Demographic analysis for article Hurricane-induced demographic changes in a nonhuman primate population

Raisa Hernández-Pacheco, Dana O Morcillo, Ulrich K Steiner, Angelina V Ruiz-Lambides & Kristine L Grayson
Major disturbance events can have large impacts on the demography and dynamics of animal populations. Hurricanes are one example of an extreme climatic event, predicted to increase in intensity due to climate change, and thus expected to be a considerable threat to population viability. However, little is understood about the underlying demographic mechanisms shaping population response following these extreme disturbances. Here, we analyze 45 years of the most comprehensive free-ranging nonhuman primate demographic dataset to...

Identifying drivers of forest resilience in long-term records from the Neotropics

Carole Adolf, Carolina Tovar, Nicola Kühn, Hermann Behling, Juan Carlos Berrío, Gabriela Dominguez-Vázquez, Blanca Figueroa-Rangel, Zaire Gonzalez-Carranza, Gerald Alexander Islebe, Henry Hooghiemstra, Hector Neff, Miguel Olvera-Vargas, Bronwen Whitney, Matthew J. Wooller & Kathy J. Willis
Here we use 30 long-term, high-resolution palaeoecological records from Mexico, Central and South America to address two hypotheses regarding possible drivers of resilience in tropical forests as measured in terms of recovery rates from previous disturbances. First, we hypothesise that faster recovery rates are associated with regions of higher biodiversity, as suggested by the insurance hypothesis. And second, that resilience is due to intrinsic abiotic factors that are location specific, thus regions presently displaying resilience...

Multilevel selection on offspring size and the maintenance of variation

Hayley Cameron, Darren Johnson, Keyne Monro & Dustin Marshall
Multilevel selection on offspring size occurs when offspring fitness depends on both absolute size (hard selection), and size relative to neighbours (soft selection). We examined multilevel selection on egg size at two biological scales: within clutches and among females, for an external fertilising tubeworm. We exposed clutches of eggs to two sperm environments (limiting and saturating) and measured their fertilisation success. We then modelled environmental (sperm) differences in hard and soft selection on individual eggs,...
