The prey as patch model: optimal handling of resources with diminishing returns

Fishers (Paraty, RJ) and fish manipulation time: a variable associated to the choice for consumption and sale

“…Burger et al (2005) observed that the time invested in extracting energy from a prey (a carcass) using processing efforts as a proxy for patch residence also reflects in the mean foraging return rate. In our study,the foraging time is increased by the necessity of food manipulation when bones need to be taken out of the fish.…”

Archeological Testing and Data Recovery at 41ZV202, Zavala County, Texas

“…While this class of remains is frequently thought to have little analytical potential, the size categories such as very large (i.e., bison), large (e.g., deer, antelope), medium/small (e.g., coyote, jackrabbit), and very small (e.g., rat, mouse). To the degree that these fragments reflect increased processing of skeletal elements, either for marrow or bone grease, we expect that the fragmentation should be common during periods of dietary stress, as hunters should increasingly use marginal elements of animals when high return resources are not common (see Burger et al 2005;Cannon 2003;Outram 2001). We propose to use two measures to consider this proposition.…”

“…A second measure is the relative amount of the fragmented fauna that fall within the very large category. While very large (i.e., bison) and large (e.g., deer) herbivores should be the target of marrow and grease extraction during all periods, this should especially be the case during periods of stress (Burger et al 2005;Cannon 2003 …”

Mobility patterns and control of the Eastern Cantabrian territory during late Last Glacial

“…Siguiendo la filosofía de la Teoría del Forrajeo Óptimo, los distintos valores que componen la curva se han obtenido suponiendo que el procesado de las distintas partes anatómicas seguiría el orden de mayor a menor eficacia (Burger et al 2005). Adicionalmente, el transporte de partes no procesadas hasta completar la carga máxima transportable seguiría el orden de mayor a menor de Cervus elaphus.…”
