Land cover mapping of large areas is challenging due to the significant volume satellite data acquire and process, as well lack spatial continuity cloud cover. Temporal aggregation—the use metrics (i.e., mean or median) derived from over a period time—is an approach that benefits recent increases in frequency free acquisition cloud-computing power. This enables efficient multi-temporal exploitation cloud-gap filling techniques for land mapping. Here, we provide first formal comparison...
Abstract The measurement of forest structure has evolved steadily due to advances in technology, methodology, and theory. Such have greatly increased our capacity describe key structural elements resulted a range approaches from traditional analog tools such as tapes highly derived computationally intensive methods advanced remote sensing (e.g., lidar, radar). This assortment results metrics unique each method, with the caveat that may be biased or constrained by approach taken. While...
This dataset consists of the vector version Land Cover Map 2015 (LCM2015) for Great Britain. The data set is core LCM from which full range other LCM2015 products derived. It provides a number attributes including land cover at target class level (given as an integer value and also text), pixels within polygon classified each type probability provided by classification algorithm (for details see Dataset Documentation). 21 classes are based on Joint Nature Conservation Committee (JNCC) Broad...
The structural heterogeneity of vegetation is a key factor for explaining animal diversity patterns at local scale. Improvements in airborne light detection and ranging (lidar) technologies have enabled researchers to study forest 3D structure with increasing accuracy. Most structure–animal work has focused on metrics derived from lidar returns canopy terrain features. Here, we built new based the Leaf Area Density (LAD) each height layer, used these how different aspects explain variation...
Monitoring the expansion of commodity crops in tropics is crucial to safeguard forests for biodiversity and ecosystem services. Oil palm (Elaeis guineensis) one such crop that a major driver deforestation Southeast Asia.

Abstract Climate adaptation strategies are being developed and implemented to protect biodiversity from the impacts of climate change. A well‐established strategy involves identification addition new areas for conservation, most countries agreed in 2010 expand global protected area (PA) network 17% by 2020 (Aichi Biodiversity Target 11). Although great efforts PA have been made, potential newly established PAs conserve under future change remains unclear at scale. Here, we conducted first...
Mapping vegetation species is critical to facilitate related quantitative assessment, and mapping invasive plants important enhance monitoring management activities. Integrating high-resolution multispectral remote-sensing (RS) images lidar (light detection ranging) point clouds can provide robust features for mapping. However, using multiple sources of RS data on a large spatial scale be both computationally sampling intensive. Here, we designed two-step classification workflow potentially...
Manakins (Pipridae) are well know for elaborate male sexual displays and ornate plumage coloration, both of which thought to have evolved as a consequence lekking breeding, the prevalent mating system in family. Less attention has been paid handful ‘drab’ manakin species, dimorphism appears be reduced or absent. Using character reconstruction, we show that these ‘exceptions rule’ represent phylogenetically independent cases losses dimorphism, such could provide focal group investigate link...
Peatlands are important reserves of terrestrial carbon and biodiversity, given that many peatlands across the UK Europe exist in a degraded state, their conservation is major area concern focus considerable research. Aerial surveys valuable tools for habitat mapping provide useful insights into condition. We investigate how SfM photogrammetry-derived topography classes may be used to construct an estimate loss from erosion features remote blanket bog habitat. An autonomous, unmanned, aerial,...
Habitat selection in avian species is a hierarchical process driven by different factors acting at multiple scales. preferences and site fidelity are two main affecting how colonial birds choose their breeding locations. Although these affect habitats, previous studies have only focused on one factor time to explain the distribution of regional Here we used 28 yr colony location data herons egrets around Ibaraki prefecture Japan order analyze relative importance habitat for selecting We...
The Banded Ground-cuckoo (Neomorphus radiolosus) is a rare, endangered, and poorly known species endemic to the Chocó Biogeographic Zone. We summarize 7 months of data from radio tracking an adult in northwestern Ecuador. Home range estimates were 42.2 ha (minimum convex polygon) 49.9 (95% kernel analysis); core area was 3.4 (50% analysis). bird favored undisturbed habitat avoided secondary forest. It primarily insectivorous rarely associated with army ants (Eciton sp.) not mammals. Breeding...
Abstract About 70% of the world's main crops depend on insect pollination. Climate change is already affecting abundance and distribution insects, which could cause geographical mismatches between their pollinators. Crops that rely primarily wild pollinators (e.g., cannot be effectively pollinated by commercial colonies honey bees) particularly in jeopardy. However, limited information plant–pollinator associations pollinator distributions complicate assessment climate impacts specific...
Abstract Birds are useful indicators of overall biodiversity, which continues to decline globally, despite targets reduce its loss. The aim this paper is understand the importance different spatial drivers for modelling bird distributions. Specifically, it assesses satellite‐derived measures habitat productivity, heterogeneity and landscape structure diversity across Great Britain. Random forest (RF) regression used assess extent a combination covariates explain woodland farmland richness....
Abstract Understanding the spatial scales at which environmental factors drive species richness patterns is a major challenge in ecology. Due to trade‐off between grain and extent, studies tend focus on single scale, effects of multiple variables operating across pattern local have rarely been investigated. Here, we related variation ground beetles, landbirds small mammals vegetation structure topography, regional climate, biome diversity glaciation history for 27 sites USA two different...

Combining remote sensing field mapping methods to study the vegetation dynamics within a coastal wetland determine habitat effects of threatened bird species (Emberiza schoeniclus witherbyi).Coastal wetlands are highly dynamic changing ecosystems because meteorology, wildlife interactions human activities. They one world's most ecosystems, threats them drive specialist unfavorable conservation status population trends. Therefore,...
Control of emerging animal diseases critically depends on their early detection. However, designing surveillance programs for exotic and is very challenging because knowledge gaps the probability incursion mechanisms spread. Using example Bluetongue Virus, which to UK, we develop a metapopulation epidemic-economic modelling framework that considers incursion, detection, spread control disease in livestock production system composed heterogeneous subpopulations. The model then embedded an...
