The body size is one of the most important attributes of an organism from an ecological and evolutionary point of view as mentioned in this paper, and it has a predominant influence on an animal's energetic requirements, its potential for resource exploitation, and its susceptibility to natural enemies.Abstract:
Body size is manifestly one of the most important attributes of an organism from an ecological and evolutionary point of view. Size has a predominant influence on an animal's energetic requirements, its potential for resource exploitation, and its susceptibility to natural enemies. A large literature now exists on how physiological, life history, and population parameters scale with body dimensions (24, 131). The ecological literature on species interactions and the structure of animal communities also stresses the importance of body size. Differences in body size are a major means by which species avoid direct overlap in resource use (153), and size-selective predation can be a primary organizing force in some communities (20, 70). Size thus imposes important constraints on the manner in which an organism interacts with its environment and influences the strength, type, and symmetry of interactions with other species (152, 207). Paradoxically, ecologists have virtually ignored the implications of these observations for interactions among species that exhibit size-distributed populations. For instance, it has been often suggested that competing speciesread more

TL;DR: This work has shown that predation is a major selective force in the evolution of several morphological and behavioral characteristics of animals and the importance of predation during evolutionary time has been underestimated.

A distributed, architecture-centric approach to computing accurate recommendations from very large and sparse datasets
Hossein Saiedian,Serhiy Morozov +1 more
TL;DR: This work introduces a novel architecture model that supports scalable, distributed suggestions from multiple independent nodes, and proposes a novel algorithm that generates a more optimal recommender input, which is the reason for a considerable accuracy improvement.

Stock and Recruitment
TL;DR: Plotting net reproduction (reproductive potential of the adults obtained) against the density of stock which produced them, for a number of fish and invertebrate populations, gives a domed curve whose apex lies above the line representing replacement reproduction.

TL;DR: This study presents an experimental evaluation of the effects of natural physical disturbances and competitive interactions on populations of sessile organisms in the rocky intertidal community, for which space can be demonstrated to be the most important limiting resource.
