“…It is well accepted that newly created wetlands should be assessed with deep, qualitative and long-term studies (Zedler and Callaway, 1999;Pechmann et al, 2001;Petranka et al, 2003Petranka et al, , 2007Vasconcelos and Calhoun, 2006). However, this study provided evidence of the benefits of artificial MTPs for amphibian conservation already within a short-term period.…”

“…To evaluate how to lessen the effects of wetland loss on amphibian populations, studies have monitored both short-term (e.g., Perry et al, 1996;Lehtinen and Galatowitsch, 2001;Balcombe et al, 2005;Barry et al, 2008) and long-term (e.g., Pechmann et al, 2001;Petranka et al, 2003;Vasconcelos and Calhoun, 2006) colonization patterns and restoration effects. These studies revealed that the timescale of operation for the newly created or restored wetland is critical, as temporal population responses and environmental stressors determine which species are likely to benefit from the wetlands (Petranka et al, 2007).…”

-Mediterranean temporary ponds (MTPs) are crucial breeding sites for local amphibians, a faunal group in decline in the Mediterranean mainly due to wetland destruction. Although the disappearance of lentic habitats in other regions of the world has been ameliorated by the creation and restoration of wetlands, these tactics remain untested in Mediterranean wetlands. To evaluate the amphibian colonization dynamics of artificial MTPs in the north-eastern Iberian Peninsula, we monitored two artificial MTPs (one in a highdiversity area and the other in a low-diversity area) over 2 years. We selected reference wetlands at each area, and amphibian communities of man-made MTPs were compared to those of reference wetlands. We found that, beginning in the first year, artificial MTPs were a valuable habitat for regional amphibian fauna. Posteriorly, we focused on the reproductive success of the natterjack toad, Bufo calamita. Using a drift fence equipped with pit-fall traps, we measured the abundance of both reproductive adults entering the pond and post-metamorphic individuals exiting the pond. Using mark-recapture methods, we analyzed the time and energy costs associated with reproduction in the artificial MTPs. We observed a highly variable colonization dynamics between sites, between hydroperiods, and within hydroperiods, and these dynamics often depended on meteorological factors. Our results suggest that even at a short timescale, native amphibian species such as B. calamita can benefit from wetland creation in the Mediterranean region.

“…Using the number of spawn clumps as an estimator of population size is an accepted method for ranid frogs (Crouch and Patton 2000, Loman 2007, Petranka et al 2007), which produce discrete clutches and spawn once in a year. Drift fence studies for pond breeding ranids show very close correspondence between number of spawn clumps and number of female frogs (Couch and Patton 2000).…”

“…For example, morbidity and mortality of turtles due to ranavirus may be often missed given the secretive nature of these animals (Farnsworth and Seigel 2013 ). However, many ranavirus outbreaks that fi t the general pattern of rapid onset of mortality in the summer have been observed in well-studied, frequently visited populations (e.g., Brunner et al 2011 ;Langdon and Humphrey 1987 ;Petranka et al 2007 ;Wheelwright et al 2014 ), suggesting that detection biases are not a general explanation for the observed timing of mortality events.…”

“…Petranka et al ( 2003Petranka et al ( , 2007, for instance, reported minimal recruitment of wood frogs at several newly constructed wetlands over an 8-year period due to annual die-offs from ranaviral disease. Recently, Earl and Gray ( 2014 ) used a matrix population-projection model to demonstrate that local extirpation of a closed wood frog population was likely if larvae or metamorphs were exposed to ranavirus once every 5 years.…”
