Large-bodied birds are over-represented in unstructured citizen science data
Published: 2021-03-05
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Citizen science platforms are quickly accumulating hundreds of millions of biodiversity observations around the world annually. Quantifying and correcting for the biases in citizen science datasets remains an important first step before these data are used to address ecological questions and monitor biodiversity. One source of potential bias among datasets is the difference between those citizen [...]
Wildlife gardening: an urban nexus of social and ecological relationships
Published: 2021-03-05
Subjects: Biodiversity, Environmental Studies, Life Sciences, Social and Behavioral Sciences
Biodiversity in urban environments continues to decline, alongside diminution of human connections with nature and community. An integrated ethic and practice of caring for one’s human and ecological community could help address these issues. Here, we describe how wildlife gardening can be such a pathway. We snapshot related social dynamics and human wellbeing benefits, highlighting a case study [...]
Towards monitoring ecosystem integrity within the Post-2020 Global Biodiversity Framework
Published: 2021-03-04
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Signatory countries to the Convention on Biological Diversity (CBD) are formulating indicators through 2030 under the post-2020 Global Biodiversity Framework (GBF). These goals include increasing the integrity of natural ecosystems. However, the definition of integrity and methods for measuring it remain unspecified. Moreover, nations did not achieve their 2011-2020 CBD targets, partly due to [...]
A Global Agenda for Advancing Freshwater Biodiversity Research
Published: 2021-02-23
Subjects: Biodiversity, Life Sciences
Global freshwater biodiversity is declining dramatically, and meeting the challenges of this crisis requires bold goals and the mobilization of substantial resources. While the reasons are varied, investments in both research and conservation of freshwater biodiversity lag far behind those in the terrestrial and marine realms. Inspired by a global consultation, we identify 15 pressing priority [...]
Fading opportunities for mitigating agriculture-environment trade-offs in a South American deforestation hotspot
Published: 2021-02-19
Subjects: Biodiversity, Life Sciences
Strong trade-offs between agriculture and the environment occur in deforestation frontiers, particularly in the world’s rapidly disappearing tropical and subtropical dry forests. Pathways to mitigate these trade-offs are often unclear, as well as how deforestation or different policies alter the option space of available pathways. Using a spatial optimization framework based on linear [...]
Text classification to streamline online wildlife trade analyses
Published: 2021-02-18
Subjects: Biodiversity, Life Sciences
1. Automated monitoring of websites that trade wildlife is increasingly necessary to inform conservation and biosecurity efforts. However, e-commerce and wildlife trading websites can contain a vast number of advertisements, an unknown proportion of which may be irrelevant to researchers and practitioners. Given that many of these advertisements have an unstructured text format, automated [...]
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
Published: 2021-02-11
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

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 [...]
