A molecularly based phylogeny reconstruction of mushroom corals (Scleractinia: Fungiidae) with taxonomic consequences and evolutionary implications for life history traits Naturalis
Gittenberger, A.; Reijnen, B.T.; Hoeksema, B.W..
The phylogenetic relationships of the Fungiidae, a family of predominantly free-living, zooxanthellate, reef corals, were studied by sequencing a part of the mitochondrial Cytochrome Oxidase I (COI) and the complete ribosomal Internal Transcribed Spacers (ITS) I & II of specimens from various locations in the Indo- West Pacific. Some sequences were retrieved by using fungiidspecific primers on DNA-extracts from parasitic gastropods living with these corals. The analyses were performed both including and excluding intraspecific variation to investigate the potential effect of saturation. Even though the present molecular phylogeny reconstructions largely reflect those based on morphological characters, there are some distinct differences. Three major...

La pluriactividad como estrategia de reproducción socioeconómica de las unidades domésticas campesinas (UDC) en San Pablo Actipan, Municipio de Tepeaca, Puebla. Colegio de Postgraduados
Palomares Licona, Angélica.
El universo rural en los últimos años ha sufrido diversas transformaciones en ámbitos sociales, económicos, culturales, ecológicos, políticos; esto ha implicado en algunos casos la sustitución y rezago de formas tradicionales rurales de producción, por ejemplo, por aquellas que podrían considerarse actuales y modernas. Sin embargo, también existe la combinación de estas formas de vida rural con aquellas que provienen del universo urbano y que de alguna forma transforman a la primera debido entre otros factores, a su cercanía. La localidad de San Pablo Actipan, perteneciente al Municipio de Tepeaca, Puebla, muestra características interesantes no solo a lo previamente señalado; entre lo más destacable se encuentra la diversidad de actividades agrícolas y no...

Temporal differences in breeding site use between tits and mice OAK
Suzuki, Kei K.; Yoshida, Tomoya; Yamane, Yutaka; Shimamoto, Tatsuki; Furukawa, Ryuji G.; Yanagawa, Hisashi.
Describing the interactions among cavity breeders is key to understanding their breeding ecology. In this study the temporal difference in cavity use between the great tit, Parus major (Linnaeus, 1758) and the small Japanese field mice, Apodemus argenteus (Temminck, 1845) is investigated, as a first step for clarifying the interaction between bird and mammal cavity breeders. Forty-seven nest boxes were installed on tree trunks in two urban forests of Hokkaido Island, Japan, and the breeding nests of tits and mice were found in 34 and 11 boxes, respectively. The tits used the nest boxes throughout the breeding season, from May to July. In contrast, mice breeding nests were found in the last half of the breeding season, from July to October. Our results...

The paradigmatic field of usage of the theoretical category of pluriactivity in Brazil Ciência Rural
Silva,Márcia Danielly Cavalcanti; Fiúza,Ana Louise De Carvalho; Pinto,Neide Maria de Almeida.
ABSTRACT: The lack of interpretive convergence around an analytical category or concept generates a field of disputes around the understanding of a certain phenomenon. This is also the case with “pluriactivity”, on which there remain interpretive divergences derived from its conception. This research aims to identify the interpretive tendencies that are gaining traction in Brazil. For that, the research used as a database the Brazilian Digital Library of Theses and Dissertations (BDTD - “Biblioteca Digital Brasileira de Teses e Dissertações”), since this type of database compiles and updates the state of the art on the subject. The research universe consisted of 115 dissertations and theses were systematized and analyzed using IRAMUTEQ software. Results...
