Temporal and spatial variation of richness and abundance of the community of birds in the Pantanal wetlands of Nhecolandia (Mato Grosso do Sul, Brazil)
(2017)The Pantanal wetlands represent one of the largest flood plains in the World, with extreme climatic variations between dry and wet seasons. The area shelters a high diversity of habitats, representing the main formations ... -

Temporal patterns of Deepwater Horizon impacts on the benthic infauna of the northern Gulf of Mexico continental slope
(2017)The Deepwater Horizon oil spill occurred in spring and summer 2010 in the northern Gulf of Mexico. Research cruises in 2010 (approximately 2-3 months after the well had been capped), 2011, and 2014 were conducted to determine ... -

The genetic legacy of 50 years of desert bighorn sheep translocations
(2019)Conservation biologists have increasingly used translocations to mitigate population declines and restore locally extirpated populations. Genetic data can guide the selection of source populations for translocations and ... -

The Lysine Demethylase dKDM2 Is Non-essential for Viability, but Regulates Circadian Rhythms in Drosophila
(2018)Post-translational modification of histones, such as histone methylation controlled by specific methyltransferases and demethylases, play critical roles in modulating chromatin dynamics and transcription in eukaryotes. ... -

The Many Dimensions of Diet Breadth: Phytochemical, Genetic, Behavioral, and Physiological Perspectives on the Interaction between a Native Herbivore and an Exotic Host
(2016)From the perspective of an herbivorous insect, conspecific host plants are not identical, and intraspecific variation in host nutritional quality or defensive capacity might mediate spatially variable outcomes in plant-insect ... -

The mismatch in distributions of vertebrates and the plants that they disperse
(2019)Little is known about how mutualistic interactions affect the distribution of species richness on broad geographic scales. Because mutualism positively affects the fitness of all species involved in the interaction, one ... -

The Molecular Chaperone DnaK Is a Source of Mutational Robustness
(2016)Molecular chaperones, also known as heat-shock proteins, refold misfolded proteins and help other proteins reach their native conformation. Thanks to these abilities, some chaperones, such as the Hsp90 protein or the ... -

The path back: oaks (Quercus spp.) facilitate longleaf pine (Pinus palustris) seedling establishment in xeric sites
(2016)Understanding plant-plant facilitation is critical for predicting how plant community function will respond to changing disturbance and climate. In longleaf pine (Pinus palustris Mill.) ecosystems of the southeastern United ... -

The population genetic structure of Corythucha ciliata (Say) ( Hemiptera: Tingidae) provides insights into its distribution and invasiveness
(2017)Corythucha ciliata ( Say), an invasive pest originating from North America, causes severe damage on sycamore trees. However, little is known about the population genetics and evolutionary forces underlying the invasiveness ... -

The Role of Apoptotic Signaling in Axon Guidance
(2018)Navigating growth cones are exposed to multiple signals simultaneously and have to integrate competing cues into a coherent navigational response. Integration of guidance cues is traditionally thought to occur at the level ... -

The soil mosaic hypothesis: a synthesis of multi-trophic diversification via soil heterogeneity
(2017)Myriad unexplored mechanisms potentially drive ecological speciation and could help explain global variation in diversity. Here, we develop a novel hypothesis focused on variation in biotic, chemical, and physical properties ... -

The Value of Native Plants and Local Production in an Era of Global Agriculture
(2017)For addressing potential food shortages, a fundamental tradeoff exists between investing more resources to increasing productivity of existing crops, as opposed to increasing crop diversity by incorporating more species. ... -

The WAGR syndrome gene PRRG4 is a functional homologue of the commissureless axon guidance gene
(2017)WAGR syndrome is characterized by Wilm's tumor, aniridia, genitourinary abnormalities and intellectual disabilities. WAGR is caused by a chromosomal deletion that includes the PAX6, WT1 and PRRG4 genes. PRRG4 is proposed ... -

The wind dancer
(2019)Thus, these caterpillars also engage in behavioral crypsis. When disturbed, the caterpillar sways slowly from side to side on two prominent prolegs, mimicking a leaf wavering in the breeze. If predation shaped the natural ... -

Thermal Benefits From White Variegation of Silybum marianum Leaves
(2019)Leaves of the spiny winter annual Silybum marianum express white patches (variegation) that can cover significant surface areas, the outcome of air spaces formed between the epidermis and the green chlorenchyma. We asked: ... -

Trait-mediated trophic cascade creates enemy-free space for nesting hummingbirds
(2015)The indirect effects of predators on nonadjacent trophic levels, mediated through traits of intervening species, are collectively known as trait-mediated trophic cascades. Although birds are important predators in terrestrial ... -

Transcriptome profiling of aging Drosophila photoreceptors reveals gene expression trends that correlate with visual senescence
(2017)Aging is associated with functional decline of neurons and increased incidence of both neurodegenerative and ocular disease. Photoreceptor neurons in Drosophila melanogaster provide a powerful model for studying the molecular ... -

Transcriptomic profiles of Clostridium ljungdahlii during lithotrophic growth with syngas or H-2 and CO2 compared to organotrophic growth with fructose
(2017)Clostridium ljungdahlii derives energy by lithotrophic and organotrophic acetogenesis. C. ljungdahlii was grown organotrophically with fructose and also lithotrophically, either with syngas - a gas mixture containing ... -

Using 3D printed eggs to examine the egg-rejection behaviour of wild birds
(5/26/2015)The coevolutionary relationships between brood parasites and their hosts are often studied by examining the egg rejection behaviour of host species using artificial eggs. However, the traditional methods for producing ... -
