Land Degradation, Cultural Ecosystem Services, and Ecosystem Disservices in the Sumapaz Páramo, Colombia: An Integrated Socioecological Assessment

Land Degradation &Development, EarlyView.
ABSTRACT Understanding the relationships among land degradation, ecosystem functioning and human well‐being is essential for conserving tropical high‐mountain ecosystems. This study examined the relationships among land degradation, Cultural Ecosystem Services (CES), ecosystem disservices (EDS) and visitor perceptions at Laguna Colorados in the Sumapaz

A structured multidisciplinary home parenteral nutrition program in a public healthcare system: Implementation model, nursing‐led training protocol, and 11‐year safety outcomes

Nutrition in Clinical Practice, EarlyView.
Abstract Background Home parenteral nutrition (HPN) is the standard of care for adults with chronic intestinal failure (CIF), but evidence from publicly funded healthcare systems in middle‐income countries is limited. This study describes an 11‐year experience of a structured, nursing‐led HPN program within Brazil's Unified Health System (SUS ...

Proximity to wind turbines altered plant–pollinator dynamics in prairie and sagebrush ecosystems in Wyoming, USA

Nordic Journal of Botany, EarlyView.
Wind turbines influence several abiotic conditions in the environments they are sited in and may influence the behavior and movement of insect pollinators. It is unknown how operating turbines influence plant–pollinator interactions. To investigate if pollination dynamics could be affected by the presence of wind turbines, we recorded videos of ...

Synergistic effect of honeybees and wild floral visitors in promoting sweet cherry fruit set in central Chile

Biological Research
Background Recent evidence highlights the key role of wild insects as pollinators in agroecosystems, enhancing fruit set in crops such as sweet cherry (Prunus avium). In Chile, the contribution of wild insects to crop yield remains poorly understood, and

A new old species of Tetracera (Dilleniaceae) from Espinhaço Range, Brazil

Nordic Journal of Botany, EarlyView.
Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for the genus bearing a single carpel

Two new endemic species of Portulaca (Portulacaceae) from the Brazilian Pampa grasslands

Nordic Journal of Botany, EarlyView.
Portulaca L. is a monophyletic, cosmopolitan genus of succulent plants comprising ca 153 species, with particularly high diversity in xerophytic ecosystems in tropical and subtropical regions. Based on morphological evidence, we describe and illustrate two new species from the Brazilian Pampa, Portulaca guaritensis and Portulaca guenoa.

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

Review on Floral Biology and Insect Floral Visitors of Bottle Gourd [Lagenaria siceraria (Molina) Standley]

Journal of Scientific Research and Reports
Pollination is vital for the survival of cross-pollinated plants, achieved through wind, water, and animal vectors. In animals, insects are the major vectors of pollination, including cucurbitaceous crops, where the bottle gourd is monoecious with the diurnal, crepuscular, and nocturnal habit of anthesis.
