Evaluating the structure of commensalistic epiphyte-phorophyte networks: a comparative perspective of biotic interactions.

AoB Plants 2019 Apr 7;11(2):plz011. Epub 2019 Mar 7.

Biodiversity and Conservation Area, School of Experimental Sciences (ESCET), Rey Juan Carlos University (URJC), Madrid, Spain.

Epiphytic vascular plants comprise an essential part of the tropical flora and are a key component for ecosystem functioning. Some recent studies have used a network approach to investigate the interaction of epiphytes with host phorophytes at the community level. However, knowledge on commensalistic epiphyte-phorophyte network structure still lags behind with regard to other biotic interaction networks. Read More

Patterns of DNA variation reveal complex evolutionary history of relict and endangered peat bog pine ().

AoB Plants 2019 Apr 14;11(2):plz015. Epub 2019 Mar 14.

Institute of Environmental Biology, Adam Mickiewicz University, Poznań, Poland.

Estimates of genetic differentiation at intra- and interspecific level are often hindered by the lack of suitable molecular markers. Low phylogeographic resolution limits development of appropriate conservation strategies especially in case of endangered forest tree species with small and disjunct distribution. In this study, we assessed fine-scale genetic structure of relict and endangered peat bog pine () and two other closely related European pine species ( and ) using a set of 15 newly developed maternally inherited and seed-mediated mitochondrial DNA (DNA) markers and two previously known polymorphic DNA regions (, ).

Ancestral remnants or peripheral segregates? Phylogenetic relationships of two narrowly endemic species (Orobanchaceae) from the eastern European Alps.

AoB Plants 2019 Apr 19;11(2):plz007. Epub 2019 Feb 19.

Department of Botany and Biodiversity Research, University of Vienna, Vienna, Austria.

Endemism in mountain ranges is considered to be the result of a number of factors, including restriction to refugia during Pleistocene climate fluctuations. However, isolation in glacial refugia cannot explain the origin of narrowly endemic taxa restricted to formerly heavily glaciated areas. Here, we investigate the phylogeny of two narrowly endemic species, and (Orobanchaceae), found exclusively in formerly heavily glaciated areas of the eastern European Alps. Read More

Employing plant functional groups to advance seed dispersal ecology and conservation.

AoB Plants 2019 Apr 7;11(2):plz006. Epub 2019 Feb 7.

Department of Mathematics, Lafayette College, Easton, PA, USA.

Seed dispersal enables plants to reach hospitable germination sites and escape natural enemies. Understanding when and how much seed dispersal matters to plant fitness is critical for understanding plant population and community dynamics. At the same time, the complexity of factors that determine if a seed will be successfully dispersed and subsequently develop into a reproductive plant is daunting. Read More

Herbivore-specific induction of indirect and direct defensive responses in leaves and roots.

AoB Plants 2019 Feb 1;11(1):plz003. Epub 2019 Feb 1.

School of Life Sciences, Henan University, Kaifeng, Henan, China.

Herbivory can induce both general and specific responses in plants that modify direct and indirect defence against subsequent herbivory. The type of induction (local versus systemic induction, single versus multiple defence induction) likely depends both on herbivore identity and relationships among different responses. We examined the effects of two above-ground chewing herbivores (caterpillar, weevil) and one sucking herbivore (aphid) on indirect defence responses in leaves and direct defence responses in both leaves and roots of tallow tree, We also included foliar applications of methyl jasmonate (MeJA) and salicylic acid (SA).

Completing the hybridization triangle: the inheritance of genetic incompatibilities during homoploid hybrid speciation in ragworts ().

AoB Plants 2019 Feb 6;11(1):ply078. Epub 2019 Jan 6.

School of Biology, University of St Andrews, St Andrews, Fife, UK.

A new homoploid hybrid lineage needs to establish a degree of reproductive isolation from its parent species if it is to persist as an independent entity, but the role hybridization plays in this process is known in only a handful of cases. The homoploid hybrid ragwort species, (Oxford ragwort), originated following the introduction of hybrid plants to the UK approximately 320 years ago. The source of the hybrid plants was from a naturally occurring hybrid zone between and on Mount Etna, Sicily. Read More

A member of the CONSTANS-Like protein family is a putative regulator of reactive oxygen species homeostasis and spaceflight physiological adaptation.

AoB Plants 2019 Feb 15;11(1):ply075. Epub 2018 Dec 15.

Plant Molecular and Cellular Biology, University of Florida, Gainesville, FL, USA.

A feature of the physiological adaptation to spaceflight in () is the induction of reactive oxygen species (ROS)-associated gene expression. The patterns of ROS-associated gene expression vary among ecotypes, and the role of ROS signalling in spaceflight acclimation is unknown. What could differences in ROS gene regulation between ecotypes on orbit reveal about physiological adaptation to novel environments? Analyses of ecotype-dependent responses to spaceflight resulted in the elucidation of a previously uncharacterized gene () as being ROS-associated. Read More

Low-intensity logging and hunting have long-term effects on seed dispersal but not fecundity in Afrotropical forests.

AoB Plants 2019 Feb 13;11(1):ply074. Epub 2018 Dec 13.

University Program in Ecology, Duke University, Durham, USA.

Hunting and logging, ubiquitous human disturbances in tropical forests, have the potential to alter the ecological processes that govern population recruitment and community composition. Hunting-induced declines in populations of seed-dispersing animals are expected to reduce dispersal of the tree species that rely on them, resulting in potentially greater distance- and density-dependent mortality. At the same time, selective logging may alter competitive interactions among tree species, releasing remaining trees from light, nutrient or space limitations. Read More

Department of Biology, Southeast Missouri State University, Cape Girardeau, USA.

Plant breeding systems can vary widely among populations, yet few studies have investigated abiotic factors contributing to variation across a broad geographic range. Here we investigate variation in reproductive traits of (Campanulaceae), a species that exhibits dimorphic cleistogamy, a condition in which individual plants have both closed (selfing: cleistogamous: CL) and open (selfing or outcrossing: chasmogamous: CH) flowers. Chasmogamous production is theorized to be more costly because CH flowers have a larger exposed surface area and thus are more likely to lose more water than CL flowers. Read More

We estimated pollinator-mediated selection through female function in L-morph (long-style and short-anther phenotype) and S-morph (short-style and long-anther phenotype) flowers among four populations with different pollinator assemblages. Variation in pollinator assemblage strongly contributed to differences in reproductive success among populations and between morphs of the primrose species. Read More

Hybridization is a frequent process that leads to relevant evolutionary consequences, but there is a lack of studies regarding the relationships of the variability of the response of parental plant species to environmental gradients and the responses of their hybrids at a phenotypic level. We designed an experiment in which we exposed two reciprocal cordgrass hybrids, × and × , and their parental species to four salinity concentrations for 30 days. The main objectives were to compare the performance of the hybrids with that of their parents, to distinguish the phenotypic inheritance operating in the hybrids and to analyse the relationships between the variability in the responses of the parents and the responses of their hybrids to salinity.

Such knowledge will help understand the response of plants to rapid environmental shifts, such as the ones imposed by global climate change. To that end, we undertook a resurrection approach in Spanish populations of the annual plant that were sampled twice over a decade. Read More

Effects of growth under different light spectra on the subsequent high light tolerance in rose plants.

AoB Plants 2018 Oct 12;10(5):ply052. Epub 2018 Sep 12.

Institute of Environment and Sustainable Development in Agriculture, Chinese Academy of Agricultural Science, Beijing, China.

Photosynthesis is defined as a light-dependent process; however, it is negatively influenced by high light (HL) intensities. To investigate whether the memory of growth under monochromatic or combinational lights can influence plant responses to HL, rose plants were grown under different light spectra [including red (R), blue (B), 70:30 % red:blue (RB) and white (W)] and were exposed to HL (1500 μmol m s) for 12 h. Polyphasic chlorophyll a fluorescence (OJIP) transients revealed that although monochromatic R- and B-grown plants performed well under control conditions, the functionality of their electron transport system was more sensitive to HL than that of the RB- and W-grown plants.

Effect of seed removal by ants on the host-epiphyte associations in a tropical dry forest of central Mexico.

AoB Plants 2018 Oct 25;10(5):ply056. Epub 2018 Sep 25.

Centro de Investigación en Biodiversidad y Conservación (CIByC), Universidad Autónoma del Estado de Morelos, Av. Universidad, Col. Chamilpa, Cuernavaca, Morelos, México.

Seed depredation is recognized as a determining factor in plant community structure and composition. Ants are primary consumers of seeds influencing abundance of epiphytes on trees. This study was conducted in two subunits of a tropical dry forest established on different soil substrates in San Andrés de la Cal, Tepoztlán, in Morelos, Mexico, and experimentally tested whether seed removal activity is higher in tree species with smaller epiphyte loads compared to those with greater epiphyte loads.

Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, CO, USA.

Species-level responses to environmental change depend on the collective responses of their constituent populations and the degree to which populations are specialized to local conditions. Manipulative experiments in common-garden settings make it possible to test for population variation in species' responses to specific climate variables, including those projected to shift as the climate changes in the future. While this approach is being applied to a variety of plant taxa to evaluate their responses to climate change, these studies are heavily biased towards seed-bearing plant species. Read More

The impact of floral morphology on genetic differentiation in two closely related biennial plant species.

AoB Plants 2018 Oct 7;10(5):ply051. Epub 2018 Sep 7.

Department of Biology, Plant Conservation and Population Biology, KU Leuven, Leuven, Belgium.

The genetic diversity and structure of plant populations are determined by the interaction of three distinct processes: gene flow, genetic drift and natural selection. These processes are to some extent dependent on the mating system of plants, which in turn is largely determined by floral morphology and the level of herkogamy in particular. In this study, we used molecular markers to investigate the impact of floral morphology on genetic differentiation and structure in two closely related species that display large variation in floral morphology across two distinct geographic regions in Europe (mainland Europe and the UK).

Enhanced cell dehydration tolerance and photosystem stability facilitate the occupation of cold alpine habitats by a homoploid hybrid species, .

AoB Plants 2018 Oct 7;10(5):ply053. Epub 2018 Sep 7.

State Key Laboratory of Grassland Agro-Ecosystems, School of Life Sciences, Lanzhou University, Lanzhou, China.

Homoploid hybrid speciation (HHS), characterized by hybrid speciation without a change in chromosome number and facilitated by ecological divergence, is well known in angiosperms but rare in gymnosperms. as one of two demonstrably conifer diploid hybrid species in gymnosperms has been found to occupy colder alpine habitats than its parents. However, studies on whether leaf frost tolerance and hydraulic safety exhibit transgressive segregation and thus play a role in conifer HHS are still lacking. Read More

is a neotropical genus whose identification is based mostly on characters from external morphology, which are sometimes variable or inadequate for species differentiation. We aimed to verify if leaf anatomy of 18 species brings new characters suitable for species identification and if it corroborates the phylogenetic relationship within the genus.

The relative weight of ontogeny, topology and climate in the architectural development of three North American conifers.

AoB Plants 2018 Aug 31;10(4):ply045. Epub 2018 Jul 31.

CIRAD, UMR AMAP, Montpellier, France.

Knowledge of plant architecture allows retrospective study of plant development, hence provides powerful tools, through modelling and simulation, to link this development with environmental constraints, and then predict its response to global change. The present study aims to determine some of the main endogenous and exogenous variables driving the architectural development of three North American conifers. We measured architectural traits retrospectively on the trunk, branches and twigs of whole tree crowns for each species: annual shoot length (ASL), needle length, branching patterns and reproduction organs (male and female).

Phenotypic plasticity in response to temperature fluctuations is genetically variable, and relates to climatic variability of origin, in .

AoB Plants 2018 Aug 16;10(4):ply043. Epub 2018 Jul 16.

Plant Evolutionary Ecology, Institute of Evolution and Ecology, University of Tübingen, Auf der Morgenstelle, Tübingen, Germany.

Under current climate change, increasing mean temperatures are not only causing hotter summers, but temperature variability is increasing as well. Phenotypic plasticity can help plants to overcome negative effects of temperature variability and allow them to rapidly adjust traits to adverse conditions. Moreover, genetic variation in such plasticity could provide potential for adaptive evolution in response to changing climate variability. Read More

Root condensed tannins vary over time, but are unrelated to leaf tannins.

AoB Plants 2018 Aug 23;10(4):ply044. Epub 2018 Jul 23.

Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada.

Although the negative effects of root herbivores on plant fitness are expected to be similar to those of above-ground herbivores, the study of below-ground plant defences is limited compared to the rich literature on above-ground defences. Current theory predicts that concentrations of defensive chemicals above- and below-ground should be correlated, as the evolutionary drivers that shape plant defence are similar across the whole plant. We conducted a field study to measure root condensed tannin concentrations in , and determine how they related to leaf condensed tannin concentrations, tree position within the stand (edge vs. Read More

The potential for phenological mismatch between a perennial herb and its ground-nesting bee pollinator.

AoB Plants 2018 Aug 2;10(4):ply040. Epub 2018 Jul 2.

Department of Biology, Humboldt State University, Arcata, CA, USA.

Climate change may alter the timing of flowering and pollinator activity to differing degrees, resulting in phenological mismatches between mutualistic partners. Assessing the potential for such mismatches requires an understanding of the environmental factors that cue flowering and pollinator activity. Biological context is key to determining specific impacts of climate change, and therefore it is important to study mutualisms with pollinators of different nesting biologies. Read More

How are monospecific stands of invasive trees formed? Spatio-temporal evidence from Douglas fir invasions.

AoB Plants 2018 Aug 4;10(4):ply041. Epub 2018 Jul 4.

Laboratorio Ecotono, INIBIOMA, CONICET-Universidad Nacional del Comahue, Quintral, Bariloche, Argentina.

Invasive plant species can produce many impacts on native communities. Impacts can be especially important when the non-natives reach high densities, producing monospecific stands where little grows besides the non-native species. We propose three basic pathways by which monospecific stands of invasive tree species are formed: (i) gradually from the propagule source, (ii) via synchronous establishment and (iii) following several pulses of synchronous establishment.

Fragmentation of natural habitats generally has negative effects on the reproductive success of many plant species; however, little is known about epiphytic plants. We assessed the impact of forest fragmentation on plant-pollinator interactions and female reproductive success in two epiphytic species with contrasting life history strategies (polycarpic and monocarpic) in Chamela, Jalisco, Mexico, over three consecutive years. Hummingbirds were the major pollinators of both species and pollinator visitation rates were similar between habitat conditions. Read More

Damage to plants from natural enemies is a ubiquitous feature of the natural world. Accordingly, plants have evolved a variety of strategies to deal with attack from enemies including the ability to simply tolerate attack. Tolerance often involves some form of compensatory response, such as the regrowth of tissues following damage. Read More
