Abstract

Forests that regrow naturally on abandoned fields are important for restoring biodiversity and ecosystem services, but can they also preserve the distinct regional tree floras? Using the floristic composition of 1215 early successional forests (≤20 years) in 75 human-modified landscapes across the Neotropic realm, we identified 14 distinct floristic groups, with a between-group dissimilarity of 0.97. Floristic groups were associated with location, bioregions, soil pH, temperature seasonality, and water availability. Hence, there is large continental-scale variation in the species composition of early successional forests, which is mainly associated with biogeographic and environmental factors but not with human disturbance indicators. This floristic distinctiveness is partially driven by regionally restricted species belonging to widespread genera. Early secondary forests contribute therefore to restoring and conserving the distinctiveness of bioregions across the Neotropical realm, and forest restoration initiatives should use local species to assure that these distinct floras are maintained.

Abstract

Old-growth tropical forests harbor an immense diversity of tree species but are rapidly being cleared, while secondary forests that regrow on abandoned agricultural lands increase in extent. We assess how tree species richness and composition recover during secondary succession across gradients in environmental conditions and anthropogenic disturbance in an unprecedented multisite analysis for the Neotropics. Secondary forests recover remarkably fast in species richness but slowly in species composition. Secondary forests take a median time of five decades to recover the species richness of old-growth forest (80% recovery after 20 years) based on rarefaction analysis. Full recovery of species composition takes centuries (only 34% recovery after 20 years). A dual strategy that maintains both old-growth forests and species-rich secondary forests is therefore crucial for biodiversity conservation in human-modified tropical landscapes.

Abstract

The nutrient demands of regrowing tropical forests are partly satisfied by nitrogen-fixing legume trees, but our understanding of the abundance of those species is biased towards wet tropical regions. Here we show how the abundance of Leguminosae is affected by both recovery from disturbance and large-scale rainfall gradients through a synthesis of forest inventory plots from a network of 42 Neotropical forest chronosequences. During the first three decades of natural forest regeneration, legume basal area is twice as high in dry compared with wet secondary forests. The tremendous ecological success of legumes in recently disturbed, water-limited forests is likely to be related to both their reduced leaflet size and ability to fix N2, which together enhance legume drought tolerance and water-use efficiency. Earth system models should incorporate these large-scale successional and climatic patterns of legume dominance to provide more accurate estimates of the maximum potential for natural nitrogen fixation across tropical forests.

Abstract

Aim: We test the hypothesis that wind dispersal is more common among emergent tree species given that being tall increases the likelihood of effective seed dispersal. Location: Americas, Africa and the Asia-Pacific. Time period: 1970–2020. Major taxa studied: Gymnosperms and Angiosperms. Methods: We used a dataset consisting of tree inventories from 2821 plots across three biogeographic regions (Americas, Africa and Asia-Pacific), including dry and wet forests, to determine the maximum height and dispersal strategy of 5314 tree species. A web search was used to determine whether species were wind-dispersed. We compared differences in tree species maximum height between biogeographic regions and examined the relationship between species maximum height and wind dispersal using logistic regression. We also tested whether emergent tree species, that is species with at least one individual taller than the 95% height percentile in one or more plots, were disproportionally wind dispersed in dry and wet forests within each biogeographic region. Results: Our dataset provides maximum height values for 5314 tree species, of which more than half (2914) had no record of this trait in existing global databases. We found that, on average, tree species in the Americas have lower maximum heights compared to those in Africa and the Asia Pacific. The probability of wind dispersal increased significantly with tree species maximum height and was significantly higher among emergent than non-emergent tree species in both dry and wet forests in all three biogeographic regions. Main conclusion: Wind dispersal is more prevalent in tall, emergent tree species than in non-emergent species and may thus be an important factor in the evolution of tree species maximum height. By providing the most comprehensive dataset so far of tree species maximum height and wind dispersal strategies, this study paves the way for advancing our understanding of the eco-evolutionary drivers of tree size.

Abstract

Forests that regrow naturally on abandoned fields are important for restoring biodiversity and ecosystem services, but can they also preserve the distinct regional tree floras? Using the floristic composition of 1215 early successional forests (≤20 years) in 75 human-modified landscapes across the Neotropic realm, we identified 14 distinct floristic groups, with a between-group dissimilarity of 0.97. Floristic groups were associated with location, bioregions, soil pH, temperature seasonality, and water availability. Hence, there is large continental-scale variation in the species composition of early successional forests, which is mainly associated with biogeographic and environmental factors but not with human disturbance indicators. This floristic distinctiveness is partially driven by regionally restricted species belonging to widespread genera. Early secondary forests contribute therefore to restoring and conserving the distinctiveness of bioregions across the Neotropical realm, and forest restoration initiatives should use local species to assure that these distinct floras are maintained.

Abstract

Tropical forests disappear rapidly because of deforestation, yet they have the potential to regrow naturally on abandoned lands. We analyze how 12 forest attributes recover during secondary succession and how their recovery is interrelated using 77 sites across the tropics. Tropical forests are highly resilient to low-intensity land use; after 20 years, forest attributes attain 78% (33 to 100%) of their old-growth values. Recovery to 90% of old-growth values is fastest for soil (<1 decade) and plant functioning (<2.5 decades), intermediate for structure and species diversity (2.5 to 6 decades), and slowest for biomass and species composition (>12 decades). Network analysis shows three independent clusters of attribute recovery, related to structure, species diversity, and species composition. Secondary forests should be embraced as a low-cost, natural solution for ecosystem restoration, climate change mitigation, and biodiversity conservation.

Abstract

Laelia halbingeriana Salazar & Soto Arenas is a wild epiphytic orchid endemic to Oaxaca, Mexico, that is collected with no plans for its management or conservation. The objective of this study was to propagate and evaluate the in vitro development of this species in the culture media with a variety of mineral salts and growth regulators. Groups of three plants, 1.2 to 1.4 cm tall, were established in receptacles with culture medium containing 30 g L-1 sucrose, 1 mg L-1 thiamine, 100 mg L-1 inositol and 0.5 mg L-1 benzyl aminopurine (BAP). Proportions of Murashige and Skoog (1962) or Knudson (1946) mineral salts were varied (100, 66 and 33%). The growth regulators indoleacetic acid (IAA) and kinetin (Kin) were used at various concentrations (0.5 + 0.5 mg L-1, 1 + 1 mg L-1 and 2 + 2 mg L-1). pH was adjusted to 5.8, and 5.5 g L-1 agar was added. After 120 days of incubation, the plants that were cultivated in 66% and 100% Knudson media were 2.1 cm tall and had 4.8 roots, while the plants in 100% Murashige and Skoog media were 1.5 cm tall and had 2.5 roots. For 120 days, the plants had a logarithmic trend in vertical growth (R2≥0.96). Several plant characteristics were evaluated simultaneously using a cluster analysis, which found that the best culture medium for Laelia halbingeriana development contains 100% Knudson mineral salts, 0.5 mg L-1 BAP, 0.5 mg L-1 IAA, and 0.5 mg L-1 KIN.

Abstract

Dieulafoy’s lesion represents approximately 2% of all causes of upper gastrointestinal bleeding. In most cases, this malformation is located in the stomach, mainly in the lesser curvature. We present the case of a young adult with hematemesis and signs of hypovolaemia. During the esophagogastroduodenoscopy, a clot adhering to the gastric body was seen at the level of the greater curvature, suggestive of Dieulafoy’s lesion. Initially, medical management was performed without significant improvement, so an exploratory laparotomy was performed with resection of the vascular malformation, the histopathological report confirmed the diagnosis. Despite being an uncommon cause of upper gastrointestinal bleeding, the Dieulafoy lesion must be considered among the differential diagnoses, especially if the hemorrhage persists even with medical management. MÉD.UIS.2019;32(1):27-31., La lesión de Dieulafoy representa aproximadamente el 2% de todos los casos de hemorragia gastrointestinal superior. En la mayoría de casos esta anomalía se ubica en el estómago, principalmente en la curvatura menor. Se presenta el caso de un adulto joven con hematemesis y signos de hipovolemia. Durante la esofagogastroduodenoscopia se evidenció un coágulo adherido en el cuerpo gástrico a nivel de la curvatura mayor, sugestivo de lesión de Dieulafoy. Inicialmente se realizó manejo médico sin mejoría significativa, por lo que se realizó laparotomía exploratoria con resección de la malformación vascular, finalmente con el informe histopatológico se confirmó el diagnóstico. A pesar de ser una causa infrecuente de hemorragia gastrointestinal superior, la lesión de Dieulafoy debe considerarse entre los diagnósticos diferenciales, especialmente si la hemorragia persiste aún con manejo médico.

Abstract

Old-growth tropical forests harbor an immense diversity of tree species but are rapidly being cleared, while secondary forests that regrow on abandoned agricultural lands increase in extent. We assess how tree species richness and composition recover during secondary succession across gradients in environmental conditions and anthropogenic disturbance in an unprecedented multisite analysis for the Neotropics. Secondary forests recover remarkably fast in species richness but slowly in species composition. Secondary forests take a median time of five decades to recover the species richness of old-growth forest (80% recovery after 20 years) based on rarefaction analysis. Full recovery of species composition takes centuries (only 34% recovery after 20 years). A dual strategy that maintains both old-growth forests and species-rich secondary forests is therefore crucial for biodiversity conservation in human-modified tropical landscapes.
