Habitat structural complexity can strongly affect biotic interactions. Typically the more complex the habitat structurally reduces predator efficiency. predation is significant source of mortality for tadpoles. Many predators are gape limited rapid growth in size important, same time the tadpoles need for food to get big exposes them. So anything that can not get them killed but also allow feeding is important. Because of the complexity of habitats can reduce predation rate but also encourage more foraging. Numerically dominant in ephemeral sites which breed active foragers when in presence of insect predators. Squirrel tree frogs did not decrease activity in the presence of predators 129 rather the cover and complex structural environment reduced the ability for the predator to visualize the prey and stalk it. also rapid drying of the ponds make dying from drought a more significant threat to the frog

non native catfish did not seem to prey anymore then the native species of predatory fish did in fact it had significantly less success more likely due to foraging behavior resulting in less prey- predator encounters this is in temporary wetlands. Eastern mosquitofish native still killed more so they think that the non native species did not significantly alter population assemblage.

Cuban tree frogs compete for habitat with native species and eat native frogs and lizards, Johnson said.

Of particular importance, our study quantifies the

mechanisms   by   which   native   anuran   larvae   are impacted by the presence of the exotic O.

septentri- onalis. Unlike the decline of adult native anurans due largely  to  predation  (Meshaka 

2001),  the  decreased survivorship among native larvae is not the result of predation  by  O. 

septentrionalis.  Instead,  O.  septen- trionalis out-competes native tadpoles then scavenges dead

individuals. Native larvae are also scavenged by conspecifics,   the   added   mortality  

experienced   in mixed-species  assemblages  relative  to  native-only ponds is a strong indication

that intense interspecific competition, followed by scavenging, leads to a sharp decline   in  

native   species   survivorship.   The   pro- nounced  decline  in  survival  observed  among 

native tadpoles  supports  the  predictions  of  Smith  (2005), who indicated that the presence of

O. septentrionalis larvae  during  the  entire  larval  period  could  signifi-

cantly impact native survival.

N. Feeding Behavior. Squirrel treefrogs are aggressive predators that feed on insects and other invertebrates (Wright, 1932; Garrett and Barker, 1987). Carr (1940a) noted that they are "Often present in enormous numbers along lake-shores when chironomids (Diptera) are emerging; they also collect around lamp posts and lighted windows at night. I once saw nine young in a circle around a pile of newly deposited cow-dung, awaiting and devouring the midges attracted thereto." Duellman and Schwartz (1958) examined the stomachs of 20 individuals and found that 9 were empty, 2 contained only plant debris, and 4 contained beetles (Coleoptera); other stomachs contained crustacean (crayfish?) remains, a spider (Arachnida), a cricket (Orthoptera), and an ant (Hymenoptera). Brugger (1984) found that two groups of arthropods (Arachnida, Isoptera) and three orders of insects (Coleoptera, Orthoptera, Hymenoptera) dominated the diet of frogs from northern Florida. Goin and Goin (1957) noted that differences in habitats selected by adults and juveniles may result in dietary differences.

O. Predators. Duellman and Schwartz (1958) observed ribbon snakes (Thamnophis sauritus) feeding on squirrel treefrogs. Other predators undoubtedly include small mammals, birds, other frogs, other snakes, and aquatic invertebrates. Dragonfly naiads and water bugs (Lethocerus) eat tadpoles (Babbitt and Tanner, 1997).

P. Anti-Predator Mechanisms. Their small size, propensity for seeking small hiding places, and ability to change colors to match their background probably aid in avoiding visual predators.

Species  introduced  outside  their  native

range  to  serve  anthropogenic  purposes  may  have unintended consequences on native organisms.

Mos- quitofish (Gambusia affinis and Gambusia holbrooki) have been introduced throughout the world

to control larval mosquito populations in aquatic environments, but they have also been implicated

in the decline of native fish, amphibian, and aquatic invertebrate pop- ulations.  We  investigated

 the  roles  of  introduced western  mosquitofish  (G.  affinis),  and  two  naturally colonizing

predators (crayfish and dragonfly naiads) in inflicting tail injuries observed on ranid frog

tadpoles in experimental constructed wetlands. We also exam- ined the influence of vegetation in

reducing tail injury severity.  We  found  that  mosquitofish  significantly increased the

prevalence and severity of tail injuries, but  crayfish  and  dragonfly  naiads  contributed  much

less to increased injury levels. Furthermore, increased

vegetation  cover  did  not  significantly  attenuate  tail

injuries. However, after chemical removal of Gambu- sia,  injury  prevalence  and  severity  was 

significantly reduced. Although previous investigations have con- cluded that mosquitofish prey

upon the eggs and larvae of  some  amphibians,  our  results  illustrate  that  these fish  can 

cause  substantial  but  apparently  sub-lethal injuries  to  large  numbers  of  larval 

amphibians  in  a wetland.  Further  investigations  are  needed  to  deter- mine if these injuries

impede the fitness of victims and

lead to population reduction

Rough Draft:

As tadpoles the Squirrel Tree Frog is preyed upon by dragonfly nymphs, anax pachy, diplay tramea, giant water bugs, predatory fish and newts^{[1] [2]}. Once the frogs become juveniles and then eventually adults the predators of the frogs change to small mammals, other frogs, snakes, birds ^[1].

Once the Tree frog reaches its juvenile stage it starts to feed on arthropods, flies, beetles, pill bugs and spiders^[1]. Additionally according to Dodd they can consume arboreal insects and small crayfish.

In order to reduce the danger of being eaten as tadpoles they use dense vegetation as cover ^[3]. However they do not seem to reduce activity within this cover. Babbit seems to think that drying of the ponds is a more significant threat to the frogs. As adults they use their diminutive size and color changing ability^[4].  The frog also tends to hide in a retreat during downtime along with repressed activity. Feeds within 28 meters of this retreat site^[1].
