Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

A study of the South Atlantic Ocean: Circulation and Carbon Variability

, 2013
This analysis indicates that the Southern Ocean provides a trong sink, yet low storage, for atmospheric CO2. The South Atlantic Ocean, in particular, facilitates major interbasin exchange through the interaction of the Antarctic Circumpolar Current (ACC),

RETRACTED: Polymer-Coated Nickel Nanoparticles for CO₂ Capture in Seawater

Separations
Carbon capture and storage (CCS) technologies are employed to mitigate global warming by removing carbon from the atmosphere. To enhance carbon capture efficiency, nanoparticles have gained considerable attention as catalysts due to their large surface ...

Atlantic Ocean science diplomacy in action: the pole-to-pole All Atlantic Ocean Research Alliance

Humanities & Social Sciences Communications, 2021
The ocean provides important ecosystem services to society, but its health is in crisis due to the impacts of human activities. Ocean sustainability requires ambitious levels of scientific evidence to support governance and management of human activities

Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Retroflections in the tropical Atlantic Ocean

, 2023
The upper ocean circulation is the area of confluence of two major vertical cells: the large-scale overturning Atlantic Meridional Overturning Circulation (AMOC) and the regional relatively shallow Subtropical Cells (STCs). Both meridional cells interact in a complex system of zonal currents driven by fluctuations of the trade winds.

Knowledge gaps and research directions in migration ecology for advancing the conservation of migratory songbirds

Biological Reviews, EarlyView.
ABSTRACT Understanding migration ecology is essential for effective conservation of migratory species. To achieve a comprehensive understanding of the ecology of migrating species, it is necessary to study how species react to the complex interplay of intrinsic and extrinsic conditions when optimizing their migratory journey in terms of survival ...
