It is tautological to say that an organism is adapted to its environment. It is even tautological to say that an organism is physiologically adapted to its environment. However, just as in the case of many morphological characters, it is unwarranted to conclude that all aspects of the physiology of an organism have evolved in reference to a specific milieu. It is equally gratuitous to assume that an organism will inevitably show physiological specializations in its adaptation to a particular… 
Limitations to algal growth in the Galapagos Islands: its consequences on the breeding strategy of the marine iguana Amblyrhynchus cristatus
TLDR
Exclusion caging experiments were used to determine if the short, cropped appearance of the Ulva was due to heavy grazing by the iguana, and negative algal growth was found in both the excluded and grazed areas.
The Effects of Algal Abundance in an Energy Sensitive Environment on the Galapagos Island Marine Iguana
TLDR
The relationship between algal abundance and quality and its effects on the fitness and reproductive timing of the marine iguana are discussed.
Eocene Lizards of the Clade Geiseltaliellus from Messel and Geiseltal, Germany, and the Early Radiation of Iguanidae (Reptilia: Squamata)
TLDR
The presence of Geiseltaliellus in Europe during the warm, humid Eocene suggests dispersal from North America and a more northerly distribution of the corytophanine stem than the crown.
The Postcranial Skeleton of the Aquatic Parareptile Mesosaurus tenuidens from the Gondwanan Permian
TLDR
The postcranial skeleton of Mesosaurus tenuidens, a reptile from the Lower Permian of eastern South America and southern Africa, is redescribed and illustrated in detail, suggesting strongly that this reptile was fully dedicated to an aquatic lifestyle.
The cranial skeleton of the Early Permian aquatic reptile Mesosaurus tenuidens: implications for relationships and palaeobiology
TLDR
Emendation of problematic characters and reanalysis of amniote phylogeny using a slightly modified data matrix from the literature strengthens the hypothesis that mesosaurs form a clade with millerettids, procolophonoids and pareiasaurs within Reptilia.
A new rhynchocephalian (Reptilia: Lepidosauria) from the Late Jurassic of Solnhofen (Germany) and the origin of the marine Pleurosauridae
TLDR
The insight Vadasaurus provides into the origin of the enigmatic pleurosaurs exemplifies the potential of Rhynchocephalia for generating and informing broad-based questions regarding the interplay of development, morphology, ecology and macroevolutionary patterns.
Conflicting evidence for the use of caudal autotomy in mesosaurs
TLDR
It is suggested that the presence of fracture planes in mesosaurs is an evolutionary relic and could represent a synapomorphy for an as-yet undetermined terrestrial clade of Palaeozoic amniotes that includes the earliest radiation of secondarily aquatic tetrapods.
The Mystery of a Marine Monster: Morphological and Performance Modifications in the World’s only Marine Lizard, the Galápagos Marine Iguana
TLDR
It is found that specialisation for the marine environment resulted in a trade-off in sprint speed in a terrestrial environment, similar to that seen in extant crocodilians, suggesting that iguanids and other ancestral lineages have not undergone transitions to aquatic life.
Morphological and performance modifications in the world’s only marine lizard, the Galápagos marine iguana, Amblyrhynchus cristatus
TLDR
Examining the morphology and locomotory performance of the marine iguana in comparison to their closely related mainland ancestors, the black spiny-tailed iguana and green iguana, finds variation reflected specialization to ecological niches, but the magnitude of morphological and performance variation was more pronounced among subspecies than between iguanid species.
AN UNUSUAL AQUATIC SPHENODONTIAN (REPTILIA: DIAPSIDA) FROM THE TLAYUA FORMATION (ALBIAN), CENTRAL MEXICO
TLDR
Cladistic analysis support sister-group relationship with Toxolophosaurus and/or Eilenodon on the basis of shared propalinal jaw action and deep jaws and the presence of two unique sphenodontians in the Tlayua Quarry suggests that this area was a refuge for archaic forms at the time.

Lizard Energetics and Diet
TLDR
It is postulated that larger animals of these families are unable to get caloric demands on a diet of insects, have no practical alternative animal prey, and rely instead on vegetation.
Swimming, Diving and Lactate Production of the Marine Iguana, Amblyrhynchus cristatus
The swimming and diving performance of hatchling, juvenile and adult marine iguanas, and the effects of these activities on blood lactate in juveniles were studied under field conditions at Academy
Galapagos iguanas: Amblyrhynchus and Conolophus serum protein relationships.
TLDR
The serum proteins of two genera of Galapagos iguanas were studied by means of immunochemical and electrophoretic methods and it was indicated that the antigenic profile of the Santa Cruz, Hood, Tower, Albemarle and James Island populations of Amblyrhynchus were identical.
