Abstract Every organism on Earth must cope with a multitude of species interactions both directly and indirectly throughout its life cycle. However, how selection from multiple occupying different trophic levels affects diffuse mutualisms has received little attention. As result, given amalgamates the combined effects mutualists antagonists to enhance own fitness remains understood. We investigated multispecies (frugivorous birds, ants, fruit flies parasitoid wasps) generate traits in seed...

Abstract Extra-pair paternity rates vary markedly across avian taxa, but patterns of variation in this trait have been obscured by a paucity data on closely related species, especially those spanning broad environmental gradients. Here we compare extra-pair among five species the widespread swallow genus Tachycineta . Rates widely group, ranging from 13 to 87% nests having young. The inter-specific within small group swallows has range equivalent that found all Hirundinidae and is close...

Worldwide, the areas covered by native forests are declining while those of tree plantations increasing. This has raised question whether able to preserve forest species. In Argentina, main Pampas region, called talares, endangered and their disappearance is imminent. Although exotic increasing in this role maintaining bird diversity not been studied Argentine Pampas. We compared community attributes vegetation structure talares with plantations. Compared forests, exhibited markedly lower...

Habitat selection by birds is the result of hierarchical decisions that may be based on different cues at spatial scales. However, studies rarely assess patterns multiple scales simultaneously in order to understand processes leading observed patterns. In central Monte Desert, habitat scale, density Pale-breasted Spinetails (Synallaxis albescens) during breeding season higher mesquite (Prosopis flexuosa) open woodlands than creosote (Larrea cuneifolia) shrublands. Causes this pattern...

Ecological restoration requires the social collaboration of all stakeholders. Native plant nursery managers potentially possess substantial knowledge in native cultivation derived from their practical experience, and they could also be consumers information generated by scientists. Furthermore, active involvement various stages projects enhance efficiency ensure successful outcomes. In this study, Argentina associated with were surveyed to assess level exchange scientific community, degree...

The talares represent the main native forest of Buenos Aires province; however, they are in danger. Given their extreme vulnerability, it is not only necessary to promote conservation, but also restoration. plant nurseries a key link restoration projects. In this work, first survey distribution area was carried out characterize and evaluate them as possible nodes. During 2019, surveys these were either person or online. More than 70% concentrated Metropolitan Area objectives comprise...

We present information on a poorly known native tritrophic interaction involving Celtis ehrenbergiana (Klotszch) Liebm. (Cannabaceae), the fruit fly Rhagoletotrypeta pastranai Aczél (Diptera: Tephritidae), and its parasitoid Utetes anastrephae (Viereck) (Hymenoptera: Braconidae) from Buenos Aires, Argentina. Insects were collected 70 trees 950 fruits immatures reared in laboratory. The accounted for 41.8% of all pupae (59 out 141 pupae), whereas 32.6% (46 braconids pupae). Fruit infestation...

The selection of suitable host plants for larval development is critical most herbivorous insects. In this study, we examined plant preferences larvae the Epistrophus white morpho butterfly, Morpho epistrophus argentinus (H. Fruhstorfer), a specialized butterfly that oviposits on few species. many species, species under control ovipositing females and role in minimal. Through field observations, characterized use coastal woodland patches its southernmost distribution range at eastern Buenos...

The Argentine Native Plant Nursery Network (REVINA) links different social actors involved in native plant production, their valorization and the restoration of Argentina’s ecosystems. It is essential to strengthen network order meet country’s goals, considering that nursery community will generate species be primary inputs for projects. In this paper we study network, plants they produce, projects Argentina through survey participants annual meetings REVINA period 2016-2020. We observed has...

Summary Unexploited public areas such as roadsides could provide habitat to help preserve biodiversity in South America, other regions. Our objective was determine the importance of Argentine Pampas for native birds and suggest management strategies. We surveyed inhabiting all seasons determined whether were used habitat. recorded a total 95 species on roadsides, which represents 55% those described from area. Species included specialists grassland, wetland woodland, 4 vulnerable 19...
