Identification guide to amphibians and reptiles of mexico

This article analyzes in an interdisciplinary way the human-animal relationships of a group of artisanal fishermen in Argentina, whose trade leads them to incidentally capture threatened marine mammals and reptiles. We will address the interaction between this community and a group of biologists who seek the conservation of these species. Our hypothesis is that the human-animal relationships involved in the artisanal fishing practice of this community can be explained from a juxtaposition of the three paradigms defined by Pálsson (2001): the orientalist, the paternalist and the communalist. Although fishermen classify animal species according to their possibility of being exploited as a resource, they eventually negotiate with biologists for the protection of some of these species, reinventing themselves as strategic conservationists. The coexistence of the first two paradigms does not obscure the tacit communalism that permeates the fishermen's world of work and life.

Joan Beauchamp Procter FZS, FLS (London, August 5, 1897 - ibid, September 20, 1931) was a leading British zoologist, internationally recognized for her work in herpetology. She worked initially at the Natural History Museum in London and later at the Zoological Society of London, and as the first woman curator of reptiles at London Zoo. Her life was short, conditioned by chronic ill health. However, she did significant taxonomic work, and made important innovative contributions to veterinary practice and in zoo exhibits. She also wrote scientific articles on zoology and popular science, including early accounts of the behavior of Komodo dragons in captivity.

Joan Procter was born in London on August 5, 1897. She was the daughter of Joseph Procter, a stockbroker, and Elizabeth Procter, an artist. Her grandfather William Brockbank was an art lover and also an amateur botanist and geologist. Family interests in the arts and sciences influenced both Joan and her sister Chrystabel Prudence Goldsmith Procter (1894-1982). The family home boasted large gardens, which facilitated the sisters' childhood pursuits in natural history.[1] The family's home was a place where they were able to enjoy the natural history of the world.

Amphibians and reptiles characteristics

By observing and comparing fossil remains, the paleontologist finds evidence of the characteristics and evolution of life through time. The study of fossils is essentially morphological-comparative, which allows for interpretations in the fields of functional anatomy, systematics, evolution, paleoecology, paleobiogeography, taphonomy, biostratigraphy, etc. Paleontology allows us to understand the current biodiversity and distribution of living beings on Earth and offers tools for the analysis of how climatic and geological phenomena could affect our planet in the future.

What is a fossil? A fossil is any remains or evidence of an extinct organism. In the case of vertebrates, the most common remains are usually teeth and fossilized bones; but footprints (ichnites), eggs (oolites), excrement (coprolites) and, in exceptional cases, soft tissues such as remains of skin, hair, feathers or cartilage have also been preserved.

The DPV is located in the basement of the main building of the Museum and has areas for: (a) research and specialized library, (b) preparation and conservation of fossils, and (c) the scientific collection of vertebrate fossils.
