Despite long-standing interest in elevational-diversity gradients, little is known about the processes that cause changes compositional variation of communities (β-diversity) across elevations. Recent studies have suggested β-diversity gradients are driven by species pools, rather than strength local community assembly mechanisms such as dispersal limitation, environmental filtering, or biotic interactions. However, tests this hypothesis been limited to very small spatial scales limit...
Abstract Questions Does addition of an arbuscular mycorrhizal fungi ( AMF ) inoculum increase the short‐term restoration success nutrient‐poor grassland NPG after topsoil removal? distance to intact remnant IRG patches affect success, and does effect depend on s? Location Meerdaal forest, Oud‐Heverlee, Belgium. Methods In a topsoil‐removed site 8.5 ha, where 24 (ca. 10% area) were kept, 48 plots (1 m 2 established at three distances (5, 10 20 m) from edge patches. Half each class inoculated...
Understanding patterns and mechanisms of variation in the compositional structure communities across spatial scales is one fundamental challenges ecology biogeography. In this study, we evaluated effects extent (i.e. size study region) on: 1) whether community composition can be better explained by environmental niche‐based) or (e.g. dispersal‐based) processes ; 2) how climate soils contribute to influence environment on plant composition. We surveyed a network 398 forest plots spanning...
A fundamental objective of evolutionary biology is to understand the origin independently evolving species. Phylogenetic studies species radiations rarely are able document ongoing speciation; instead, modes speciation, entailing geographic separation and/or ecological differentiation, posited retrospectively. The Oreinotinus clade Viburnum has radiated recently from north south through cloud forests Mexico and Central America Andes. Our analyses support a hypothesis incipient speciation in...
The goal of this study was a quantitative assessment two‐dimensional commonness in the lowland, dry, and montane tropical forests Madidi region (Bolivia). This spans large elevational environmental gradient, with great diversity differences among sites. We aimed to correlate patterns at different scales elevation size species pool. also developed 1) measure ecological 2) criterion separate common from uncommon species; both based on h index academic productivity. With approach, we calculated...
Abstract Aim Oligarchic patterns can vary from weak (i.e. little difference between rare and common species) to strong a set of dominant species is immediately evident). Our aim was understand the relationships strength oligarchic patterns, diversities (alpha, beta gamma), five potential causes (elevational variability, soil heterogeneity, elevation, conditions geographical extent). Location The Amazon–Andes transition in Madidi region (Bolivia). Methods We established 398 plots 0.1 ha each,...
Abstract Aim Rarity, which is believed to influence extinction risk, can be defined in terms of local abundance, geographical range size and habitat breadth. Phylogenetic patterns these attributes provide insight into the extent rarity risk are conserved during evolution potential for species‐level heritability. We evaluated phylogenetic signal (i.e., related species resembling each other more than drawn at random) evolutionary conservatism (similarity among exceeding that expected from a...
Specific leaf area (SLA; fresh-leaf area/dry mass) describes the amount of for light capture per unit biomass invested. The standard protocol is simple; however, it requires recently collected sun-exposed leaves to determine area, limiting where and which samples can be studied. A predict SLA fresh from herbarium-dried was developed in a dry forest Bolivia. Leaf measured both dried on same generate two general mixed-effects models, varying their inclusion position crown developed. As test...
Abstract Aim We examined tree beta diversity in four biogeographical regions with contrasting environmental conditions, latitude, and diversity. tested: (a) the influence of species pool on diversity; (b) relative contribution niche‐based dispersal‐based assembly to (c) differences importance these two mechanisms differing productivity richness. Location Lowland montane tropical forests Madidi region (Bolivia), lowland temperate Ozarks (USA), Cantabrian Mountains (Spain). Methods surveyed...
Abstract Questions We investigated how the establishment of sown target species for ecological restoration is affected by early introduction either dominant or subordinate during assembly a restored topsoil‐stripped, nutrient‐poor grassland. Do exert different priority effects on wanted unwanted pioneer species? If are detected, these exerted via niche preemption modification mechanisms? Are resulting patterns related to differences in functional trait composition? Location Meerdaal forest,...
During a revision of Serpocaulon from Colombia, new hybrid was found between S. adnatum and levigatum near to Manizales city, which is described illustrated herein. Qualitative quantitative spore macro-morphological characters were evaluated using principal component analyses distinguish the taxon. Our results suggest that perispore with leasura, lamina width, rhizome diameter, blade dissection number pinnae are important × manizalense. This first record simple pinnate-leaved species in...
<title>Abstract</title> Coffee-related agricultural intensification affects bird species abundance, richness, and composition through habitat loss degradation. Production of specialty coffee is expected to be more sustainable environmentally friendly than conventional coffee. Nevertheless, not all grown sustainably. To evaluate environmental sustainability, we evaluated the assemblages in six coffee-producing communities Bolivia’s pre-montane subtropical humid forest region. do this,...
Una nueva especie del género Styloceras Kunth ex A. Juss. (Buxaceae), fue encontrada en los bosques nublados Parque Nacional Madidi y la Reserva Biosfera Tierra Comunitaria de Origen Pilón Lajas Andes Bolivianos. Se describe e ilustra a S. connatum Torrez & P. Jørg., taxón que presenta similitudes morfológicas con penninervium H. Gentry Aymard, pero se distingue está por consistencia las hojas, número anteras, color flores características fruto. proporciona una clave para identificación...
