“…In ephemeral resources, it is common to find these species in the process of intraguild competition, particularly when resources are scarce (Revilla 2002;Duarte et al 2013). Muscidae species that occurred in this study exhibited this behavior.…”

“…Larvae of Muscina are facultative carnivores. Thus, despite their potential as vectors of pathogens in the adult stage, in the larval stage they can effectively limit the abundance of other dipteran species by preying on their immatures (Duarte et al, 2013). The medical and veterinary importance of Muscina spp.…”

Three representatives of the muscid genus Muscina Robineau-Desvoidy (Diptera: Musicidae), Muscina levida (Harris), Muscina prolapsa (Harris) and Muscina stabulans (Fallén), are well known for their medical, veterinary and forensic importance. However, data in the literature provide contradictory information for the identification of third instar larvae of these species. This hinders easy species differentiation because it requires the rearing of material to adult stages in order to facilitate reliable identification. Third instar larvae of these three Muscina species were studied in detail using light and scanning electron microscopy to provide thorough redescriptions of their morphology. Existing information concerning third instar morphology, with particular reference to its value for taxonomy and identification, is revised and discussed. Emden's spiracular distance factor (SDF) is considered here as inappropriate for identification purposes in third instar larvae of Muscina spp. because its values are not constant ratios but increase during larval maturation and overlap in the examined species. These species were, instead, discriminated here by differences in the spinulation patterns of their abdominal segments.

No evidence of nonlinear effects of predator density, refuge availability, or body size of prey on prey mortality rates

Predator density, refuge availability, and body size of prey can all affect the mortality rate of prey. We assume that more predators will lead to an increase in prey mortality rate, but behavioral interactions between predators and prey, and availability of refuge, may lead to nonlinear effects of increased number of predators on prey mortality rates. We tested for nonlinear effects in prey mortality rates in a mesocosm experiment with different size classes of western mosquitofish (Gambusia affinis) as the prey, different numbers of green sunfish (Lepomis cyanellus) as the predators, and different levels of refuge. Predator number and size class of prey, but not refuge availability, had significant effects on the mortality rate of prey. Change in mortality rate of prey was linear and equal across the range of predator numbers. Each new predator increased the mortality rate by about 10% overall, and mortality rates were higher for smaller size classes. Predator–prey interactions at the individual level may not scale up to create nonlinearity in prey mortality rates with increasing predator density at the population level.
