Urban tolerance of birds changes throughout the full annual cycle
Published: 2021-02-08
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Aim: Our objective was to quantify urban tolerance for North American birds across the full annual cycle. We tested (1) whether intra-annual variability of urban tolerance differed between migrants and residents and (2) whether intra-annual variability of urban tolerance was phylogenetically conserved. We then assessed how the relationship between ecological and life history traits and urban [...]
Male size and reproductive performance in three species of livebearing fishes (Gambusia spp.): a systematic review and meta-analysis
Published: 2021-02-06
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
1. The genus Gambusia represents approximately 45 species of polyandrous livebearing fishes with reversed sexual size dimorphism (i.e. males smaller than females) and with copulation predominantly via male coercion. Male body size has been suggested as an important sexually selected trait, but despite abundant research, evidence for sexual selection on male body size in this genus is mixed. 2. [...]
Corrections to Phytologia,vol. 102 (3) – Rumicastrum dielsii (Poelln.) Carolin is an “alien,” R. cylindricum (Poelln.) Carolin is Elatinaceae, R. monogynum (Poelln.) Carolin is incertae sedis, and the combination in Rumicastrum for Talinum nanum Nees was neglected

In Phytologia 102 (4): 116–123, Hershkovitz recombined into Rumicastrum Ulbrich 65 Australian Montiaceae species originally classified in Calandrinia Kunth. Three of these species, all described by Karl von Poellnitz, do not pertain to Rumicastrum. The type specimen of Rumicastrum dielsii (Poelln.) Carolin is Calandrinia menziesii (Hook.) Torr. & A.Gray, a western North American species [...]
A 25-years population dynamics of sika deer in Kyushu Island, Japan: Estimation using vector autoregressive spatiotemporal model and evaluation of a large-scale management
Published: 2021-02-04
Subjects: Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences, Population Biology
Regional management of large herbivore populations is known to be effective in reducing local economic damages and conserving local endemic plants. However, herbivores often move across management areas, and the effect of population management on a large spatial scale is poorly understood, even though it is necessary to use a large-scale approach across multiple management units to implement [...]
The Ecology of Sleep in Reptiles
Published: 2021-02-03
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Sleep is ubiquitous in the animal kingdom and yet displays considerable variation in its extent and form in the wild. Ecological factors, such as predation, competition, and microclimate, therefore, are likely to play a strong role in shaping characteristics of sleep. Despite the potential for ecological factors to influence various aspects of sleep, the ecological context of sleep in reptiles [...]
The diversity of plant sex chromosomes highlighted through advances in genome sequencing
Published: 2021-01-30
Subjects: Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
For centuries scientists have been intrigued by the origin of dioecy in plants, characterizing sex-specific development, uncovering cytological differences between the sexes, and developing theoretical models. However, through the invention and continued improvements in genomic technologies, we have truly begun to unlock the genetic basis of dioecy in many species. Here we broadly review the [...]
Systematic review protocol to guide the delineation of critical habitat in the riparian zone for listed freshwater fishes and mussels
Published: 2021-01-30
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Background Habitat that is necessary for the survival and recovery of a species listed as threatened, endangered, or extirpated (i.e., Critical Habitat) is protected in Canada. For aquatic species, Critical Habitat may include riparian habitat, however it is unclear how much of this riparian habitat needs to be protected to support the survival and recovery of a listed species (primary question). [...]
Reptile smuggling is predicted by trends in the legal exotic pet trade
Published: 2021-01-29
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Western countries are less frequently implicated in illegal wildlife trade (IWT), contrasted with other transnational consumers, yet substantial evidence suggests that they contribute prominently. Live animal smuggling presents a suite of biosecurity concerns, including invasive species and disease risks. Here, we compared the live alien reptile species smuggled to Australia (75 species) to the [...]
Soil fungal diversity and community assembly: Affected by island size or type?
Published: 2021-01-27
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences, Microbiology, Terrestrial and Aquatic Ecology
Fungi have huge biodiversity and play important roles in soil biogeochemical cycling and ecosystem services in island ecosystems. Although island biogeography has been widely studied in macroorganisms, the relationship between soil fungal diversity and area in islands is less documented. Here, we examine soil fungal communities of 18 oceanic islands belonged to two types of islands (8 general [...]
Evolutionary Pathways and Trajectories in Antibiotic Resistance
Published: 2021-01-27
Subjects: Life Sciences, Medicine and Health Sciences, Microbiology, Pathogenic Microbiology
Evolution is the hallmark of life. Descriptions of the evolution of microorganisms have provided a wealth of information, but knowledge regarding “what happened” has precluded a deeper understanding of “how” evolution has proceeded, as in the case of antimicrobial resistance. The difficulty in answering the “how” question lies in the multihierarchical dimensions of evolutionary processes, nested [...]
Set theory and types of groups in phylogenetics
Published: 2021-01-27
Subjects: Biodiversity, Ecology and Evolutionary Biology, Evolution, Life Sciences
Mathematically, it is possible to be a subset (⊂) of a set and not to be its member (∈)—e.g. the empty set. Here, I highlight that a similar principle applies to undiscovered objects in sets of real objects. The current definitions of holophyly (monophyly sensu stricto) and paraphyly suggest a direct membership (∈) of ancestors in taxa. These ancestors are almost always unknown (undiscovered) in [...]
Multi-replicated enrichment communities as a model system in microbial ecology
Published: 2021-01-25
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology
Recent advances in robotics and affordable genomic sequencing technologies have made it possible to establish and quantitatively track the assembly of enrichment communities in high-throughput. By conducting community assembly experiments in up to thousands of synthetic habitats, where the extrinsic sources of variation among replicates can be controlled, we can now study the reproducibility and [...]
Consistent replacement of small- by large-ranged plant species across habitats
Published: 2021-01-25
Subjects: Biodiversity, Life Sciences
The direction and magnitude of long-term changes in local plant species richness are highly variable among studies, while species turnover is ubiquitous. However, it is unknown whether the nature of species turnover is idiosyncratic or whether certain types of species are consistently gained or lost across different habitats. To address this question, we analyzed the trajectories of 1,827 [...]
Complex environments alter competitive dynamics in fungi
Published: 2021-01-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Competition is a key biotic factor that often structures natural communities. Many attempts to disentangle how competition shapes natural communities have relied on experiments on simplified systems or through simple mathematical models. But these simplified approaches are limited in their ability to represent the complexity seen in more natural settings. Here, we considered the competitive [...]
Raczka et al. Interactions between microbial diversity and substrate chemistry determine the fate of carbon in soil.
Published: 2021-01-20
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Microbial decomposition drives the transformation of plant-derived substrates into microbial products that form stable soil organic matter (SOM). Recent theories have posited that decomposition depends on an interaction between SOM chemistry with microbial diversity and resulting function. Here, we explicitly test these theories by coupling quantitative stable isotope probing and metabolomics to [...]
