Linking species interactions with phylogenetic and functional distance in European bird assemblages at broad spatial scales

2017

Aim: Understanding the relative contribution of different species interactions in shaping community assembly has been a pivotal aim in community ecology. Biotic interactions are acknowledged to be important at local scales, although their signal is assumed to weaken over longer distances. We examine the relationship between positive, neutral and negative pairwise bird abundance distributions and the phylogenetic and functional distance between these pairs after first controlling for habitat associations. Location: France and Finland. Time period: 1984 to 2011 (Finland), 2001 to 2012 (France). Major Taxa studied: Birds. Methods: We used results from French and Finnish land bird monitoring pr…

A Territorial-driven approach to capture the transformative momentum of the Social Economy especially from the agricultural cooperatives

2021

In the last few lustrums, the literature has searched for more precise methods to assess the socio-economic importance of the Social and Solidarity Economy (SSE). On that basis, this article offers a new way of assessing the SSE impact, enhancing the understanding of the SSE potential for socio-economic transformation. An evolutionary micro–meso–macro and territorial theoretical framework is developed, utilizing, along with the assistance of a qualitative methodology, studies on the transformation promoted by the SSE on the sugar cane cluster of Veracruz (Mexico). The main results of the article are that the SSE boost beneficiaries, while the protagonists of the transformation c…

Spatially restricted expression of PlOtp, a Paracentrotus lividus Orthopedia-related homeobox gene, is correlated with oral ectodermal patterning and…

1999

ABSTRACT Several homeobox genes are expressed in the sea urchin embryo but their roles in development have yet to be elucidated. Of particular interest are homologues of homeobox genes that in mouse and Drosophila are involved in patterning the developing central nervous system (CNS). Here, we report the cloning of an orthopedia (Otp)-related gene from Paracentrotus lividus, PlOtp. Otp is a single copy zygotic gene that presents a unique and highly restricted expression pattern. Transcripts were first detected at the mid-gastrula stage in two pairs of oral ectoderm cells located in a ventrolateral position, overlying primary mesenchyme cell (PMC) clusters. Increases in both transcript abund…

Growing a Project-Based Translation Pedagogy: A Fractal Perspective

2012

Le présent article propose un cheminement fractal à travers la psychologie et la philosophie éducative, avec l’intention de faire la lumière sur une représentation arborescente de sources d’inspiration interdisciplinaires et complémentaires pour une pédagogie de la traduction par projets. Commençant par la méthode d’apprentissage socioconstructiviste proposée au tournant du millénaire, notre propos tente de brosser un vaste portrait des influences synergiques sous-jacentes à l’approche émergente « holistique-expérientielle » de la formation en traduction. Le post-modernisme, l’énaction dans les sciences cognitives, la théorie de la complexité, la théorie éducative transformationnelle et l’é…

X-Ray structure, Hirshfeld analysis and DFT studies of two new hits of triazolyl-indole bearing alkylsulfanyl moieties

2021

Two new hits of triazolyl-indole containing two different alkylsulfanyl analogues named tert-butyl 2-((4-amino-5-(1H-indol-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetate 2, and ethyl 2-((4-amino-5-(1H-indol-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetate 3 were synthesized via reaction of 4-amino-5-(1H-indol-2-yl)-1,2,4-triazol-3(2H)-thione 1 with tert-butyl bromoacetate and ethyl chloroacetate in the presence of base (Et3N). The molecular structure of 2, and 3 was confirmed by single-crystal X-ray diffraction and 1H/13C- NMR spectroscopic techniques. In compound 2, the molecular packing depends on significant O...H (9.3%), N...H (12.4%) and S...H (3.1%) as well as relatively weak C...H (14.1%), S...C (…

Parabolic equations with nonlinear singularities

2011

Abstract We show the existence of positive solutions u ∈ L 2 ( 0 , T ; H 0 1 ( Ω ) ) for nonlinear parabolic problems with singular lower order terms of the asymptote-type. More precisely, we shall consider both semilinear problems whose model is { u t − Δ u + u 1 − u = f ( x , t ) in Ω × ( 0 , T ) , u ( x , 0 ) = u 0 ( x ) in Ω , u ( x , t ) = 0 on ∂ Ω × ( 0 , T ) , and quasilinear problems having natural growth with respect to the gradient, whose model is { u t − Δ u + ∣ ∇ u ∣ 2 u γ = f ( x , t ) in Ω × ( 0 , T ) , u ( x , 0 ) = u 0 ( x ) in Ω , u ( x , t ) = 0 on ∂ Ω × ( 0 , T ) , with γ > 0 . Moreover, we prove a comparison principle and, as an application, we study the asymptotic behav…

Edaphyc characteristics and floristic composition of the seasonally dry forest la menta and timbes, Piura Region, Peru

2011

Con el objetivo de contribuir al conocimiento de los ecosistemas naturales del país, se determinó las características edáficas y la composición florística del bosque estacionalmente seco (La Menta, 04º 43' 55" LS y 80º 04' 55" LO, provincia de Piura y Timbes, 04º 44' 58" LS y 80º 03' 33" LO, provincia de Ayabaca), ambos en la región Piura, Perú. El área de estudio abarcó una extensión aproximada de 6 000 hectáreas en un rango altitudinal entre 350 m a 1 350 m. En cada bosque se muestrearon 5 transectos de 10 x 50 m a intervalos de 20 m, sumando un total de 2 500 m². El análisis de suelo reveló niveles bajos de materia orgánica, nitrógeno y potasio y medios de fósforo asimilable. Estos suelo…
