Songs in passerine birds are important for territory defense and mating. Speciation rates in oscine passerines are so high, due to cultural evolution, that this bird lineage makes up half of the extant bird species. Leaf warblers are a speciose Old-World passerine family of limited morphological differentiation, so that songs are even more important for species delimitation. We took 16 sonographic traits from song recordings of 80 leaf warbler taxa and correlated them with 15 potentially explanatory variables, pairwise, and in linear models. Based on a well-resolved molecular phylogeny of the same taxa, all pairwise correlations were corrected for relatedness with phylogenetically independe…

Stopover strategies in birds: a review of methods for estimating stopover length

1999

This study categorizes and reviews methods used to estimate stopover length in migratory birds. Stopover length is an important variable in analysing migration strategies. The analysis of the stopover pattern of migratory birds typically attempts to investigate variability in the number of stopovers and in the length of time spent at stopover sites in relation to species, age, sex and body condition. Although the number of capture-recapture studies analysing stopover length has increased substantially, most are analysed using the simple last-first capture method which gives biased estimates. The use of mathematical models to calculate stopover length is uncommon. Most researchers assume hom…

Landscape Dynamics and Cultural Contacts in the Territory of Himera in the Archaic Period

2022

In central-northern Sicily, the watershed area between the northern and southern Imera and Platani rivers has already been recognized for years as a pivotal area in relations between the different areas of the island, both in reference to the political and economic projections of the colonial poleis , especially between Himera, Akragas, both in reference to economic relations and cultural contacts with indigenous communities. This area is very crucial context of encounter and confrontation between communities, in which complex systems of territorial articulation can be grasped. The position of the settlements along the basins of the two Himera highlights a close connection in terms of inter…

Regulating Internet Trade in CITES Species

2013

International trade in species that are or may be endangered by collection from the wild is regulated under the Convention on International Trade in Endangered Species of wild fauna and flora (CITES) for 176 member States (Parties). Internet commerce is a relatively new route for such trade. In 2007, the CITES Secretariat asked Parties to collect information on internet wildlife trade and report problems and implemented regulations. The reports indicated it was difficult to even approximate the influence of e-commerce on CITES-listed species (CITES Secretariat 2009). We report a case study in which we quantified international transactions over an internet auction site of CITES-listed cacti …

Crónica de una pandemia: confinamiento en Castelló de la Plana, España

2021

Este artículo presenta los resultados de una investigación comenzada a raíz de la declaración del estado de alarma en España (Real Decreto [RD] No. 463/2020, de 14 de marzo) después que la Organización Mundial de la Salud (OMS) declarase la enfermedad por coronavirus 2019 (COVID-19) como pandemia el día 11 de marzo de 2020. Este decreto limitaba la libre circulación de las personas, así como el derecho de reunión, tanto en lugares públicos como privados, además de imponer la obligatoriedad de mantener una distancia de seguridad entre los individuos y la limitación del aforo en aquellos establecimientos que permanecían abiertos, entre otras medidas. Todo ello supuso un cambioen las rutinas d…

Social impacts of biodiversity offsetting: A review

2022

Biodiversity offsetting is the widely studied last step of the mitigation hierarchy. Despite numerous studies and the methodological development completed for biodiversity calculations, the human aspect remains unsolved. Biodiversity conservation is typically governed at national or state levels, but the harm caused to biodiversity as well as people occurs locally. In biodiversity offsetting, biodiversity values can be relocated far from the original area, but relocating the values people hold regarding their nearby nature may not be possible. Acknowledging the local people's hopes and values may further complicate biodiversity offsetting, therefore it emphasises even more the need to avoid…

For the use of sound. Film sound analysis for audio-description: some key issues

2012

This article aims to outline the issues involved in the production and reception of film sound with a view to identifying its challenges for audio-description (AD). It thereby hopes to provide insights into the way in which a careful analysis and integration of film sound and sound effects are required for the production of coherence in AD, if it is to function as part of a new filmic text. However, the article also points to the limits of analysis and interpretation, and to the need for reception research as well as collaboration with visually impaired users. A detailed analysis of a scene from Saving Private Ryan (Spielberg 1998), a film that won an Oscar for best sound effect editing, de…

Quantifying the Indicator Power of an Indicator Species

2009

Biodiversity indicator species are needed for classifying biotopes and sites for conservation, and a number of methods have been developed for determining indicator species for this purpose. Nevertheless, in addition to site classification, there is sometimes a need to define an indicator species that indicates the occurrence of another species. For example, when a species of interest (target species) is difficult to detect or identify, a reliable indicator species can function as a tool that saves time and money. We derived a method that provides a quantitative measure of the indicator power (IP) of an indicator species for the target species or any species assemblage. We calculated the me…

Macrobotanical evidence (wood charcoal and seeds) from the Middle Palaeolithic site of El Salt, Eastern Iberia: Palaeoenvironmental data and plant re…

2018

Despite the current growing number of studies that focus on macrobotanical remains from Middle Palaeolithiccontexts, plant use among hunter-gatherer societies remains unknown in many regions of Europe. Large-scaleflotation of archaeological sediments has made it possible to recover a large amount of plant remains (fruits,seeds and wood) from units VIII, IX, Xa and Xb at El Salt, Eastern Iberia (49.2–52.3 ka BP). The combination ofanthracological and carpological analyses has provided a more accurate picture of the Middle Palaeolithiclandscape in the Serpis valley, as well as significant information about other possible uses of plants, not only asfuel, but for woodworking or food, for instan…

*-Graded Capelli polynomials and their asymptotics

2022

Let [Formula: see text] be the free *-superalgebra over a field [Formula: see text] of characteristic zero and let [Formula: see text] be the [Formula: see text]-ideal generated by the set of the *-graded Capelli polynomials [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] alternating on [Formula: see text] symmetric variables of homogeneous degree zero, on [Formula: see text] skew variables of homogeneous degree zero, on [Formula: see text] symmetric variables of homogeneous degree one and on [Formula: see text] skew variables of homogeneous degree one, respectively. We study the asymptotic behavior of the sequence of *-graded codimensions of [Formula: se…
