Mother knows best: nest-site choice homogenizes embryo thermal environments among populations in a widespread ectotherm

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2023, Volume and Issue: 378(1884)

Species with large geographical ranges provide an excellent model for studying how different populations respond to dissimilar local conditions, particularly respect variation in climate. Maternal effects, such as nest-site choice greatly affect offspring phenotypes and survival. Thus, maternal behaviour has the potential mitigate effects of divergent climatic conditions across a species' range. We delineated natural nesting areas six painted turtles ( Chrysemys picta ) that span broad latitudinal range quantified spatial temporal nest characteristics. To quantify microhabitats available females choose, we also identified sites within area each location were representative thermal microhabitats. Across range, nested non-randomly targeted generally had less canopy cover thus higher temperatures. Nest differed among locations but did not predictably vary latitude or historic mean air temperature during embryonic development. In conjunction other studies these populations, our results suggest is homogenizing environments, which buffers embryos from thermally induced selection could slow evolution. although effective at macroclimatic scale, unlikely compensate novel stressors rapidly increase This article part theme issue ‘The evolutionary ecology nests: cross-taxon approach’.

Low Requirement on the Nest Site Selection Influencing the Invasion Success of House Geckos

ABSTRACT The selection of nesting sites is fundamental for the reproductive success oviparous species. However, there are gaps regarding how animals select their sites, especially among species that do not build nests; is, they use natural cavities oviposition, as case with many lizards. Herein, we evaluated physical structure and microclimatic conditions tree hollows influence oviposition in a widely distributed exotic lizard, Hemidactylus mabouia (Squamata, Gekkonidae). We hypothesized choice by females would consider: (a) structural properties related to vulnerability eggs predation; and/or (b) associated stability egg incubation process. Over course year, monitored 53 on weekly basis, recording total 69 H. nests. width opening height relation ground level, temperature variation did sites. less humidity were used more frequently. Our findings contribute understanding criteria nests general. Furthermore, discuss implications generalist habits context biological invasion, suggesting low requirements may constitute determining factor successful invasion

Natural nest substrates influence squamate embryo physiology but have little effect on hatchling phenotypes

Integrative Zoology, Journal Year: 2021, Volume and Issue: 17(4), P. 550 - 566

Published: May 18, 2021

Vertebrate embryos require access to water; however, many species nest in terrestrial habitats that vary considerably moisture content. Oviparous, non-avian reptiles have served as models understand how environmental factors, like availability, influence development because eggs are often exposed prevailing environments the absence of parental care. Though much research demonstrates importance water absorption by eggs, ecological factors availability natural nests received little attention. For example, type substrate which constructed is understudied. We experimentally incubated brown anole lizard (Anolis sagrei) 2 naturally occurring substrates were treated with varying amounts determine at different concentrations. One consisted sand and crushed seashells other was mostly organic material (i.e. decayed plant material). Both common nesting our field site. When controlling for uptake we found egg survival hatchling phenotypes similar between substrates; developed more quickly sand/shell than substrate, indicating substrate-specific effects on embryo physiology. These results demonstrate can result developmental outcomes if available comparable; some aspects development, rate, affected independent availability. Further study required physiology

Nesting in Anolis Lizards: An Understudied Topic in a Well-Studied Clade

Frontiers in Ecology and Evolution, Journal Year: 2022, Volume and Issue: 10

Maternal nesting behavior in oviparous species strongly influences the environmental conditions their embryos experience during development. In turn, these early-life have consequences for offspring phenotypes and many fitness components across an individual’s lifespan. Thus, identifying evolutionary ecological causes effects of is a key goal behavioral ecology. Studies reptiles contributed greatly to our understanding how shapes phenotypes. While some taxonomic groups been used extensively provide insights into this important area biology, remain poorly studied. For example, squamate genus Anolis has served as model study behavior, ecology, evolution, but research focused on developmental plasticity comparatively scarce. This dearth empirical may be attributed logistical challenges (e.g., difficulty locating nests), biological factors single-egg clutches hinder experimental designs), historical focus males research. Although there gap literature concerning interest ecology group grown recent years. paper, we (1) review existing studies anole plasticity; (2) highlight areas that are currently understudied discuss can contribute broader topics maternal global change biology); (3) guidelines studying field. Overall, provides foundation establishing anoles models plasticity.

Spawning substrate shift associated with the evolution of a female sexual characteristic in a family of fishes

Biological Journal of the Linnean Society, Journal Year: 2021, Volume and Issue: 133(1), P. 155 - 165

Abstract Because ‘primary’ sexual characteristics (i.e. those directly associated with reproduction) can be extremely variable, evolve quickly, and impacted by both natural selection, they are often considered excellent model systems in which to study evolution. Here, we explore the evolution of anal sheath, a trait hypothesized facilitate release proper placement eggs on spawning substrate, its relationship habitat maximum body size family fish (Fundulidae). In addition using phylogenetically informed statistics determine role preferred sheath length, reconstruct evolutionary history habitat. We then test for significant phylogenetic signal rate shifts Our results indicate that habitat, not significantly influences size, is signal, an similar substrate. discuss these terms potential mechanisms driving length.

Factors influencing tropical lizard reproduction vary by microhabitat but not forest type

Journal of Tropical Ecology, Journal Year: 2023, Volume and Issue: 39

Published: Jan. 1, 2023

Abstract To understand mechanisms behind enigmatic declines of tropical reptiles, knowledge species interactions and how they vary over space time is important. Some lizard population dynamics can be highly influenced by egg survival. Yet relatively few studies have examined relationships between reproductive success predators across forest microhabitat types. In this study, we variation in probability depredation, predatory ant abundance, prey availability, the number lizards eggs encountered four different types (abandoned agroforestry, abandoned plantation, secondary forest, old-growth forest) three microhabitats (buttress, fallen log, leaf-litter) at La Selva Biological Station, Costa Rica. Based on previous studies, made hypotheses about survival, numbers would related type. Of these hypotheses, only one was supported: found more buttress log than leaf-litter. We did not observe any differences reproduction or invertebrates type alone. patterns observed suggest that future investigating leaf-litter focus environmental scale.
