“…In this study, we indeed routinely observed birds and bats during field work as well as other species like Callithrix kuhlii (Wied's marmoset), or Potos flavus (kinkajou) reported in the eastern Atlantic Forest [49], feeding on the Pourouma. Bats are considered good dispersers because they can travel several kilometres each day, and defecate when flying [50] but it is worthy to note that they generally show high fidelity to swarming sites [51][52][53] which should produce highly directional dispersal kernel. Seed dispersal by species identified as legitimate dispersers should occur also mainly in their P95% and may also contribute to the clumping of the animal dispersed species [54].…”

Plant species models are among the available tools to predict the future of ecosystems threatened by climate change, habitat loss, and degradation. However, they suffer from low to no inclusion of plant dispersal, which is necessary to predict ecosystem evolution. A variety of seed dispersal models have been conceived for anemochorous and zoochorous plant species, but the coupling between vegetation models and seed dispersal processes remains rare. The main challenge in modelling zoochoric dispersal is simulating animal movements in their complex habitat. Recent developments allow straightforward applications of hidden Markov modelling (HMM) to animal movements, which could ease generalizations when modelling zoochoric seed dispersal. We tested the use of HMM to model seed dispersal by an endangered primate in the Brazilian Atlantic forest, to demonstrate its potential simplicity to simulate seed dispersal processes. We also discuss how to adapt it to other species. We collected information on movement, fruit consumption, deposition, and habitat use of Leontopithecus chrysomelas. We analysed daily trajectories using HMM and built a deterministic Model Of Seed Transfer (MOST), which replicated, with good approximation, the primate’s movement and seed deposition patterns as observed in the field. Our results suggest that the dispersal behaviour and short daily-trajectories of L. chrysomelas restrict the species’ role in large-scale forest regeneration, but contribute to the prevalence of resource tree species locally, and potentially maintaining tree diversity by preventing local extinction. However, it may be possible to accurately simulate dispersal in an area, without necessarily quantifying variables that influence movement, if the movement can be broken down to step-length and turning angles, and parametrised along with the distribution of gut-transit times. For future objectives, coupling MOST with a DVM could be used to test hypotheses on tree species survival in various scenarios, simulating regeneration and growth at regional scales by including data on main dispersal agents over the area of interest, distribution of tree species, and land use data. The principal advantage of the MOST model is its functionality with data available from the literature as the variables are easy to parametrise. We suggest using the coupled model to perform experiments using only available information, but varying the numbers and species of seed dispersers, or modifying land cover or configuration to test for possible thresholds preventing the extinction of selected tree species.

Hibernation is one of the most important behaviours of bats of the temperate zone. During winter, when little food or liquid water is available, hibernation in torpor lowers metabolic costs. However, the timing of emergence from hibernation is crucial for the resumption of the reproductive process in spring. Here, we investigate the spring emergence of six bat species or pairs of bat species of the genera Myotis and Plecotus at five hibernation sites in Central Europe over 5 years. Using generalized additive Poisson models (GAPMs), we analyze the influence of weather conditions (air and soil temperature, atmospheric pressure, atmospheric pressure trend, rain, wind, and cloud cover) as predictors of bat activity and separate these extrinsic triggers from residual motivation to emerge from hibernation (extrinsic factors not studied; intrinsic motivation). Although bats in a subterranean hibernaculum are more or less cut off from the outside world, all species showed weather dependence, albeit to varying degrees, with air temperature outside the hibernaculum having a significant positive effect in all species. The residual, potentially intrinsic motivation of species to emerge from their hibernacula corresponds to their general ecological adaptation, such as trophic specialization and roosting preferences. It allows the definition of three functional groups (high, medium and low residual activity groups) according to the degree of weather dependence of spring activity. A better knowledge of the interplay of extrinsic triggers and residual motivation (e.g., internal zeitgebers) for spring emergence will help to understand the flexibility of a species to adapt to a changing world.

“…Philopatry is a common feature in female bats which usually return to their natal colony every breeding season, whereas it is generally thought that males tend to disperse in this season (Carter & Wilkinson 2013). Most longevity and long term fidelity cases reported in males are in hibernation roosts (Caubère et al 1984, Podlutsky et al 2005, although recently a case of long fidelity for a swarming roost in a male Myotis bechsteinii has been found in Italy (Bologna et al 2018). The male fidelity for a maternity colony reported here could be explained because, unlike most temperate bats, nursery colonies of R. euryale tend to include many males (Ibáñez 1999).…”

RESUMENLos murciélagos tienen una esperanza de vida inusualmente larga entre los mamíferos, y se encuentran en el extremo lento en el "continuo rápido-lento" de las historias de vida de los mamíferos. En esta nota, informamos la recuperación de un Rhinolophus euryale macho anillado en La Rioja (España) con una edad mínima de 21 años, lo que representa un nuevo récord de longevidad para la especie. Destacamos que este es un caso de fidelidad a largo plazo de un macho a una colonia reproductora y llamamos la atención sobre la aparente contradicción entre la mayor longevidad encontrada en murciélagos machos de acuerdo con los registros de máxima duración de vida, en comparación con la mayor esperanza media de vida y estimaciones de supervivencia que muestran las hembras en los estudios demográficos.
