Remote sensing of chlorophyll concentration: State-of-the-art, 1975 [PDF]

open access: yes
Remote measurement of chlorophyll concentration of the world's oceans from satellite observations could potentially be extremely useful for assessments of productivity in large areas for which measurements by other means would be impractical.

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

A Novel Multidisciplinary Approach for Reptile Movement and Behavior Analysis

open access: yesIntegrative Zoology, EarlyView.
We present a novel multidisciplinary approach capable of advancing research on reptiles’ behavior. Our approach uses integrated tools and methods for the digitization, reconstruction, and visualization of reptiles and their behavior. We (i) record movement through tri‐axial accelerometers, video cameras, and motion capture systems; (ii) ground‐truth ...

A nature‐positive world is more than the sum of its parts

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Adoption of the Kunming–Montreal Global Biodiversity Framework (KM‐GBF) has led to further growth in attention being directed to the challenge of bending the curve of biodiversity loss to achieve a nature‐positive world. However, concerns have been raised that, unless progress towards achieving net gain in biodiversity can be measured ...

CheckEM: An open‐source toolkit for standardising, cleaning and visualising stereo‐video fish survey data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Effective research and monitoring requires accurate, interoperable and representative data. Stereo‐video based methods are commonly used to survey fish and are rapidly expanding globally due to their cost‐effectiveness, ability to provide accurate body size measurements, non‐destructive approach and capacity to create permanent data records ...
