Heloderma horridum is one of the few known venomous lizards in the world. Their populations are in decline due to habitat destruction and capture for the pet trade. InMéxico, many zoos have decided to take care of this species, most of them at altitudes greater than the natural altitudinal distribution. However, we know little about the capacity of the reptiles to face high-altitude environments. The objective of this study was to compare hematological traits of H. horridumin captivity in high and low altitude environments. Our findings show that H. horridum does not respond to hypoxic environments, at least in blood traits, and that the organisms appear to be in homeostasis. Although we cannot know if individual H. horridum housed in high-altitude environments are completely comfortable, it appears hypoxia can be avoid without modifications of blood parameters. We suggest that future work should address changes in metabolic rates and in behavioral aspects to understand how to maintain the health and comfort of the reptiles native to low altitude when they are housed in high-altitude environments.

Quantifying biodiversity patterns in the context of human-caused environmental degradation is a fundamental task to improve conservation strategies; yet, it can be difficult given the rapid increase of available analytical methods. To guide studies on the topic, in this brief essay we present four approaches, accompanied by empirical examples, that can be used to accurately assess the impact of human activities on different facets of biological diversity. Such approaches include: (1) measurement of alpha diversity by incorporating interpolation-extrapolation techniques, Hill numbers and rank-abundance graphs; (2) beta diversity and its components of turnover and richness differences due to nestedness; (3) functional diversity, and (4) phylogenetic diversity. We highlight that a critical assessment, understanding and appropriate application of these and other emerging concepts and methods to assess biodiversity is needed to support both theoretical and applied studies, especially in biological conservation.

La diversidad funcional es un enfoque de investigación que determina las relaciones entre diversidad, estructura y funcionamiento de las especies al interior de los ecosistemas, evaluando en ellas las contribuciones que resultan clave para el entorno. La contribución funcional de los organismos podría ser inversamente proporcional a su diversidad numérica, como lo demostró un estudio sobre mamíferos en el Neotrópico.
