ABSTRACT

The ivory-billed woodpecker (Campephilus principalis), long suspected to be extinct, has been rediscovered in the Big Woods region of eastern Arkansas. Visual encounters during
2004 and 2005, and analysis of a video clip from April 2004, confirm the existence of at least one male. Acoustic signatures
consistent with Campephilus display drums also have been heard from the region. Extensive efforts to find birds away from the primary encounter site
remain unsuccessful, but potential habitat for a thinly distributed source population is vast (over 220,000 hectares).

    • "This methodology is adapted to identify some groups of species like baleen whales (Mellinger and Clark, 1997) or bats (Henriquez et al., 2014), to monitor acoustic habitats at large spatio-temporal scales in terrestrial and marine environments (Boebel et al., 2006;Mason et al., 2008;Qi et al., 2008;André et al., 2011;Gage et al., 2015;Merchant et al., 2015), and to be a part of the species and habitat conservation strategies. For instance, passive acoustic recording has been used in South Carolina byMoskwik et al. (2013)to search for the ivory-billed woodpeckers (Campephilus principalis), which is considered critically endangered or possibly extinct, and is a species living in old growth forests of the southeastern United States (Fitzpatrick et al., 2005;Bird Life International, 2013). A real-time bioacoustics-monitoring project with automated species identification has been proposed byAide et al. (2013)with the use of cellphone technologies to transmit and successively identify species. "

    ABSTRACT: Climate change is an important cause of the irreversible transformation of habitats, of the rapid extinction of species, and of the dramatic changes in entire communities, especially for tropical assemblages and for habitat- and range-restricted species, such as mountaintop and polar species.

    • "For example, the central rock-rat, Zyzomys pedunculatus, was rediscovered several times after assumed periods of extinction [61]. The greater akialoa, Hemignathus ellisianus, and the mythical ivory-billed woodpecker, Campephilus principalis, were rediscovered in 1969 [62] and 2004 [63], respectively, but neither has been observed since. Scheffers et al. [12] concluded that many of the 351 rediscovered species discussed in their study are likely to go extinct without significant conservation efforts. "

    ABSTRACT: Many scientists argue that our planet is undergoing a mass extinction event that is largely due to human influences. In this context, rediscoveries of species presumed to be extinct are encouraging and of great potential interest. During a 2003 expedition to New Caledonia, Bocourt's terrific skink, Phoboscincus bocourti, was unexpectedly rediscovered on a small islet by one of us. This skink species had been described from a single specimen collected around 1872 in New Caledonia. Since that time, however, no data on the species' biology, trophic interactions, or role in the ecosystem have been collected, making it difficult to follow the established conservation plan. In this study, we used a multidisciplinary approach involving natural history, anatomy, morphology, genetics, and stable isotopes to elucidate the ecology of Bocourt's terrific skink. Over the course of three different expeditions to the islet (total of 55 days across 2005 and 2012), we captured 4 individuals and observed another 4 individuals. The species' dentition and trophic ecology suggest that it is a top predator in its ecosystem and a major consumer of small terrestrial reptiles. Its high degree of genetic relatedness to another New Caledonian skink, which has a broad distribution, suggests that P. bocourti underwent genetic isolation at a geographical remote location, where dispersal or colonization was highly improbable. Moreover, the lack of genetic variation among the four individuals we captured may imply that a unique lineage, characterized by few inter-island exchanges, exists on the islet. Bocourt's terrific skink may be the largest terrestrial squamate predator alive in New Caledonia today. As a result, it is likely vulnerable to habitat modifications and especially the invasive rodents found on this islet. Further information is necessary to assess the conservation plans and practices in place as no concrete changes have been made since the species' rediscovery almost 10 years ago.
