Maintenance of photosynthetic capacity in flooded tomato plants with reduced ethylene sensitivity.

Physiol Plant 2020 May 27. Epub 2020 May 27.

Instituto de Botánica del Nordeste (UNNE-CONICET), 2131 Sargento Cabral, CP 3400, Corrientes, Argentina.

Ethylene is considered one of the most important plant hormones orchestrating plant responses to flooding stress. However, ethylene may induce deleterious effects on plants, especially when produced at high rates in response to stress. In this paper, we explored the effect of attenuated ethylene sensitivity in the Never ripe (Nr) mutant on leaf photosynthetic capacity of flooded tomato plants. Read More

Stream fish metacommunity organisation across a Neotropical ecoregion: The role of environment, anthropogenic impact and dispersal-based processes.

PLoS One 2020 26;15(5):e0233733. Epub 2020 May 26.

Laboratório de Biogeografia e Ecologia Aquática (Bioecol), Universidade Estadual de Goiás, Anápolis, Goiás, Brazil.

Understanding how assemblages are structured in space and the factors promoting their distributions is one of the main goals in Ecology, however, studies regarding the distribution of organisms at larger scales remain biased towards terrestrial groups. We attempt to understand if the structure of stream fish metacommunities across a Neotropical ecoregion (Upper Paraná-drainage area of 820,000 km2) are affected by environmental variables, describing natural environmental gradient, anthropogenic impacts and spatial predictors. For this, we obtained 586 sampling points of fish assemblages in the ecoregion and data on environmental and spatial predictors that potentially affect fish assemblages. Read More

Effects of biological traits on capture-induced parturition in a freshwater stingray and perspectives for species management.

J Fish Biol 2020 May 24. Epub 2020 May 24.

UNESP, Universidade Estadual Paulista, Departamento de Biologia e Zootecnia, Laboratório de Estudos em Fisiologia Animal, Rua Monção, 226, Ilha Solteira, SP, Brazil.

Elasmobranchs are particularly vulnerable to overexploitation and population depletion, especially due to their life-history traits, such as low reproductive output and slow growth. Given that capture-induced parturition (abortion or premature birth) is a common consequence of fisheries in elasmobranchs, but still little studied, we investigated how the abortion/premature birth process varies in response to reproductive traits in a freshwater stingray, Potamotrygon amandae. Our results revealed that capture-induced parturition was affected by reproductive traits, such as litter size (one to seven) and gestation stage. Read More

Multichromosomal structure and foreign tracts in the Ombrophytum subterraneum (Balanophoraceae) mitochondrial genome.

Plant Mol Biol 2020 May 22. Epub 2020 May 22.

IBAM, Universidad Nacional de Cuyo, CONICET, Facultad de Ciencias Agrarias, Almirante Brown 500, M5528AHB, Chacras de Coria, Mendoza, Argentina.

Horizontal gene transfer (HGT) is frequent in parasitic plant mitochondria as a result of vascular connections established in host-parasite relationships. Recent studies of the holoparasitic plant Lophophytum mirabile (Balanophoraceae) revealed the unprecedented acquisition of a large amount of mitochondrial sequences from its legume host. We focused on a close relative, the generalist holoparasite Ombrophytum subterraneum, to examine the incidence of HGT events in the mitochondrial genome (mtDNA). Read More

Using a multistate occupancy approach to determine molecular diagnostic accuracy and factors affecting avian haemosporidian infections.

Sci Rep 2020 May 21;10(1):8480. Epub 2020 May 21.

Departamento de Parasitologia, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil.

The use of a sensitive and accurate parasite detection methodology is crucial in studies exploring prevalence of parasites in host populations or communities, and uncertainty in identifying parasite genera and/or lineages may limit the understanding of host-parasite interactions. Here, we used a multistate occupancy approach that accounts for imperfect detection to assess whether sex and breeding season influenced the prevalence of a specific Haemoproteus lineage (TARUF02) in a white-lined tanager population. Likewise, we explored whether the probability of detecting the target parasite in an infected bird using PCR and sequencing analyses may be influenced by season and host sex. Read More

Sexual modulation in a polyploid grass: a reproductive contest between environmentally inducible sexual and genetically dominant apomictic pathways.

Sci Rep 2020 May 20;10(1):8319. Epub 2020 May 20.

Department of Systematics, Biodiversity and Evolution of Plants, Albrecht-von-Haller Institute for Plant Sciences, University of Goettingen, Untere Karspuele 2, 37073, Goettingen, Germany.

In systems alternating between sexual and asexual reproduction, sex increases under unfavorable environmental conditions. In plants producing sexual and asexual (apomictic) seeds, studies on the influence of environmental factors on sex are equivocal. We used Paspalum intermedium to study environmental effects on the expression of sexual and apomictic developments, and on resulting reproductive fitness variables. Read More

Fluorescence emission spectra of target chloroplast metabolites (flavonoids, carotenoids, lipofuscins, pheophytins) as biomarkers of air pollutants and seasonal tropical climate.

Environ Sci Pollut Res Int 2020 Apr 28. Epub 2020 Apr 28.

Centro de Ciências Naturais e Humanas, Universidade Federal do ABC, Rua Arcturus 03, São Bernardo do Campo, 09606-070, Brazil.

Chloroplasts have luminescent metabolites-chlorophyll being the most known one-whose fluorescence emission may be a useful tool to assess the physiological status of the plant. Some antioxidants (flavonoids and carotenoids), and byproducts of membrane rupture (lipofuscins) and chlorophyll degradation (pheophytins), are chloroplasts' fluorescent metabolites directly involved in plant response to environmental stressors and pollutants and may act as a biomarker of stress. Here we hypothesized that climatic variations and air pollutants induce alterations in the emission profile of chloroplasts' fluorescent metabolites in Tillandsia usneoides (Bromeliaceae). Read More

Pectic galactan affects cell wall architecture during secondary cell wall deposition.

Planta 2020 Apr 23;251(5):100. Epub 2020 Apr 23.

Departamento de Botánica y Fisiología Vegetal, Centro Hispano Luso de Investigaciones Agrarias (CIALE), Universidad de Salamanca, 37007, Salamanca, Spain.

Main Conclusion: β-(1,4)-galactan determines the interactions between different matrix polysaccharides and cellulose during the cessation of cell elongation. Despite recent advances regarding the role of pectic β-(1,4)-galactan neutral side chains in primary cell wall remodelling during growth and cell elongation, little is known about the specific function of this polymer in other developmental processes. We have used transgenic Arabidopsis plants overproducing chickpea βI-Gal β-galactosidase under the 35S CaMV promoter (35S::βI-Gal) with reduced galactan levels in the basal non-elongating floral stem internodes to gain insight into the role of β-(1,4)-galactan in cell wall architecture during the cessation of elongation and the beginning of secondary growth.

Flower morphology is correlated with distribution and phylogeny in Bertolonia (Melastomataceae), an herbaceous genus endemic to the Atlantic Forest.

Mol Phylogenet Evol 2020 Apr 20:106844. Epub 2020 Apr 20.

Universidade Federal do Paraná, Departamento de Botânica, Centro Politécnico, Postal Box 19031, Curitiba, Paraná, 81531-970, Brazil.

Several centers of endemism have been proposed for Melastomataceae, particularly in Amazonia and Atlantic Forest. Despite the high degree of human-caused degradation in the last 500 years, the Atlantic Forest still presents some of the largest levels of diversity and endemism across all angiosperms. With several recently described species in the last decade, the knowledge on Bertolonia's distribution and morphological characterization has changed, with most new species found in northern Atlantic Forest and with different flower color patterns than the species from southern Atlantic Forest.

Game meat is a resource widely exploited by rural populations in various parts of the world. In recent decades, the growth in the number of people living near conserved areas has increased the demand for game meat. In this work, based on the Social-ecological Theory of Maximization, we seek to verify the influence of cost-benefit ratio, availability, and subjective preferences (flavor) in the selection of hunted species.

Geomorphological control of habitat distribution in an intermittent shallow saline lake, Gallocanta Lake, NE Spain.

Sci Total Environ 2020 Apr 11;726:138601. Epub 2020 Apr 11.

Estación Experimental de Aula Dei, EEAD-CSIC, Av. Montañana 1005, 50059 Zaragoza, Spain.

The aim of the present study consists on the establishment of any relationship or interaction between geomorphological processes and vegetation/habitat distribution in an area with strong environmental gradients: an active saline lake in NE Spain. The resulting maps of the major geoforms and CORINE habitats within the lacustrine area were overlain to determine any significant relationships, taking into account the elevation derived from Lidar data. Whereas the geoforms resulted to have a roughly concentric distribution, the habitats appeared to be spread across different areas, and flooding frequency seemed not to be a determining factor in their altitudinal distribution.

Elevation and latitude drives structure and tree species composition in Andean forests: Results from a large-scale plot network.

PLoS One 2020 20;15(4):e0231553. Epub 2020 Apr 20.

Department of Geography and the Environment, University of Austin Texas, Texas, United States of America.

Our knowledge about the structure and function of Andean forests at regional scales remains limited. Current initiatives to study forests over continental or global scales still have important geographical gaps, particularly in regions such as the tropical and subtropical Andes. In this study, we assessed patterns of structure and tree species diversity along ~ 4000 km of latitude and ~ 4000 m of elevation range in Andean forests. Read More

Nuclear phylogeography of the temperate tree species Chiranthodendron pentadactylon (Malvaceae): Quaternary relicts in Mesoamerican cloud forests.

BMC Evol Biol 2020 Apr 19;20(1):44. Epub 2020 Apr 19.

Departamento de Botánica y Zoología, Centro Universitario de Ciencias Biológicas y Agropecuarias, Universidad de Guadalajara, Camino Ing. Ramón Padilla Sánchez 2100, Nextipac, 45200, Nextipac, Zapopan, Jalisco, México.

Background: The Mexican hand tree or Canac (Chiranthodendron pentadactylon) is a temperate tree species of cloud and pine-oak forests of southern Mexico and Guatemala. Its characteristic hand-shaped flower is used in folk medicine and has constituted the iconic symbol of the Sociedad Botánica de México since 1940. Here, the evolutionary history of this species was estimated through phylogeographic analyses of nuclear DNA sequences obtained through restriction site associated DNA sequencing and ecological niche modeling.

Linking patterns and processes of tree community assembly across spatial scales in tropical montane forests.

Ecology 2020 Apr 18. Epub 2020 Apr 18.

Departamento de Biología, Geología, Física y Química Inorgánica, Universidad Rey Juan Carlos, Calle Tulipán s/n, Móstoles, Madrid, ES- 28933, Spain.

Many studies have tried to assess the role of both deterministic and stochastic processes in community assembly, yet a lack of consensus exists on which processes are more prevalent and at which spatial scales they operate. To shed light on this issue, we tested two non-mutually exclusive, scale-dependent hypotheses: 1) that competitive exclusion dominates at small spatial scales; and 2) environmental filtering does so at larger ones. To accomplish this, we studied the functional patterns of tropical montane forest communities along two elevational gradients, in Ecuador and Peru, using floristic and functional data from 60 plots of 0.

Is dispersal mode a driver of diversification and geographical distribution in the tropical plant family Melastomataceae?

Mol Phylogenet Evol 2020 Apr 9;148:106815. Epub 2020 Apr 9.

Departamento de Biologia Vegetal, Instituto de Biologia, Universidade Estadual de Campinas, Campinas, SP, Brazil.

Species of plants with different life history strategies may differ in their seed dispersal mechanisms, impacting their distribution and diversification patterns. Shorter or longer distance dispersal is favored by different dispersal modes, facilitating (or constraining) population isolation, which can, in turn, impact speciation and species range sizes. While these associations are intuitive, few studies have explicitly tested these hypotheses for large clades of angiosperms. Read More

Spatial and temporal structure of diversity and demographic dynamics along a successional gradient of tropical forests in southern Brazil.

Ecol Evol 2020 Apr 13;10(7):3164-3177. Epub 2020 Mar 13.

Departamento de Solos e Engenharia Agrícola Laboratório de Biogeoquímica Universidade Federal do Paraná Curitiba Brazil.

Analysis of the structure, diversity, and demographic dynamics of tree assemblages in tropical forests is especially important in order to evaluate local and regional successional trajectories.We conducted a long-term study to investigate how the structure, species richness, and diversity of secondary tropical forests change over time. Trees (DBH ≥ 5 cm) in the Atlantic Forest of southern Brazil were sampled twice during a 10-year period (2007 and 2017) in six stands (1 ha each) that varied in age from their last disturbance (25, 60, 75, 90, and more than 100 years).

Outstanding diversity and microendemism in a clade of rare Atlantic Forest montane frogs.

Mol Phylogenet Evol 2020 Apr 6;149:106813. Epub 2020 Apr 6.

Universidade do Estado de Rio de Janeiro, Instituto de Biologia Roberto Alcântara Gomes, Departamento de Zoologia, Rio de Janeiro, RJ, Brazil; Universidade Federal do Rio de Janeiro, Museu Nacional, Departamento de Vertebrados, Rio de Janeiro, RJ, Brazil.

Distributed across topographically complex landscapes that vary from lowland to high elevation, the Atlantic Forest harbors one of the richest biotas worldwide. Atlantic Forest amphibians are particularly speciose, taxonomic accounts are rising and the group is used as model for biogeographic inference. Past climate-related habitat fragmentation is often invoked to explain diversification, with montane taxa expected to become more widespread during glacial times and restrained at interglacials.
