Attack Time

AbstractIntroduction: In basketball, ball possession can begin and end in many different ways, for example, ball possession may begin with an out-of-bounds, a stolen ball, a rebound etc, and may also end with a throw, a turnover or when the attack time has expired.Aim: Starting from the working hypothesis that the backboard rebounds represent an important factor in gaining ball possession, we have proposed to identify and analyze the game parameters recorded in the national basketball leagues.Material and methods: The theoretical documentation included explaining, based on specialized literature, terms related to ball possession. Also, in order to accomplish the purposes of this research, we have used statistical analysis (possession, arithmetic mean, amplitude) and graphical representation. This study focused on all teams participating in the 2019-2020 season of the National Basketball Leagues (16 men’s and 13 women’s teams).Results: Following the analysis and centralization of the game parameters from the 146 games played in the men’s league and 144 games in the women’s league, we have identified the main ways of gaining ball possession.Conclusions: Backboard rebounds represent the main way of gaining ball possession (which confirms the hypothesis).

Simplified Analysis

In this chapter I consider the question of whether predators switch their preference for different types of prey as those prey change in abundance. There are numerous experiments in the literature focusing on this, but generally they have focused on a simplified analysis that ignores the functional response. Here I show why the functional response is crucial for understanding prey choice, and I show that null expectations considering a multi-species functional response lead to different interpretations than standard null expectations. I also derive null expectations for the proportion of prey consumed given the single-species functional response.

The Impact

The chapter considers the generalist and specialist diets of birds, and the behaviours and adaptations used by birds to find food. Special attention is given to the threat to birds from plastics pollution and the impact of plastic ingestion. Cooperative foraging and cooperative hunting are discussed as are the behaviours adopted by birds that do not cooperate or share. Feeding behaviour is considered in light of the theory of optimal foraging, particularly in relation to prey choice and to the balancing of risk. The impact of urban living upon the diets and foraging behaviours of birds is discussed. A broad range of predator avoidance behaviours are described and evaluated.
