Connectivity is a parameter that plays a fundamental role in highly fragmented ecosystems, such as the seasonal tropical dry forest.
Objectives
The objective of this research is to calculate the evolution of fragmentation and the functional connectivity of the Ecuadorian seasonal dry forest from 1990 to 2018, and to compare the Ecuadorian...
Abstract
A new regulation has led to the prohibition of recreational hunting on estates located within Spanish National Parks (NPs). Before the ban, eleven NPs in Spain had already reported negative ecological consequences associated with high densities of wild ungulates. The new situation that has occurred after the ban signifies that policies wi...
The Large Psammodromus (Psammodromus algirus) is a lizard that has flexible antipredator behavior, with a considerable preference for finding shelter in the leaf litter under short scrub, and which rarely uses tree trunks to escape from predators. Nevertheless, few works have studied the microhabitat uses and the antipredator behavior of this speci...

Onychophorans are worms of Cambrian origin that have unclear relationships with annelids, tardigrades and arthropods; they have their own phylum and are remarkable for capturing their prey with an adhesive net that forms in a fraction of a second, and for having species in which the young are fed through a placenta. There is no quantitative review...
There are many local fragmentation metrics, but most can be grouped into four types (composition/area, isolation, edge, and shape), and none of them alone determines the degree of fragmentation of a patch. Here, we grouped together the main fragmentation metrics (area, edge, shape, and isolation) in order to propose a new metric/index, the Patch Fr...
Circadian rhythms of Neotropical lizards have been poorly studied, which represents a problem when designing ecological studies or monitoring such species based on direct observations. In this work, 1000 m-long transects were established in an agroecosystem area of the Ecuadorian coast region to study the activity patterns of Stenocercus iridescens...
Olive groves in the Mediterranean basin have undergone a tremendous increase during the last two decades, with most of the new olive groves being planted on arable land. This conversion may affect habitat suitability for steppe birds, which are associated with arable land and other open-land habitats, such as natural pastures. In this work, we eval...
Aim of the study: Traditional vineyards have, in the last few decades, been transformed into trellis systems, but little research has been carried out into the consequences as regards biodiversity. We compared the abundance and species richness of reptiles in conventional-traditional vineyards and trellis vineyards.
Area of study: The study was co...

Background
Fragmentation and deforestation are one of the greatest threats to forests, and these processes are of even more concern in the tropics, where the seasonal dry forest is possibly one of the most threatened ecosystems with the least remaining surface area.
Methods
The deforestation and fragmentation patterns that had occurred in Ecuadori...
Super high-density olive groves (>800 trees ha⁻¹) are rapidly expanding in olive oil producer countries, which entails a strong modification of the olive growing system with important agronomic, economic, sociocultural, and environmental consequences. Among them, the latter is particularly unknown. The aim of this paper is to bring the attention on...
Private protected areas have recently attained more importance at a worldwide level as regards nature conservation. Particularly, the specific region of Western Ecuador receives hardly any protection from the State, and private reserves could, therefore, be a suitable tool to ensure the preservation of its forests and their associated wildlife biod...
The Coast Region of Ecuador has been dramatically deforested, and most of the remaining natural vegetation is formed of fragmented patches, in which there is little knowledge of wild mammal populations. The objective of this study was to assess the presence and detection rate (DR) of medium and large-size mammals by using camera-traps in fragmented...

Ureides are nitrogenous compounds with a special function in some legume under nitrogen fixing conditions, the ureidic legumes. In this group, ureides are the predominant nitrogen transport molecule from nodules to the upper part, whereas amidic legumes use amides as nitrogen transport compounds. In this study, the ureide levels have been analysed...
Rabbits can successfully avoid their enemies by evaluating the risk of predation. They have various defensive strategies, such as morphological adaptations and behaviours patterns, which enable them to perceive their predators and thus reduce the risk of predation. It is well documented that rabbits recognise the scats of terrestrial predators and...

The range of wild ungulates, and principally that of red deer and wild boar, has expanded throughout the Mediterranean Basin in recent decades. The abundances of these species have also increased dramatically, and they are now attaining densities that often exceed ecologically admissible thresholds. This situation has been favoured by several facto...
Sustainability is a key attribute for the future of the olive grove. Cover crops can be considered as an effective tool to achieve sustainability of olive orchards to reduce soil erosion, improve soil fertility and increase biodiversity. However, wild herbivores may forage on cover crops when natural food resources are scarce. In this study we asse...
Hunting activities are responsible for the translocation and restocking of millions of animals throughout Europe, including the introduction of alien species. In a context of the growing use of game translocations and of increasing concern about the impact of biological invasions, our goal is to review the role of alien species introduced primarily...
Understanding how the diversity of invasive species is geographically distributed and identifying the major drivers of that pattern is a relevant challenge as regards invasion biology. The aim of this paper was, therefore, to identify and characterize those areas colonized by a high number of alien species as a means to provide directional indicati...
Resumen La intensificación agrícola llevada a cabo desde inicios del siglo XX han transformado profundamente los agrosistemas, y como consecuencia, la diversidad animal que albergan se ha visto drásticamente reducida.

The arrival of a new variant of rabbit haemorrhagic disease virus, known as RHDV2, has recently taken place in the native range of the European rabbit (Oryctolagus cuniculus), a keystone species which has undergone a sharp decline over the last sixty years as a consequence of certain harmful factors. Several works have noted the presence of this ne...
In the present study, we evaluated the effect of distance to food from rubbish dumps and colony size on White Stork breeding success. Waste from poultry farms is expanding in the study area and is commonly used by the White Stork as a new food resource, which may explain the increase in the number of breeding Storks in the region. The study was car...
Capsule Accessing extra food from waste dumps increases egg volume and hatching mass in White Storks.
Aim To test how White Storks vary their investment in egg size, especially in last laid eggs, in relation to food
availability, and to improve our understanding of the importance of extra feeding on intra-clutch variation.
Methods The study was car...
As the second largest cause of biodiversity loss worldwide, there is an urgent need to study the dynamics of biological invasions and identify factors limiting the distribution of invasive alien species. In the present study we analyze national-scale hunting bag data from Germany to predict the dispersal of raccoons in the largest non-native popula...
Summary.
The red-legged partridge Alectoris rufa is not only the most important bird game species but also an important prey species for many predators in Iberia. However, its populations have significantly declined in recent decades, principally as the result of agricultural intensification on arable land. Its abundance has also undergone a signif...
Cover crops are an effective means to reduce soil erosion and to provide food and shelter for wildlife. However, in areas of intensive farming, which are characterised by the scarcity of weed communities, wild herbivores may focus their grazing on cover crops, which could make their implementation difficult. In this work, we test whether rabbit gra...
Understanding how non-invasive indicators of diet quality, such as faecal nitrogen (FN), relate to population performance is a valuable asset when assessing the management of wild ungulates. However, the relationships between FN and protein intake may depend on the ingestion of less palatable plants containing high quantities of tannin (which is kn...
In recent decades, the abundance and distribution of certain big game species, particularly red deer (Cervus elaphus) and wild boar (Sus scrofa), have increased in south central Spain as a result of hunting management strategies. The high density of these ungulate species may affect the abundance of epigeous invertebrates. We tested the relationshi...
The European rabbit (Oryctolagus cuniculus L.) is a key Prey species in Mediterranean ecosystems that has declined in its natural ranges as a result of diseases and loss of habitat. This situation has led to the production of wild rabbits in enclosures in which they can acclimate and breed. The efficiency of these enclosures as extensive breeding s...
The landscape in southern Iberia has, over the last four decades, altered as a result of the land abandonment, while the abundance of wild boar Sus scrofa and red deer Cervus elaphus has simultaneously increased, and some key prey species such as the European rabbit Oryctolagus cuniculus have declined. In this work we explore: 1) the relationships...
European rabbit restocking is one of the most frequent actions in hunting estates and conservation projects in Spain, France and Portugal where rabbit is a keystone species. The aim of this work was to review current knowledge regarding rabbit restocking in accordance with the IUCN (1998) guidelines for re-introduction in order to identify gaps in...
Over the past few decades, the wild boar has been undergoing an expansion in Europe, which may have negatively affected small game populations and particularly red-legged partridges. We aim to evaluate the red-legged partridge nest predation by wild boar at high boar abundances by placing artificial nests in nine big game estates. Predation rates w...
Rabbit populations in Iberia remain at low densities in several areas in which their endangered predators still coexist, and the recovery of these populations is therefore urgent if the integrity of Iberian Mediterranean ecosystems is to be maintained. The enhancement of wild rabbit populations has been attempted through the use of in situ extensiv...
Capsule Nests of Cinereous Vultures were found to be located farther from roads, villages and the edge of large vegetation patches. They preferred large vegetation patches containing extensive Cork Oak cover on steeper slopes and with lower solar radiation. Less than 8% of the study area was predicted to be suitable for nesting.Aims To generate a p...
Olfactory signalling is widespread among mammal inter-and intra-specific communication systems. Social mammals use latrines (faecal accumulations) as a communication system, which address the needs of indi-viduals both inside and outside the social group. Latrines are commonly used as olfactory and visual signals for the delimitation of territories...
About half a million rabbits are translocated in southwestern Europe every year for conservation and hunting purposes. However, the success of traditional rabbit restocking is generally extremely low, and this has been attributed to short-term predation by mammalian carnivores. Hence, recent recovery programs have tackled the problem of terrestrial...
The declining rabbit population in the Iberian Peninsula has led hunters and authorities to rear rabbits in captivity systems for their subsequent release. One alternative method to intensive rabbitry systems is the use of extensive breeding enclosures, since they produce animals of greater quality for hunting and conservation purposes. However, so...
