Climatic Specific Energy Rating Analysis of Outdoor PV Field Data

Progress in Photovoltaics: Research and Applications, EarlyView.
The study evaluates the Climatic Specific Energy Rating (CSER) of Photovoltaic device according to IEC 61853 standard series. It explores the use of long‐term PV outdoor field data in order to understand how the length and seasonality of the data acquisition period affects the reliability of the CSER parameter. It provides important insights for the PV

An Updated Simplified Energy Yield Model for Recent Photovoltaic Module Technologies

Progress in Photovoltaics: Research and Applications, EarlyView.
This study looks at the recalibration of the European Commission's PVGIS power performance model for modern crystalline silicon (cSi), cadmium telluride (CdTe) and copper indium diselenide (CIS) module technologies. The results show that the updated PVGIS model can provide a good description of the power output of the modern crystalline silicon (cSi ...

Anthromes and forest carbon responses to global change

PLANTS, PEOPLE, PLANET, EarlyView.
Forest ecosystems absorb and store about 25% of global carbon dioxide emissions annually and are increasingly shaped by human land use and management. Climate change interacts with land use and forest dynamics to influence observed carbon stocks and the strength of the land carbon sink.

Towards the sustainability of African sandalwood: Understanding the distribution and environmental requirements

PLANTS, PEOPLE, PLANET, EarlyView.
African sandalwood (Osyris lanceolata) leaves, roots, barks, fruits, and woods are used for multiple purposes throughout Asia, Africa, and Europe. The species is threatened in several eastern African countries. To improve the species' management and conservation, a habitat suitability study was undertaken in its at‐risk region in eastern Africa and ...

A Conservation Assessment and Phylogenomic Evaluation of Protection Status in the Tropical Genus Heliconia L. (Zingiberales: Heliconiaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
The primarily neotropical plant genus Heliconia has been cultivated commercially in gardens and nurseries for hundreds of years. Many of these same species are ecological keystones in their native habitats as important resources for herbivorous insects and pollinating hummingbirds, yet they face threats of habitat loss and degradation, competition with

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

Factors affecting detection and trapping efficacy of Mediterranean fruit flies

Pest Management Science, EarlyView.
Trapping efficacy for medfly and other fruit flies depends on environmental factors, with ambient conditions having the strongest effect. Cold acclimation can skew population estimates, making careful data interpretation essential for accurate population assessments and early detection of invasive pests.
