Abstract Under the recently adopted Kunming‐Montreal Global Biodiversity Framework, 196 Parties committed to reporting status of genetic diversity for all species. To facilitate reporting, three indicators were developed, two which focus on processes contributing conservation: maintaining genetically distinct populations and ensuring are large enough maintain diversity. The major advantage these is that they can be estimated with or without DNA‐based data. However, demonstrating their...
Abstract While many plant species are considered threatened under anthropogenic pressure, it remains uncertain how rapidly we losing diversity. To fill this gap, propose a Global Legume Diversity Assessment (GLDA) as the first step of global diversity assessment. Here describe concept GLDA and its feasibility by reviewing relevant approaches data availability. We conclude that Fabaceae is good proxy for overall angiosperm in habitats much available. As indicators states, comparison richness...
Abstract Recent scientific evidence shows that genetic diversity must be maintained, managed, and monitored to protect biodiversity nature's contributions people. Three indicators, two of which do not require DNA‐based assessment, have been proposed for reporting the Convention on Biological Diversity other conservation policy initiatives. These indicators allow an approximation status trends inform policy, using existing demographic geographic information. Application these has initiated...
Abstract Genetic diversity is essential for maintaining healthy populations and ecosystems. Several approaches have recently been developed to evaluate population genetic trends without necessarily collecting new data. Such “genetic indicators” enable rapid, large-scale evaluation across dozens thousands of species. Empirical studies, when available, provide detailed information that important management, such as estimates gene flow, inbreeding, erosion adaptation. In this article, we argue...
Globally, national, subnational, and supranational entities are creating Biodiversity Strategy Action Plans, to develop concrete commitments actions curb biodiversity loss, meet international obligations achieve a society in harmony with nature. In light of policy makers' increasing recognition genetic diversity helping species ecosystems adapt be resilient during environmental change, this article provides an overview how BSAPs can better incorporate conservation within species. We focus on...
The decline of wild bee populations causes the bee-pollinated plant through deterioration pollination services. Since high species richness generally involves functional group diversity, protecting areas will help to maintain services for plants. However, those do not always include habitats with specialized functions that expand range plants being pollinated. To map important native and their functions, we estimated distributions 13 bumble 1 honey in Japan. were from an ensemble six...
We examined whether gender role in the simultaneous hermaphrodite freshwater snail, Physa acuta, is determined by relative body size a manner predicted size-advantage model. observed body-size combinations of pairs laboratory using field-collected populations. Smaller individuals tended to play "male" (sperm donor), and larger snails "female" recipient). Next, we analyzed mating behaviors involved gender-role decision snail three different combinations, "large" "small" snails. were more...
Summary We assessed the effects of population density and spatial arrangement genetically compatible mates on seed set pollen flow a heterostylous, bumblebee‐pollinated perennial, Primula sieboldii E. Morren (Primulaceae), by using an experimental under natural pollination conditions. also examined intermorph differences in dispersal distance frequency self‐ intramorph fertilization. Seed was significantly correlated with number opposite‐morph flowers within 2 m short‐styled genets, 3...
Abstract Protected areas (PAs) spearhead global conservation efforts, but it has been repeatedly demonstrated that narrowly distributed species are more likely to be unrepresented in PAs. This means where local extinctions outside PAs, a positive feedback loop could render PAs largely ineffective decelerating extinctions, even effectively abate threats. Here we empirically test the elements of this using distribution data for 1,572 threatened plants Japan. Narrowly were indeed less overlap...
Abstract We estimated the gene dispersal distance and magnitude of inbreeding depression from fine‐scale genetic structure in endangered heterostylous perennial Primula sieboldii . indirectly neighbourhood size ( Nb ) standard deviation (σ g detected by using 10 microsatellite markers. also fitness reduction mating among neighbouring individuals caused biparental according to structure. found clear (a significantly positive kinship coefficient within 42.3 m), indirect estimates σ were 15.7 m...
Abstract Question Is a high‐resolution remote‐sensing system based on radio‐controlled helicopter (the ‘Falcon‐ PARS system’) an effective tool to obtain images that can be used identify herbaceous species? Location Watarase wetland, Japan. Methods We applied the wetland composed mainly of Phragmites australis and Miscanthus sacchariflorus . The aerial observation was performed in 100 × 200 m area at flying height 30 m. From obtained images, we tried P. M. through visual interpretation....
The direction and magnitude of species distribution shifts tend to differ among functional types (FTs). Quantifying trait variation interactions will improve our understanding the complex mechanisms that govern ecosystem dynamics their responses climate change. Here, we analyzed differences in juvenile adult temperature ranges Japanese tree at mean, colder edge, warmer edge distributions reveal how traits affect between different FT groups (e.g., deciduous evergreen broad-leaved trees),...
Summary Seed reproduction of a plant species is strongly affected by the spatial structures its population through gene flow patterns. We assessed effects arrangement genetically compatible mates on seed set and heterostylous perennial species, Primula sieboldii E. Morren (Primulaceae), using patchy experimental population. was significantly higher in patches containing opposite‐morph genets than without genets. Pollen within explained 76·9% total pollen flow, while 13·5% ascribed to between...
Abstract In an age of deepening biodiversity crisis, plant species biological studies integrating ecological and genetic approaches, especially exhaustive with a model species, are urgently needed for both assessing the present status implementing effective conservation measures, as comprehensive understanding demographic/genetic interactions involved in vicious cycle population extinction is prerequisite any precise prediction regarding conservation. this article, we summarize major...
Although many people have expressed alarm that we are witnessing a mass extinction, few projections been quantified, owing to limited availability of time-series data on threatened organisms, especially plants. To quantify the risk need monitor changes in population size over time for as species possible. Here, present world's first quantitative projection plant loss at national level, with stochastic simulations based results censuses 1618 taxa 3574 map cells ca. 100 km2. More than 500 lay...
Abstract Desalinized seawater is a vital freshwater source for regions with coastal water scarcity. Mapping desalination plants enables spatially detailed resource assessment. Here, which the first of its kind, we investigated potential application species distribution models (SDMs), are widely used in ecology, to predict global spatial plants. Two regression SDMs, generalized linear model and additive model, along two machine learning random forest boosted were trained tested using...
Abstract Elucidating biodiversity patterns and their background processes is critical in science. Dissimilarity, which calculated based on multivariate biological quantities, a major component of biodiversity. As spatial temporal information availability increases, the scope dissimilarity studies has been expanded to cover various levels types spatiotemporal facets (e.g. gene, community ecosystem function), diverse pairwise indices have developed. However, further development concept...

Under the recently adopted Kunming-Montreal Global Biodiversity Framework (GBF), 196 Parties committed report status of genetic both wild domesticated species. For this, three indicators were developed, two which focus on processes contributing conservation: ensuring that populations are large enough maintain (effective population size Ne 500 indicator) maintaining...
