Abstract
Previous morphological work on lizards suggests that the volume of growing eggs may result in a significant decrease in lung volume during gravidity. Iguanid lizard lungs are located within continuous thoracic and abdominal cavities and are highly distensible. Because of their distensible nature and lack of a diaphragm, both naturally occurring and introduced structures within the abdominal and thoracic cavities (i.e. organs, food, eggs) compress them and potentially reduce available lung volume for gas exchange. During reproduction, this decrease comes at a time of increased energetic demands, due to the cost of provisioning eggs and the physical burden of transporting the extra mass before laying. This means that females must increase the oxygen/carbon dioxide exchange with effectively smaller lung capacity than when they are not reproductive. Therefore, the way species compensate for this decrease affects performance, and ultimately the survival of individuals and their offspring.

Comments
This dataset was originally published on the Long Term Ecological Research (LTER) Network Data Portal, https://portal.lternet.edu, and potentially via other repositories or portals as described. The Digital Object Identifier (DOI) of the source data package is doi:10.6073/pasta/3dc0b1d6822a10a38d3da6b254cb5779, and may be accessed at http://dx.doi.org/10.6073/pasta/3dc0b1d6822a10a38d3da6b254cb5779. Metadata and files included in this record mirror as closely as possible the source data and documentation, with the provenance metadata and quality report generated by the LTER portal reproduced here as '*-provenance.xml' and *-report.html' files, respectively.
