Implementing real‐time acoustic monitoring for conservation: A case study using edge computing and satellite transmission

open access: yesConservation Science and Practice, EarlyView.
We evaluated a prototype acoustic monitoring device that performs onboard species classification and transmits detection summaries via satellite, enabling near real‐time data access from remote field sites. Deployed alongside conventional autonomous recording units at eight Northern Spotted Owl territories, the system demonstrated successful ...

Utilizing traditional literature to triangulate the ecological history of a tropical savanna

open access: yesPeople and Nature
The ecological history of tropical savannas remains a subject of intense debate and of high conservation relevance. Despite emerging evidence suggesting the antiquity of tropical savannas, the misconception that all tropical savannas are products of ...

Geographical distribution of the Pinnated Bittern (Botaurus pinnatus): Update and seasonal movement pattern

open access: yesIbis, EarlyView.
The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...

Impacts of biomass burning in Southeast Asia on ozone and reactive nitrogen over the western Pacific in spring [PDF]

open access: yes, 2004
Aircraft measurements of ozone (O3) and its precursors (reactive nitrogen, CO, nonmethane hydrocarbons) were made over the western Pacific during the Transport and Chemical Evolution Over the Pacific (TRACE-P) campaign, which was conducted during ...

Time‐calibrated relationships of a rare cave catfish (Trichomycterus rubbioli): Shedding light on troglobitic lifestyle origin in the Brazilian caatinga

open access: yesJournal of Fish Biology, EarlyView.
Abstract Catfishes of the subfamily Trichomycterinae comprise the most diverse fish group with species adapted to live in Neotropical caves, but past evolutionary scenarios that have driven the origin of these troglobitic species remain unknown. We herein investigate the phylogenetic position of the cave‐restricted Trichomycterus rubbioli, endemic to ...

The influence of tropical grass species on soil nitrification and denitrification across savanna ecosystems

open access: yesGeoderma
Although limited by nutrient-poor soils primary productivity in certain humid savannas can be as high as in tropical forests. This high productivity can be partly attributed to the ability of certain perennial grasses (Poaceae) to inhibit nitrification ...

Ecological research in the Large Scale Biosphere Atmosphere Experiment in Amazonia: A discussion of early results [PDF]

open access: yes, 2004
The Large-scale Biosphere–Atmosphere Experiment in Amazonia (LBA) is a multinational, interdisciplinary research program led by Brazil. Ecological studies in LBA focus on how tropical forest conversion, regrowth, and selective logging influence carbon ...

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

open access: yesJournal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...
