Behavioral effects of chronic stress in Carioca High- and Low-conditioned Freezing rats

Yury Lages, Silvia Maisonnette, Beatriz Marinho, Flávia Rosseti, Thomas Krahe & J. Landeira-Fernandez
Chronic unpredictable mild stress (CUMS) is a widely used model to study stress-coping strategies in rodents. Different factors have been shown to influence whether animals adopt passive or active coping responses to CUMS. Individual adaptation and susceptibility to the environment seem to play a critical role in this process. To further investigate this relationship, we examined the effects of CUMS on Carioca high- and low-conditioned freezing rats (CHF and CLF, respectively), bidirectional lines of animals...

Data from: Visualizing mineralization processes and fossil anatomy using synchronous synchrotron X-ray fluorescence and X-ray diffraction mapping

Fossils, including those that occasionally preserve decay-prone soft-tissues, are mostly made of minerals. Accessing their chemical composition provides unique insight into their past biology and/or the mechanisms by which they preserve, leading to a series of developments in chemical and elemental imaging. However, the mineral composition of fossils, particularly where soft-tissues are preserved, is often only inferred indirectly from elemental data, while X-ray diffraction that specifically provides phase identification received little attention. Here, we show...

Time of activity is a better predictor of the distribution of a tropical lizard than pure environmental temperatures

Gabriel Henrique De Oliveira Caetano, Juan Carlos Santos, Leandro Godinho, Vitor Cavalcante, Luisa Viegas, Pedro Campelo, Lidia Martins, Alan De Oliveira, Júlio Alvarenga, Helga Wiederhecker, Verônica De Novaes E Silva, Fernanda Werneck, Donald Miles, Guarino Colli & Barry Sinervo
Environmental temperatures influence ectotherms’ physiology and capacity to perform activities necessary for survival and reproduction. Time available to perform those activities is determined by thermal tolerances and environmental temperatures. Estimates of activity time might enhance our ability to predict suitable areas for species’ persistence in face of climate warming, compared to the exclusive use of environmental temperatures, without considering thermal tolerances. We compare the ability of environmental temperatures and estimates of activity time to predict...

Evolution of altitudinal migration in passerines is linked to diet

Claudie Pageau, Mariana M. Vale, Marcio Argollo De Menezes, Luciana Barçante, Mateen Shaikh, Maria Alice Alves & Matthew W. Reudink
Bird migration is typically associated with a latitudinal movement from north to south and vice versa. However, many bird species migrate seasonally with an upslope or downslope movement in a process termed altitudinal migration. Globally, 830 of the 6579 Passeriformes species are considered altitudinal migrants and this pattern has emerged multiple times across 77 families of this order. Recent work has indicated an association between altitudinal migration and diet, but none have looked at diet...

A blueprint for securing Brazil's marine biodiversity and supporting the achievement of global conservation goals

Aim: As a step towards providing support for an ecological approach to strengthening marine protected areas (MPAs) and meeting international commitments, this study combines cumulative impact assessment and conservation planning approach to undertake a large-scale spatial prioritisation. Location: Exclusive Economic Zone (EEZ) of Brazil, Southwest Atlantic Ocean Methods: We developed a prioritisation approach to protecting different habitat types, threatened species ranges, and ecological connectivity, while also mitigating the impacts of multiple threats on biodiversity. When...

Aim The introduction of aquatic non-indigenous species (ANS) has become a major driver for global changes in species biogeography. We examined spatial patterns and temporal trends of ANS detections since 1965 to inform conservation policy and management. Location Global Methods We assembled an extensive dataset of first records of detection of ANS (1965-2015) across 49 aquatic ecosystems, including the i) year of first collection, ii) population status and iii) potential pathway(s) of introduction. Data were...
