Data from: Phylogenomic analyses of the Photinia complex support the recognition of a new genus Phippsiomeles and the resurrection of a redefined Stranvaesia in Maleae (Rosaceae)
Photinia and its morphologically similar allies in Maleae (Rosaceae) consist of five currently recognized genera: Aronia, Heteromeles, Photinia, Pourthiaea, and Stranvaesia, and 68 species, distributed in Asia and North & Central America. Despite previous efforts to clarify relationships in this group, the generic delimitations have remained uncertain. Our goals were to reconstruct a robust phylogeny of Photinia and its close allies to test the monophyly of the currently recognized genera, especially Photinia and Stranvaesia, and the hybrid origin hypothesis of Photinia bodinieri. This study employs complete plastomes and the entire nrDNA assembled from the genome skimming approach with a broad taxon sampling of 81 species in 30 genera of Rosaceae, especially Maleae. Based on three datasets, including the whole plastome (WP), coding sequence (CDS) and nrDNA repeats, the results of Maximum likelihood (ML) and Bayesian analyses (BI) showed that Stranvaesia and Photinia, as previously circumscribed, were each non-monophyletic. Six clades have been recovered herein within Photinia and its allied genera: Aronia, Heteromeles, Photinia s.s., Pourthiaea, Stranvaesia, and a new genus Phippsiomeles consisting of the Central American species formerly placed in Photinia. The strong conflicts between the plastome and nrDNA phylogenies of Phippsiomeles and Stranvaesia tomentosa suggest the possibility that they may have each originated involving hybridization events, while no incongruence among datasets was detected to support the hybrid origin of Photinia bodinieri. We provide 12 new combinations, to transfer eight taxa of the New World Photinia into Phippsiomeles and clarify the generic placements of several species of Photinia and Stranvaesia.
A resurrection study reveals limited evolution of phenology in response to recent climate change across the geographic range of the scarlet monkeyflower
<p>Premise of the study: As global climate change alters drought regimes, rapid evolution of traits that facilitate adaptation to drought can rescue populations in decline. The evolution of phenological advancement can allow plants to escape drought, but evolutionary responses in phenology can vary across a species' range due to differences in drought intensity and standing genetic variation.</p> <p>Methods: <em>Mimulus cardinalis</em>, a perennial herb spanning a broad climatic gradient, recently experienced a period of record drought. Here, we used a resurrection study comparing flowering time and stem height at first flower of pre-drought ancestors and post-drought descendants from northern-edge, central, and southern-edge populations in a common environment to examine the evolution of drought escape traits across the latitudinal range.</p> <p>Key results: Contrary to the hypothesis of the evolution of advanced phenology in response to recent drought, flowering time did not advance between ancestors and descendants in any population, though storage condition and maternal effects could have impacted these results. Stem height was positively correlated with flowering time, such that plants that flowered earlier were shorter at first flower. This correlation could constrain the evolution of earlier flowering time if selection favors flowering early at a large size.</p> <p>Conclusions: These findings suggest that rapid evolution of phenology will not rescue these populations from recent climate change. Future work is needed to examine the potential for the evolution of alternative drought strategies and phenotypic plasticity to buffer <em>M. cardinalis</em> populations from changing climate.</p>
Data from: Description of a new species of Petrolisthes in the Indo-West Pacific with a redefinition of P. hastatus Stimpson, 1858 and resurrection of P. inermis (Heller, 1862) (Crustacea, Anomura, Porcellanidae)
The porcellanid crab Petrolisthes hastatus Stimpson, 1858, has been traditionally viewed as a highly variable species with a wide distribution in the West Pacific. For more than a century there has been taxonomic confusion of this species with morphologically similar taxa, some of which were synonymized with Stimpson's taxon. We redefine P. hastatus, resurrect P. inermis as a valid species, discuss the status of P. tenkatei De Man, 1893, and describe a new species as P. elegantissimus from Indonesia.
Data from: Resurrecting an extinct salmon evolutionarily significant unit: archived scales, historical DNA, and implications for restoration
Archival scales from 603 sockeye salmon (Oncorhynchus nerka), sampled from May to July 1924 in the lower Columbia River, were analyzed for genetic variability at 12 microsatellite loci, and compared to 17 present-day O. nerka populations—exhibiting either anadromous (sockeye salmon) or non-anadromous (kokanee) life histories—from throughout the Columbia River Basin, including areas upstream of impassable dams built subsequent to 1924. Statistical analyses identified four major genetic assemblages of sockeye salmon in the 1924 samples. Two of these putative historical groupings were found to be genetically similar to extant evolutionarily significant units (ESUs) in the Okanogan and Wenatchee rivers (pairwise FST = 0.004 and 0.002, respectively) and assignment tests were able to allocate 77% of the fish in these two historical groupings to the contemporary Okanogan River and Lake Wenatchee ESUs. A third historical genetic grouping was most closely aligned with contemporary sockeye salmon in Redfish Lake, Idaho, although the association was less robust (pairwise FST = 0.060). However, a fourth genetic grouping did not appear to be related to any contemporary sockeye salmon or kokanee population, assigned poorly to the O. nerka baseline, and had distinctive early return migration-timing suggesting that this group represented a putative historical ESU originating in headwater lakes in British Columbia that was likely extirpated sometime after 1924. The lack of a contemporary O. nerka population possessing the genetic legacy of this extinct ESU indicates that efforts to reestablish early-migrating sockeye salmon to the headwater lakes region of the Columbia River will be difficult.
Data from: Thermal evolution offsets the elevated toxicity of a contaminant under warming: a resurrection study in Daphnia magna
Synergistic interactions between temperature and contaminants are a major challenge for ecological risk assessment, especially under global warming. While thermal evolution may increase the ability to deal with warming, it is unknown whether it may also affect the ability to deal with the many contaminants that are more toxic at higher temperatures. We investigated how evolution of genetic adaptation to warming affected the interactions between warming and a novel stressor: zinc oxide nanoparticles (nZnO) in a natural population of Daphnia magna using resurrection ecology. We hatched resting eggs from two D. magna subpopulations (old: 1955-1965, recent: 1995-2005) from the sediment of a lake that experienced an increase in average temperature and in recurrence of heat waves but was never exposed to industrial waste. In the old 'ancestral' subpopulation, exposure to a sublethal concentration of nZnO decreased the intrinsic growth rate, metabolic activity and energy reserves at 24°C but not at 20°C, indicating a synergism between warming and nZnO. In contrast, these synergistic effects disappeared in the recent 'derived' subpopulation that evolved a lower sensitivity to nZnO at 24°C, which indicates that thermal evolution could offset the elevated toxicity of nZnO under warming. This evolution of reduced sensitivity to nZnO under warming could not be explained by changes in the total internal zinc accumulation but was partially associated with the evolution of the expression of a key metal detoxification gene under warming. Our results suggest that the increased sensitivity to the sublethal concentration of nZnO under the predicted 4°C warming by the end of this century may be counteracted by thermal evolution in this D. magna population. Our results illustrate the importance of evolution to warming in shaping the responses to another anthropogenic stressor, here a contaminant. More general, genetic adaptation to an environmental stressor may ensure that synergistic effects between contaminants and this environmental stressor will not be present anymore.
Data from: Maladaptation to acute metal exposure in resurrected Daphnia ambigua clones after decades of increasing contamination
Human environmental impacts have driven some of the strongest and fastest phenotypic changes recorded in wild animal populations. Across populations, this variation is often adaptive, as populations evolve fitness advantages in response to human-modified environments. Yet some populations fail to adapt to changing environments. Evidenced by declines in relative fitness, such seemingly maladaptive outcomes are less common, but may be more likely in human modified contexts. Further, our ability to investigate the dynamics of these adaptive and maladaptive responses over time is typically limited in natural systems. I combined resurrection ecology and paleolimnology approaches to examine evolutionary responses of the freshwater zooplankter Daphnia to exposure to heavy metal contamination over the past 50-75 years using animals hatched from diapausing egg banks. In contrast to the predicted trend of adaptation to metal exposure over time, I observed an increase in sensitivity to both copper and cadmium exposure associated with increasing historic contamination. This potentially maladaptive trend occurred in Daphnia populations in three lakes. Given that the release of toxicants such as heavy metals is widespread and other researchers have observed local maladaptation to toxicant exposure, it is important to understand the drivers and implications of this pattern.
Data from: Resurrection of the island rule - human-driven extinctions have obscured a basic evolutionary pattern
Islands are or have been occupied by unusual species, such as dwarf proboscideans and giant rodents. The discussion of the classical, but controversial "island rule," which states that mammalian body sizes converge on intermediate sizes on islands, has been stimulated by these unusual species. In this study, we use an unprecedented global data set of the distributions and body sizes of late-Quaternary mammal species and a novel analytical method to analyze body size evolution on islands. The analyses produced strong support for the island rule. Islands have suffered massive human-driven losses of species, and we found that the support for the island rule was substantially stronger when the many late-Quaternary extinct species were also considered (particularly, the tendency for dwarfing in large taxa). The decisive support for the island rule in this study confirms that evolution plays out markedly different on islands and that human impact may obscure even fundamental evolutionary patterns.
Data from: Resurrection ecology in Artemia
Resurrection Ecology (RE) is a very powerful approach to address a wide range of question in ecology and evolution. This approach rests on using appropriate model systems, and only few are known to be available. In this paper, we show that Artemia has multiple attractive features (short generation time, cyst bank and collections, well documented phylogeography and ecology) for a good RE model. We show in detail with a case study how cysts can be recovered from sediments to document the history and dynamics of a biological invasion. We finally discuss with precise examples the many RE possibilities with this model system: adaptation to climate change, to pollution, to parasites, to invaders and evolution of reproductive systems.
