On the Benthic Invertebrate Megafauna at the Mid-Atlantic Ridge, in the Vicinity of the Charlie-Gibbs Fracture Zone

, 2012
Little is known about the fauna that inhabits non-chemosynthetic environments associated with mid-ocean ridges. This thesis investigates a ridge and fracture zone system to assess its influence as a barrier to faunal dispersal, and as a unique bathyal ...

Megagrazer loss drives complex landscape-scale biophysical cascades

Environmental Research Letters
Wild animals can modulate ecosystem-climate feedbacks, e.g. through impacts on vegetation and associated carbon dynamics. However, vegetation cover and composition also affect land surface albedo, which is an important component of the global energy ...

Exploring legal‐ and health‐risk messaging to reduce demand for elephant skin

Conservation Biology, EarlyView.
Abstract Asian elephants (Elephas maximus) are poached for an illegal trade in their skins, which are used in traditional medicine in Africa and Asia. We explored whether messages about the legal and health risks of using elephant skin for medicinal purposes (stomach illness) could reduce such consumption.

Limited elephant impacts on baobabs despite increasing elephant densities in a newly established protected area

Conservation Science and Practice, EarlyView.
Researchers combined aerial and ground surveys to map baobab distribution and assess elephant herbivory impacts on baobabs across Karingani Game Reserve, Mozambique. Researchers found that aerial surveys were an effective tool for mapping baobabs and that baobabs were more likely to occur closer to permanent water, at lower elevations, and in areas ...

Megafauna pleistocênica do Brasil: revisão sobre os indícios de interação hominíneos-megafauna [PDF]

, 2022
South America has suffered the greatest proportional loss of species diversity of Pleistocene megafauna, more than any other continent. Estimates indicate that about 80% of the genus of animals weighing more than 44 kg have been lost.

Understanding multiple pathways of the impacts of socio‐economic shocks on large carnivores

People and Nature
Large carnivores are ecologically, economically and socially important, but they are also among the most threatened species worldwide. These species face numerous threats, most importantly habitat transformation, prey depletion and hunting.

Protecting temperate old‐growth forests as biotic microrefugia amid climate change

Conservation Science and Practice, EarlyView.
Old‐growth forests are essential biotic microrefugia, providing high carbon storage, biodiversity, and stable microclimates that protect understorey species from climatic extremes. Their resilience to drought and disturbance makes them more effective than younger forests, yet habitat loss, fragmentation, and climate change increasingly threaten these ...

Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

Fisheries Management and Ecology, EarlyView.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.

DNA extracted from boiled archival fish bones yields high‐quality whole‐genome sequencing data

Journal of Fish Biology, EarlyView.
Abstract Archival samples provide a unique source of organismal DNA, offering the potential to extend the temporal scale of genetic studies by decades to centuries. Fish hard structures, such as otoliths and scales, serve as records for fish collected during fisheries monitoring across a large spatiotemporal scale.

Ecological controls on density, diversity and community structure of Polar Megabenthos

, 2005
Polar deep water environments are poorly studied. This thesis investigates fundamental questions as to the nature of controlling factors on megabenthic communities as well as the diversity, densities and distributions of organisms present.The deep (1000 ...
