Data from: Phenotypic evolution shaped by current enzyme function in the bioluminescent courtship signals of sea fireflies
Mating behaviours are diverse and noteworthy, especially within species radiations where they may contribute to speciation. Studying how differences in mating behaviours arise between species can help us understand how diversity is generated at multiple biological levels. The bioluminescent courtship displays of cypridinid ostracods (or sea fireflies) are an excellent system for this since amazing variety evolves while using a conserved biochemical mechanism. We find that the evolution of one aspect in this behavioural phenotype - the duration of bioluminescent courtship pulses - is shaped by biochemical function. First, by measuring light production from induced bioluminescence in 38 species, we discovered differences between species in their biochemical reactions. Then, for 16 species of which biochemical, phylogenetic, and behavioral data are all available, we used phylogenetic comparative models to show that differences in biochemical reaction are nonlinearly correlated with the duration of courtship pulses. This relationship indicates that changes to both enzyme (c-luciferase) function and usage have shaped the evolution of courtship displays, but that they differentially contribute to these phenotypic changes. This nonlinear dynamic may have consequences for the disparity of signaling phenotypes observed across species, and demonstrates how unappreciated diversity at the biochemical level can lead to inferences about behavioural evolution.
Haplocauda, a new genus of fireflies endemic to the Amazon Rainforest (Coleoptera: Lampyridae)
<p>Most firefly genera have poorly defined taxonomic boundaries, especially in the Neotropics, where they are more diverse and more difficult to identify. Recent advances that shed light on the diversity of fireflies in South America have focused mainly on Atlantic Rainforest taxa, whereas lampyrids in other biomes remained largely unstudied. We found three new firefly species endemic to the Amazon basin that share unique traits of the male abdomen where sternum VIII and the pygidium are modified and likely work as a copulation clamp. Here we test and confirm the hypothesis that these three species form a monophyletic lineage and propose Haplocauda gen. nov. to accommodate the three new species. Both Maximum Parsimony and probabilistic (Bayesian and Maximum Likelihood) phylogenetic analyses confirmed Haplocauda gen. nov. monophyly, and consistently recovered it as the sister group to Scissicauda, fireflies endemic to the Atlantic Rainforest that also feature a copulation clamp on abdominal segment VIII, although with a different configuration. We provide illustrations, diagnostic descriptions, and keys to species based on males and females. The three new species were sampled from different regions, and are likely allopatric, a common pattern among Amazonian taxa.</p>
Life-history traits modulate the influence of environmental stressors on biodiversity: the case of fireflies, climate, and artificial light at night
Aim Artificial light at night (ALAN) is an unprecedented stressor recently introduced in the abiotic milieu of natural landscapes. As such, understanding how ALAN and other natural stressors act in concert to shape the spatial distribution of biodiversity is a core goal in conservation ecology. Here, we aim at understanding how ALAN and climate interact with life-history traits and courtship signalling systems to dictate the composition of firefly communities in a global biodiversity hotspot. Location An extensive elevational gradient in the Atlantic Rainforest (Brazil) currently known as the hottest hotspot of fireflies on Earth. Methods We used multivariate species distribution models to understand how species traits and courtship signalling systems interact with climate and ALAN to determine species abundances within firefly communities. We also investigated how species-specific responses to climate and ALAN scale up to determine compositional changes in firefly communities along the elevational gradient. Results We found that climate shapes communities by filtering species according to their body size and trophic position. ALAN dictates the dominant courtship signalling system within communities by affecting the abundance of species that use bioluminescence or a combination of bioluminescence and pheromones in courtship. We also found that associations between beta-diversity and ALAN were non-stationary, being higher in regions under low levels of light pollution. This suggests that even incipient increases in ALAN within protected areas can yield fast changes in the composition of firefly communities. Main Conclusions Firefly responses to climate and ALAN are modulated by traits associated with different facets of their life histories. Given the alarming changes in both stressors predicted for the foreseeable future, our findings indicate that firefly communities are vulnerable to compositional changes even within protected areas. --
Video recording of the collective display of Photuris frontalis fireflies
<p><em>Photuris frontalis</em> fireflies are known for their synchronous flashing when swarming in large numbers. Here, we provide a continuous, high-resolution video recording of their collective display. This recording was obtained at Congaree National Park, South Carolina, USA, on May 23, 2021, in the fireflies' natural habitat. It started at 8:38 pm EDT and continued for about 130 min without human interference. The flashes seen in the video appear usually synchronous, and at times produce more complex patterns akin to the mathematical phenomenon known as "chimera state".</p>
