Seasonally dry tropical forests are distributed across Latin America and the Caribbean highly threatened, with less than 10% of their original extent remaining in many countries. Using 835 inventories covering 4660 species woody plants, we show marked floristic turnover among regions, which may be higher other neotropical biomes, such as savanna. Such high indicates that numerous conservation areas countries will needed to protect full diversity forests. Our results provide a scientific...
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 their recovery is interrelated using 77 sites across tropics. are highly resilient low-intensity land use; after 20 years, attain 78% (33 100%) old-growth values. Recovery 90% values fastest for soil (<1 decade) plant functioning (<2.5 decades), intermediate structure species diversity (2.5...
The aim of this study was to provide new insights into how intraspecific variability in the response key functional traits drought dictates interplay between gas-exchange parameters and hydraulic architecture European beech (Fagus sylvatica L.). Considering relationships leaf traits, we tested whether local adaptation water stress occurs species. To address these objectives, conducted a glasshouse experiment which 2-year-old saplings from six populations were subjected different watering...
Tropical dry forests (TDFs) have been defined as a single biome occurring mostly in the lowlands where there is marked period of drought during year. In Neotropics, occur across contrasting biogeographical regions that contain high beta diversity and endemism, but also strong anthropogenic pressures threaten their biodiversity ecological integrity. Colombia, TDFs six with soils, climate, pressures, therefore being ideal for studying how these variables relate to forest species composition,...
Mexico has 18 species of Triatomine bugs (Hemiptera: Reduviidae) reported to be vectors Trypanosoma cruzi. Chagas Disease is widespread in Mexico, with up 3.5% seropositivity human transfusion blood. The State Oaxaca the longest history endemic Disease, based on acute and chronic case reports, entomological surveys country.

Abstract. Chagas disease caused by infection with Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae) is widespread in Mexico, transmitted various triatomine bugs (Hemiptera: Reduviidae). The only domestic vector Cuernavaca (population 650 000) Triatoma pallidipennis (Ståhl) T. seroprevalence ranging from 1% to 9% the resident human population. We surveyed possible risk factors for infestation at (altitude 1200–2200 m) on south‐western slopes of Sierra Madre Occidental. This metropolitan...
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 floristic composition of 1215 early successional forests (≤20 years) in 75 human-modified landscapes across Neotropic realm, we identified 14 groups, with a between-group dissimilarity 0.97. Floristic groups were associated location, bioregions, soil pH, temperature seasonality, water availability. Hence, there...
Conservation areas in tropical forests protect the most diverse and threatened ecosystems on planet. In Amazon, ungulates are important determinants of forest structure plant diversity, as well being a resource for rural communities. Using occupancy-based methods, we estimated occurrence white-lipped peccary Tayassu pecari, collared Pecari tajacu, lowland tapir Tapirus terrestris red brocket deer Mazama americana around protected reserve Tambopata, Peru, to evaluate how different management...
Abstract Tropical dry forests ( TDF ) are known to be resource‐limited due a marked seasonality in precipitation. However, also shaped by factors such as solar radiation, wind speed, soil fertility, and land‐cover transformation. Together, these may determine different gradients of environmental harshness that likely drive changes plant community attributes. Here, we evaluated the effects on diversity structure Colombian , based floristic data from 15 1‐ha permanent plots. We analyzed...

Societal Impact Statement Tropical dry forests (TDF) underpin the wellbeing of millions, mostly rural populations; yet have suffered from severe clearing in Colombia, triggering cascading effects such as desertification. By engaging scientists, society, and institutions establishment platforms for monitoring biodiversity ecosystem functioning, crucial knowledge gaps will be bridged, helping to find a path toward sustainable development. Science‐led but socially economically anchored...
Previous studies have shown that environmental conditions and plant attributes determine biomass stocks productivity across multiple tropical forests. However, it is less clear how these factors act at local scales. We evaluated the spatial variation of soil resource availability (soil nutrient water content) functional traits species in a Colombian dry forest, based on spatially explicit sampling an intensive trait characterization 89 three 1-ha permanent plots with similar climate...
ABSTRACT The Caquetá titi monkey ( Plecturocebus caquetensis ) is Critically Endangered (CR) due to habitat destruction associated with extensive livestock ranching and farming. But unfortunately, information on the ecology behavior of species scarce. Here we describe seasonal behavioral patterns home range size P. in a 23-ha forest fragment Colombia. In 2013, collected focal animal data group seven individuals . Overall, monkeys spent 33% their time feeding, 4% locomotion, 42% resting, 21%...

Abstract Scorpion stings cause more morbidity in Mexico than any other country, leading to about 100 deaths annually. In 1999, the State of Morelos reported nine among 30 663 cases scorpion sting. To replace lindane used for control, field trials pyrethroid pesticides were undertaken during 1998–2000 at village Chalcatzingo (population initially with 2760 inhabitants and 530 houses). Pre‐intervention surveys detected scorpions (Scorpiones: Buthidae) two species majority houses: Centruroides...
