Spectral indices to evaluate the physiological response of Mediterranean shrubs to browsing Open
Herbivory by large ungulates may cause important physiological and spectral changes in plants, which may serve as ecological indicators of herbivore overabundance. This study examines the physiological and spectral response of plants to re…

Overabundant populations of large wild herbivores disrupt plant–pollinator networks in a Mediterranean ecosystem Open
Large herbivores are keystone species, so changes in their population abundance can have cascading effects on ecosystems. Over the last decades, many species of deer (Cervidae) have experienced unprecedented densities across many areas of …

Long-term grazing influences root-associated fungal communities in a common Mediterranean grass Open
Background and aims Ungulates are integral to Mediterranean ecosystems, influencing vegetation dynamics and soil microbial communities. While previous studies have documented the effects of herbivory on the soil microbiome (e.g. nitrogen-f…

Early Detection of Wild Ungulate Herbivory Cessation in Mediterranean Landscapes Using Hill Numbers as Vascular Plant Diversity Indices Open
Herbivory by ungulates is a seminal driving force in Mediterranean landscapes, where habitat diversity contributes to supporting high population densities. We investigated the influence of grazing and browsing, primarily by red deer (Cervu…

Acorn removal and seedling age determine oak (Quercus ilex L. and Q. suber L.) restoration outcome in ungulate-dominated Mediterranean environments Open
Key message We test the potential benefits of planting 2-year vs. 1-year-old seedlings to restore Mediterranean oak-dominated systems. Planting 2-year-old Quercus suber L. seedlings is recommended for improved survival and resilience again…

Deforestation and water availability as main drivers of human-elephant conflict Open
Climate change, land use conversion and human population growth are reducing and fragmenting historical ranges of large animals, especially in Africa. Particularly, land conversion to agriculture is leading to coexistence challenges betwee…

Shrub interaction with oak seedlings under high herbivory pressure: The role of ontogeny, drought, and plant competition Open
Land use changes occurring during the last decades have caused new challenges in forest management of Mediterranean ecosystems, such as overpopulation of wild ungulates. This is causing serious impacts on forest regeneration, particularly …

Infrared barriers as a detection tool to reduce human–elephant conflicts Open
Elephant incursions into farms represent an important challenge for local communities and farmers living around protected areas, but also for the long‐term conservation of elephants. Early detection of elephants is a promising technique to…

The Herbaceous Understory Plant Community in the Context of the Overstory: An Overlooked Component of Tropical Diversity Open
Lowland tropical rainforests harbor the most diverse plant communities in the world, but the herbaceous plants of the understory are often overlooked. To address this knowledge gap, we asked to what extent the understory herbaceous communi…

Exploring the Use of Solid Biofertilisers to Mitigate the Effects of Phytophthora Oak Root Disease Open
Oak forests are facing multiple threats due to global change, with the introduction and expansion of invasive pathogens as one of the most detrimental. Here, we evaluated the use of soil biological fertiliser Biohumin® to improve the respo…

Let Us Give Voice to Local Farmers: Preferences for Farm-Based Strategies to Enhance Human–Elephant Coexistence in Africa Open
Local communities surrounding wildlife corridors and natural reserves often face challenges related to human–wildlife coexistence. To mitigate the challenges and ensure the long-term conservation of wildlife, it is important to engage loca…
View article: Moss cover and browsing scores as sustainability indicators of mountain ungulate populations in Mediterranean environments
Moss cover and browsing scores as sustainability indicators of mountain ungulate populations in Mediterranean environments Open
Here, we aimed to define ecological indicators of environmental change for monitoring the effect of a reintroduced species, the Iberian ibex ( Capra pyrenaica ), over the vegetation of a natural protected area with contrasting habitats. Th…

The role of Baccharis (Asteraceae) shrubs in the short-term restoration of Atlantic rainforest Open
The introduction of nurse species on degraded sites of Permanently Protected Areas represents a useful strategy for vegetation recovery in riparian forest. Species of the genus Baccharis (Asteraceae) have been documented as potential nurse…

Using retrospective life tables to assess the effect of extreme climatic conditions on ungulate demography Open
In Mediterranean areas, severe drought events are expected to intensify in forthcoming years as a consequence of climate change. These events may increase physiological and reproductive stress of wild populations producing demographic chan…

A pressure indicator for the impact of Iberian wild goat on moss and soils in a Mediterranean climate Open
In the Sierra de Guadarrama National Park (central Spain), the population of Iberian wild goat, also known as Spanish ibex ( Capra pyrenaica ) has grown strongly since its reintroduction three decades ago. The plant community is now under …

Effects of Domestic and Wild Ungulate Management on Young Oak Size and Architecture Open
Scattered oaks in traditional silvopastoral systems (i.e., “dehesas”) provide important ecological services. However, livestock intensification applied to these systems over the last century has affected the architecture of young oak plant…

Impact of successive spring frosts on leaf phenology and radial growth in three deciduous tree species with contrasting climate requirements in central Spain Open
Rear-edge tree populations forming the equatorward limit of distribution of temperate species are assumed to be more adapted to climate variability than central (core) populations. However, climate is expected to become more variable and t…
