The first domestications of plants and animals, which occurred between 10 K years and 5 K years BP, and which underpinned the inception of agricultural systems, represent a major turning point in cultural and environmental history. New methods
of age estimation, notably by radiocarbon, have necessitated a reappraisal of the origins of agriculture in Mesoamerica, whilst biomolecular techniques are contributing to the identification of the wild relatives of domesticated plants and animals

This paper describes teeth and bone fragments recovered from the peaty deposit during a search for coleopterain remains. The paper also summarises some of the Coleoptera and plant remains previously described and comments on the ecological
subtances involved in the arms race between plant producers and animal consumers, the evolutionary mechanisms implied in coevolution, the costs and benefits of the alternative adaptive strategies adopted by insect consumers (with particular emphasis
Compared to English, Spanish exhibits a more subtle use of place-of-margins words. Spanish has a rich lexicon for elements of the natural lanscape, but is not well suited to naming plants and animals according to concrete semantic categories. - (DWG)
to discourage consumption by animal consumers. Two phytochemical tactics can be identified: (1) the T-tactic, based on the mass use of molecules (tannins and terpenoids) which influence the palatability and digestibility of plant material, and (2) the a-tactic
A negative correlation is shown to exist between the frequencies of occurrence of tannins and alkaloids among the major orders and families of Dicotyledons (and other Spermatophytes as well). Tannins and alkaloids are both used by plants

Geographers have begun to consider animals and the urban moral landscape, and assess competing rubrics of planning practice as they relate to animals in the city. Together, these efforts suggest a research agenda for urban geographers interested
in human-animalrelations, that may help bridge gaps between human and physical geography, and propel the study of nature-society relations to the fore in urban geography.

The diet of the lizard Psammodromus algirus was studied on the small Isola dei Conigli, near lampedusa, Sicily. A comparison is made with diet of the population studied by Mellado (1975) in the south of Spain. Both plant and animal remains were
found in the fecal pellets of the Isoli dei Conigli lizards, contrary to what has been found in Spain. Ants, beetles and spiders were the principal animal prey.

This paper seeks to develop a ‘more-than-human’ cosmopolitanism that accounts for the presence of nonhuman animals and entities in stories of circulation and contact. Through a multi-sited ethnography of elephant conservation in India and the UK
, the paper illustrates how animals become participants in forging connections across difference. Through their circulation, elephants become cosmopolitan, present in diverse cultures and serving banal global consumption. The paper then illustrates how
