Environmental Thermal Stress Induces Neuronal Cell Death and Developmental Malformations in Reptiles

Integrative Organismal Biology, Год журнала: 2021, Номер 3(1)

Опубликована: Янв. 1, 2021

Every stage of organismal life history is being challenged by global warming. Many species are already experiencing temperatures approaching their physiological limits; this particularly true for ectothermic species, such as lizards. Embryos markedly sensitive to thermal insult. Here, we demonstrate that currently experienced in natural nesting areas can modify gene expression levels and induce neural craniofacial malformations embryos the lizard Anolis sagrei. Developmental abnormalities ranged from minor changes facial structure significant disruption anterior face forebrain. The first several days postoviposition development These results raise new concern over viability under contemporary climate change. Herein, propose test a novel developmental hypothesis describes cellular origins those malformations: cell death developing forebrain abnormal induction due disrupted Hedgehog signaling. Based on similarities embryonic response stress among distantly related represents common insult amniote embryos. Our emphasize importance adopting broad, multidisciplinary approach includes both lab field perspectives when trying understand future impacts anthropogenic change animal development.

Preforming floral primordia converge on a narrow range of stages at dormancy despite multiple effects of temperature on development

New Phytologist, Год журнала: 2021, Номер 233(6), С. 2599 - 2613

Summary Phenological studies often focus on relationships between flowering date and temperature or other environmental variables. Yet in species that preform flowers, anthesis is one stage of a lengthy developmental process, effects flower development the year(s) before are largely unknown. We investigated during preformation Vaccinium vitis‐idaea . Using scanning electron microscopy, we established scores for developing primordia examined air temperature, depth soil thaw, time year previous development. Onset initiation depends change greatest at early stages warmest months. Regardless season, all basal floral pause same whole‐plant dormancy. Once initiated, does not appear to be influenced by differences within range variation among our sites. There may strong endogenous flower‐level controls over development, particularly which morphogenesis ceases However, strength such internal face continuing extremes under changing climate unclear.
