Tiny Bird, Huge Mystery-The Possibly Extinct Hooded Seedeater (Sporophila melanops) Is a Capuchino with a Melanistic Cap. [PDF]

PLoS One, 2016
المعروف على وجه اليقين فقط من عينة ذكور فريدة تم جمعها في وسط البرازيل في الربع الأول من القرن التاسع عشر، كان Sporophila melanops المهددة بالانقراض (ربما منقرضة) واحدة من الألغاز العظيمة لعلم الطيور الاستوائي الحديث، ويمكن القول إنها الوحيدة من مجموعة من الأنواع المفقودة منذ فترة طويلة من البرازيل التي لا تزال غير مكتشفة بعناد.

Arboreal monkeys facilitate foraging of terrestrial frugivores

Biotropica, Volume 53, Issue 6, Page 1685-1697, November 2021., 2021
We investigated eavesdropping and interspecific interactions in Neotropical mammals in a feeding context using playback experiments, monitoring of fruiting trees with camera traps combined with GPS data and randomised movement tracks. We found that interspecific attractions at food resources were not random and that some species were more likely to ...

Transgressive phenotypes and evidence of weak postzygotic isolation in F1 hybrids between closely related capuchino seedeaters. [PDF]

PLoS One, 2018
Postzygotic reproductive isolation may become strong only once the process of speciation is in its advanced stages. For taxa in the early stages of speciation, prezygotic reproductive isolation barriers may play a predominant role in maintaining species boundaries.

Elaboración de capuchino con prensa francesa y prensa italiana

Boletín Científico de las Ciencias Económico Administrativas del ICEA, 2022
Anteriormente se dudaba si el café era algo “bueno” para la salud, hoy día se sabe que está famosa bebida compuesta de elementos como polifenoles, diterpenos o ácidos clorogénicos, así como cafeína tiene efectos antioxidantes y antiinflamatorios, de igual forma hoy día se sabe que la cantidad de cafeína que se puede encontrar en la bebida va a depender

Ecological and morphological determinants of evolutionary diversification in Darwin's finches and their relatives

Ecology and Evolution, Volume 10, Issue 24, Page 14020-14032, December 2020., 2020
The ecological diversification of Darwin's finches is unmatched on the same archipelago by any other clade of colonising land birds. For all morphological traits, we observe an early pulse of diversification followed by prolonged periods of slower steady‐state rates of change for the tanager family a substantial increase in speciation rate in Darwin's ...

On the relative importance of ecology and geographic isolation as drivers for differentiation of call types of red crossbill Loxia curvirostra in the Palearctic

Journal of Avian Biology, Volume 51, Issue 10, October 2020., 2020
Efforts to understand the process of speciation have been central to the research of biologists since the origin of evolutionary biology as a discipline. While it is well established that geographic isolation has played a key role in many speciation events, particularly in birds, there is ongoing debate about how frequent speciation is in the partial ...

Encrucijadas religiosas y diplomacia en el Atlántico. El reino del Congo frente a la preeminencia ibérica (siglos XVI-XVII)

Estudis, 2023
La conexión que se crea entre África, Europa y América a través del tráfico de esclavos en el espacio atlántico, conforma un eje que vertebra las amplias relaciones e intereses que se establecen a partir de la cristianización del Reino del Congo.

Identifying the sister species to the rapid capuchino seedeater radiation (Passeriformes:Sporophila)

The Auk, 2013
ABSTRACT. Within the Neotropical genus Sporophila, a group of eight species known colloquially as “southern capuchinos” shows remarkable phenotypic variation despite lack of (species level) mitochondrial DNA monophyly and extremely low differentiation in other putatively neutral genetic markers.

Survey of flea infestation in cats and dogs in Western Andalusia, Spain: Seasonality and other risk factors for flea infestation

Medical and Veterinary Entomology, Volume 38, Issue 2, Page 244-251, June 2024.
This work supports the preference of the predominant flea species in pets for seasons with higher temperatures and lower percentages of rainfall. C. felis was the dominant flea species, whereas dogs exhibited a greater diversity of flea species. The number of female fleas was higher than males in all identified species and hosts.
