	abstract = {Abstract\&nbsp;\&nbsp;The composition and temporal changes of edaphic microarthropods in both litter layer and soil were analyzed in a tropical dry forest ecosystem in Western Mexico. Sampling was carried out from June 1991 to July 1992 in two small watersheds at the Chamela Biological Station (Jalisco State, Mexico). At each watershed 10 random cores samples, 11\&nbsp;cm in diameter and 5\&nbsp;cm depth, were taken monthly from each biotope from an area of 100\&nbsp;m2. Fauna was extracted by Berlese-Tullgren funnels and preserved in 75\% ethanol. The total abundance of arthropods was 96,338 specimens, belonging to 33 taxa. Numerically dominant groups were Prostigmata, Cryptostigmata, Collembola and Mesostigmata, which constituted 92.6\% of the total abundance. The effect of current monthly precipitation and temperature on density of total Arthropoda and different Orders was also investigated. Precipitation and temperature were significantly correlated with Collembola and Mesostigmata densities and also with total arthropod. The seasonal variation in the amount of litterfall was also significantly related to the abundance of arthropod in the litter layer biotope.},

	abstract = {Litter frogs at two rainforest locations in Panam{\'a} elect prey in a pattern similar to that found for litter frogs in lowland Per{\'u} (Toft, 1980) despite differences in the frog fauna between Panam{\'a} and Per{\'u}. Species of litter frogs form a continuum from species that specialize on ants and mites, through generalists, to species that avoid ants and mites. Modes of foraging and predator defense and taxa of litter frogs are correlated with position along the continuum. Atelopus and Bufo (Bufonidae) and Dendrobates (Dendrobatidae) are poisonous, searching foragers which eat many small prey, primarily ants and mites, per day. Colostethus (Dendrobatidae) eat ants, but to a lesser degree, and have a more sedentary foraging behavior than Dendrobates. Eleutherodactylus (Leptodactylidae) are cryptic, sit-and-wait foragers which eat few large prey per day, with the exception of E. vocator, which eat ants in proportion similar to Colostethus. Evidence within the Dendrobatidae suggests that specialization on ants is derived from a generalized mode of foraging. Ecological correlates of foraging mode in litter anurans are summarized and are generally similar to those in desert lizards.},
