Kin recognition and cannibalism in spadefoot toad tadpoles
Article Abstract:
Spadefoot toad tadpoles can be either carnivorous or herbivorous, and this affects whether they associate with kin, and cannibalistic tendencies. Laboratory tests indicate that omnivores tend to associate with kin, and carnivores with non-kin. Carnivores also tended to eat kin when hungry, though when less hungry, would release conspecifics if they were kin, and eat non-kin. Kin recognition appears to allow carnivores to feed without killing their siblings, while omnivores appear to seek advantanges from staying near the site where they hatched.

Yellow-bellied marmot and golden-mantled ground squirrel responses to heterospecific alarm calls
Article Abstract:
A study was conducted to examine the reactions of the yellow-bellied marmots, Marmota flaviventris, and golden-mantled ground squirrels, Spermophilus lateralis, to alarm calls to test whether interspecific call recognition occurs in sympatric species that rarely interact. A repeated-measures design was utilized in the playback experiments. The squirrels and marmots were characterized by a similar range of anti-predator conduct when responding to either natural calls or predators.

Nepotism and marmot alarm calling
Article Abstract:
Three issues in the research by Daniel T. Blumstein and Kenneth B. Armitage regarding the alarm calling of yellow-bellied marmots, Marmota flaviventris, are problematical. The first concerns the feasibility of their conclusions. The second concerns their use of the simple weighted sum to calculate inclusive fitness. The last concerns their finding that the primary function of alarm calling by yellow-bellied marmots is care of vulnerable offspring.
