Breaking the Ice: A Review of Phages in Polar Ecosystems
Published: 2023-05-28
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Microbiology
Bacteriophages, or phages, are viruses that infect and replicate within bacterial hosts, playing a significant role in regulating microbial populations and ecosystem dynamics. However, phages from extreme environments such as polar regions remain relatively understudied due to challenges like restricted ecosystem access and low biomass. Understanding the diversity, structure, and functions of [...]
A Perspective on Conservation and Development
Published: 2023-05-25
Subjects: Biodiversity, Community-based Research, Demography, Population, and Ecology, Environmental Studies, Geography, Nature and Society Relations, Physical and Environmental Geography
Since the industrial revolution, the predominant model of economic development has involved economies of scale and unsustainable exploitation of natural resources, leading to environmental degradation and the ongoing mass extinction of species. The environmental impacts of this development-for(the sake of)-development model led to biodiversity conservation efforts that can be described as [...]
Biodiversity promotes resistance but dominant species shape recovery of grasslands under extreme drought
Published: 2023-05-18
Subjects: Biodiversity, Climate, Life Sciences
1. How biodiversity underpins ecosystem resistance (i.e., ability to withstand environmental perturbations) and recovery (i.e., ability to return to a pre-perturbation state) and thus stability under extreme climatic events is a timely question in ecology. To date, most studies have focused on the role of taxonomic diversity, neglecting how community functional composition and diversity beget [...]
Social media records hold valuable information for conservation planning
Published: 2023-05-11
Subjects: Biodiversity, Ecology and Evolutionary Biology
Citizen science plays a crucial role in helping monitor biodiversity and inform conservation. With the widespread use of smartphones, many people share biodiversity information on social media, but this information is still not widely used in conservation. Here, focussing on Bangladesh - a tropical mega-diverse and mega-populated country, we examine the potential importance of social media [...]
Improving ecological connectivity assessments with transfer learning and function approximation

This is a conference paper presented at the ICLR 2023 "Machine Learning for Remote Sensing" workshop. Protecting and restoring ecological connectivity is essential to climate change adaptation, and necessary if species are to shift their geographic distributions to track their suitable climatic conditions over the coming century. Despite the increasing availability of near real-time and high [...]
Conservation macrogenetics
Published: 2023-04-27
Subjects: Biodiversity, Ecology and Evolutionary Biology
Genetic diversity is a core aspect of biodiversity that has been underrepresented in global conservation policy but is gaining rapidly increasing recognition. Conservation geneticists have traditionally focused on identifying, managing, and safeguarding the adaptive potential of specific populations or species. However, for almost all species, conservation relevant, population-level genetic data [...]
Repeated evolution of extreme locomotor performance independent of changes in extended phenotype use in spiders
Published: 2023-04-24
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Biology, Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Entomology, Evolution, Integrative Biology, Life Sciences, Zoology
Many animals utilize self-built structures – so-called extended phenotypes – to enhance body functions, such as thermoregulation, prey capture or defence. Yet, it is unclear whether the evolution of animal constructions supplements or substitutes body functions. Here, using Austral brown spiders, we explored if the evolutionary loss and gain of silken webs as extended prey capture devices [...]
Interspecific behavioural interference and range dynamics: current insights and future directions
Published: 2023-04-24
Subjects: Animal Sciences, Biodiversity, Ecology and Evolutionary Biology, Evolution, Life Sciences, Ornithology, Other Animal Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology, Zoology
Novel biotic interactions in shifting communities play a key role in determining the ability of species’ ranges to track suitable habitat. To date, the impact of biotic interactions on range dynamics have predominantly been studied in the context of interactions between different trophic levels or, to a lesser extent, exploitative competition between species of the same trophic level. Yet, both [...]
Navigating the science policy interface: A co-created mind-map for early career researchers

Subjects: Biodiversity, Environmental Education, Environmental Policy, Environmental Studies, Other Public Affairs, Public Policy and Public Administration, Scholarship of Teaching and Learning, Sustainability
The science-policy interface (SPI) is a complex space, in theory and practice, that sees the interaction of various actors and perspectives coming together to enable scientific knowledge to support decision-making. Early Career Researchers (ECRs) are increasingly interested in engaging with SPI, with the number of opportunities to do so increasing at national and international levels. However, [...]
Phenological sensitivity of climate across taxa and local habitats in a high-Arctic arthropod community
Published: 2023-04-15
Subjects: Biodiversity, Terrestrial and Aquatic Ecology
Arthropods respond to climate change by shifting their phenology in the spring and summer seasons. These phenological shifts are rarely uniform, and taxa show distinct variation in the direction and magnitude of phenological responses to climate drivers. To gain insights into the most climate-sensitive taxa and forecast the implications of climate change on community-wide activity and biotic [...]
Spatial factors overcome seasonality in increasing the consumption of allochthonous food resources by fishes from tropical lotic ecosystems
Published: 2023-03-15
Subjects: Biodiversity, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
1. In lotic ecosystems, it is expected higher availability of allochthonous food resources during floods and rainfall events, which may yield a higher consumption of these resources by consumers. However, both the allochthonous input in aquatic ecosystems and seasonality in environmental conditions are locally dependent, thus dietary responses of freshwater consumers to seasonality should also be [...]
A probabilistic approach to estimating timber harvest location
Published: 2023-02-22
Subjects: Biodiversity, Biostatistics, Forest Management, Other Forestry and Forest Sciences, Statistical Methodology, Statistical Models
Determining the harvest location of timber is crucial to enforcing international regulations designed to protect natural resources and to tackle illegal logging and associated trade in forest products. Stable Isotope Ratio Analysis (SIRA) can be used to verify claims of timber harvest location by matching levels of naturally-occurring stable isotopes within wood tissue to location-specific ratios [...]

Published: 2023-02-20
Subjects: Biodiversity, Communication, International and Intercultural Communication
Biodiversity is the foundation of our lives. Yet we destroy ecosystems and drive species to extinction. Human-induced biodiversity loss does not yet receive sufficient public attention, although biodiversity is fundamental for dealing with global environmental crises. Effective communication of biodiversity-related knowledge is challenging but crucial and should contribute to evidence-based [...]
The missing link: discerning true from false negatives when sampling species interaction networks
Published: 2023-01-19
Subjects: Applied Statistics, Biodiversity, Ecology and Evolutionary Biology, Environmental Monitoring
Ecosystems are composed of networks of interacting species. These interactions allow communities of species to persist through time through both neutral and adaptive processes. Despite their importance, a robust understanding of (and ability to predict and forecast) interactions among species remains elusive. This knowledge-gap is largely driven by a shortfall of data—although species occurrence [...]
