Holocene climate changes explain the spatial pattern in genetic diversity in populations of Cyperus papyrus from Southeast Africa wetlands

Elias Luís Maxombe, Lucas Vieira & Rosane Collevatti
Wetlands are one of the most threatened ecosystems in the world because more than 70% of the area worldwide has been lost since 1900. Wetland plant species rely greatly on water for seeds and propagules, which may lead to a downstream unidirectional dispersal and accumulation of genetic diversity downstream. However, several species show no support for unidirectional genetic diversity, revealing the complexity of population dynamics and gene flow in wetlands. Here, we used microsatellite loci...

Exceptions to the rule: Relative roles of time, diversification rates and regional energy in shaping the inverse latitudinal diversity gradient

Felipe Cerezer, Antonin Machac, Thiago Rangel & Cristian Dambros
Aim: Inverse latitudinal diversity gradients (i-LDG), whereby regional richness peaks outside the tropics, have rarely been investigated and their causes remain unclear. Here, we investigate three prominent explanations, postulating that species-rich regions have had (1) longer time to accumulate species, (2) faster diversification, and (3) more energy to support more diverse communities. These mechanisms have been shown to explain the tropical megadiversity, and we examine whether they can also explain i-LDG. Location: Global Time period:...

Studying species interactions in nature often requires elaborate logistics and intense fieldwork. The difficulties in such task might hinder our ability to answer questions on how biotic interactions change with the environment. Fortunately, a workaround to this problem lies within scientific collections. For some animals, the inspection of preserved specimens can reveal the scars of past antagonistic encounters, such as predation attempts. A common defensive behaviour that leaves scars on animals is autotomy, the loss...

Amphbian larvae survey at Emas National Park, Brazil (2012/2013, 2014/2015, 2017/2018)

Fausto Nomura, Ingrid Beatriz Ferreira Paixão & Gabriela Alves-Ferreira
Multiple factors contribute to explaining the composition and structure of communities and the niche is still the most used theory to describe how organisms interact with such factors to generate biological communities’ patterns. Both biotic and abiotic aspects of the environment along with the geographic space interact in complex ways with the behavior and physiological tolerance of organisms to structure a community. In this study, we tested the potential effects of the environment and space...

Tangency and multiple factors of violence against lecturer: nuances of the experience in pedagogical practices in health education

Angela Gilda Alves, Flaviane Cristina Rocha César, Maria Alves Barbosa, Lizete Malagoni de Almeida Cavalcante Oliveira, Dolors Rodríguez-Martín, Edinamar Aparecida Santos da Silva, Johnatan Martins Sousa & Sara Oliveira Souza
ABSTRACT Objective: to identify factors that lead the teacher to experience violence in their pedagogical practice in health education. Method: research with a qualitative approach, based on the Grounded Theory, conducted with 11 professors of the nursing course of a public university in the central region of Brazil in 2020 and 2021. Online semi-structured interviews were analyzed partially in the light of the Constructivist Grounded Theory. Results: factors that lead lecturer to experience violence are...

Evolutionary history and precipitation seasonality shape niche overlap in Neotropical bat-plant pollination networks

Luisa Fernanda Lievano-Latorre, Isabela Varassin & Thais Zanata
Species interactions are one dimension of the niche, and niche overlap arises when two species share an interaction partner. In pollination systems, environmental and biotic factors impact the niche overlap. Here we explored the effects of climate seasonality, plant and bat richness, morphological traits, and phylogenetic distance in shaping the niche overlap of Neotropical bat-plant pollination networks. For that, we used a dataset of 22 bat-plant pollination networks in the Neotropical region. We measured niche...
