waiting for answers. How are signaling pathways changed by genes and ...

HYDERABAD: A genomic study by CSIR-Centre for Cellular and Molecular Biology (CCMB) and Indian Institute of Science Education ...

Molecular biologists have decoded the genome of the Pristionchus pacificus nematode, thereby gaining insight into the evolution of parasitism. They have shown that the genome of the nematode consists ...

One of the most interesting topics discussed in my Ornithology class was about the “con artists” found in nature… Brood parasitism occurs when a female bird (the parasite) lays her eggs in the nest of ...

The blood fluke may be the ultimate parasite. This ingenious flatworm comes of age inside a tiny snail host before entering its real host—humans—directly through the skin and burrowing into the ...

IN these lectures the late Prof. Theobald Smith reviewed the knowledge and experience of nearly fifty years of fruitful devotion to research on infective disease in man and animals. The book contains ...

Brood parasitism among females of the same species is common in certain fishes, insects, and birds, including coots. Host parents bear a high reproductive cost when raising chicks that are not their ...
