Dennis was born on 2 May 1985 in Cochabamba, Department of Cochabamba, Bolivia. He is survived by his wife Zulema, two sons Daniel and Alejandro, his parents Jaime and Maria Elena, and sisters Nohelia and Anahis. Dennis attended Universidad Mayor de San Simón in Cochabamba, Bolivia and completed a Bachelor's degree in Biology in 2015. He completed his undergraduate thesis studying Bolivian bats entitled "Caracterización de refugios cavernícolas de murciélagos en el este del departamento de Santa Cruz, Bolivia" under Dr. Luis F. Aguirre. Prior to graduation, Dennis was hired as a research biologist with the Centro de Investigación de Recursos Acuáticos (CIRA) at Universidad Autónoma del Beni "Jose Balliván", in Trinidad, Beni, Bolivia. In the beginning of his tenure at CIRA, Dennis' work was largely focused on fishes and aquatic ecology throughout the Bolivian Amazon, including integral work on Paiche (Arapaima gigas), freshwater rays (Myliobatiformes: Potamotrygonidae), algae, and community ecology of fishes. Most recently, Dennis was a co-founder and the first curator of the herpetology collection CIRA-one of only four herpetological collections in the country of Bolivia. Under Dennis' curation the CIRA collection has grown rapidly, has become known internationally, and now houses the largest representative collection of herpetological specimens from the Department of Beni. In addition to many specimens from

However, the information needed to evaluate such trends remains unstandardised and sparsely available for many taxonomic groups and habitats, including the cave-dwelling bats and cave ecosystems. We developed the DarkCideS 1.0 (https://darkcides.org/), a global database of bat caves and species synthesised from publicly available information and datasets. The DarkCideS 1.0 is by far the largest database for cave-dwelling bats, which contains information for geographical location, ecological status, species traits, and parasites and hyperparasites for 679 bat species are known to occur in caves or use caves in part of their life histories. The database currently contains 6746 georeferenced occurrences for 402 cave-dwelling bat species from 2002 cave sites in 46 countries and 12 terrestrial biomes. The database has been developed to be collaborative and open-access, allowing continuous data-sharing among the community of bat researchers and conservation biologists to advance bat research and comparative monitoring and prioritisation for conservation.

El unir esfuerzos en redes de interaccion ha sido una estrategia promovida fundamentalmente por el hecho de que las aproximaciones centralizadas de arriba hacia abajo (top-down) han fallado en llegar a los tomadores de decision y por lo tanto en alcanzar resultados tangibles (Bodin & Prell 2014). Mas aun, en Latinoamerica muchas iniciativas globales han tenido precisamente ese enfoque top-down, en que las politicas de conservacion eran dictadas por entidades que no viven las realidades locales, promueven poco o nada la comunicacion y colaboracion sur-sur, con la consecuente perdida de muchas oportunidades de conservacion local y efectiva (Rodriguez et al. 2007). La construccion de redes para la ...

However, studies on this subject have been focused mainly on medium and large mammals, while those on small mammals are scarce. Small mammals play important roles in maintaining ecological processes, such as the survival of several plant species. Phyllotis osilae is a phyllotine rodent, which functions as a potential seed disperser for Polylepis subtusalbida , a tree that is endemic and categorized as Vulnerable (VU) for Bolivia. The forests of P. subtusalbida are highly fragmented, with reforestation with introduced species such as Pinus radiata and Eucalyptus globulus . The question we pose for this study is: how does the home range of P. osilae vary between fragments of P. subtusalbida with different types of matrix (natural grassland and exotic tree plantations)? The study was carried out on four frag...

We incorporate and describe recent taxonomic changes and new records for the country made since the last list published in 2003. New records and taxonomic changes were considered only if they had verifiable evidence. To date, the list of mammals for the country includes 406 native species, belonging to 11 orders, 46 families and 196 genera, representing an increase of 51 species over the 2003 list. Among those added, 14 were new to science and have type localities in Bolivia. The most diverse orders were Rodentia (148 species), Chiroptera (138), Didelphimorphia (35) and Carnivora (27); a total of 25 species are endemic to Bolivia. In addition, 14 species of introduced mammals are listed. Additional records and taxonomic changes are expected as a result of biological inventories currently in execution, re-identification of specimens deposited in national and foreign mammal collections, and future taxonomic revisions.

INFLUENCE OF HUMAN ACTIVITIES ON BUTTERFLY COMMUNITIES OF Polylepis besseri FORESTS OF COCHABAMBA... more INFLUENCE OF HUMAN ACTIVITIES ON BUTTERFLY COMMUNITIES OF Polylepis besseri FORESTS OF COCHABAMBA - BOLIVIA La composicion de comunidades animales en bosques nativos es afectada por diferentes tipos de perturbacion antropogenica. Tal es el caso de los bosques nativos andinos de Polylepis besseri del Parque Nacional Tunari (PNT), San Miguel y Sacha Loma donde se realizo el estudio con el objetivo de medir la influencia de la actividad antropogenicas (agricola, ganadera, fragmentacion e introduccion de especies exoticas de pinos y eucaliptos) en las comunidades de mariposas. Este estudio se desarrollo desde fines del 2002 hasta principios del 2005, empleando trampas Van Someren Rydon y redes entomologicas manuales. En las tres zonas se registraron un total de 39 especies, donde el PNT fue mas diverso y Sacha Loma menos diverso. Los bosques de Sacha Loma y San Miguel tuvieron una similitud de especies superior al 70% y los bosques del PNT entre un 40 a 75% de similitud. Los patrones encontrados muestran que perturbaciones intermedias promueven una mayor diversidad de mariposas en bosques de Polylepis. Sin embargo, si estas perturbaciones se intensifican esta diversidad disminuira afectando principalmente a especies propias de bosques nativos. Palabras clave: mariposas, diversidad, perturbacion, Polylepis, Andes, Bolivia. ABSTRACT Composition of animal communities in native forests is affected by different types of human intervention. Such is the case of native Andean forests of Polylepis besseri located within the Tunari Nacional Park (PNT), at San Miguel and Sacha Loma. In these locations we wanted to evaluate the effect of some human activities (agriculture, cattle grazing,fragmentation and introduction of exotic plant species) on the butterfly communities. The study was carried out from 2002 to 2005 at those localities and to evaluate butterflies we used Van Someren Rydon traps and hand nets. In the three localities we registered a total of 39 species, being PNT the most diverse and Sacha Loma the least. The forests of Sacha Loma and San Miguel had a similarity in species over 70% and with forests at PNT about 40-75% respectively. The patterns found show, that intermediate disturbance promote a higher diversity of butterflies in Polylepis forests. However, if disturbance increases, the diversity decreases, affecting mainly species typical for native forests. Key words: butterflies, diversity, disturbance, Polylepis, You walk, Bolivia.

El conflicto entre las actividades humanas y los murciélagos vampiros (Desmodus rotundus) ha sido evidente en la Prepuna boliviana en las últimas décadas. Se han reportado frecuentes ataques al ganado caprino, lo que condujo a la aplicación de estrategias de control inadecuadas de las poblaciones del vampiro. Con el objetivo de aportar al manejo y mitigación del conflicto, se evaluó si la incidencia de ataques está asociada a factores como la distribución y la abundancia del ganado, la distancia de los corrales a los principales refugios de los vampiros, el tipo de hábitat y la abundancia relativa del vampiro. Los resultados sugieren que la incidencia de ataques decrece con la cantidad de ganado y con la distancia de los corrales a los refugios de los vampiros, y se incrementa con la abundancia relativa de vampiros en la zona. Por otro lado, la abundancia de vampiros está relacionada positivamente con la disponibilidad de refugios cercanos a sus áreas de forrajeo pero no as...
