Conservation planning has historically been restricted to planning within single realms (i.e., marine, terrestrial, or freshwater). Recently progress has been made in approaches for cross-realm planning which may enhance the ability to effectively manage processes that sustain biodiversity and ecosystem functions (e.g., connectivity) and thus minimize threats more efficiently. Current advances,…
At present, the production of cement contributes approximately 8% to global carbon dioxide (CO2) emissions, whereas a further increase in the future is expected. To reduce these emissions, a prominent measure of the cement industry is to use materials such as coal fly ash (CFA) as a cement substitute, but the availability of qualified ash is limited. The development of “green cements” w…

Methods: One hundred and thirty-three women (aged 23–40 years) who had had early miscarriages and spontaneous conception participated. Oral dydrogester…
Abstract Aim: To determine whether maternal serum placental growth factor (PlGF) estimation in early second trimester (20–22 weeks of gestation) can predict the occurrence of early onset preeclampsia and/or early onset intrauterine growth restriction (IUGR). Material and Methods: A prospective cohort study was conducted on 722 women with singleton pregnancies, screened from the antenatal cl…
Abstract Aim: A tubal ectopic pregnancy (EP) in the first trimester remains a major life-threatening complication for the mother. We aim to determine whether serum reproductive hormones may be clinically useful in the early identification of a tubal EP. Methods: A total of 109 age-matched patients with a serum b-human chorionic gonadotropin (b-hCG) concentration
Aim: To assess the accuracy of blind vaginal swab in diagnosis of preterm labor (PTL) and prediction of subsequent occurrence of preterm birth (PTB). Methods: Eligible women who presented at 24–34 weeks of gestation with threatened PTL had their cervicovaginal secretions sequentially sampled for fetal fibronectin (fFN) using two types of swabbing techniques. The first swab was a blind vagina…

Abstract Aim: This study aimed to compare the hemodynamic profile and efficacy of carbetocin versus intra-umbilical oxytocin in the management of retained placenta following vaginal delivery. Material and Methods: In this randomized clinical study, women with retained placenta for more than 30min were assigned to receive either an i.v. bolus of 100-μg carbetocin (n = 38) or an intra-umbilica…
1. Growth rates of European silver fir (Abies alba Mill.) rapidly increased in the last century. At the same time, ring widths declined at the species southern distribution limits in the Mediterranean. Such diverse growth trends and responses have largely been attributed to regional climate conditions, but this was prior to considering the species’ post-glacial phylogeny. 2. A dendrochr…
1. Despite time-lags and nonlinearity in ecological processes, the majority of our knowledge about ecosystem responses to long-term changes in climate originates from relatively short-term experiments. 2. We utilized the longest ongoing snow removal experiment in the world and an additional set of new plots at the same location in northern Sweden to simultaneously measure the effects of lo…
1. Humans have a long history of changing species’ ranges and habitat distributions, making studies of the ecological processes that may facilitate these changes of key importance, particularly in cases where a primary foundation species is replaced by another, less desirable species. 2. We investigated the impact of nutrients and herbivory on Turbinaria ornata, a secondary foundational …
1. Plants use light as a source of both energy and information. Plant physiological responses to light, and interactions between plants and animals (such as herbivory and pollination), have evolved under a more or less stable regime of 24-h cycles of light and darkness, and, outside of the tropics, seasonal variation in day length. 2. The rapid spread of outdoor electric lighting across t…
1. Understanding how soil microbial communities influence plant interactions with other organisms, and how this varies with characteristics of the interacting organisms, is important for multiple systems. Solanum spp. are a suitable model for trophic interactions in studies of agricultural and natural systems and can also provide useful corollaries in invaded systems. This study examined the…
1. Plant–fungal interactions can have strong effects on plant abundances, both through direct effects on plant performance and indirect effects on competition and facilitation. Most evidence linking fungi to plant abundances derives from direct fungal effects on initial growth, with little evidence linking fungal effects on plant–plant interactions in intact communities to plant abundanc…
1. Trait differences among plants are expected to influence the outcome of competition; competition should be strongest between similar species (or individuals) under limiting similarity, and between dissimilar species within competitive hierarchies. These hypotheses are often used to infer competitive dynamics from trait patterns within communities. However, plant traits are frequently plas…
1. Invasive herbivores can strongly affect ecosystems by reducing or removing native plant species, and early in primary successions they could have enduring consequences for plant community assembly and ecosystem functioning, although this has seldom been explored. Invasive brushtail possums (Trichosurus vulpecula) browse from ground levels to forest canopies in New Zealand, including on p…
1. In forest communities, the Janzen–Connell (J-C) hypothesis proposes that species diversity is maintained by non-competitive distance- and/or density-dependent seedling mortality caused by host-specific natural enemies. However, the effects of pathogen associations from nearby conspecifics versus heterospecifics remain unknown in spatially heterogeneous light environments. 2. Seeds o…
1. Metapopulation dynamics have been used to explain bryophyte dispersal patterns and they predict that population abundances vary with the spatial distribution of habitat and with species traits. However, results from stand and landscape studies are contradictory as both distance-dependent and distance- independent patterns have been found. These studies have typically included only a few …
1. Understanding the mechanisms by which invasive species affect native plants is a central challenge. Invasive plants have been shown to reduce pollinator visitation to natives and increase pollen quantity limitation. However, visitation and conspecific pollen delivery are the only two components of the pollination process; post-pollination interactions on the stigma (heterospecific pollen …
1. An increase in tree mortality rates has been recently detected in forests world-wide. However, few works have focused on the potential consequences of forest dieback for ecosystem functioning. 2. Here we assessed the effect of Quercus suber dieback on carbon, nitrogen and phosphorus cycles in two types of Mediterranean forests (woodlands and closed forests) affected by the aggressive p…
1. Land-use change can modify the functional composition of tree communities, which is an essential determinant of the ecosystem functions. The lack of consensus about the functional responses of tree communities to land-use change is a major uncertainty in the assessments of human impacts on terrestrial ecosystem functions. 2. In this study, we applied a machine-learning method to a larg…
Since the mid-20th century the Balearic Islands have experienced significant changes as a result of their incorporation into the global economy as a mass tourism destination. The expansion of urbanisation has become a main change, given that the archipelago’s urbanised surface has increased fivefold since 1956. The territory of the islands has been organised internally to meet the demands…
Efforts to preserve fragile ecosystems that focus on removing human intervention from the environment risk ignoring the political and social systems underlying environmentally destructive economic activities. In contrast, a biocultural diversity perspective allows for environmental protection to be approached with sensitivity to human needs. This paper explores the case of Karanrang Island,…
As a province composed of hundreds of small islands, Maluku is highly susceptible to decreasing biodiversity of plant resources for agriculture. Pressures from pests and disease infestations, difficulty of seed storage, market demands for specific cultivars, and the introduction of new superior varieties are decreasing crop and plant genetic diversity and will impact the food security in th…
This article outlines the development of Vietnam’s Con Dao archipelago (and Con Son island in particular) as tourism destinations since the formal reunification of Vietnam in 1975. In particular it examines the nature of the area’s two main tourism attractions, Con Son’s prison sites and memorials and the archipelago’s natural environment, and how these have been marketed to and exp…
Human behavior and the environment interact reciprocally. It is necessary to understand social and ecological systems as an integrated co-evolving social–ecological system (SES) to reveal why an environment is in its current condition and how humans have impacted upon and been influenced by the dynamics of natural system. Many societies in coastal and marine SESs rely on marine natural ca…
The island area has well preserved geodiversity and biodiversity due to minimal exposure to humans. UNESCO has maintained things and sites with geological importance as geoheritage. Although a number of natural heritages and national parks exist on ‘geological’ bases, geodiversity concepts are less concerned about biodiversity due to a lack of recognition. Recently, geotourism linked to…
The Ecosystem Approach to Fisheries (EAF) is a holistic one as EAF considers all species as important elements within the eco-system. An EAF requires that community and ecosystem structure should be maintained by harvesting fish communities in proportion to their natural productivity, thereby sustaining the balance of species and sizes in a community. This article draws from research on the…
Yakushima Island, which has been designated a Biosphere Reserve and World Heritage Site, has rich biodiversity and a culture that depends on the local ecosystem. The biodiversity of this island is characterized by a unique biota because the island is located at a biogeographic boundary. The inhabitants revere nature and use natural resources from the sea, lowlands, and mountains. They have …
The Linnaean system has a set of rules governing botanical nomenclature, zoological nomenclature and bacteriological nomenclature for the scientific naming of species. These set the principles, rules and standards with which authors should comply with when naming new species. In Aotearoa/New Zealand (ANZ), the knowledge and taxonomic systems of Maori (the indigenous people) have largely be…
Cultural diversity is highly dependent on the regional environment and natural resources. From an environmental historical perspective, the course of destruction of human civilization resulting from the depletion of ecosystems and resources, we confirm how the sustainable use of resources and appropriate conservation strategies are contributing to regional development. Due to the recent rap…
Gotjawal, a uniquely formed forest vegetation on the lava terrain located at eastern and western parts of Jeju Island, covers 6% of the island’s land surface. The Gotjawal forests play important roles in establishing the biological and cultural diversity while maintaining ecosystem services. Recently, with the recognition of the diverse ecological and cultural values of the Gotjawal fores…
Sri Lanka has vast dry low-lying plains irrigated using traditional micro-(or meso-) watershed management system referred to as the Tank Cascade System (TCS). We discuss the implications of this irrigation system which include the development of lowland paddy (Oryza sativa L.) farming. In addition, the TCS has retarded negative consequences from chronic and recurrent droughts, seasonal flooding…
The ecosystems present a great diversity worldwide and use various functionalities according to ecologic regions. In this new context of variability and climatic changes, these ecosystems undergo notable modifications amplified by domestic uses of which it was subjected to. Indeed the ecosystems render diverse services to humanity from their composition and structure but the tolerable levels ar…
1. Non-random species loss and gain in local communities change the compositional heterogeneity between communities over time, which is traditionally quantified with dissimilarity-based approaches. Yet, dissimilarities summarize the multivariate species data into a univariate index and obscure the species-level patterns of change, which are central to understand the causes and consequences of …
Flowering is a key life-history event whose timing almost certainly affects both male and female fitness, but tests of selection on flowering time through male fitness are few. Such selection may arise from direct effects of flowering time, and indirect effects through covariance between flowering time and the environment experienced during reproduction. To isolate these intrinsically correlate…
1. Vegetation structure is an important determinant of species habitats and diversity. It is often represented by simple metrics, such as canopy cover, height and leaf area index, which do not fully capture three-dimensional variations in density. Terrestrial laser scanning (TLS) is a technology that can better capture vegetation structure, but methods developed to process scans have been biase…
Similar to seemingly maladaptive genes in general, the persistence of inherited cancer-causing mutant alleles in populations remains a challenging question for evolutionary biologists. In addition to traditional explanations such as senescence or antagonistic pleiotropy, here we put forward a new hypothesis to explain the retention of oncogenic mutations. We propose that although natural defens…
1. The analysis ofmorphological diversity frequently relies on the use ofmultivariate methods for characterizing biological shape. However, many of these methods are intolerant of missing data, which can limit the use of rare taxa and hinder the study of broad patterns of ecological diversity and morphological evolution. This study applied a mutli-data set approach to compare variation in missi…
1. Molecular clock calibration is a crucial step for placing phylogenetic trees in the temporal framework required to test evolutionary hypotheses and estimate evolutionary rates. In general, most authors agree that the best approach is to incorporate multiple calibrations to avoid the risk of bias associated with a single dating source. However, the indiscriminate inclusion of as many calibrat…
1. Using scripting languages such as R to perform population genetic analyses can improve the reproducibility of research, but usingRcan be challenging for many researchers due to its steep learning curve. 2. POPGENREPORT is a new R package that simplifies performing population genetics analyses in R, through the use of a new report-generating function. The function POPGENREPORT allows use…
Zooxanthellate corals (i.e. those harbouring Symbiodinium) are the main builders of the world’s shallow-water marine coral reefs. They represent intimate diverse symbioses between coral animals, single-celled photosynthetic dinoflagellates (Symbiodinium spp.), other microscopic eukaryotes, prokaryotes and viruses. Crabs and other crustaceans, worms, sponges, bivalves and hydrozoans, fishe…
Environmental pollution often accompanies the expansion and urbanization of human populations where sewage and wastewaters commonly have an impact on the marine environments. Here, we explored the potential for faecal bacterial pathogens, of anthropic origin, to spread to marine wildlife in coastal areas. The common zoonotic bacterium Campylobacter was isolated from grey seals (Halichoerus …
The persistence of coral reef ecosystems relies on the symbiotic relationship between scleractinian corals and intracellular, photosynthetic dinoflagellates in the genus Symbiodinium. Genetic evidence indicates that these symbionts are biologically diverse and exhibit discrete patterns of environmental and host distribution. This makes the assessment of Symbiodinium diversity critical to un…
Meta-analysis, the statistical synthesis of pertinent literature to develop evidence-based conclusions, is relatively new to the field of molecular ecology, with the first metaanalysis published in the journal Molecular Ecology in 2003 (Slate & Phua 2003). The goal of this article is to formalize the definition of meta-analysis for the authors, editors, reviewers and readers of Molecular Ecolog…
Honey bee hives are filled with stored pollen, honey, plant resins and wax, all antimicrobial to differing degrees. Stored pollen is the nutritionally rich currency used for colony growth and consists of 40–50% simple sugars. Many studies speculate that prior to consumption by bees, stored pollen undergoes long-term nutrient conversion, becoming more nutritious ‘bee bread’ as microbes pre…
Molecular ecology has moved beyond the use of a relatively small number of markers, often noncoding, and it is now possible to use whole-genome measures of gene expression with microarrays and RNAseq (i.e. transcriptomics) to capture molecular response to environmental challenges. While transcriptome studies are shedding light on the mechanistic basis of traits as complex as personality or phys…
Abstract It is known that the microbial community of the rhizosphere is not only influenced by factors such as root exudates, phenology, and nutrient uptake but also by the plant species. However, studies of bacterial communities associated with tropical rainforest tree root surfaces, or rhizoplane, are lacking. Here, we analyzed the bacterial community of root surfaces of four species of nat…
Abstract As ocean temperatures rise, investigations into what the physiological effects will be on the symbiotic microalga Symbiodinium, and how these may play into the cnidarian bleaching response, have highlighted the contribution of reactive oxygen species (ROS). Previous studies have laid this groundwork using a limited number of Symbiodinium phylotypes, and so this study aims to expand …
Abstract Plant growth-promoting rhizobacteria (PGPR) are common components of the rhizosphere, but their role in adaptation of plants to extreme environments is not yet understood. Here, we examined rhizobacteria associated with ancient clones of Larrea tridentata in the Mohave desert, including the 11,700-year-old King Clone, which is oldest known specimen of this species. Analysis of uncul…
