Article
Global change pressures are jeopardizing the functioning and structure of most tropical forests and clouding the future for their biodiversity and provided services. Although the impact of direct destruction through deforestation and fragmentation is currently in the research portfolio, overgrazing, which is more diffuse and generalized but chronic...

Tropical and subtropical dry forests make up the world’s largest terrestrial ecosystem. However, these forests have been used to establish several productive activities, such as growing crops, rearing livestock, and using the forest resources, due to their ease of access and climatic conditions, which has led to this ecosystem becoming highly threa...

Multiple ecosystem functions need to be considered simultaneously to manage and protect the many ecosystem services that are essential to people and their environments. Despite this, cost effective, tangible, relatively simple, and globally‐relevant methodologies to monitor in situ soil multifunctionality, i.e. the provision of multiple ecosystem f...

Pollinators are crucial for ecosystem functionality; however, little is known about the plant species used by some of these, such as stingless bees. In this study, for the first time, pollen resources used by Melipona mimetica Cockerell (Hymenoptera: Apidae: Meliponini) and Scaptotrigona sp. Moure (Hymenoptera: Apidae: Meliponini) were identified t...

Dispersal, physical conditions and biotic interactions contribute to determine the spatial distribution of individuals in plant populations. Much of what we know has been learned from studies that retrospectively posit mechanisms presumed to have generated the observed spatial patterns. Here we present a prospective approach. We start by measuring...

The dry forest of southern Ecuador and northern Perú (called the Tumbesian region) is known for its high diversity, endemism, and healthy conservation state. Nevertheless, the forest is exposed to many threats linked with human activities. To understand the effects of these threats, which have not been appropriately assessed, we pose two questions:...

El estudio de la distribución y reservas de carbono (C) y nitrógeno (N) en el suelo es de crucial importancia para todos los ecosistemas terrestres, particularmente en zonas secas de montaña donde encontramos alta heterogeneidad debido a las diferencias en suelos, clima y vegetación en relación con la altitud. El objetivo de esta investigación fue...

Full-text available
Phyllopeltula steppae and Reimnitzia santensis from dry forest of southern Ecuador were collected for the first time in Ecuador. The collections constitute the first records of the genera Phyllopeltula and Reimnitzia in the country. We provide information about ecology and distribution of the species.

1. Dryland vegetation is characterized by discrete plant patches that accumulate and capture soil resources under their canopies. These "fertile islands" are major drivers of dryland ecosystem structure and functioning, yet we lack an integrated understanding of the factors controlling their magnitude and variability at the global scale. 2. We cond...
Article
Dispersal, population spatial structure and intraspecific density-dependent processes are critical determinants of plant population dynamics. However, we lack empirical data on how the interplay between these factors changes across the plant species life cycle, particularly for long-lived plants. This is in great part due to the difficulty in imple...
Article
Full-text available
Understanding how diversity is maintained in species-rich communities, such as tropical forests, remains a challenge in ecology. Recent work suggests that the controversy between competing theories could be better resolved by considering the spatial scale at which different processes rule community assembly.Here we use individual species-area relat...

Article
Full-text available
The biogeochemical cycles of carbon (C), nitrogen (N) and phosphorus (P) are interlinked by primary production, respiration and decomposition in terrestrial ecosystems1. It has been suggested that the C, N and P cycles could become uncoupled under rapid climate change because of the different degrees of control exerted on the supply of these elemen...

Project
In the Andes, one of the least studied ecosystems is the seasonally dry inter-Andean scrub. These ecosystems contain an unique diversity and are key to maintaining and connecting biodiversity. Unfortunately, these ecosystems are not protected in Ecuador and are exposed to strong local and global pressures that can and are drastically changing their functioning. The purpose of this project is to understand to what extent Global Changes are modifying the structure and functioning of these ecosystems and the possible consequences on the ecosystem services they provide.
Project
This project will attempt to use of taxonomic and functional diversity of cryptogamic epiphytes as indicators of forests disturbance, air and water pollution in tropical forests (e.g. montane forests, dry forests and lowland forets).
