Fluctuating and Stable High Temperatures Differentially Affect Reproductive Endocrinology of Female Pupfish

Housh, M J; Telish, J; Forsgren, K L; Lema, S C

2024 Integrative Organismal Biology

doi:10.1093/iob/obae003 pmid:38464886

SynopsisFor many fishes, reproductive function is thermally constrained such that exposure to temperatures above some upper threshold has detrimental effects on gametic development and maturation, spawning frequency, and mating behavior. Such impairment of reproductive performance at elevated...

Sample Size and Geometric Morphometrics Methodology Impact the Evaluation of Morphological Variation

Rummel, A D; Sheehy, E T; Schachner, E R; Hedrick, B P

2024 Integrative Organismal Biology

doi:10.1093/iob/obae002 pmid:38313409

SynopsisGeometric morphometrics has had a profound impact on our understanding of morphological evolution. However, factors such as sample size and the views and elements selected for two-dimensional geometric morphometric (2DGM) analyses, which are often dictated by specimen availability and...

Androgen Receptors in the Dermal Glands of Male and Female Ouachita Dusky Salamanders

Gunelson, A M; Tuong, M A; Staub, N L

2024 Integrative Organismal Biology

doi:10.1093/iob/obae001

SynopsisThe presence of androgens in female development is an important, yet often overlooked, topic. We tested for the presence of androgen receptors (ARs) in the dermal glands of male and female Desmognathus brimleyorum, a plethodontid salamander. This species engages in a courtship behavior...

The Metameric Echinoderm

Turner, R L

2024 Integrative Organismal Biology

doi:10.1093/iob/obae005 pmid:38558855

SynopsisAnimal phyla are distinguished by their body plans, the ways in which their bodies are organized. A distinction is made, for example, among phyla with bodies of many segments (metameric; e.g., annelids, arthropods, and chordates), others with completely unsegmented bodies (americ; e.g.,...

Screening H3 Histone Acetylation in a Wild Bird, the House Sparrow (Passer Domesticus)

Ray, D; Sheldon, E L; Zimmer, C; Martin, L B; Schrey, A W

2024 Integrative Organismal Biology

doi:10.1093/iob/obae004 pmid:38516554

SynopsisEpigenetic mechanisms are increasingly understood to have major impacts across ecology. However, one molecular epigenetic mechanism, DNA methylation, currently dominates the literature. A second mechanism, histone modification, is likely important to ecologically relevant phenotypes and...

Egg-Clutch Biomechanics Affect Escape-Hatching Behavior and Performance

Güell, B A; McDaniel, J G; Warkentin, K M

2024 Integrative Organismal Biology

doi:10.1093/iob/obae006 pmid:38585155

SynopsisArboreal embryos of phyllomedusine treefrogs hatch prematurely to escape snake predation, cued by vibrations in their egg clutches during attacks. However, escape success varies between species, from ∼77% in Agalychnis callidryas to just ∼9% in A. spurrelli at 1 day premature. Both...
