Promoting equity in scientific recommendations for high seas governance
Published: 2021-02-14
Subjects: Biodiversity, Life Sciences
In the coming months, international negotiations under the 1982 United Nations Convention on the Law of the Sea (UNCLOS) will enter their fourth and final session to establish a legally binding agreement for the conservation and sustainable use of marine biodiversity in one of our largest global commons, areas beyond national jurisdiction (BBNJ). In this context, scientists have proposed [...]
Lessons from a century of conservation translocations
Published: 2021-02-12
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Translocation—moving individuals for release in different locations—is among the most important conservation interventions for increasing or re-establishing populations of threatened species. However, translocations often fail. To improve their effectiveness, we need to understand the features that distinguish successful from failed translocations. Here, we assembled and analysed a global [...]
Oases in the Sahara Desert – Linking Biological and Cultural Diversity
Published: 2021-02-11
Subjects: Biodiversity, Life Sciences
The diversity of life sensu lato comprises both biological and cultural diversity, described as “biocultural diversity”. Similar to plant and animal species, cultures and languages are threatened by extinction, too. Since drylands are pivotal systems for nature and people alike, we use oases in the Sahara Desert as model systems for examining patterns and trends of biocultural diversity. We [...]
CEUTA snowy plover open access data - COMMENTARY

Subjects: Behavior and Ethology, Biodiversity, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Population Biology
Eberhart-Phillips et al. (2020, Scientific Data 7: 149) recently published a data-paper CeutaOPEN. However, the publication has significant shortcomings: the article does not explain the history nor the context of the project, it did not give credit to the developers of field methodology and data structure, and fails to acknowledge key contributions to the project. We request correcting these [...]
Thermal flexibility and a generalist life history promote urban tolerance in butterflies
Published: 2021-02-08
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Urban expansion poses a serious threat to biodiversity. Given that the expected area of urban land cover is predicted to increase by 2-3 million km2 by 2050, urban environments are one of the most widespread human-dominated land-uses affecting biodiversity. Responses to urbanization differ greatly among species. Some species are unable to tolerate urban environments (i.e., urban avoiders), others [...]
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 [...]
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

Subjects: Biodiversity, Life Sciences
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 [...]
Reptile smuggling is predicted by trends in the legal exotic pet trade
Published: 2021-01-28
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: 2021-01-26
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 [...]
Set theory and types of groups in phylogenetics
Published: 2021-01-26
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 [...]
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 [...]

Challenges and opportunities of species distribution modelling of terrestrial arthropod predators
Published: 2020-12-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences
Species distribution models (SDMs) are emerging as essential tools in the equipment of many ecologists; they are useful in exploring species distributions in space and time and in answering an assortment of questions related to historical biogeography, climate change biology and conservation biology. Given that arthropod distributions are strongly influenced by microclimatic conditions and [...]
Beta and phylogenetic diversities tell complementary stories about ecological networks biogeography
Published: 2020-12-11
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
The beta-diversity of interactions between communities does not necessarily correspond to the differences related to their species composition because interactions show greater variability than species co-occurrence. Additionally, the structure of species interaction networks can itself vary over spatial gradients, thereby adding constraints on the dissimilarity of communities in space. We used [...]
