Waterborne conspecific cues enhance larval settlement in the invasive jellyfish Aurelia coeruleaNARA Subscribed
Gregarious settlement contributes to the formation of jellyfish polyp aggregations, but the mechanism by which larvae detect habitats with conspecifics is poorly understood. Here, we tested the hypothesis that Aurelia coerulea larvae settle gregariously by detecting organic compounds released into the water by polyps. First, we conducted choice experiments to confirm the preference of larvae for substrate with conspecifics and...
Predation by the Native Nudibranch Austraeolis ornata on the Introduced Jellyfish Aurelia coeruleaNARA Subscribed
Understanding how non‐native scyphozoan jellyfish interact with native communities provides insights into the ecological processes structuring their populations. Aurelia coerulea is a problematic invasive species, with no known predators of the polyp stage outside its native range. Austraeolis ornata is a potential predator of A. coerulea polyps, but little is known about its biology and ecology. Both species inhabit shallow c...
A new species of lepocreadiid, Opechonoides opisthoporus n. sp. , is described infecting 12 pomacentrid fish species from the Great Barrier Reef, Australia, with Abudefduf whitleyi Allen & Robertson as the type-host. This taxon differs from the only other known member of the genus, Opechonoides gure Yamaguti, 1940, in the sucker width ratio, cirrus-sac length, position of the testes, position of the pore of Laurer’s canal, and...
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop yield, as well as to anticipate changes in this service, develop predictions, and...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Collisions with buildings cause up to 1 billion bird fatalities annually in the United States and Canada. However, efforts to reduce collisions would benefit from studies conducted at large spatial scales across multiple study sites with standardized methods and consideration of species‐ and life‐history‐related variation and correlates of collisions. We addressed these research needs through coordinated collection of data on...
Enduring sustainability challenges requires a new model of collective leadership that embraces critical reflection, inclusivity and care. Leadership collectives can support a move in academia from metrics to merits, from a focus on career to care, and enact a shift from disciplinary to inter- and trans-disciplinary research. Academic organisations need to reorient their training programs, work ethics and reward systems to enco...
Shorter, warmer winters may inhibit production of ephyrae in a population of the moon jellyfish Aurelia auritaNARA Subscribed
Scyphozoan jellyfish blooms display high interannual variability in terms of timing of appearance and size of the bloom. To understand the causes of this variability, the conditions experienced by the polyps prior to the production of ephyrae in the spring were examined. Polyps reared from planula larvae of Aurelia aurita medusae collected from southern England (50°49′58.8; − 1°05′36.9) were incubated under orthogonal combinat...
Flawed citation practices facilitate the unsubstantiated perception of a global trend toward increased jellyfish bloomsNARA Subscribed
Speculation over a global rise in jellyfish populations has become widespread in the scientific literature, but until recently the purported ‘global increase’ had not been tested. Here we present a citation analysis of peer‐reviewed literature to track the evolution of the current perception of increases in jellyfish and identify key papers involved in its establishment. Trend statements and citation threads were reviewed and...
Gelatinous zooplankton biomass in the global oceans: geographic variation and environmental driversNARA Subscribed
Aim Scientific debate regarding the future trends, and subsequent ecological, biogeochemical and societal impacts, of gelatinous zooplankton ( GZ ) in a changing ocean is hampered by lack of a global baseline and an understanding of the causes of biogeographic patterns. We address this by using a new global database of GZ records to test hypotheses relating to environmental drivers of biogeographic variation in the multidecada...
