What do we know about its distribution and habitat needs?
To conduct their experiment, the researchers collected L. peronii eggs from a natural stream. After the eggs had hatched, tadpoles were raised in artificially constructed 2 L containers in a laboratory. All containers were filled with 1 L of filtered tap water, and the water was changed every other day. Thirteen tadpoles were placed in each container, and the tadpoles were exposed to a 12-hour light: 12-hour dark photoperiod. All tadpoles were fed thawed spinach daily.
The researchers randomly placed the tadpoles into containers exposed to one of four treatments, with nine replicates of each treatment, as follows:
Low UVBR (<6.0 kJ/m2), low temperature (15OC)
Low UVBR (<6.0 kJ/m2), high temperature (26OC)
High UVBR (>70.0 kJ/m2), low temperature (15OC)
High UVBR (>70.0 kJ/m2), high temperature (26OC)
The researchers recorded the number of tadpoles still alive out of the original 13 in a container (percent survival) at different time periods. Their results at Week 4,…

These results provide further evidence for the effects of habitat size on the phorid-Acromyrmex system in a tropical rain forest, based on the abundance of parasitoids both as adults in the field and as reared immature phorids in the laboratory. Phorid parasitized leafcutter ants were most abundant in areas of continuous forest, and less abundant in the forest fragments. O Phorid flies are important parasitoids of leafcutter ants nd leafcutter ants can be found in Brazil's Southeastern Both phorid flies Atlantic Forest. The study provides evidence that this parasitoid-host interaction between phorid flies and leafcutter ant differs between continuous forest and forest fragments. Phorid flies were just as abundant in forest fragments as they were in continuous forest, but were less successful in parasitizing leafcutter ants.arrow_forward
