Influence of limnological zones on the spatial distribution of fish assemblages in three Brazilian reservoirs

Creator:: Becker, Bárbara, de Oliveira Sanches Galhardo, Bárbara, Macedo, Diego Rodrigues, Hughes, Robert M., Callisto, Marcos, and Santos, Gilmar B.
Abstract:: Reservoirs can have both positive and negative effects on differing fish species depending on the species concerned and reservoir morphology, flow regime, and basin location. We assessed the influence of limnological zones on the ichthyofauna of three large Neotropical reservoirs in two different river basins. We sampled fish through use...

Importance of environmental factors for the richness and distribution of benthic macroinvertebrates in tropical headwater streams

Creator:: Ferreira, Wander R., Ligeiro, Raphael, Macedo, Diego R., Hughes, Robert M., Kaufmann, Philip R., Oliveira, Leando G., and Callisto, Marcos
Abstract:: An understanding of the interactions among local environmental factors (e.g., physical habitat and water quality) and aquatic assemblages is essential to conserve biodiversity in tropical and subtropical headwater streams. We evaluated the relative importance of multiple physical and chemical habitat variables that influence the richness of Ephemeroptera, Plecoptera, and Trichoptera...

Is the diet of a typical shredder related to the physical habitat of headwater streams in the Brazilian Cerrado?

Creator:: Ferreira, Wander R., Ligeiro, Raphael, Macedo, Diego R., Hughes, Robert M., Kaufmann, Philip R., Oliveira, Leandro G., and Callisto, Marcos
Abstract:: Macroinvertebrates are important for processing leaf detritus in temperate streams, but studies about their role in tropical streams often present conflicting results. Via digestive tract analyses, we assessed the diets of Phylloicus sp. larvae (Trichoptera: Calamoceratidae), collected from streams of two southeastern Brazil river basins (Araguari, Sao Francisco). We classified...

The Altruism-Empathy-Perspective Connection: A Case Study of Human-Wildlife Interactions at Cintimini Wildlife Rehabilitaion Center, Corvallis, Oregon

Creator:: Freed, Kirsten S.
Abstract:: In the realms of psychology and sociology two new theoretical models have arisen to describe the forces influencing altruistic human behavior. The first Empathy-Altruism Hypothesis (EAH), by C.D. Batson. The second is the Conceptual Continuum of Altruism (CCA), by K.R. Monroe. Both models have proven to be highly useful in...

Using Biodiversity Distribution Data to Support Landscape Conservation and Management in Colombia

Creator:: Zárrate-Charry, Diego A.
Abstract:: Global biodiversity decline is primarily driven by habitat loss. Deforestation, the primary driver of terrestrial habitat loss, is increasing worldwide, with the most significant impact in the world biodiversity hotspots. Sadly, specific knowledge of such impacts in biodiversity-rich but data-poor countries are still unknown, and many national and regional narratives...

The relative influence of catchment and site variables on fish and macroinvertebrate richness in cerrado biome streams

Creator:: Macedo, Diego R., Hughes, Robert M., Ligeiro, Raphael, Ferreira, Wander R., Castro, Miriam A., Junqueira, Nara T., Oliveira, Deborah R., Firmiano, Kele R., Kaufmann, Philip R., Pompeu, Paulo S., and Callisto, Marcos
Abstract:: Landscape and site-scale data analyses aid the interpretation of biological data and thereby help us develop more cost-effective natural resource management strategies. Our study focused on environmental influences on stream assemblages and we evaluated how three classes of environmental variables (geophysical landscape, land use and cover, and site habitat), influence...

Defining quantitative stream disturbance gradients and the additive role of habitat variation to explain macroinvertebrate taxa richness

Creator:: Ligeiro, Raphael, Hughes, Robert M., Kaufmann, Philip R., Macedo, Diego R., Firmiano, Kele R., Ferreira, Wander R., Oliveira, Deborah, Melo, Adriano S., and Callisto, Marcos
Abstract:: Most studies dealing with the use of ecological indicators and other applied ecological research rely on some definition or concept of what constitutes least-, intermediate- and most-disturbed condition. Currently, most rigorous methodologies designed to define those conditions are suited to large spatial extents (nations, ecoregions) and many sites (hundreds to...

Development of a benthic macroinvertebrate multimetric index (MMI) for Neotropical Savanna headwater streams

Creator:: Macedo, Diego R., Hughes, Robert M., Ferreira, Wander R., Firmiano, Kele R., Silva, Deborah R. O., Ligeiro, Raphael, Kaufmann, Philip R., and Callisto, Marcos
Abstract:: Assessing the ecological impacts of anthropogenic pressures is a key task in environmental management. Multimetric indices (MMIs), based on aquatic assemblage responses to anthropogenic pressures, have been used increasingly throughout the world. The MMI approach is a low-cost, rapid field method that produces an aquatic condition index that responds precisely...

Chronic leaf harvesting reduces reproductive success of a tropical dry forest palm in northern Mexico

Creator:: Lopez-Toledo, Leonel, Perez-Decelis, Angeles, Macedo-Santana, Franceli, Cuevas, Eduardo, and Endress, Bryan A.
Abstract:: Palm leaves represent one of the most important non-timber forest products in tropical and subtropical regions. Brahea aculeata is an endemic palm of northwest Mexico, whose leaves are intensively exploited for roof thatch and handcrafts. As part of a long-term defoliation experiment, we evaluated the effects of different leaf harvest...

Transkingdom network reveals bacterial players associated with cervical cancer gene expression program

Abstract:: Cervical cancer is the fourth most common cancer in women worldwide with human papillomavirus (HPV) being the main cause the disease. Chromosomal amplifications have been identified as a source of upregulation for cervical cancer driver genes but cannot fully explain increased expression of immune genes in invasive carcinoma. Insight into...
