Recientes investigaciones han descubierto que la urraca común es una gran dispersora de bellotas en las zonas abiertas, como lo es el arrendajo euroasiático en los bosques. Además, ambos córvidos usan un método eficaz para almacenar y recuperar bellotas en el que la memoria espacial, al contrario de lo que se pensaba, parece tener un papel secundar...
Seed dispersal is key to forest regeneration and often depends on the behaviour of seed scatter-hoarding animals. However, our understanding of the decision-making of scatter-hoarders and how vegetation structure at different spatial scales affects dispersal patterns remains limited. We studied seed dispersal at the forest edge across multiple spat...
Oak (Quercus spp.) colonization is a slow process especially in Mediterranean environments, with apparent important differences among
species. We do not know the magnitude of differences in colonization of oak species in the Iberian Peninsula and how these differences
are driven by interacting abiotic (e.g., drought) and biotic (e.g., seed dispersa...
Lack of silvicultural management in afforested agricultural land in Spain has led to low diversity stands that are vulnerable to environmental risks. We evaluated the establishment of young plantations (28 years old) with Aleppo pine (Pinus halepensis Mill.) and holm oak (Quercus ilex L.) in an old agricultural land in Central Mediterranean Spain a...
La restauración forestal de tierras agrícolas abandonadas es uno de los grandes retos ecológicos actuales. Diversos factores pueden acelerar o limitar esta restauración en ambientes mediterráneos. El objetivo general de la Tesis Doctoral fue evaluar el efecto de diferentes factores que determinan el reclutamiento de encinas (Quercus ilex) en campos...
Seed dispersal by scatter‐hoarder corvids is key for the establishment of important tree species from the Holarctic region such as the walnut (Juglans regia). However, the factors that drive animal decisions to cache seeds in specific locations and the consequences of these decisions on seed fate are poorly understood.
We experimentally created fou...
The declaration of the United Nations Decade on Ecosystem Restoration 2020‐2030 has established the need to focus on human rights in restoration initiatives, including gender equality. Although this goal raises a need to monitor gender biases on ecosystem restoration, we still lack basic gender information and evaluations on the current situation....
Planted woodland islets can provide seeds for restoring forest ecosystems in Mediterranean old fields lacking seed sources, but other factors than seed arrival can also hinder the establishment of woody species. We experimentally examined factors affecting the emergence, survival, growth, and recruitment of holm oak (Quercus ilex) seedlings juvenil...
La urraca (Pica pica) es un dispersor efectivo de bellotas de encina (Quercus ilex) en espacios agroforestales abiertos. Prefiere ciertos hábitats en el paisaje y sitios concretos dentro de los hábitats para almacenar bellotas. Sin embargo, se desconoce si esos hábitats y sitios seleccionados son los más adecuados para el establecimiento de las enc...
El comportamiento de los animales cuando almacenan semillas determina el patrón espacial de la dispersión de muchas especies de plantas. Este trabajo evalúa el efecto de la territorialidad, la distancia recorrida desde la fuente de semillas y las preferencias espaciales a distintas escalas en el patrón espacial de dispersión de semillas y de plántu...
The EU Biodiversity Strategy for 2030 aims to convert 10% of farmland into high-rich biodiversity
elements, including woodland islets and hedgerows. These elements provide a wide range of
ecosystem services in agricultural landscapes, particularly habitat and propagule dispersion. We have
been investigating natural regeneration of abandoned fields...
For plants with seeds dispersed by scatter‐hoarders, decision‐making by animals when caching determines the spatial pattern of seed dispersal and lays the initial template for recruitment, driving the regeneration of many plant species. However, the mechanism by which animal behaviour shapes seed distributions in spatially complex landscapes is not...
Oak regeneration and the expansion of forested sites in Eurasia rely on acorn dispersal by animals, especially the Eurasian jay (Garrulus glandarius). However, in open agroforestry systems where jays are absent, such as old-fields far from acorn sources, oak recruitment still occurs. We hypothesize that the Eurasian magpie (Pica pica), an abundant...
Restoration ecology is a young scientific discipline with limitations that compromise the
recovery of ecosystem biodiversity and functions. Specifically for forest restoration
planning and assessment, we first recommend measures prior to land use changes to
deal with the common lack of efforts to anticipate and plan restoration. Second, we
suggest...
Introduction. The magpie is the most common corvid in Eurasia, which distribution overlaps with the distribution of many Quercus species. We assessed acorn dispersal of the magpie in a woodland and farmland mosaic. Methods. The study was conducted in Central Spain in a Q.ilex plantation surrounded by old-fields dominated by annual herbs. We used bi...
Scatter-hoarding animals such as corvids play a crucial role in the dispersal of nut-producing tree species. This interaction is well known for some corvids, but remains elusive for other species such as the magpie (Pica pica), an abundant corvid in agroecosystems and open landscapes of the Palearctic region. In addition, the establishment of the i...
lanted woodland islets act as sources of seed that may accelerate woodland development in extensive agricultural landscapes. We assessed a 1-ha plot that was planted with 16 100-m2 islets of holm oak Quercus ilex subsp. ballota seedlings near Toledo (Spain) in 1993. In spring 2014 we measured (1) acorn predation and (2) seedling emergence from seed...
The study was carried out in an urban park of Madrid, in which it was decided to remove part of the prairie, replacing it by a mulch (pine bark). One year after this change in soil cover, infiltration tests were performed using the double ring infiltrometer (Müntz method). In each treatment the number of repetitions was 3. In the infiltration tests...
