Viability analysis and the importance of fine‐scale variables influencing roadkills of a toad population

The Journal of Wildlife Management, EarlyView.
Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...

Aiouea riedeliana comb. nov. (Lauraceae) from Brazil, with an amended description and provisional extinction threat assessment

Nordic Journal of Botany, EarlyView.
Aiouea riedeliana (Kosterm.) P.L.R.Moraes and Brotto is the new combination for Cinnamomum riedelianum Kosterm., whose type‐bringing synonym is Persea riedelii Meisn. The placement of this taxon in Aiouea is presented, justified, and illustrated here, disagreeing with its previous classification in Ocotea, as Ocotea riedeliana (Kosterm.) Kottaim., then

Water Losses and Environmental Efficiency in Urban Water Supply Systems: A Comparative Assessment for Spain and Portugal

Sustainable Development, EarlyView.
ABSTRACT Water losses are a critical environmental and operational challenge, especially in regions exposed to increasing water stress. This study assesses the environmental productivity of municipal water supply services in Spain and Portugal during the period 2014–2022, explicitly treating losses as an undesirable output.

Gross Agricultural Emissions and Unequal Mitigation Pathways in the Brazilian Legal Amazon: Implications for Climate Justice and the Sustainable Development Goals

Sustainable Development, EarlyView.
ABSTRACT Climate mitigation policies in the Brazilian Legal Amazon have largely focused on aggregate or net emissions, providing limited evidence on how gross agricultural emissions reveal the intensity of productive emission sources independently of carbon removals.

Good days, bad days: Weather patterns driving bryophyte carbon‐exchange dynamics in tropical rainforest canopies

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The physiology of tropical mosses, liverworts and lichens may be challenged by the daily weather patterns in lowland rainforests. Since these poikilohydric organisms can only photosynthesize and respire when hydrated, unfavourable timing of light and water availability (
