Chemistry and Chaos: A Role-Playing Game for Teaching Chemistry
(ACS, 2023-05) Mendez, J. D.; IUC Division of Science
Chemistry and Chaos is a role-playing game that was developed to teach a wide variety of chemistry topics. The game uses the traditional role-playing framework to present material in an engaging and interactive format. The students take on the role of a particular type of chemist while the instructor guides them on an adventure to test their chemistry knowledge. Overwhelmingly positive responses show that students were engaged in the activity and also self-identified learning gains.

Correction to: Inaugural BMC Ecology and Evolution image competition: the winning images
(Springer Nature, 2021-09-09) Harman, Jennifer L.; Cuff, Alison L.; Settele, Josef; Jacobus, Luke M.; Liberles, David A.; Traulsen, Arne; IUPUC Division of Science
Following the publication of the original article [1], we were notified that: The description of Fig. 2 was incorrect: This image shows "an amphipod crustacean of the species E. verrucosus densely covered with an overgrown colony of parasitic ciliates. Ciliates living on weakened crustaceans are capable of forming vast colonies resembling a "fur coat" Should read: This image shows "an amphipod crustacean of the species E. verrucosus densely covered with an overgrown colony of parasitic ciliates and unknown oomycetes or fungi. These organisms on weakened crustaceans are capable of forming vast colonies resembling a "fur coat". The caption of Fig. 2 was changed from “Eulimnogammarus verrucosus, a species of crustacean endemic to the UNESCO World Heritage Site Lake Baikal, suffering from a parasitic ciliate infection. Attribution: Kseniya Vereshchagina” to “Eulimnogammarus verrucosus, a species of crustacean endemic to the UNESCO World Heritage Site Lake Baikal, suffering from a parasitic ciliate and unknown oomycete (water mold) or fungi infection. Attribution: Kseniya Vereshchagina”. The affiliations of the 3rd and 4th authors had been swapped by mistake. The original article has been corrected.

In 2022, researchers from around the world entered the BMC Ecology and Evolution photography competition. The contest produced a spectacular collection of photographs that capture the wonder of the natural world and the growing need to protect it as the human impact on the planet intensifies. This editorial celebrates the winning images selected by the Editor of BMC Ecology and Evolution and senior members of the journal's editorial board.
Mayfly taxonomy (Arthropoda: Hexapoda: Ephemeroptera) during the first two decades of the twenty-first century and the concentration of taxonomic publishing
(Magnolia Press, 2021) Jacobus, Luke M.; Salles, Frederico F.; Price, Ben; Pereira-Da-Conceicoa, Lyndall; Dominguez, Eduardo; Suter, P. J.; Molineri, Carlos; Tiunova, Tatyana M.; Sartori, M.; IUPUC Division of Science
The twentieth anniversary of the first issue of Zootaxa (De Moraes & Freire, 2001) provides an appropriate opportunity to reflect on some trends in global Ephemeroptera taxonomy publishing over the last two decades, with a focus on the description of new species and the outsized role of the journals Zootaxa and ZooKeys, in particular. Detailed reviews of world Ephemeroptera knowledge up to about 2000 were collected in a series of nine papers from a symposium on the subject, published together in the proceedings of the ninth International Conference on Ephemeroptera (Domínguez 2001). Domínguez & Dos Santos (2014) provided updates and analysis for South America up to the year 2012. More recent detailed accounts of regional and taxonomic diversity, and other aspects of mayfly biology and ecology, were reviewed by Jacobus et al. (2019), while Ogden et al. (2019) discussed current issues involving higher classification.
A Review of the Genus Serratella Edmunds, 1959 in China with Description of a New Species (Ephemeroptera: Ephemerellidae)
(MDPI, 2022-11-04) Ding , Manqing; Jacobus, Luke M.; Zhou , Changfa; IUPUC Division of Science
Species in the genus Serratella Edmunds, 1959 from China have never been compared and photographed systematically. Six valid Chinese Serratella species are recognized and revised in this paper. Among them, the imagos of S. brevicauda Jacobus et al., 2009 are unknown; the nymph of this species has a stout, strong body, with remarkably short caudal filaments and maxillary palpi. In contrast, only the imago stage of Serratella fusongensis (Su and You, 1988) (=Serratella longipennis Zhou et al., 1997, syn. nov.) is known; it has relatively long penes with small dorsal projections. The nymphs of S. setigera Bajkova, 1967 have small abdominal tergal spines but distinct, stout, blunt bristles on the spines, and the apexes of the male penes are round and shallowly divided. The fourth species, S. acutiformis sp. nov., which was collected from Western China, has sharp penial apexes (imagos) and large abdominal spines (nymphs). Unlike the former four species, S. ignita (Poda, 1761) and S. zapekinae Bajkova, 1967 has sub-quadrate penes without prominent dorsal projections. The nymph of S. ignita has lateral hair-like setae on the caudal filaments, while the nymph of S. zapekinae lacks such setae but has pairs of tubercles on the head and pronotum. Some characters used in the generic delineation of the genera Ephemerella Walsh, 1862 and Serratella, such as nymphal maxillary palpi and hair-like setae on caudal filaments as well as features of the imaginal penes and forelegs, are varied in Chinese species. However, all species in this paper have bifurcate ventral lamellae of gill VI. Our work highlights a need for further comparative systematic study of the genera Serratella, Ephemerella, and another related genus Torleya Lestage, 1917.
A new species of Notacanthella Jacobus & McCafferty, 2008 (Ephemeroptera, Ephemerellidae) from Yunnan, China
(Pensoft, 2022) Li, Xian-Fu; Sun, Ye-Kang; Liu, Zi-Ye; Jacobus, Luke M.; Xiao, Wen; IUPUC Division of Science
Notacanthella jinwu Li & Jacobus, sp. nov. is described based on egg, nymph, and winged stages from Dali Bai Autonomous Prefecture, Yunnan Province, China. The nymph of the new species is closely related to N. commodema (Allen, 1971), whose nymphs share a similar tuberculation of head, pronotum, and mesonotum. However, the nymph of our new species can be distinguished based on the structures of male sternum IX and abdominal tergal tubercles. In addition, the new species is distributed in subtropical high-altitude areas. The description of the male imago of the new species is the first certain one for the genus Notacanthella. Data associated with our new species allow for expanded discussion and diagnosis of Notacanthella and closely related genera. An identification key for nymphs of these groups is provided.

Associations between infant–mother physiological synchrony and 4- and 6-month-old infants’ emotion regulation
(Wiley, 2021-09) Abney, Drew H.; daSilva, Elizabeth B.; Bertenthal, Bennet I.; IUPUC Division of Science
In this study we assessed whether physiological synchrony between infants and mothers contributes to infants’ emotion regulation following a mild social stressor. Infants between 4 and 6 months of age and their mothers were tested in the face-to-face-still-face paradigm and were assessed for behavioral and physiological self-regulation during and following the stressor. Physiological synchrony was calculated from a continuous measure of respiratory sinus arrhythmia (RSA) enabling us to cross-correlate the infants’ and mothers’ RSA responses. Without considering physiological synchrony, the evidence suggested that infants’ distress followed the prototypical pattern of increasing during the Still Face episode and then decreasing during the reunion episode. Once physiological synchrony was added to the model, we observed that infants’ emotion regulation improved if mother–infant synchrony was positive, but not if it was negative. This result was qualified further by whether or not infants suppressed their RSA response during the Still Face episode. In sum, these findings highlight how individual differences in infants’ physiological responses contribute significantly to their self-regulation abilities.
