Decarboxylation mechanisms of C4 photosynthesis in Saccharum spp.: increased PEPCK activity under water-limiting conditions.

BMC Plant Biol 2019 Apr 16;19(1):144. Epub 2019 Apr 16.

Agronomy Graduate Program, Universidade do Oeste Paulista (UNOESTE), Rodovia Raposo Tavares, Km 572, CEP, Presidente Prudente, SP, 19067-175, Brazil.

Background: C4 plants have been classified into three subtypes based on the enzymes used to decarboxylate C4 acids in the bundle sheath cells (NADP-ME, NAD-ME and PEPCK pathways). Evidences indicate that, depending on environmental factors, C4 plants may exhibit a certain degree of flexibility in the use of the decarboxylation mechanisms. In this context, the objective was to extend the knowledge on the degree of flexibility between the pathways of decarboxylation in sugarcane, a NADP-ME species, at different levels of water deficit.

Aquat Toxicol 2019 Mar 25;211:163-172. Epub 2019 Mar 25.

College of Life Sciences, Central China Normal University, Wuhan, 430079, Hubei, PR China. Electronic address:

The mechanisms of cadmium toxicity to cyanobacterial photosynthesis have been extensively studied, but the response mechanisms to combinations of different cadmium concentrations and different light intensities are not yet well understood. The two principal objectives of the present work were to: 1) study the short term (5 h) toxic effects of cadmium on Synechocystis PCC6803 under three different culturing light intensity conditions; and, 2) investigate the effects of light history on Cd toxicity to Synechocystis. The maximal (Ф) and operational (Ф') photosystem II quantum yields, photosystem I quantum yield [Y (I)], cyclic electron flow, relative photochemical quenching (qPrel), relative non-photochemical quenching (qNrel), relative unquenched fluorescence (UQFrel), pigment contents, and cadmium uptake were evaluated when Synechocystis cells were treated with cadmium for 5 h under three different light conditions.

Is Planting Trees Enough? The Effect of Different Types of Reforestation on the Offspring of Trypoxylon (Trypargilum) lactitarse (Hymenoptera: Crabronidae) in the Southern Amazon.

Neotrop Entomol 2019 Apr 9. Epub 2019 Apr 9.

Dept de Ecologia e Botânica, Lab de Ecologia de Comunidades, Univ Federal de Mato Grosso, Cuiabá, Mato Grosso, Brasil.

The deforestation has led to local loss of species and important ecosystem services performed by them, causing ecological and economic losses. It is proposed that the reforestation of such areas aims to reduce those impacts. However, particularly in the tropics, little is known about the real success of different types of reforestation in the recovery of the species, and especially of the population parameters.

Genetic diversity and differentiation in narrow versus widespread taxa of (Cistaceae) in a hotspot: The role of geographic range, habitat, and reproductive traits.

Ecol Evol 2019 Mar 5;9(6):3016-3029. Epub 2019 Mar 5.

Departamento de Biología Vegetal y Ecología Universidad de Sevilla Sevilla Spain.

Unraveling the relationships between ecological, functional traits and genetic diversity of narrow endemic plants provide opportunities for understanding how evolutionary processes operate over local spatial scales and ultimately how diversity is created and maintained. To explore these aspects in Sierra Nevada, the core of the Mediterranean Betic-Rifean hotspot, we have analyzed nuclear DNA microsatellite diversity and a set of biological and environmental factors (physicochemical soil parameters, floral traits, and community composition) in two strictly endemic taxa from dolomite outcrops of Sierra Nevada ( and subsp. ) and two congeneric widespread taxa ( subsp.

Avian host composition, local speciation, and dispersal drive the regional assembly of avian malaria parasites in South American birds.

Mol Ecol 2019 Apr 8. Epub 2019 Apr 8.

Department of Biology, Rhodes College, Memphis, TN, 38112, USA.

Identifying the ecological factors that shape parasite distributions remains a central goal in disease ecology. These factors include dispersal capability, environmental filters, and geographic distance. Using 520 haemosporidian parasite genetic lineages recovered from 7,534 birds sampled across tropical and temperate South America we tested 1) the latitudinal diversity gradient hypothesis and 2) the distance-decay relationship (decreasing proportion of shared species between communities with increasing geographic distance) for this host-parasite system.

Genetic data improve the assessment of the conservation status based only on herbarium records of a Neotropical tree.

Sci Rep 2019 Apr 5;9(1):5693. Epub 2019 Apr 5.

Departamento de Biologia Geral, Universidade Federal de Minas Gerais, CP 486, Belo Horizonte, MG, 31270-901, Brazil.

Although there is a consensus among conservation biologists about the importance of genetic information, the assessment of extinction risk and conservation decision-making generally do not explicitly consider this type of data. Genetic data can be even more important in species where little other information is available. In this study, we investigated a poorly known legume tree, Dimorphandra exaltata, from the Brazilian Atlantic Forest, a hotspot for conservation. Read More

Influence of the Quaternary Glacial Cycles and the Mountains on the Reticulations in the Subsection of the Genus .

Front Plant Sci 2019 21;10:303. Epub 2019 Mar 21.

Departamento de Botánica, Facultad de Ciencias, Universidad de Granada, Granada, Spain.

Late Neogene and Quaternary climatic oscillations have greatly shaped the genetic structure of the Mediterranean Basin flora, with mountain plant species tracking warm interglacials/cold glacials by means of altitudinal shifts instead of broad latitudinal ones. Such dynamics may have enhanced population divergence but also secondary contacts. In this paper, we use a case example of subsection of (comprising three narrowly distributed endemic species, , , and ) to test for reticulate evolution and recurrent hybridizations between nearby populations.

Natural and human-impacted diversity of bryophytes along an elevational gradient on an oceanic island (La Palma, Canarias).

PLoS One 2019 3;14(4):e0213823. Epub 2019 Apr 3.

Departamento de Botánica, Ecología y Fisiología Vegetal, Plant Conservation and Biogeography Group, Universidad de La Laguna, C/Astrofísico Francisco Sánchez, s/n. La Laguna, Islas Canarias, España.

Bryophytes have been proposed as ideal indicators of ecosystem change, because they are important components of forest integrity, and considerable research indicates that some groups are sensitive to the changes associated with specific human disturbances. Bryophyte richness and abundance have been found to vary predictably along elevational gradients, but the role of human impacts on these distribution patterns remains unclear. The aim of this study is to explore the impact of human disturbance on the elevational patterns of bryophyte diversity, along an elevational gradient. Read More

Biotic homogenization within and across eight widely distributed grasslands following invasion by Bromus inermis.

Ecology 2019 Apr 1:e02717. Epub 2019 Apr 1.

Department of Biological Sciences, University of Alberta, Alberta, Canada, T6G 2E9.

Invasive species can alter community structure and function of the communities they invade, as well as lead to biotic homogenization across their invasive range, thus affecting large-scale diversity patterns. The mechanisms by which invasive species can lead to biotic homogenization are poorly understood. We argue that invasive species acting as a strong, deterministic and consistent filters within and across invaded communities are likely to cause biotic homogenization at multiple spatial scales.

Evolution of host plant use and diversification in a species complex of parasitic weevils (Coleoptera: Curculionidae).

PeerJ 2019 20;7:e6625. Epub 2019 Mar 20.

Island Ecology and Evolution Research Group, IPNA-CSIC, La Laguna, Tenerife, Canary Islands, Spain.

Weevils (Coleoptera: Curculionoidea) represent one of the most diverse groups of organisms on Earth; interactions with their host plants have been recognized to play a central role in their remarkable diversity, yet the exact mechanisms and factors still remain poorly understood. Using phylogenetic comparative analyses, here we investigate the evolution of host use and its possible role in diversification processes of and , two closely related groups of weevils that feed and develop inside plant tissues of hosts within the families Scrophulariaceae and Plantaginaceae. We found strong evidence for phylogenetic conservatism of host use at the plant family level, most likely due to substantial differences in the chemical composition of hosts, reducing the probability of shifts between host families.

Laboratório de Ecologia e Evolução de Sistemas Socioecológicos (LEA), Centro de Biociências, Departamento de Botânica, Universidade Federal de Pernambuco, Recife, Pernambuco, Brazil.

Throughout evolutionary history, humans have been exposed to a wide variety of diseases, some of which have serious and even lethal consequences. Memorizing medicinal plants for the treatment of serious diseases likely maximized the chances of survival and reproduction and was instrumental in the evolutionary success of our species. In the present study, we used the idea of adaptive memory to understand whether human memory evolved to recall information about medicinal plants for the treatment of serious diseases. Read More

No borders during the post-glacial assembly of European bryophytes.

Ecol Lett 2019 Mar 22. Epub 2019 Mar 22.

Institute of Botany, University of Liege, Sart Tilman, 4000, Liege, Belgium.

Climatic fluctuations during the Last Glacial Maximum (LGM) exerted a profound influence on biodiversity patterns, but their impact on bryophytes, the second most diverse group of land plants, has been poorly documented. Approximate Bayesian computations based on coalescent simulations showed that the post-glacial assembly of European bryophytes involves a complex history from multiple sources. The contribution of allochthonous migrants was 95-100% of expanding populations in about half of the 15 investigated species, which is consistent with the globally balanced genetic diversities and extremely low divergence observed among biogeographical regions.

Fire and legume germination in a tropical savanna: ecological and historical factors.

Ann Bot 2019 Mar 20. Epub 2019 Mar 20.

Universidade Estadual Paulista (UNESP), Instituto de Biociências, Lab of Vegetation Ecology, Rio Claro, Brazil.

Background And Aims: In many flammable ecosystems, physically dormant seeds show dormancy-break patterns tied to fire, but the link between heat shock and germination in the tropical savannas of Africa and South America remains controversial. Seed heat tolerance is important, preventing seed mortality during fire passage, and is usually predicted by seed traits. This study investigated the role of fire frequency (ecological effects) and seed traits through phylogenetic comparison (historical effects), in determining post-fire germination and seed mortality in legume species of the Cerrado, a tropical savanna-forest mosaic.

Departamento de Ecologia e Recursos Marinhos, Universidade Federal do Estado do Rio de Janeiro (UNIRIO), Av. Pasteur 458, Urca, Rio de Janeiro, RJ, 22290-040, Brazil.

Camorim is a small, eutrophic reservoir in Rio de Janeiro, Brazil, with a phytoplankton community dominated most of the year by the filamentous diatom Aulacoseira spp. and the toxic cyanobacterium Cylindrospermopsis raciborskii. As filamentous species can be a poor food for grazers, we hypothesize that phytoplankton from this reservoir would constrain cladoceran fitness due to nutritional limitation and/or toxicity when animals fed mixtures of cultured green algae and natural seston.

Megaphylogeny resolves global patterns of mushroom evolution.

Nat Ecol Evol 2019 04 18;3(4):668-678. Epub 2019 Mar 18.

Synthetic and Systems Biology Unit, Biological Research Centre, Hungarian Academy of Sciences, Szeged, Hungary.

Mushroom-forming fungi (Agaricomycetes) have the greatest morphological diversity and complexity of any group of fungi. They have radiated into most niches and fulfil diverse roles in the ecosystem, including wood decomposers, pathogens or mycorrhizal mutualists. Despite the importance of mushroom-forming fungi, large-scale patterns of their evolutionary history are poorly known, in part due to the lack of a comprehensive and dated molecular phylogeny.

Effects of increasing aridity and chronic anthropogenic disturbance on seed dispersal by ants in Brazilian Caatinga.

J Anim Ecol 2019 Mar 18. Epub 2019 Mar 18.

Departamento de Botânica, Universidade Federal de Pernambuco, Recife, PE, Brazil.

Anthropogenic disturbance and climate change are the main drivers of biodiversity loss and ecological services around the globe. There is concern that climate change will exacerbate the impacts of disturbance and thereby promote biotic homogenization, but its consequences for ecological services are unknown. We investigated the individual and interactive effects of increasing chronic anthropogenic disturbance (CAD) and aridity on seed dispersal services provided by ants in Caatinga vegetation of north-eastern Brazil.

Departamento de Biodiversidad, Real Jardín Botánico, CSIC. Pza. de Murillo, 2, 28014, Madrid, Spain.

Premise Of The Study: Long-distance dispersal (LDD) syndromes, especially endozoochory, facilitate plant colonization of new territories that trigger diversification. However, few studies have analyzed how epizoochorous fruits influence both range distribution and diversification rates. We examined the evolutionary history of a hyperdiverse clade of Boraginaceae (subfamily Cynoglossoideae, eight tribes, ~60 genera, ~1100 species) and the evolution of fruit traits. Read More

Brazilian-adapted soybean Bradyrhizobium strains uncover IS elements with potential impact on biological nitrogen fixation.

FEMS Microbiol Lett 2019 Mar 12. Epub 2019 Mar 12.

GaTE Lab; Departamento de Botânica - Instituto de Biociências, Universidade de São Paulo, 277 Matão Street, 05508-090, São Paulo, SP, Brazil.

Bradyrhizobium diazoefficiens CPAC 7 and Bradyrhizobium japonicum CPAC 15 are broadly used in commercial inoculants in Brazil, contributing to most of the nitrogen required by the soybean crop. These strains differ in their symbiotic properties: CPAC 7 is more efficient in fixing nitrogen, whereas CPAC 15 is more competitive. Comparative genomics revealed many transposases close to genes associated with symbiosis in the symbiotic island of these strains. Read More

Instituto de Botánica Darwinion (CONICET-ANCEFN), Labardén 200, C.C. 22, B1642HYD, San Isidro, Provincia de Buenos Aires, Argentina.

Congruence among different sources of data is highly desirable in phylogenetic analyses. However, plastid and nuclear DNA may record different evolutionary processes such that incongruence among results from these sources can help unravel complex evolutionary histories. That is the case of Nassauvia subgenus Strongyloma (Asteraceae), a taxon with five putative species distributed in the southern Andes and Patagonian steppe. Read More

Old-growth tropical forests harbor an immense diversity of tree species but are rapidly being cleared, while secondary forests that regrow on abandoned agricultural lands increase in extent. We assess how tree species richness and composition recover during secondary succession across gradients in environmental conditions and anthropogenic disturbance in an unprecedented multisite analysis for the Neotropics. Secondary forests recover remarkably fast in species richness but slowly in species composition. Read More

Body mass as a supertrait linked to abundance and behavioral dominance in hummingbirds: A phylogenetic approach.

Ecol Evol 2019 Feb 7;9(4):1623-1637. Epub 2019 Feb 7.

Instituto de Investigaciones en Ecosistemas y Sustentabilidad Universidad Nacional Autónoma de México Morelia Mexico.

Body mass has been considered one of the most critical organismal traits, and its role in many ecological processes has been widely studied. In hummingbirds, body mass has been linked to ecological features such as foraging performance, metabolic rates, and cost of flying, among others. We used an evolutionary approach to test whether body mass is a good predictor of two of the main ecological features of hummingbirds: their abundances and behavioral dominance. Read More

Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological data are not always available for many species at the local or regional scale, we are limited in our understanding of intra- and interspecies spatial morphological variation.
