Multi-dimensional niche segregation of sympatric breeding seabirds in the Xisha Archipelago

open access: yesAvian Research
Studying coexistence mechanisms is practically important for understanding and conserving marine biodiversity and community structure. Tropical marine ecosystems may exhibit higher competition between top predators due to generally low primary ...

Foraging Behaviours of Breeding Arctic Terns Sterna paradisaea and the Impact of Local Weather and Fisheries

open access: yesFrontiers in Marine Science, 2022
During the breeding season, seabirds are central place foragers and in order to successfully rear chicks they must adjust their foraging behaviours to compensate for extrinsic factors.

Analyzing User Behavior Patterns in Adaptive Exploratory Search Systems with LifeFlow [PDF]

open access: yes, 2011
Adaptive exploratory search is a method that can provide user-centered personalized search results by incorporating interactive user interfaces. Analyzing the user behavior pat- terns of these systems can be complicated when they sup- port transparent ...

Geolocator study reveals east African migration route of Central European Common Terns

open access: yesAvian Research, 2020
Background The majority of European Common Terns (Sterna hirundo) migrate south along the western coast of Europe and Africa, while birds from eastern regions are known to cross the Mediterranean Sea from east to west or migrate along the eastern African

Foraging plasticity in seabirds: A non-invasive study of the diet of greater crested terns breeding in the Benguela region. [PDF]

open access: yesPLoS ONE, 2018
Marine predators, such as seabirds, are useful indicators of marine ecosystem functioning. In particular, seabird diet may reflect variability in food-web composition due to natural or human-induced environmental change. Diet monitoring programmes, which

Modelling forest dynamics using integral projection models and repeat lidar

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Forests are facing increasing pressure from climate change and disturbance, yet linking individual tree trajectories to whole‐forest outcomes remains a major challenge. Our study integrates repeat airborne lidar with an Integral Projection Model to analyse demographic processes at the landscape scale.

Nest-site selection by roseate terns breeding on aride island, Seychelles [PDF]

open access: yes, 1998
Nest-site selection by tropical Roseate Terns (Sterna dougallii) was examined on Aride Island, Seychelles. Continuous variables reflecting concealment of the nest site, shelter, vegetation cover and intraspecific nest density were measured for nest-sites

Programmable type III-A CRISPR-Cas DNA targeting modules. [PDF]

open access: yesPLoS ONE, 2017
The CRISPR-Cas systems provide invader defense in a wide variety of prokaryotes, as well as technologies for many powerful applications. The Type III-A or Csm CRISPR-Cas system is one of the most widely distributed across prokaryotic phyla, and cleaves ...
