Twenty years of dynamic occupancy models: a review of applications and look to the future
Published: 2024-10-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Monitoring, Natural Resources and Conservation
Understanding patterns of species occupancy across landscapes and throughout time is a long-standing objective of ecological research that has inspired the development of numerous quantitative modelling approaches. However, estimating occupancy can be a challenge, particularly when contending with issues like imperfect detection and shifting distributions. Dynamic occupancy models (DOMs) offer a [...]
Snow persistence influences vegetation metrics central to Arctic greening analyses
Published: 2024-07-20
Subjects: Environmental Monitoring
Satellite imagery is critical for understanding land-surface change in the rapidly warming Arctic. Since the 1980s, studies have found positive trends in the normalised difference vegetation index (NDVI) derived from satellite imagery over the Arctic - commonly referred to as ‘Arctic greening’ and assumed to represent increased vegetation productivity. However, greening analyses use satellite [...]
Making use of spatially biased variables in ecosystem condition accounting – a GIS based workflow
Published: 2024-06-06
Subjects: Ecology and Evolutionary Biology, Environmental Indicators and Impact Assessment, Environmental Monitoring
Ecosystem Condition Accounts (ECA) should reflect the integrity or quality of all nature inside the scope of the account, and therefore rely on spatially representative indicators for condition. All ECAs are subject to data constraints in some way. Therefore, being able to make use of spatially biased data sets would be very valuable. For national ECAs, modelling approaches can in some cases be [...]
Global metrics for terrestrial biodiversity

Subjects: Biodiversity, Environmental Indicators and Impact Assessment, Environmental Monitoring, Life Sciences, Natural Resources and Conservation
Biodiversity metrics are increasingly in demand for informing government, businesses, and civil society decisions. However, while there are many metrics available, it is not always clear to end-users how they differ or for what purpose they are best suited. This confusion undermines uptake. Here, we seek to clarify these questions by reviewing and presenting a database of 573 biodiversity-related [...]

Benthic macroinvertebrates are a frequently used indicator group for biomonitoring and biological assessment of river ecosystems. However, their taxonomic identification is laborious and requires special expertise. In this study, we aimed to assess the capability of a vision transformer (ViT) model for family-level identification of mayflies (order Ephemeroptera). Specifically, we focused on [...]
House Sparrows as Sentinels of Childhood Lead Exposure
Published: 2024-01-04
Subjects: Environmental Health and Protection, Environmental Monitoring, Environmental Sciences, Physical Sciences and Mathematics
Our understanding of connections between human and animal health has advanced substantially since the canary was introduced as a sentinel of toxic conditions in coal mines. Nonetheless, the development of wildlife sentinels for monitoring human exposure to toxins has been limited. Here, we capitalized on a three-decade long child blood lead monitoring program to demonstrate that the globally [...]
Quantifying clearance rates of restored shellfish reefs using modular baskets

Shellfish reefs are among the most degraded ecosystems globally, prompting substantial efforts to restore them. While biodiversity gains of restored reefs are well documented, other ecosystem services such as water filtration remain poorly quantified. We present a novel way of measuring water filtration by restored reefs using modular restoration structures called Robust Oyster Baskets (ROB 400). [...]
Patterns and drivers of population trends on individual Breeding Bird Survey routes using spatially explicit models and route-level covariates

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 [...]
