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

Viviparity evolved ~115 times across squamate reptiles, facilitating the colonization of cold habitats, where oviparous species are scarce or absent. Whether the ecological opportunity furnished by such colonization reconfigures phenotypic diversity and ...

A review and illustrated description of Musca Crassirostris, one of the most neglected livestock hematophageous flies [PDF]
Tabanids, stomoxyine flies, hippoboscids and tsetse flies are the most well‐known brachyceran biting flies of livestock. Only a few other higher Diptera have developed the unique mouthparts required for blood feeding.

Morphogenesis of propagules in viviparous species Bryophyllum daigremontianum and B. calycinum
The propagule development in two viviparous Bryophyllum species: B. daigremontianum and B. calycinum (Crassulaceae) has been found to proceed via embryoidogenesis (somatic embryo).
