1. Agriculture as matchmaker of an unexpected mutualism: Great bustard disperses and enhances emergence of domestic olive seeds

Author:
Delibes, Miguel; Corbacho, Casimiro; Calvo, Gemma; Fedriani, José María

Olea europaea; Otididae; birds; feces; forests; fruits; habitats; ingestion; mortality; mutualism; olives; phenotype; planting; saplings; seedling emergence; seedlings; seeds; steppes; summer; Spain
Abstract:
... By changing the habitats and altering plant traits, agriculture has severely disrupted many plant–animal mutualisms. Interestingly, however, the intensification of agricultural practices could also facilitate mutualistic relationships between species with naturally mismatching phenotypes. We illustrate the potential of the great bustard (Otis tarda), a large steppe bird, as disperser of domestic ...

Abstract:
... Incorporating ecological processes and animal behaviour into Species Distribution Models (SDMs) is difficult. In species with a central resting or breeding place, there can be conflict between the environmental requirements of the ‘central place’ and foraging habitat. We apply a multi-scale SDM to examine habitat trade-offs between the central place, roost sites, and foraging habitat in Myotis ...

Elephas maximus; Rusa unicolor; Tectona grandis; conservation areas; correlation; fauna; feces; flora; forests; habitats; herbivores; indigenous species; mithuns; plantations; seedlings; species diversity; trees; understory
Abstract:
... Abandoned plantations could potentially support a large number of native tree species through succession and restore the original tree community. In order to assess the ability of abandoned teak plantations to recover through regeneration, teak stands from 29 to 80 years old were sampled for seedling and sapling density, species richness and the use by large ungulates in the southern Western Ghats ...

Myotis; Pipistrellus pipistrellus; aquatic habitat; constructed wetlands; foraging; nocturnal activity; nutrient retention; ponds; vineyards
Abstract:
... Bats are known to use aquatic habitats as foraging habitats. Agricultural intensification is perceived to be a main reason for the loss of wetlands. However, artificial wetland creation (i.e. the construction of retention-ponds) in the agricultural landscape aiming at water or nutrient retention has recently gained importance. We evaluated to what extent bats use these artificial wetlands as forag ...

5. Diversity change of mountain hay meadows in the Swiss Alps

Abstract:
... We investigated changes in plant diversity in the traditionally fertilised and species-rich Golden Oat meadows by repeating historic grassland relevés from the 1940s in two agricultural areas in the Swiss Alps. The effects of time on alpha and beta diversity at plot level were analysed within the study areas. The specificity of the two study areas was investigated by comparing the variability of ...

6. Estimating changes in species abundance from occupancy and aggregation

Formicidae; fynbos; macroinvertebrates; models; population density; population structure; streams; viability; wildlife management; South Africa; Spain
Abstract:
... Predicting the change in abundance is pivotal for evaluating species’ current conservation status and population viability. Empirical works have suggested that species with an increasing abundance have a more aggregated distribution than those with a declining abundance (namely, the change-aggregation hypothesis, CAH). Here we introduced an improved negative binomial distribution model of the oc ...

7. Herbivore species and grazing intensity regulate community composition and an encroaching woody plant in semi-arid rangeland

Abstract:
... Grazing by livestock can influence ecosystems in various ways, including altering plant communities, influencing woody plant encroachment, and determining livestock productivity. Evaluating long term effects of grazing on plant composition is valuable not only to understand herbivory on rangelands but to be able to address the primary factors that can threaten long term livestock productivity. We ...

Subject:
ecosystems; insects; mammals; seed dispersal
Abstract:
... Seed dispersing animals, ranging from small insects to large mammals, provide a crucial service for a large number of plant species worldwide. However, a decline in dispersers due to direct and indirect threats leads to disruptions of seed dispersal processes. As disperser species are differently susceptible to these threats, consequences for ecosystems are hard to predict. Impacts range from hamp ...

9. Positive effects of shrubs on plant species diversity do not change along a gradient in grazing pressure in an arid shrubland

biogeochemical cycles; grazing; herbivores; nurse plants; perennials; plant communities; shrublands; shrubs; soil; soil quality; species diversity; understory
Abstract:
... Facilitative or positive interactions among species are driven mainly by the environmental amelioration or protection from grazing provided by nurse plants. Some studies have suggested that protection from grazing is inconsequential in water-limited environments because of low herbivore densities and their grazing effects. Others, however, argue that herbivores have a major effect on semi-arid pla ...

Abstract:
... Ant–hemipteran mutualism has a variety of ecological effects on the host plants, but the magnitude and moderators of those effects are poorly known. We evaluated this issue by conducting a meta-analysis based on 49 published studies. Results showed that the mutualism had significant protective effects on the host plans, although those effects did not lead to enhanced plant growth or reproductive ...

11. Use of multiple habitat types with asymmetric dispersal affects patch occupancy of the damselfly Indolestes peregrinus in a fragmented landscape

Subject:
adults; animals; aquatic habitat; hibernation; landscapes; ponds; spring; statistical models; woodlands
Abstract:
... To appropriately predict the patch occupancy of animals, it is often essential to consider not only the habitat structure but also shifts in the habitat requirements of animals with changes in life stage. In addition, asymmetric dispersal among different types of habitat patches is likely to accompany use of multiple habitat types due to differences in the ease with which migrants can find the hab ...
