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.
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.
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.

Associations between acoustic features of maternal speech and infants’ emotion regulation following a social stressor
(Wiley, 2022-01) Kolacz, Jacek; daSilva, Elizabeth B.; Lewis, Gregory F.; Bertenthal, Bennett I.; Porges, Stephen W.; IUPUC Division of Science
Caregiver voices may provide cues to mobilize or calm infants. This study examined whether maternal prosody predicted changes in infants’ biobehavioral state after the still face, a stressor in which the mother withdraws and reinstates social engagement. Ninety-four dyads participated in the study (infant age 4–8 months). Infants’ heart rate and respiratory sinus arrhythmia (measuring cardiac vagal tone) were derived from an electrocardiogram (ECG). Infants’ behavioral distress was measured by negative vocalizations, facial expressions, and gaze aversion. Mothers’ vocalizations were measured via a composite of spectral analysis and spectro-temporal modulation using a two-dimensional fast Fourier transformation of the audio spectrogram. High values on the maternal prosody composite were associated with decreases in infants’ heart rate (β = −.26, 95% CI: [−0.46, −0.05]) and behavioral distress (β = −.23, 95% CI: [−0.42, −0.03]), and increases in cardiac vagal tone in infants whose vagal tone was low during the stressor (1 SD below mean β = .39, 95% CI: [0.06, 0.73]). High infant heart rate predicted increases in the maternal prosody composite (β = .18, 95% CI: [0.03, 0.33]). These results suggest specific vocal acoustic features of speech that are relevant for regulating infants’ biobehavioral state and demonstrate mother–infant bi-directional dynamics.
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.

Brief Report: Reduced Temporal-Central EEG Alpha Coherence During Joint Attention Perception in Adolescents with Autism Spectrum Disorder
(Springer, 2016-04) Jaime, Mark; McMahon, Camilla M.; Davidson, Bridget C.; Newell, Lisa C.; Mundy, Peter C.; Henderson, Heather A.; Science, IUPUI Columbus
Although prior studies have demonstrated reduced resting state EEG coherence in adults with autism spectrum disorder (ASD), no studies have explored the nature of EEG coherence during joint attention. We examined the EEG coherence of the joint attention network in adolescents with and without ASD during congruent and incongruent joint attention perception and an eyes-open resting condition. Across conditions, adolescents with ASD showed reduced right hemisphere temporal-central alpha coherence compared to typically developing adolescents. Greater right temporal-central alpha coherence during joint attention was positively associated with social cognitive performance in typical development but not in ASD. These results suggest that, in addition to a resting state, EEG coherence during joint attention perception is reduced in ASD.

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”. The affiliations of the 3rd and 4th authors had been swapped by mistake. The original article has been corrected.
Counseling Adolescents Aging Out of Foster Care: A Neglected and Underserved Population
(2021) Tertocha-Ubelhor, Taylor; Russ, Brian R.; IUPUC Division of Science
The high prevalence of youth aging out of the foster care system and the numerous poor outcomes they experience during the transition to emerging adulthood has been well documented. Although addressing the complex needs and concerns of this distinct population can be difficult, mental health counselors maintain the philosophical tenants and training strengths necessary to successfully serve youth aging out of foster care. This article aims to provide counselors with the historical context, developmental framework, and specific challenges needed to better understand this population, as well as suggested counseling implications to address their unique needs by reviewing relevant literature.
