Conventional to Deep Learning Methods for Hyperspectral Unmixing: A Review

Remote Sensing
Hyperspectral images often contain many mixed pixels, primarily resulting from their inherent complexity and low spatial resolution. To enhance surface classification and improve sub-pixel target detection accuracy, hyperspectral unmixing technology has ...

Assessing the suitability of a one‐time sampling event for close‐kin mark‐recapture: A caribou case study

Ecology and Evolution
Abundance estimation is frequently an objective of conservation and monitoring initiatives for threatened and other managed populations. While abundance estimation via capture–mark–recapture or spatially explicit capture–recapture is now common, such ...

Estimating Demographic Parameters for Bearded Seals, Erignathus barbatus, in Alaska Using Close‐Kin Mark‐Recapture Methods

Evolutionary Applications
Reliable estimates of population abundance and demographics are essential for managing harvested species. Ice‐associated phocids, “ice seals,” are a vital resource for subsistence‐dependent coastal Native communities in western and northern Alaska, USA ...

Bellwethers of change: population modelling of North Pacific humpback whales from 2002 through 2021 reveals shift from recovery to climate response

Royal Society Open Science
For the 40 years after the end of commercial whaling in 1976, humpback whale populations in the North Pacific Ocean exhibited a prolonged period of recovery.

Harvest restrictions fail to influence population abundance

Ecosphere
Evaluating changes in population abundance is essential to assess the efficacy of conservation actions. Antler point restrictions are a high‐profile regulatory action aimed to advance male age structure in cervid populations, but there is a limited ...

A new double observer‐based census framework to improve abundance estimations in mountain ungulates and other gregarious species with a reduced effort

Ecological Solutions and Evidence
Estimating animal abundance has a key role to play in ecology and conservation, but survey methods are always challenged by imperfect detection. Among the techniques applied to deal with this issue, Double Observer (DO) is increasing in popularity due to
