Summary Wildlife is an essential component of all ecosystems. Most places in the globe do not have local, timely information on which species are present or how their populations changing. With arrival new technologies, camera traps become a popular way to collect wildlife data. However, data collection has increased at much faster rate than development tools manage, process and analyse these Without tools, managers other stakeholders little effectively understand monitor populations. We...
Ecological “big data” Human activities are rapidly altering the natural world. Nowhere is this more evident, perhaps, than in Arctic, yet region remains one of most remote and difficult to study. Researchers have increasingly relied on animal tracking data these regions understand individual species' responses, but if we want larger-scale change, need integrate our understanding across species. Davidson et al. introduce an open-source archive that currently hosts 15 million location points...
Conserving and managing biodiversity in the face of ongoing global change requires sufficient evidence to assess status trends species distributions. Here, we propose novel indicators data coverage sampling effectiveness analyze national trajectories closing spatiotemporal knowledge gaps for terrestrial vertebrates (1950 2019). Despite a rapid rise coverage, particularly last 2 decades, strong geographic taxonomic biases persist. For some taxa regions, tremendous growth records failed...
Growing threats to biodiversity demand timely, detailed information on species occurrence, diversity and abundance at large scales. Camera traps (CTs), combined with computer vision models, provide an efficient method survey of certain taxa high spatio-temporal resolution. We test the potential CTs close knowledge gaps by comparing CT records terrestrial mammals birds from recently released Wildlife Insights platform publicly available occurrences many observation types in Global...
Soundscape-level acoustic recordings revealed delay in arrival of songbird community to arctic breeding grounds.
Mobile devices, and other tracking technologies, generate detailed data on the movements behavior of billions people worldwide. At present, these are predominantly used to pursue corporate interests. We argue that improving access human-mobility is essential for addressing urgent conservation sustainability goals. Close collaboration between industry research community has potential substantive environmental societal benefits.
Abstract The geographic redistributions of species due to a rapidly changing climate are poised perturb ecological communities and significantly impact ecosystems human livelihoods. Effectively managing these biological impacts requires thorough understanding the patterns processes range shifts. While substantial recent have been identified recognized vary by taxon, region, geometry, there large gaps biases in available evidence. Here, we use largest compilation change observations date,...
Movement is a key means by which animals cope with variable environments. As they move, construct individual niches composed of the environmental conditions experience. Niche axes may vary over time and covary one another as make tradeoffs between competing needs. Seasonal migration expected to produce substantial niche variation move keep pace major life history phases fluctuations in conditions. Here, we apply time-ordered principal component analysis examine dynamic variance covariance...
Abstract Migratory birds have the capacity to shift their migration phenology in response climatic change. Yet mechanistic underpinning of changes migratory timing remain poorly understood. We employed newly developed global positioning system (GPS) tracking devices and long-term dataset passage investigate how behavioral responses environmental conditions relate phenological shifts American robins ( Turdus migratorius ) during spring Arctic-boreal breeding grounds. found that over past...
Abstract Over the past five decades, a large number of wild animals have been individually identified by various observation systems and/or temporary tracking methods, providing unparalleled insights into their lives over both time and space. However, so far there is no comprehensive record uniquely nor where data metadata are stored, for example photos, physiological genetic samples, disease screens, information on social relationships. Databases currently do not offer unique identifiers...
As global climatic changes increase plant susceptibility to large-scale disturbances such as drought and pathogens, understory responses these will become increasingly important long-term forest dynamics. To better understand canopy disturbance, we measured in the growth physiology of dominant shrub, American witch-hazel (Hamamelis virginiana L.), response girdling oaks a temperate hardwood northeastern United States. Changes H. may be regeneration forests, this common shrub largely shapes...
Camera traps have existed since the 1890s (Kucera and Barrett 2011), but they weren’t widely used until introduction of commercial infrared-triggered cameras in early 1990s (Meek et al. 2014). Since then, millions, perhaps billions camera trap images been collected for many reasons, biodiversity monitoring being one key applications. Unfortunately, although there are deployments all over world, these operations occur isolation, limiting impact could on a global understanding health. Even...
Abstract The general public and scientific community alike are abuzz over the release of ChatGPT GPT-4. Among many concerns being raised about emergence widespread use tools based on large language models (LLMs) is potential for them to propagate biases inequities. We hope open a conversation within environmental data science encourage circumspect responsible LLMs. Here, we pose series questions aimed at fostering discussion initiating larger dialogue. To improve literacy these tools,...
Abstract Conserving and managing biodiversity in the face of ongoing global change requires sufficient evidence to assess status trends species distributions. Here we analyze national trajectories closing spatiotemporal knowledge gaps for terrestrial vertebrates (1950-2019) based on novel indicators data coverage sampling effectiveness. Despite a rapid rise coverage, particularly last two decades, strong geographic taxonomic biases persist. For some taxa regions, tremendous growth records...
A recent theme issue of *Phil Trans B* addressed the multifaceted problems tracking biodiversity change to meet emerging international development goals, national economic accounting, and diverse community interests. The results place science in context policy needs, provide an updated roadmap for how acquire, process, use observation data a changing world. In this seminar, several authors will speak about their work. Theory application improved species richness estimator Species is...
