Developmental stage ordering yields greater cranial mineralization sequence resolution than embryo size or days since oviposition: A case study using the gekkotan Eublepharis macularius (Blyth, 1854)

open access: yesJournal of Anatomy, EarlyView.
We employ a set of leopard gecko embryos for which size, day of development, and developmental stage are known to assess which timetable accords with the greatest resolution of cranial mineralization events. Developmental staging yielded the best outcome. Abstract Mineralization sequences of cranial elements (often referred to as ossification sequences)

Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

open access: yesThe Anatomical Record, Volume 309, Issue 6, Page 1583-1598, June 2026.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Climate, geographic distribution and viviparity in Liolaemus (Reptilia; Squamata) species: when hypotheses need to be tested [PDF]

open access: yes, 2014
La distribución de los reptiles, dada su dependencia de la temperatura, puede verse restringida en función del clima. En particular, se han planteado tres hipótesis que vinculan el clima con la distribución y el viviparismo en las especies de reptiles: i)

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

open access: yesJournal of Anatomy, Volume 248, Issue 6, Page 1002-1025, June 2026.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...

Los poros precloacales como diferenciadores de sexo en Liolaemus (Squamata: Liolaemidae): el caso de L. jamesi (Boulenger, 1891)

open access: yesGayana, 2020
La presencia de poros precloacales se utiliza con frecuencia en Liolaemus para diferenciar a machos de hembras. Actualmente este carácter es confuso en Liolaemus jamesi porque se ha descrito la presencia y ausencia de poros en las hembras.

Ámbito de hogar y uso de microhábitat de Liolaemus forsteri (Iguania: Liolaemidae) en una región altoandina de La Paz, Bolivia

open access: yesActa Zoológica Lilloana, 2023
El conocimiento del ámbito de hogar (AH) y del uso del hábitat de las especies es importante para comprender sus requisitos ecológicos. Evaluamos el AH y el uso de microhábitat de Liolaemus forsteri, una especie endémica de los Andes de Bolivia ...

Pre‐oviposition development of the brown anole (Anolis sagrei)

open access: yesDevelopmental Dynamics, Volume 255, Issue 2, Page 145-167, February 2026.
Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

Altitudinal zonation among lizards of the genus Liolaemus: questions answered and unanswered questions Zonación altitudinal en lagartijas del género Liolaemus: preguntas respondidas y pendientes

open access: yesRevista Chilena de Historia Natural, 2001
We review factors influencing Liolaemus distributions in the central Chilean Andes and suggest areas of future research. Our previous studies reveal that lizard parasites (ectoparasitic mites and ticks, and the endoparasite Plasmodium) do not set ...
