McMurdo Dry Valley lake edge ‘moats’: the ecological intersection between terrestrial and aquatic polar desert habitats

Antarctic Science
AbstractAquatic ecosystems - lakes, ponds and streams - are hotspots of biodiversity in the cold and arid environment of Continental Antarctica. Environmental change is expected to increasingly alter Antarctic aquatic ecosystems and modify the physical characteristics and interactions within the habitats that they support.

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Soil networks become more connected and take up more carbon as nature restoration progresses

Nature Communications, 2017
Effects of habitat restoration on belowground organisms and ecosystem processes are poorly understood. Morriën and colleagues show that changes in the composition and network interactions of soil biota lead to improved carbon uptake efficiency when ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

Biological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Microcosms as an implement for assessing ecological processes in aquatic and terrestrial environments. Review

Environment Protection Engineering
Currently, microcosms are used for research and assessment of environmental impacts on the environmental components. Microcosms are useful instruments in ecological studies, toxicology, and ecotoxicology. Microcosms allow the experimental study of ecosystems in a controlled medium. This review article is focused on the experiences of the use of aquatic

Fear of grazing rivals the toxin‐inducing effects of nutrients in two marine harmful algae – a meta‐analysis

Biological Reviews, EarlyView.
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...

The relationship between the feather tuft of the uropygial gland and terrestrial/aquatic birds [PDF]

, 2013
The bird´s uropygial gland has a papilla in its caudal end and it can also show a feather tuft. These feathers may have a raquis or not. The purpose of our study was to compare the number, dimensions and types of the tuft´s feathers in aquatic and ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...
