A Comparison of Mobile Laser Scanning Data Acquisition Methods in Closed Forest, Open Woodland and Sub‐Alpine Woodland Ecosystems

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that the mobile laser scanning (MLS) sampling density required to reliably characterise vegetation structure increases with a site's structural complexity. Applying a five‐level acquisition framework across open woodland, closed forest and sub‐alpine woodland ecosystems, we found that longer scanning paths increased the ...

Modern pollen rain of an upland area: implications of pollen dispersal for interpreting palaeoenvironmental records

open access: yesBoreas, EarlyView.
A long‐term perspective on landscape evolution is critical for understanding past land‐use activity, land cover–climate feedbacks and, notably, for establishing a factual basis for conservation. Fossil pollen analysis provides a means to achieve this. Biases pertaining to pollen productivity, pollination processes and basin size, however, mean there is

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

open access: yesIbis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

Cultural and ecological baselines inform an eco‐cultural vision for Weka (Gallirallus australis) restoration in southern New Zealand

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Eco‐cultural restoration requires targets that reflect cultural values and ecological conditions. We present an integrative approach combining cultural and ecological baselines to inform future eco‐cultural restoration of Buff weka (Gallirallus australis hectori), a flightless bird of deep cultural significance to the Ōtākou Māori
