Most evaluations of the effects of human activities on wild animals have focused on estimating changes in abundance and distribution of threatened species; however, ecosystem disturbances also affect aspects of animal behavior such as short-term movement, activity budgets, and reproduction. [...] Key Method We used continuous acoustic and seismic monitoring to evaluate the short-term effects of seismic prospecting for oil on forest elephants (Loxodonta cyclotis) in Gabon, Central Africa.Expand
Soundscape analysis and acoustic monitoring document impacts of natural gas exploration on biodiversity in a tropical forest
Abstract Natural resource extraction is increasing rapidly in tropical forests, but we lag behind in understanding the impacts of these disturbances on biodiversity. In high diversity tropical
Automated detection of low-frequency rumbles of forest elephants: A critical tool for their conservation.
TLDR
An automated elephant call detection algorithm that was tested on nearly 4000 h of field recordings collected from five forest clearings in Central Africa, including sites both inside protected areas and in logging concessions suggest that this algorithm can enable analysis of long-term recording datasets or facilitate near-real-time monitoring of elephants in a wide range of settings and conditions.
Acoustic monitoring for conservation in tropical forests: examples from forest elephants
Summary The accelerating loss of biodiversity worldwide demands effective tools for monitoring animal populations and informing conservation action. In habitats where direct observation is difficult
Bioacoustic monitoring of animal vocal behavior for conservation
The popularity of bioacoustics for threatened species monitoring has surged. Large volumes of acoustic data can be collected autonomously and remotely with minimal human effort. The approach is
Assessing Raspberry Shake and Boom Sensors for Recording African Elephant Acoustic Vocalizations
Acoustic sensors are increasingly being used in ecological and conservation research, but the choice of sensor can be fraught with trade-offs. In this work we assess the performance of the Raspberry
Opening a larger window onto forest elephant ecology
African forest elephants (Loxodonta cyclotis) can be observed reliably in forest clearings but are difficult to observe directly in their otherwise forested habitat. To obtain data on population
Establishing the fundamentals for an elephant early warning and monitoring system
TLDR
This work presents a method for the automated detection of elephant rumbles that is robust to the diverse noise sources present in situ and shows that tracking elephants in wildlife videos is feasible and particularly robust at near distances.
The consequences of poaching and anthropogenic change for forest elephants.
TLDR
Conservationists are encouraged to look beyond documenting forest elephant population decline and address the causes of these declines when developing conversation strategies and lessons learned from West African elephant population loss and habitat fragmentation should be used to inform strategies for land-use planning and managing human-elephant interactions.
Bioacoustic monitoring reveals shifts in breeding songbird populations and singing behaviour with selective logging in tropical forests
TLDR
It is demonstrated that bioacoustic monitoring can be used to not only estimate important population parameters of occupancy and abundance across a diverse tropical songbird community, but also enables quantification of behaviours considered relevant to individual fitness, yet unobtainable with conventional methods (e.g. point counts).
Effects of Anthropogenic Noise on Animals
The world is full of sounds of abiotic and biotic origin, and animals may use those sounds to gain information about their surrounding environment. However, it is becoming increasingly clear that the

Flying high--assessing the use of the aerosphere by bats.
TLDR
How integration of a diverse array of remote sensing tools with data on species distribution and species traits, such as mobility and edge-sensitivity, might provide novel opportunities for the development, and application of conservation-oriented monitoring systems is discussed.

TLDR
This study played back seismic replicates of elephant alarm vocalizations to herds of wild African elephants in their natural environment and observed significant behavioral changes indicating that they had detected seismic signals.

Unusually extensive networks of vocal recognition in African elephants
TLDR
Female elephants appear to have unusually extensive networks of vocal recognition, which may prove to be typical of long-lived species that have both fluid social systems and the means for long-distance vocal communication.
African Elephants Respond to Distant Playbacks of Low-Frequency Conspecific Calls
TLDR
The hypothesis that the very low-frequency calls of elephants function in communication between individuals and groups of elephants separated by distances of several kilometers is consistent with the hypothesis that these calls are audible to elephants.
