Pervasive human-driven decline of life on Earth points to the need for transformative change.

The human impact on life on Earth has increased sharply since the 1970s, driven by the demands of a growing population with rising average per capita income. Nature is currently supplying more materials than ever before, but this has come at the high cost of unprecedented global declines in the extent and integrity of ecosystems, distinctness of local ecological communities, abundance and number of wild species, and the number of local domesticated varieties. Such changes reduce vital benefits that people receive from nature and threaten the quality of life of future generations. Both the benefits of an expanding economy and the costs of reducing nature's benefits are unequally distributed. The fabric of life on which we all depend-nature and its contributions to people-is unravelling rapidly. Despite the severity of the threats and lack of enough progress in tackling them to date, opportunities exist to change future trajectories through transformative action. Such action must begin immediately, however, and address the root economic, social, and technological causes of nature's deterioration.

Drivers potentially influencing host-bat fly interactions in anthropogenic neotropical landscapes at different spatial scales.

The anthropogenic modification of natural landscapes, and the consequent changes in the environmental conditions and resources availability at multiple spatial scales can affect complex species interactions involving key-stone species such as bat-parasite interactions. In this study, we aimed to identify the drivers potentially influencing host-bat fly interactions at different spatial scales (at the host, vegetation stand and landscape level), in a tropical anthropogenic landscape. For this purpose, we mist-netted phyllostomid and moormopid bats and collected the bat flies (streblids) parasitizing them in 10 sites representing secondary and old growth forest. In general, the variation in fly communities largely mirrored the variation in bat communities as a result of the high level of specialization characterizing host-bat fly interaction networks. Nevertheless, we observed that: (1) bats roosting dynamics can shape bat-streblid interactions, modulating parasite prevalence and the intensity of infestation; (2) a degraded matrix could favor crowding and consequently the exchange of ectoparasites among bat species, lessening the level of specialization of the interaction networks and promoting novel interactions; and (3) bat-fly interaction can also be shaped by the dilution effect, as a decrease in bat diversity could be associated with a potential increase in the dissemination and prevalence of streblids.

EFFECTS OF "SWIM WITH THE TURTLES" TOURIST ATTRACTIONS ON GREEN SEA TURTLE (CHELONIA MYDAS) HEALTH IN BARBADOS, WEST INDIES.

Along the West Coast of Barbados a unique relationship has developed between endangered green sea turtles (Chelonia mydas) and humans. Fishermen began inadvertently provisioning these foraging turtles with fish offal discarded from their boats. Although initially an indirect supplementation, this activity became a popular attraction for visitors. Subsequently, demand for this activity increased, and direct supplementation or provisioning with food began. Food items offered included raw whole fish (typically a mixture of false herring [Harengula clupeola] and pilchard [Harengula humeralis]), filleted fish, and lesser amounts of processed food such as hot dogs, chicken, bread, or various other leftovers. Alterations in behavior and growth rates as a result of the provisioning have been documented in this population. The purpose of this study was to determine how tourism-based human interactions are affecting the overall health of this foraging population and to determine what potential health risks these interactions may create for sea turtles. Juvenile green sea turtles (n=29) were captured from four sites off the coast of Barbados, West Indies, and categorized into a group that received supplemental feeding as part of a tour (n=11) or an unsupplemented group (n=18) that consisted of individuals that were captured at sites that did not provide supplemental feeding. Following capture, a general health assessment of each animal was conducted. This included weight and morphometric measurements, a systematic physical examination, determination of body condition score and body condition index, epibiota assessment and quantification, and clinical pathology including hematologic and biochemical testing and nutritional assessments. The supplemented group was found to have changes to body condition, vitamin, mineral, hematologic, and biochemical values. Based on these results, recommendations were made to decrease negative behaviors and health impacts for turtles as a result of this provisioning.

Nivel de actividad física y motivos que llevan a un grupo de adultos de la UBA Ramajal a practicarlo / Level of physical activity and the reasons why a group of adults of the basic attention unit, Ramajal, Bogotá, end up practicing it

El objeto de esta investigación es identificar y describir el nivel de actividad física y los motivos que llevanpracticarla en un grupo de adultos de la Unidad Básica de Atención, Ramajal, Bogotá, año 2001. Se utilizó un diseño cuantitativo de tipo descriptivo exploratorio que se realizó con 37 personas que integran el grupo Vida en el Nuevo Milenio, que practicaban actividad física por un tiempo mayor a tres meses en la UBA Ramajal de Bogotá. Para el desarrollo de esta investigación se utilizó un instrumento denominado Encuesta sobre actividad física y salud diseñado por el programa Muévete Bogotá del Instituto de Recreación y Deporte con el fin de identificar el nivel de actividad física del grupo, a su vez, se diseñaron nueve preguntas; estas preguntas permitieron identificar y describir los motivos que tiene el grupo para la practica de la actividad física. Se encontró que los participantes estaban en una fase de mantenimiento de la actividad física entre niveles de irregular a regularmente activos; igualmente, se identificaron motivos relacionados con categorías de salud, social e identidad, para la práctica de actividad física en sus diferentes etapas.

The purpose of this research is to identify and to describe the level of physical activity and the reasons thatmotivate its practice within a group of adults of the Basic Attention Unit (Unidad Básica de Atención), Ramajal, Bogotá, year 2001. A quantitative exploratory descriptive design was carried out with 37 persons who are members of the group called Life in the New Millennium (Vida en el Nuevo Milenio) and who were exercising physically for over three months in the UBA Ramajal of Bogotá. In this research a mechanism called Survey about physical activity and health was designed by the program Move Bogotá Move (Muévete Bogotá) of the City's Recreation and Sports Institute (Instituto de Recreación y Deporte), with the aim of identifying the level of physical activity of the group. Also, nine questions...

Consumo alimentar, atividade física e percepçäo da aparência corporal em adolescentes / Consumption of food, physical activity and perception of body aspect on adolescent

Para conhecer os padröes de consumo alimentar, os estágio de comportamento relativos à atividade física e as características antropométricas em uma populaçäo de adolescentes segundo a auto-percepçäo da aparência corporal foram avaliadas 28 adolescentes do sexo feminino de 14 a 17 anos de idade (x = 16,16 ñ 0,83) agrupadas de acordo com a auto-avaliaçäo da aparência coprporal em : G1- gorda, G2- peso normal e, G3- magra. Para estabelecer o consumo alimentar diário utilizou-se o registro alimentar de quatro dias. As variáveis antropométricas medidas foram peso, estatura, adiposidade mediante a média de sete dobras cutâneas e o índice de massa corporal. A maturaçäo sexual foi estabelecida por auto-avaliaçäo de acordo com os estágios de Tanner (pêlos públicos x = 5,5 ñ 0,9 e mamas x = 5,0 ñ 0,5). A análise estatística utilizada foi Anova Oneway, com post-hoc Scheffé. O nível de significância adotado foi p < .01. O grupo ''gorda'' apresentou valores maiores porém näo significantes de peso, estatura e IMC e valores significativamente mais altos de adiposidade que os demais grupos. O consumo de energia foi menor no grupo ''gorda'' em relaçäo aos demais e no ''normal'' em relaçäo ao ''magra''. Outro fator da ingestäo do grupo ''gorda'' é o resultado apresentado na auto-avaliaçäo do peso corporal, que pode estar interferindo na reduçäo da ingestäo alimentar das adolescentes objetivando controlar o peso considerado alto. No comportamento relativo à atividade física, a maioria das adolescentes näo parece ser ativa já que se encontram no estágio pré contemplativo

La seguridad humana en Bolivia: percepciones políticas, sociales y economicas de los bolivianos de hoy / The human security in Bolivia: politics, socials and economics perceptions of bolivians of today

Este informe sobre seguridad humana en Bolivia pretende realizar un analisis de la cotidianidad de la poblacion. Es una primera fotografia acerca de como perciben los bolivianos temas relativos a la seguridad humana. Se analizo cual es la percepcion que tienen de la politica y de su seguridad economica, personal, comunitaria y familiar. Tambien se atendio a como perciben su seguridad en salud, alimentacion y en relacion con el medio ambiente. El Informe se realizó a partir de una encuesta sobre Seguridad Humana que, adecuada a Bolivia, siguio las principales pautas conceptuales y métodologicas del Informe que sobre Seguridad Humana patrocino el PNUD en 1994
