Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

Journal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Education and Learning in Studies of Nationalism: Anderson and Weber in Focus

Nations and Nationalism, EarlyView.
ABSTRACT Scholars of nationalism have pointed to the importance of educational institutions for the dissemination of national identities and associated sentimental attachments, yet how nationalism is learned within these educational institutions has received little attention.

Whole genome sequencing of historical specimens from the world's largest fungal collection yields high‐quality assemblies

New Phytologist, EarlyView.
Summary High‐throughput molecular studies of museum specimens (museomics) have great potential in biodiversity research, but fungal historical collections have scarcely been examined, leading to no comprehensive methodological assessments. Here we present a whole genome sequencing (WGS) project conducted at the Fungarium of the Royal Botanic Gardens ...

CLIMATE AND SCALE IN ECONOMIC GROWTH [PDF]

This paper introduces new data on climatic conditions to empirical tests of growth theories. We find that, since 1960, temperate countries have converged towards high levels of income while tropical nations have converged towards various income levels ...

Repeatability, Genetic Variability and Importance of Forage Traits in Ecotypes of Brunswickgrass (Paspalum nicorae Parodi) via BLUP

Plant Breeding, EarlyView.
ABSTRACT This study estimated the repeatability of forage traits in 84 Paspalum nicorae ecotypes using six statistical methods and quantified the minimum number of harvests needed for effective selection. Multivariate analyses based on best linear unbiased prediction (BLUP) values were also performed to assess genetic variability, identify key traits ...

Thermal Safety Margins and Peak Leaf Temperatures Predict Vulnerability of Diverse Plant Species to an Experimental Heatwave

Plant, Cell &Environment, EarlyView.
ABSTRACT Extreme heat can push plants beyond their thermal safety margin (TSM) if maximum leaf temperature (Tleaf_max) exceeds leaf critical temperature (Tcrit). The TSM is potentially useful for assessing heat vulnerability across species but needs further validation, so we exposed 50 tree/shrub species in controlled glasshouses to a 6‐day heatwave ...

Trade‐offs in thermal response: Schizotetranychus brevisetosus winter eggs outperform summer eggs at low temperatures

Physiological Entomology, EarlyView.
We investigated maternal effects in Schizotetranychus brevisetosus (Tetranychidae), where females oviposit summer and winter eggs in response to photoperiod on evergreen hosts. Developmental rates of immature individuals increased linearly from 15°C to 35°C, but winter and summer eggs developed faster at low and high temperatures, respectively ...

Turf transplantation as a potential restoration technique in subtropical grasslands

Restoration Ecology, EarlyView.
Abstract Introduction Subtropical grasslands in southern Brazil suffer from ongoing degradation, while restoration initiatives of these ecosystems are still incipient. Turf transplantation appears as a promising approach for restoring these ecosystems.
