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

PLoS 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 ...

Critical Success Factors and Stakeholder Influence for Environmental, Social and Governance Assessment and Reporting

Business Strategy and the Environment, EarlyView.
ABSTRACT Environmental, Social and Governance (ESG) assessment criteria have drawn substantial attention by investors in recent years. ESG factors have been considered by investors to create greater wealth and better investment decisions and opportunities. However, there are ambiguities about ESG assessment and reporting with issues of transparency and

Seasonal drivers of plant–soil–microbial community structure and functions in Western Himalayan grasslands, Pakistan

Grassland Research, EarlyView.
Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.

Nest-site habitat partitioning by Arctic, Common, and Roseate terns

Avian Conservation and Ecology
When closely related species that share aspects of their habitat niches nest in sympatry, selection is expected to favor species-specific differences in nest-site selection that allow birds to partition habitat. We tested habitat-partitioning theory in a

Social attraction used to establish Caspian tern nesting colonies in San Francisco Bay

Global Ecology and Conservation, 2019
Conservation of colonial waterbird breeding populations often includes restoring historic nesting habitat or establishing new nesting habitat in protected areas.

Experimental infection of Common Terns with Tern virus: Influenza Virus A/Tern/South Africa/1961 [PDF]

Journal of Hygiene, 1967
Experimental infection of captive Common Terns with Influenza virus A/Tern/South Africa/1961 reproduced the disease seen in the 1961 epizootic during which Tern virus was originally isolated. Infected terns excreted virus in their droppings. At death a viraemia was present but immunofluorescent studies determined the sites at which virus reproduction ...

Little penguins select more isolated nest boxes for breeding, but lay date influences breeding success

The Journal of Wildlife Management, EarlyView.
We determined that more isolated and possibly older nest boxes were selected by little penguins for breeding at Pōhatu/Flea Bay, New Zealand. However, breeding success was influenced by lay date in comparison to nest box characteristics. These findings inform immediate conservation recommendations regarding nest box design and placement.

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

Avian 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 ...

The effect of localized disturbance on the acoustic behavior of the common tern (Sterna hirundo) [PDF]

JASA Express Letters
In this study, passive acoustic monitoring was used to assess the impact of investigator disturbance on the acoustic behavior of a colony of common terns. A graded antipredator response in the colony was hypothesized, which would result in an increase in

Modelling forest dynamics using integral projection models and repeat lidar

Remote 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.
