  • effects of el nino on the population dynamics of the malay civet east of the Wallace Line
    Journal of Zoology, 2017
    Co-Authors: A S Seymour, M R Tarrant, Brian D Gerber, A Sharp, J Woollam
    Abstract:

    The effect of climate on the population dynamics of rainforest vertebrates is known only for a limited subset of species and study locations. To extend this knowledge, we carried out an 8-year population study of a Viverrid (Malay civet Viverra tangalunga) in the Wallacea biogeographical region (Buton Island, Sulawesi). Civets were trapped annually from 2003 to 2010, during which there were four weak to moderate El Nino events and one moderate La Nina event. In Indonesia, El Nino events are associated with drier than normal conditions, while La Nina is associated with wetter conditions. The number of individuals captured was strongly correlated with the 12-month summed Southern Oscillation Index (SOI) prior to trapping, with significantly fewer individuals caught in years with lower summed SOI (i.e. stronger El Nino conditions). Adult civet body mass was significantly higher in El Nino years; mean adult male and female body masses were 10.6% and 4.0% greater in El Nino years. There was support for a 1-year time lagged effect of El Nino on the apparent survival (1 – probability of disappearing from the study site due to death or emigration) of male (but not female) civets, which was approximately 50% higher in the year following El Nino events. Using spatially explicit capture–mark–recapture models, we were unable to detect any significant change in civet density between years, which was estimated as 1.36 ± 0.14 (se) individuals km−2. We suggest that increased apparent survival of males observed in the year after El Nino events was brought about by reduced dispersal (possibly associated with a change in mating tactic) rather than reduced mortality.

  • A new species of Homo from the Late Pleistocene of the Philippines
    Nature, 2019
    Co-Authors: Florent Detroit, Armand Salvador B Mijares, Julien Corny, Guillaume Daver, Clement Zanolli, Emil Robles, Rainer Grun, Eusebio Dizon, Philip J. Piper
    Abstract:

    Homo luzonensis , a new species of Homo from the Callao Cave in the Philippines from the Late Pleistocene epoch, is described. A hominin third metatarsal discovered in 2007 in Callao Cave (Northern Luzon, the Philippines) and dated to 67 thousand years ago provided the earliest direct evidence of a human presence in the Philippines. Analysis of this foot bone suggested that it belonged to the genus Homo , but to which species was unclear. Here we report the discovery of twelve additional hominin elements that represent at least three individuals that were found in the same stratigraphic layer of Callao Cave as the previously discovered metatarsal. These specimens display a combination of primitive and derived morphological features that is different from the combination of features found in other species in the genus Homo (including Homo floresiensis and Homo sapiens ) and warrants their attribution to a new species, which we name Homo luzonensis . The presence of another and previously unknown hominin species east of the Wallace Line during the Late Pleistocene epoch underscores the importance of island Southeast Asia in the evolution of the genus Homo .
