Changing patterns of colonisation and persistence during the wolf recolonisation of the human‐dominated Italian alpine region

open access: yesEcography, EarlyView.
Dynamic occupancy models are fundamental for understanding complex species recolonisation processes, as they allow the assessment of both colonisation and persistence probabilities over time. Using a dynamic occupancy model and a large‐scale multi‐year dataset on wolf presence collected in the Italian alpine region between 2014 and 2020, we analysed ...

A practical guide to species trend detection with unstructured data using local frequency scaling (Frescalo)

open access: yesEcography, EarlyView.
Accurately measuring biodiversity change remains a central challenge in ecology. Beyond the general idea of quantifying temporal species frequency changes, several sampling‐related biases in data collection remain key methodological challenges to consider. Long‐term standardized ecological data are rare, and most available datasets exhibit considerable

Geographic biases and gaps in the sampling of plant–pollinator networks

open access: yesEcography, EarlyView.
Plant–pollinator interactions are essential for maintaining biodiversity and supporting food production, yet inferences drawn from network syntheses may be shaped by where interaction data are generated and which datasets are most reused. Here, we quantify the global distribution of published plant–pollinator networks, assess how publication rates vary

Floral Maturation and Insect Visitors of Pachyptera hymenaea (Bignoniaceae)

open access: yesBiotropica, 1977
Flowers of the woody vine Pachyptera hymenaea change from dark lavender to light lavender or white in three days while retained on plants. By the time flowers are three days old, they do not contain pollen or nectar, but may attract pollinators to the plants. Thrips and weevils preyed upon reproductive parts of P. hymenaea.

Defining the pollinator garden: is conceptual flexibility a feature or a bug?

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Ecologists often aim to reduce conceptual ambiguity by attempting to create rigid shared lexicons. These efforts imply that ambiguity is undesirable. In some contexts, however, conceptual flexibility comes with under‐discussed benefits. Here, we use the lens of pollinator gardening to explore how conceptual flexibility is built into participatory ...

Floral Visitors and Florivory in Tacinga inamoena (Cactaceae) in the Ex Situ Collection of the Rio de Janeiro Botanical Garden

open access: yesJournal of Zoological and Botanical Gardens
Tacinga inamoena (K. Schum.) N.P. Taylor & Stuppy (Cactaceae, Opuntioideae) is a native Brazilian species found in the Caatinga phytogeographic domain. Although its flowers are adapted for bird pollination (ornithophily), few birds visit these plants in ...

Potential pollinators and robbers: a study of the floral visitors of Heliconia angusta (Heliconiaceae) and their behaviour

open access: yesJournal of Pollination Ecology, 2011
Floral syndromes are traditionally thought to be associated with particular pollinator groups. Ornithophilous flowers tend to have traits that facilitate bird pollination such as having long, narrow, tubular corollas, often vivid coloration and diluted ...

Exposure of Healthy Individuals to Pleasant Odours During Sleep: Effects on Odour Identification and Sleep Quality

open access: yesFlavour and Fragrance Journal, EarlyView.
Sleeping with pleasant odours was associated with improved cued odour identification, particularly in the sandalwood group. Subjective night‐time awakenings showed a descriptive decrease. EEG data did not reveal robust changes in sleep architecture, though exploratory analyses suggested potential benefits for individuals with poorer baseline sleep ...

Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

open access: yesFlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

The influence of El Niño and edge effects on the reproductive phenology and floral visitors of Eschweilera tetrapetala Mori (Lecythidaceae), an endemic species of the Atlantic Forest of northeastern Brazil

open access: yesActa Botânica Brasílica, 2017
We compared the reproductive phenology and floral visitors of Eschweilera tetrapetala growing along the edge and in the interior of a submontane forest in the Chapada Diamantina mountains, Bahia State, Brazil.
