Carter, Elena Rodriguez-Vieitez, Agneta Nordberg, Luc Pellerin, Pedro Rosa-Neto, Douglas Teixeira Leffa & Eduardo R. Zimmer
Objective: To perform a systematic review and meta-analysis to determine whether fluid and imaging astrocyte biomarkers are altered in Alzheimer's disease (AD). Methods: PubMed and Web of Science databases were searched for articles reporting fluid or imaging astrocyte biomarkers in AD. Pooled effect sizes were determined with mean differences (SMD) using the Hedge’s G method with random-effects to determine biomarker performance. Adapted questions from QUADAS-2 were applied for quality assessment. A protocol for this study...
Data from: Reverse diel vertical movements of oceanic manta rays off the northern coast of Peru and implications for conservationSamantha Andrzejaczek, Robert Schallert, Kerstin Forsberg, Natalie Arnoldi, Mariano Cabanillas, Wilmer Purizaca & Barbara Block
An understanding of the vertical movements of elasmobranchs across their range is crucial to defining critical habitat use, its overlap with anthropogenic activities, and subsequently managing such interactions. In this study, satellite telemetry was used to investigate the vertical habitat use of three oceanic manta rays (Mobula birostris) tagged on the northern coast of Peru. All three oceanic mantas exhibited patterns of reverse diel vertical migration, where vertical movements were significantly deeper at night than...

Evolutionary tradeoffs between male secondary sexual traits revealed by a phylogeny of the hyperdiverse tribe Eumaeini (Lepidoptera: Lycaenidae)Wendy A. Valencia-Montoya, Tiago B. Quental, João Filipe R. Tonini, Gerard Talavera, James D. Crall, Gerardo Lamas, Robert C. Busby, Ana Paula S. Carvalho, Ana B. Morais, Nicolás Oliveira Mega, Helena Piccoli Romanowski, Marjorie A. Liénard, Shayla Salzman, Melissa R. L. Whitaker, Akito Y. Kawahara, David J. Lohman, Robert K. Robbins & Naomi E. Pierce
Male butterflies in the hyperdiverse tribe Eumaeini possess an unusually complex and diverse repertoire of secondary sexual characteristics involved in pheromone production and dissemination. Maintaining multiple sexually selected traits is likely to be metabolically costly, potentially resulting in trade-offs in the evolution of male signals. However, a phylogenetic framework to test hypotheses regarding the evolution and maintenance of male sexual traits in Eumaeini has been lacking. Here, we infer a comprehensive, time-calibrated phylogeny from 379...
The Atlantic spotted dolphin (Stenella frontalis) is endemic to tropical, subtropical, and warm temperate waters of the Atlantic Ocean. Throughout its distribution, both geographic distance and environmental variation may contribute to population structure of the species. In this study we follow a seascape genetics approach to investigate population differentiation of Atlantic spotted dolphins based on a large worldwide dataset and the relationship with marine environmental variables. The results revealed that the Atlantic spotted dolphin exhibits...
Influence of past and current factors on the beta diversity of coastal lagoon fish communities in South AmericaTaís De Fátima Ramos Guimarães, Ana Cristina Petry, Sandra Maria Hartz & Fernando Gertum Becker
Aim: We aimed to assess the relative influence of past (Quaternary paleodrainage characteristics) and current factors on the beta diversity of freshwater fishes in coastal lagoons and explore the main processes involved. Location: Atlantic coast of South America. Taxon: Fishes (173 species) Methods: We built a dataset of species occurrence in 129 lagoons across eight freshwater ecoregions of the world (FEOWs) located between latitudes 0° and 36° and calculated beta diversity (βjac) and its turnover...
Genomic population reveals potential micro-refuge and riverine barriers in southern South American grasslands: An example in nightshade: VCF file (16,128 SNPs)Giovanna Giudicelli
Aim: Pleistocene climate oscillations influenced the species distribution and genetic diversity in South American grasslands. Paleoclimate changes promoted expansion and contraction cycles that could lead to fragmentation and isolation of evolutionary lineages in refuges. Moreover, sea-level oscillations led to defrosting in some areas, affecting the river dynamics and influencing South American species' evolutionary history. This study aimed to infer which evolutionary processes most influenced the lineages differentiation in South American nightshade Petunia inhabiting subtropical grasslands...
Ground-foraging ant communities in invaded (by Hovenia dulcis) and non-invaded Atlantic Forest sites, and ant-H. dulcis diaspore interactionsLuciana Podgaiski, William Drose, Mauricio Almerão & Gabriel Guimarães
Biological invasions are a worldwide threat to biodiversity. Invasive species can affect biodiversity in many ways, such as by altering habitat properties and structure to which native species are dependent. Recipient communities that have mutualistic interactions with invasive species, such as seed dispersal mutualistic networks, are more vulnerable to invasion. The japanese raisin tree, Hovenia dulcis Thunberg (Rhamnaceae), is an example of a successful invasive tree in the Brazilian Atlantic Forest, where it alters plant...
The Healthy Urban Mobility (HUM) project was a study to understand the impact of everyday (im)mobility on health and wellbeing with a variety of social groups living in different neighbourhoods in Brazil and the UK, and also to explore the potential for participatory mobilities planning with local communities to support and develop solutions for healthy urban mobility.
The gain or loss of anatomical features is an important mechanism of morphological evolution and ecological adaptation. Dental anomalies –the loss or gain of teeth– are widespread and a potential source of craniodental specialization among mammals, yet their macroevolutionary patterns have been rarely explored. We present the first phylogenetic comparative study of dental anomalies across the second largest mammal Order, Chiroptera (bats). We conducted an extensive literature review and surveyed a large sample of museum...
Functional biogeography of Neotropical moist forests: trait-climate relationships and assembly patterns of tree communitiesBruno Pinho, Marcelo Tabarelli, Cajo Ter Braak, S. J. Wright, Victor Arroyo-Rodriguez, Maíra Benchimol, Bettina Engelbrecht, Simon Pierce, Peter Hietz, Bráulio Santos, Carlos Peres, Sandra Müller, Ian Wright, Frans Bongers, Madelon Lohbeck, Ülo Niinemets, Martijn Slot, Steven Jansen, Davi Jamelli, Renato Augusto Ferreira De Lima, Nathan Swenson, Richard Condit, Jos Barlow, Ferry Slik, Manuel Hernández-Ruedas … & Felipe Melo
Aim: Here we examine the functional profile of regional tree species pools across the latitudinal distribution of Neotropical moist forests, and test trait-climate relationships among local communities. We expected opportunistic strategies (acquisitive traits, small seeds) to be overrepresented in species pools further from the equator due to long-term instability, but also in terms of abundance in local communities in currently wetter, warmer and more seasonal climates. Location: Neotropics. Time period: Recent. Major taxa studied: Trees....
Objective: The objectives of this study were to measure the global impact of the pandemic on the volumes for intravenous thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with two control 4-month periods. Methods: We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by their ICD-10 codes and/or classifications in...
Decline of the brown-throated sloth (Bradypus variegatus Schinz, 1825) in an Atlantic Forest protected areaGabriel Lopes, Gabriel Penido, Neander Heming & Luisa Diele-Viegas
Estimates on demographic parameters altogether with social factors are integral and can be very useful to assess the risks that a population may face in the future. Rescue operations may provide a unique opportunity to gather data on individuals of an area and thus provide population information. Animal rescue data provided by the Rio de Janeiro Botanical Garden fauna team were used to understand the structure of a population of Bradypus variegatus in an urban...
Determining herbage intake is pivotal for studies on grazing ecology. Direct observation of animals allows describing the interactions of animals with the pastoral environment along the complex grazing process. The objectives of the study were to evaluate the reliability of the continuous bite monitoring (CBM) method in determining herbage intake in grazing sheep compared to the standard double-weighing technique (DW) method during 45-min feeding bouts; evaluate the degree of agreement between the two techniques; and...
