In nutritional ecology the intake target is the diet that maximises consumer fitness. A key hypothesis of nutritional ecology is that natural selection has acted upon the behavioural and physiological traits of consumers to result in them Selectively Consuming prey to match the Intake Target (SCIT)....
Analytical studies of carnivore functional and evenness richness across the Pliocene and Pleistocene in East Africa show that there has been a loss of functional richness > 99% from the Pliocene until today78. Climatic and environmental information does not correlate with carnivore extinctions, ...
For this reason, some palaeoecological studies (e.g. ref.38,62) have attempted to correct for these biases with reference to a relationship describing the ratio of standing crop abundance on the landscape to skeletal abundance as a function of body size. The relevant data were collected for ...
Conservation measures grounded in scientific studies can reduce these negative effects and allow carnivore populations to recover. Availability of prey is one of the primary factors related to carnivore abundance4. Thus, precise knowledge on diet composition and prey availability are needed to define ...

obesity and economic development. Prospective cohort studies of individuals, in which diet is assessed prior to the occurrence of disease, are typically considered to be the strongest non-randomized design. Despite the long-standing interest in the diet-heart hypothesis, the number of cohort studies...
The teeth of Herrerasaurus indicate that it was a carnivore; its size indicates it would have preyed upon small and medium-sized plant eaters. These might have included other dinosaurs, such as Pisanosaurus, as well as the more plentiful rhynchosaurs and synapsids.[65] Herrerasaurus itself may...
with over 40% preserved, but she was one of the smaller specimens of her species. Nonetheless, she has been the subject of several body mass estimates since her discovery, ranging from 13–42 kg (29–93 lb) for absolute lower and upper bounds. Most studies report ranges within 25–37 kg...
Studies examining narrower ranges of body sizes, e.g., within a single species, have produced mixed results, finding evidence for negative allometry in some cases12,13,14 but not others15,16,17,18. The principal challenge in conducting large-scale interspecific studies of size-frequency ...
