Asymmetric acoustic signal recognition led to asymmetric genetic introgression between two parapatric rhacophorid treefrogs
<p><span>Correct discrimination between courtship signals could help maintain genetic integrity between closely related species. However, asymmetric usage of signals might cause asymmetric magnitude of gene flow across the contact zone. <i>Buergeria japonica </i>and <i>B. otai </i>are sibling species with parapatric distribution pattern in Taiwan, forming two narrow contact zones in eastern and western sides of the island. Both species use a shared acoustic signal of calls (Type 1a/1b), whereas <i>B. otai </i>presents another unique call type (Type 2) which never appears in <i>B. japonica</i>. Combining behavioral experiments with genome-wide RAD-seq analyses, we aim to test whether the ability of signal recognition influences genetic introgression across their species boundary. The playback experiments showed that the western population of <i>B. otai</i> has evolved a stronger level of reproductive character displacement by showing the inclusive usage of their unique Type 2 signal. In contrast, the eastern population used both unique and shared signals and has a stronger preference for the latter. Consistent with behavioral difference, genetic introgression across the contact zone was detected only in the eastern boundary but not in the western one. Furthermore, the gene flow in this contact zone tends to be unidirectional from <i>B. japonica</i> toward <i>B. otai</i>. Our results support the prediction that a more specialized signal user might have a higher probability to maintain their genetic integrity compared to a generalized signal user.</span></p>
Data from: Plasticity-led evolution: evaluating the key prediction of frequency-dependent adaptation
Plasticity-led evolution occurs when a change in the environment triggers a change in phenotype via phenotypic plasticity, and this pre-existing plasticity is subsequently refined by selection into an adaptive phenotype. A critical, but largely untested prediction of plasticity-led evolution (and evolution by natural selection generally) is that the rate and magnitude of evolutionary change should be positively associated with a phenotype's frequency of expression in a population. Essentially, the more often a phenotype is expressed and exposed to selection, the greater its opportunity for adaptive refinement. We tested this prediction by competing against each other spadefoot toad tadpoles from different natural populations that vary in how frequently they express a novel, environmentally induced carnivore ecomorph. As expected, lab-reared tadpoles whose parents were derived from populations that express the carnivore ecomorph more frequently were superior competitors for the resource for which this ecomorph is specialized—fairy shrimp. These tadpoles were better at utilizing this resource both because they were more efficient at capturing and consuming shrimp and because they produced more exaggerated carnivore traits. Moreover, they exhibited these more carnivore-like features even without experiencing the inducing cue, suggesting that this ecomorph has undergone an extreme form of plasticity-led evolution––genetic assimilation. Thus, our findings provide evidence that the frequency of trait expression drives the magnitude of adaptive refinement, thereby validating a key prediction of plasticity-led evolution specifically and adaptive evolution generally.

The first comprehensive revision of all the species attributed to Melomys led J. I. Menzies in 1996 to resurrect the genus Paramelomys and to redefine its morphologicallimits and species content. Menzies created P. gressitti as a new species belonging to a group displaying morphological similarities and including also P. lorentzii and P. moncktoni. Monotypic Distribution. E New Guinea. Descriptive notes. Head-body 135-162 mm, hindfoot 30-34 mm; no specific data are available for body weight. Gressitt's Mosaic-tailed Rat is a medium-sized Paramelomys with a soft, thick and woolly pelage, a long narrow foot, and a tail with three hairs per scale. It exhibits a medium-sepia dorsal pelage and a gray-buff ventral one. Tail is slightly shorter (99%) than head-body length. The skull has a narrow zygomatic plate. Habitat. Moist tropical mountain forest between 2300 m and 2400 m. Food and Feeding. No information. Breeding. No information. Activity patterns. Gressitt's Mosaic-tailed Rat is terrestrial. Movements, Home range and Social organization. No information. Status and Conservation. Classified as Endangered on The IUCN Red List owing to its small geographic range (less than 3500 km?*) and the destruction ofits habitat by mining and logging activities. The major threat to Gressitt's Mosaic-tailed Rat is ongoing habitat degradation caused by nearby human populations; habitat on Mount Kandy has been destroyed by gold-miners and wood-cutters.

Observing scenarios simulations for HLVK-Configuration for O4 Runs, using 20 million injections. This simulation led to 17,009 BNS useful for training Parameter Estimations of EM counterparts of GW. (July 2024 edition).
<p>We have conducted a simulation of the HLVK-configuration deployed during the ongoing O4 run. This project supports the training of kilonova regression with machine learning processes, requiring thousands of BNS to pass the threshold cutoff. Here we have 17,009 BNS passing the SNR threshold, along with 3,148 NSBH and 121,718 BBH, from 20 million CBCs injected. The upper-lower limit between NS and BH is 3 sun masses.</p> <p>Due to the large file sizes, we have split them into three parts and uploaded them to Zenodo with the following DOIs:<br><br></p> <ol> <li><strong>The first files is located :</strong> <code>runs_part_aa</code> and <code>runs_part_ab</code> : <a title="https://zenodo.org/doi/10.5281/zenodo.12693652" href="../doi/10.5281/zenodo.12693652">https://zenodo.org/doi/10.5281/zenodo.12693652</a></li> <li><strong>The second files is located : </strong><code>runs_part_ac</code> and <code>runs_part_ad</code> : <a href="../doi/10.5281/zenodo.12694779">https://zenodo.org/doi/10.5281/zenodo.12694779</a></li> <li><strong>The third files is located : </strong><code>runs_part_ae</code> and <code>runs_part_af</code> : <a href="../doi/10.5281/zenodo.12696695">https://zenodo.org/doi/10.5281/zenodo.12696695</a></li> </ol> <blockquote> <p>Download them or use this Python script from GitHub to download all of them by running the script: </p> <p> <a href="https://github.com/weizmannk/ObservingScenariosInsights/blob/main/chunk-xml/zenodo-process/download_split_chunk_data.py">hchunk-files-downloader</a>.</p> </blockquote> <p>After downloading them (6 files ), you will need to combine them in a single file using the following process:</p> <blockquote> <p>1.Combine the parts:<br><code>cat runs_part_* > runs.zip</code></p> </blockquote> <blockquote> <p>2.Verify the combined file:<br><code>ls -lh runs.zip</code><br><code>file runs.zip</code></p> </blockquote> <blockquote> <p>3.Unzip the combined file:<br><code>unzip runs.zip</code></p> </blockquote> <p> </p> <p>In the <code>runs</code> folder, we have three subfolders:</p> <ul> <li><code>O4</code>: This contains the <code>.fits</code> files for skymap localization and all GW parameters of the CBCs that passed the threshold cutoff of 8.</li> <li><code>statistics_results</code>: This contains the summary results of the statistical predictions of GW detections.</li> <li><code>subpopulations</code>: This folder is the split of BNS, NSBH, and BBH events.

Figure 3 in Asymmetric acoustic signal recognition led to asymmetric gene flow between two parapatric frogs
Figure 3. Acoustic response of Buergeria choui (blue) and B. otai (orange) against conspecific and heterospecific calls. Both species showed highest response against the calls from their own kind. However, the eastern and western populations of B. otai represent behavioral difference. The western population shows the strongest response to the 'chicken trills' (Type 2), which was unique for this species; whereas the eastern population response strongest to Type 1b, which is a shared 'cricket trills' similar to Type 1a produced by B. choui.
Figure 2. A, G in Asymmetric acoustic signal recognition led to asymmetric gene flow between two parapatric frogs
Figure 2. A, G-PHOCS estimates of effective population sizes, divergence times, and migration rates between two clades of Buergeria otai and B. choui. There were two significant migrations: one from the ancestors of B. otai to B. choui, and the recent one from B. choui to eastern B. otai. Gene flow estimated by MIGRATE-N (B) and δaδi (C) revealed congruent results, indicating the gene flow only occurred between B. choui and the eastern B. otai.
