Abstract Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we limited our capacity to understand variation benefits yield, as well anticipate changes service, develop predictions, and inform management actions. Here, present CropPol, a dynamic, open, database It contains measurements...
Chromosome number changes during the evolution of angiosperms are likely to have played a major role in speciation. Their study is utmost importance, especially now, as probabilistic model available chromosome within phylogenetic framework. In present study, likelihood models were fitted largest family flowering plants, Asteraceae. Specifically, supertree this was used reconstruct ancestral and infer genomic events. Our approach inferred that n = 9. Also, according best explained our data,...
Abstract Intensification of agricultural landscapes to fulfil increased global food demands has dramatically impacted biodiversity and ecosystem services. Several pollinator groups, which are vital for the maintenance pollinator‐dependent crops, have been severely affected by this intensification process. Management tools, such as implementation agri‐environmental schemes, widely proposed improve pollinator's communities pollination services, although effectiveness wildflower strips in...
The interest to study genome evolution, in particular size variation and polyploid incidence, has increased recent years. Still, only a few studies have been focused at community level. Of are high mountain species, because of the frequency narrow endemics their higher susceptibility extinction due effects climate change. In present we explored polyploidy incidence entomophilous plant communities two distinct ranges, Sierra Nevada Picos de Europa National Parks. For that, chromosome numbers...
•In heterocarpy, fruits with different morphologies have been associated alternative strategies of dispersal, germination, dormancy, and seedling competitive ability. In heterocarpic species, it is common to find or dispersal syndromes. The advantage nondispersing has frequently attributed their larger size, but recent studies suggested that this could also be mediated by germination time. main objective our study was investigate which factor, fruit type time, most affects plant performance...
Polyploidy has played an important evolutionary role in the genus Festuca (Poaceae), and several ploidy levels (ranging from 2n = 2x 14 to 12x 84) have been detected date. This study aimed estimate genome size level of two subspecies belonging F. yvesii polyploid complex by flow cytometry chromosome counting. The phenotypic variation cytotypes was also explored, based on herbarium material. subsp. lagascae estimated for first time. Nuclear 2C DNA content summilusitana ranged 21.44 31.91 pg,...
Abstract Premise The lateral membranous expansions of fruits, commonly referred to as wings, have long been theorized serve only dispersal functions. Alternatively, because winged fruits typically earlier seed germination than unwinged we hypothesized that wings could increase the contact surface with water, ultimately triggering germination. Methods We investigated this alternative hypothesis by exploring potential role fruit on in heterocarpic species Anacyclus clavatus (Desf.) Pers....
Fragmentation of natural habitats in intensive agricultural landscapes has led to a significant decline the abundance and quality food sources for honeybees other pollinators, resulting bee decline. This study analyses effects temporal spatial variation flower resources on foraging patterns (Apis mellifera iberiensis) an landscape. Waggle dance decoding was used identify main locations honeybees. Monthly flowering species quantification performed assess possible floral resource changes...
