Data from: Interactions among morphotype, nutrition, and temperature impact fitness of an invasive fly.Dalila Rendon, Vaughn Walton, Gabriella Tait, Jessica Buser, Ivana Lemos Souza, Anna Wallingford, Greg Loeb & Jana Lee
Invasive animals depend on finding a balanced nutritional intake to colonize, survive, and reproduce in new environments. This can be especially challenging during situations of fluctuating cold temperatures and food scarcity, but phenotypic plasticity may offer an adaptive advantage during these periods. We examined how lifespan, fecundity, pre-oviposition periods, and body nutrient contents were affected by dietary protein and carbohydrate (P:C) ratios at variable low temperatures in two morphs (winter morphs WM and summer morphs...
Data from: The value of trophic interactions for ecosystem function: dung beetle communities influence seed burial and seedling recruitment in tropical forestsHannah M. Griffiths, Richard D. Bardgett, Julio Louzada & Jos Barlow
Anthropogenic activities are causing species extinctions, raising concerns about the consequences of changing biological communities for ecosystem functioning. To address this, we investigated how dung beetle communities influence seed burial and seedling recruitment in the Brazilian Amazon. First, we conducted a burial and retrieval experiment using seed mimics. We found that dung beetle biomass had a stronger positive effect on the burial of large than small beads, suggesting that anthropogenic reductions in large-bodied beetles will...
Data from: Inaccuracy of venous point-of-care glucose measurements in critically ill patients: a cross-sectional studyAdriano Jose Pereira, Thiago Domingos Corrêa, Francisca Pereira De Almeida, Rodrigo Octavio Deiberato, Michelle Dos Santos Lobato, Nelson Akamine, Eliézer Silva, Alexandre Biasi Cavalcanti & Rodrigo Octávio Deliberato
Introduction: Current guidelines and consensus recommend arterial and venous samples as equally acceptable for blood glucose assessment in point-of-care devices, but there is limited evidence to support this recommendation. We evaluated the accuracy of two devices for bedside point-of-care blood glucose measurements using arterial, fingerstick and catheter venous blood samples in ICU patients, and assessed which factors could impair their accuracy. Methods: 145 patients from a 41-bed adult mixed-ICU, in a tertiary care hospital were...
1. Experimental studies linking community composition to functioning are typically confined to small and closed micro- or mesocosms. Such restricted conditions may affect both species’ biology and their environment. Yet, targeting simple features in the behaviour of species may circumvent these constraints. Focusing on ecological functions provided by dung beetles, we test whether large, open-top cages – MESOCLOSURES – will intercept the flight trajectories of beetles, thereby allowing manipulation of local community composition. 2. MESOCLOSURES...
Data from: Canals as invasion pathways in tropical dry forest and the need for monitoring and managementMatheus S. Asth, Renato G. Rodrigues & Rafael D. Zenni
Linear infrastructure intrusions are common around the world to meet the needs of a growing and interconnected human population. The implementation of linear infrastructures involves numerous forms and mechanisms of land-use transformation that can facilitate and serve as pathways to the spread of invasive non-native species. However, the type and intensity of land transformations change over time and this can affect the frequency and intensity in which linear infrastructures route the spread of invasive species....
1. The extent (or lack) of phylogenetic signal for key ecological traits reveals the role of evolutionary processes on present-day ecosystem function and hints on future ecological trends under climate change scenarios. This approach has been applied to South American tropical moist forests, but not to the highly threatened seasonally dry tropical forests (SDTF), despite acknowledgement of their unique evolutionary history. To fill this knowledge gap, we investigated the legacy of evolutionary processes on vital...
