Stochastic colonization, transient and boom–bust dynamics shape invasions by native taxaNARA Subscribed
Boom–bust dynamics (BBD) is a population dynamic pattern described in invasion ecology, where a population suddenly increases (boom) before quickly declining (bust), eventually stabilizing at much lower levels. This initial outbreak is considered a transient phase preceding a long‐term population equilibrium. If BBD is common in invasions, understanding it is crucial for invasion interpretations and management. Nevertheless, h...
Marine ecosystems have been historically impacted by human activities, leading to significant declines in biodiversity. Despite conservation efforts and the establishment of protected areas over recent decades, many marine species remain threatened. Here, we used a large‐scale database of 308 time series of coastal bird communities collected between 1957 and 2024 across three European regional seas to assess how abundance, tax...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Long transient response of vegetation dynamics after four millennia of anthropogenic impacts in an island ecosystemNARA Subscribed
Agents of global change commonly have a higher impact on island ecosystem dynamics. In the Mediterranean region, those dynamics have historically been influenced by anthropogenic impacts, for example, the introduction of invasive species and overharvesting of resources. Here, we analysed the spatio‐temporal dynamics of vegetation in sa Dragonera island, which experienced a large environmental change ca. 4000 years ago by the a...
Multi-species prey dynamics influence local survival in resident and wintering generalist predatorsNARA Subscribed
Stochasticity in food availability influences vital rates such as survival and fertility. Life-history theory predicts that in long-lived organisms, survival should be buffered against environmental stochasticity showing little temporal variability. Furthermore, to optimize survival prospects, many animal species perform migrations to wintering areas where food availability is larger. Species with large latitudinal distributio...
High frequency of prospecting for informed dispersal and colonisation in a social species at large spatial scaleNARA Subscribed
Animals explore and prospect space searching for resources and individuals may disperse, targeting suitable patches to increase fitness. Nevertheless, dispersal is costly because it implies leaving the patch where the individual has gathered information and reduced uncertainty. In social species, information gathered during the prospection process for deciding whether and where to disperse is not only personal but also public,...
Assessing the effect of density on population growth when modeling individual encounter dataNARA Subscribed
The relative role of density‐dependent and density‐independent variation in vital rates and population size remains largely unsolved. Despite its importance to the theory and application of population ecology, and to conservation biology, quantifying the role and strength of density dependence is particularly challenging. We present a hierarchical formulation of the temporal symmetry approach, also known as the Pradel model, t...
Marine megafauna, including seabirds, are critically affected by fisheries bycatch. However, bycatch risk may differ on temporal and spatial scales due to the uneven distribution and effort of fleets operating different fishing gear, and to focal species distribution and foraging behavior. Scopoli's shearwater Calonectris diomedea is a long‐lived seabird that experiences high bycatch rates in longline fisheries and strong popu...
Varying demographic impacts of different fisheries on three Mediterranean seabird speciesNARA Subscribed
Fisheries have an enormous economic importance, but reconciling their socio‐economic features with the conservation and sustainability of marine ecosystems presents major challenges. Bycatch mortality from fisheries is clearly among the most serious global threats for marine ecosystems, affecting a wide range of top predators. Recent estimates report ca. 200,000 seabirds killed annually by bycatch in European waters. However,...
Current climatic changes have increased the need to forecast population responses to climate variability. A common approach to address this question is through models that project current population state using the functional relationship between demographic rates and climatic variables. We argue that this approach can lead to erroneous conclusions when interpopulation dispersal is not considered. We found that immigration can...
Climate change overruns resilience conferred by temperature‐dependent sex determination in sea turtles and threatens their survivalNARA Subscribed
Temperature‐dependent sex determination (TSD) is the predominant form of environmental sex determination (ESD) in reptiles, but the adaptive significance of TSD in this group remains unclear. Additionally, the viability of species with TSD may be compromised as climate gets warmer. We simulated population responses in a turtle with TSD to increasing nest temperatures and compared the results to those of a virtual population wi...
