Introduction
My research aims to understand the structure and functioning of biological communities: how biodiversity and species interactions affect community structure and stability, and how they affect the functioning of ecosystems. My research interests include: (i) structure and dynamics of complex ecological networks, (ii) community response to perturbations (habitat loss, climate change), (iii) community patterns at different spatial and temporal scales, and (iv) sustainable agriculture and restoration dynamics.

Article
Full-text available
Ecosystem recovery from anthropogenic disturbances, either without human intervention or assisted by ecological restoration, is increasingly occurring worldwide. As ecosystems progress through recovery, it is important to estimate any resulting deficit in biodiversity and functions. Here we use data from 3,035 sampling plots worldwide, to quantify...
Article
The relationship between structure and stability in ecological networks and the effect of spatial dynamics on natural communities have both been major foci of ecological research for decades. Network research has traditionally focused on a single interaction type at a time (e.g. food webs, mutualistic networks). Networks comprising different types...
Article
Biodiversity increases the ability of ecosystems to provide multiple functions. Most studies report a positive relationship between species richness and the number of ecosystem functions. However, it is not known whether the number of functional groups is related to the structure of the underlying species interaction network. Here we present food w...
Article
Species introductions have the potential to affect the functionality and stability of ecological communities, but because little is known about how introduced species form novel interactions, these impacts are difficult to predict. We quantified the impacts of species introductions on species interaction networks using five different model scenario...
Article
Full-text available
Given the large-scale anthropogenic alteration of natural habitats, ecological restoration is emerging as one of the most important disciplines in environmental science. Once habitats are physically restored, an important goal of restoration is to recover the ecosystem services provided by the diversity of species and their interactions (e.g., seed...
Article
Full-text available
Larger geographical areas contain more species—an observation raised to a law in ecology. Less explored is whether biodiversity changes are accompanied by a modification of interaction networks. We use data from 32 spatial interaction networks from different ecosystems to analyse how network structure changes with area. We find that basic community...
Article
This year’s UN Climate Change Conference (COP26) will be held in Glasgow in November, and now more than ever before, the pressure is on for world leaders to agree on climate action to keep global warming below 1.5°c. In the lead up to the conference, we’re asking our editors and authors to share their research at the interface of climate and ecolog...
Article
Global change degrades ecosystems worldwide. Scientific research has advanced our knowledge of the impacts of global change on ecosystems. Comparatively, however, it remains unclear how ecosystems recover after disturbances. In this perspective, I contend that ecological restoration should advance toward a general, dynamic theory that describes the...
Article
Ensuring stable food supplies is a major challenge for the 21st century. There is consensus that increased food production is necessary, but not sufficient, to achieve food security, and that agriculture should also aim at stabilizing crop production over time. In this context, biodiversity‐based approaches to food security are increasingly being s...
Preprint
Full-text available
Ensuring stable food supplies is recognized as a major challenge for the 21st century. Biodiversity-based approaches to food security are increasingly being supported based on the fact that biodiversity can increase and stabilize crop yields. But agricultural systems are often highly fragmented and it is unclear how such fragmentation affects biodi...
Article
Multiple large-scale restoration strategies are emerging globally to counteract ecosystem degradation and biodiversity loss. However, restoration often remains insufficient to offset that loss. To address this challenge, we propose to focus restoration science on the long-term (centuries to millennia) re-assembly of degraded ecosystem complexity in...
Article
Full-text available
In network ecology, landscape-scale processes are often overlooked, yet there is increasing evidence that species and interactions spill over between habitats, calling for further study of inter-habitat dependencies. Here we investigate how species connect a mosaic of habitats based on the geography of their mutualistic and antagonistic interaction...
Article
Ecosystems worldwide are experiencing the consequences of global change, including those related to climatic warming and the destruction and fragmentation of natural habitats. These factors erode biodiversity and change biological communities and ecosystem processes that are ultimately responsible for the ecosystem services that nature provides to...
Article
We welcome the opportunity to further discuss our analysis and conclusions [1] that Larkin et al.'s [2] (hereafter LEA) comment provides. In this response, we first discuss mischaracterizations and criticisms of our analyses, then highlight how the main conclusions from both LEA's and our analyses are similar, and end with further discussion of wha...
Article
Full-text available
Habitat loss (HL) affects species and their interactions, ultimately altering community dynamics. Yet, a challenge for community ecology is to understand how communities with multiple interaction types—hybrid communities—respond to HL prior to species extinctions. To this end, we develop a model to investigate the response of hybrid terrestrial com...
Article
Full-text available
Changes in land use generate trade‐offs in the delivery of ecosystem services in agricultural landscapes. However, we know little about how the stability of ecosystem services responds to landscape composition, and what ecological mechanisms underlie these trade‐offs. Here, we develop a model to investigate the dynamics of three ecosystem services...
Preprint
Full-text available
Agricultural management should consider multiple services and stakeholders. Yet, it remains unclear how to guarantee ecosystem services for multiple stakeholders′ demands, especially considering the observed biodiversity decline and current global change predictions affecting the mean and variability of ecosystem service provision. Here, we use a m...

Article
Full-text available
Given that few ecosystems on the Earth have been unaffected by humans, restoring them holds great promise for stemming the biodiversity crisis and ensuring ecosystem services are provided to humanity. Nonetheless, few studies have documented the recovery of ecosystems globally or the rates at which ecosystems recover. Even fewer have addressed the...
Article
Full-text available
Global forest restoration targets have been set, yet policy makers and land managers lack guiding principles on how to invest limited resources to achieve them. We conducted a meta-analysis of 166 studies in naturally regenerating and actively restored forests worldwide to answer: (1) To what extent do floral and faunal abundance and diversity and...

Human activities have led to the loss of habitats and biodiversity in the Atlantic Rain Forest in Brazil. Ecological restoration aims to rebuild this biome and should include not only the reinstatement of species, but the reestablishment of complex ecological interactions and the ecological functions that they provide. One such function is seed dis...

Article
Full-text available
Most evidence of climate change impacts on food webs comes from modern studies and little is known about how ancient food webs have responded to climate changes in the past. Here, we integrate fossil evidence from 71 fossil sites, body-size relationships and actualism to reconstruct food webs for six large mammal communities that inhabited the Iber...
Article
There is evidence that broad-scale species richness patterns of woody plants correlate with contemporary gradients of environmental energy inputs and water availability. However, climate-richness relationships for herbaceous species are less well known. Here we analyze the seed-bearing flora of Great Britain, quantifying the relationships between t...
Article
In fragmented landscapes the relationship between the probability of occurrence of single species and the amount of suitable habitat is usually not proportional, with a threshold habitat level below which the population becomes extinct. Ecological theory predicts that, although the reduction in species’ occurrence probabilities (and eventually the...
Article
Aim To evaluate the ability of species distribution models (SDMs) to predict the spatial structure of tree species within their geographical ranges (how trees are distributed within their ranges). Location Continental Spain. Methods We used an extensive dataset consisting of c. 90,000 plots (1 plot km−2) where presence/absence data for 23 common Me...
Article
A major focus of geographical ecology and macroecology is to understand the causes of spatially structured ecological patterns. However, achieving this understanding can be complicated when using multiple regression, because the relative importance of explanatory variables, as measured by regression coefficients, can shift depending on whether spat...
Article
Ecological studies show that species not equally decline following habitat destruction, and suggest that underlying biological processes, such as dispersal type, might be determining the ecological sensitivity of species to habitat loss. There is, however, uncertainty as to how these mechanisms scale up to large scales and generalize across ecosyst...
Article
Studies suggest that populations of different species do not decline equally after habitat loss. However, empirical tests have been confined to fine spatiotemporal scales and have rarely included plants. Using data from 89,365 forest survey plots covering peninsular Spain, we explored, for each of 34 common tree species, the relationship between pr...

Full-text available
We compiled 46 broadscale data sets of species richness for a wide range of terrestrial plant, invertebrate, and ectothermic vertebrate groups in all parts of the world to test the ability of metabolic theory to account for observed diversity gradients. The theory makes two related predictions: (1) In-transformed richness is linearly associated wit...
Article
The length of time land has been available for colonization by plants and other organisms could provide a partial explanation of the contemporary richness gradients of trees. According to this hypothesis, increasing times of land availability entail higher chances of recolonization, which eventually have positive effects on tree richness. To test t...

Question
I'm wondering if there's any empirical relationship of the form Kp ~ F (Fragmentation), where Kp is the carrying capacity of pollinators. Alternatively, I could use Abundance ~ F (Fragmentation). I've seen a study suggestion a power law function, but I'm not sure if there's any sort of universal relationship.
Question
How do you standardize a variable that has positive and negative values? In certain cases standardization reveals a sign switch between unstandardized and standardized coefficients. How can this be solved? Maybe using non-centered (by the mean) standardization?
Question
I am using Generalised Estimating Equations models (an extension of GLMs incorporating spatial correlation) and my response variable has a beta distribution. I have though of transforming the variable or using different family and link functions, but I'm not sure what is the best option. Any help would be appreciated.
Thanks and best wishes
Question
Hi,
I want to measure total Carbon and Nitrogen in soil cores and was wondering how much this analysis costs. Any approximate number would be helpful.
Best wishes
Question
Is it possible to transform a bimodal variable into normal or other 'more friendly' distribution variables? If not, what statistical analysis can be done for a bimodal dependent variable to include spatial correlation? Are Generelized Estimating Equations fit for this purpose?
Question
What are the photosynthetic pathways (C3, C4) of macroscopic algae (Enteromorpha, Ulva) and microscopic diatoms?
Question
I'm searching for any dataset that includes information of species interactions measured at different sites and times (so that spatial & temporal covariance of species is provided). The idea is to test whether or not, and to what extent, food web properties can be predicted from 'easy-to-collect' data (species presence, absence etc.).

Restoration of degraded ecosystems is becoming one of the most important tools to stem biodiversity loss and ensure that ecosystems can sustain future generations. However, studies of the influence of restoration efforts on ecosystem recovery and rates are dominated by projects that use single sites, are carried out over short periods of time, and have unique (and therefore unreplicated) restoration goals, making strategies to maximize restoration outcomes difficult or impossible. The proposed work will synthesise data from over 900 studies worldwide that report on ecosystem recovery from major disturbances - agriculture, damming, eutrophication, hurricanes, invasive species, logging, mining, and overfishing. We will synthesise chrono-sequences to detect patterns in the timing of recovery of biodiversity and ecosystem functions.
