Phenology Across Scales: An Intercontinental Analysis of Leaf‐Out Dates in Temperate Deciduous Tree Communities

open access: yesGlobal Ecology and Biogeography, Volume 33, Issue 12, December 2024.
ABSTRACT Aim To quantify the intra‐community variability of leaf‐out (ICVLo) among dominant trees in temperate deciduous forests, assess its links with specific and phylogenetic diversity, identify its environmental drivers and deduce its ecological consequences with regard to radiation received and exposure to late frost.

The Sociality of Form: Camillo Sitte's Urban Morphologies

open access: yesThe German Quarterly, Volume 97, Issue 4, Page 490-505, Fall 2024.
Abstract This article examines a text by a lesser‐known figure of fin‐de‐siècle Vienna, Camillo Sitte's Der Städtebau nach seinen künstlerischen Grundsätzen (1889), tracing the relationship between urban form and social structure in Sitte's treatise. It identifies the key points of this relationship in terms of causality: the form of public spaces can ...

EXAMINATION OF THE SIMULATED THERMAL CONDITIONS IN A POPULAR PLAYGROUND RELATED TO THE HUMAN REACTIONS AND THE JUDGMENT OF THE AREA DESIGN [PDF]

open access: yes, 2013
In the field of urban bioclimatology an important and timely research direction today is to examine the thermal conditions of public places. In our study, human thermal comfort analysis was performed in a modern and well-attended children playground ...

A niche‐based theory of island biogeography

open access: yesEcology and Evolution, Volume 14, Issue 6, June 2024.
The equilibrium theory of island biogeography is a widely applied dynamic theory proposed in the 1960s to explain why islands have coherent differences in species richness. Here, we show that the number of climatic niches on islands is also an important predictor of the species richness of plants, herpetofauna and land birds, and we therefore propose a

Contribution to the bioclimatology of Portugal. [PDF]

open access: yes, 1991
47 meteorological stations from Portugal have been analyzed using temperature and rain data for the period 1931-1960. The most usual bioclimate Índices in phytosociology and the Montero de Burgos & González Rebollar's bioclimatic intensities have been ...

Biological Control of the Chagas Disease Vector Triatoma infestans with the Entomopathogenic Fungus Beauveria bassiana Combined with an Aggregation Cue: Field, Laboratory and Mathematical Modeling Assessment [PDF]

open access: yes, 2015
Background: Current Chagas disease vector control strategies, based on chemical insecticide spraying, are growingly threatened by the emergence of pyrethroid-resistant Triatoma infestans populations in the Gran Chaco region of South America. Methodology

Decoding autumn phenology: Unraveling the link between observation methods and detected environmental cues

open access: yesGlobal Change Biology, Volume 30, Issue 3, March 2024.
Understanding autumn phenology is challenging due to the multitude of likely environmental cues and substantial variations in timing caused by different derivation methods. This study in a German beech forest investigated start and end (EOS) of the growing season from 2000 to 2020 using four derivation methods and determined their influence on a ...

Bayesian hierarchical models for analysing the spatial distribution of bioclimatic indices [PDF]

open access: yes, 2017
A methodological approach for modelling the spatial distribution of bioclimatic indices is proposed in this paper. The value of the bioclimatic index is modelled with a hierarchical Bayesian model that incorporates both structured and unstructured random

Impacts of climate change on tourism in the Mediterranean: Adaptive responses

open access: yes, 2000
Key sensitivities to Mediterranean tourism include drought and heatwaves, both of which are likely to increase with projected greenhouse warming. Adaptive responses must include lengthening of the present season and particularly taking care to cater for ...
