Studies of mating preferences have largely neglected the potential effects of individuals encountering their previous mates ('directly sexually familiar'), or new mates that share similarities to previous mates, e.g. from the same family and/or environment ('phenotypically sexually familiar'). Here, we show that male and female Drosophila melanogaster(More)
In principle, parental relatedness, parental age, and the age of parental gametes can all influence offspring fitness through inbreeding depression and the parental effects of organismal and postmeiotic gametic senescence. However, little is known about the extent to which these factors interact and contribute to fitness variation. Here, we show that, in(More)
In structured populations, competition for reproductive opportunities should be relaxed among related males. The few tests of this prediction often neglect the fact that sexual selection acts through multiple mechanisms, both before and after mating. We performed experiments to study the role of within-group male relatedness across pre- and postcopulatory(More)
Ocelots (Leopardus pardalis) are presumed to be the most abundant of the wild cats throughout their distribution range and to play an important role in the dynamics of sympatric small-felid populations. However, ocelot ecological information is limited, particularly for the Amazon. We conducted three camera-trap surveys during three consecutive dry seasons(More)
The changing surface of a comet From 2014 to 2016, the Rosetta spacecraft investigated comet 67P/Churyumov-Gerasimenko as it passed through the inner solar system. El-Maarry et al. compared images of the surface taken before and after the comet’s closest approach to the Sun. Numerous geological changes were evident, including cliff collapses, large boulders(More)
Managing large carnivores in human-inhabited areas is challenging as their large range requirements often brings them into conflict with people. Learning from an extraordinary historical example of large carnivore resilience in a human-occupied landscape, we detail the case of human-tiger interactions on a small (576 km2) island, Singapore.
