Prey limitation drives variation in allometric scaling of predator-prey interactions
(2018-10-01)
Ecologists have long searched for a universal size-scaling constant that governs trophic interactions. Although this is an appealing theoretical concept, predator-prey size ratios (PPSRs) vary strikingly across and within ...
No evidence of predation causing female-biased sex ratios in marine pelagic copepods
(Oldendorf, 2013-12-12)
Although sex ratios close to unity are expected in dioecious species, biased sex ratios are common in nature. It is essential to understand causes of skewed sex ratios in situ, as they can lead to mate limitation and have ...
