Competition and habitat filtering shape Neotropical canopy butterfly communities across a rainfall seasonality gradient

María F. Checa, David A. Donoso, Elisa Levy, Jaqueline Rodriguez et autres

Abstract The stability hypothesis posits that stable environments provide species with predictable resources, where mechanisms that limit similarity, such as competition, are able to drive niche specialization and shape community composition. By contrast, variable and unpredictable environments are expected to allow only …

Diversity and host-networks of saproxylic beetles along a forest recovery gradient in the tropics

Ana Falconí‐López, Nina Grella, David A. Donoso, Heike Feldhaar et autres

The high tree diversity in tropical forests is known to promote diversity of phytophagous insects. This principle should also apply to wood-inhabiting organisms and their interactions with host tree species. As tree biomass, diversity and deadwood diversity increases during the post-agricultural recovery …

Carpenter bees (Apidae: Xylocopa ) of Ecuador: distribution, DNA barcodes and plant interactions

Raul Ontaneda -Gallegos, Emilia A. Moreno-Coellar, Ana Belén García-Ruilova, Fernanda Salazar-Buenaño et autres

Knowledge of the diversity and ecology of carpenter bees ( Xylocopa ) in Ecuador remains limited and scattered. Here, we present the first updated assessment of Xylocopa across Ecuador, including continental Ecuador and the Galápagos Archipelago, based on the examination of 1,351 …

Barcoding Megadiversity: An Arthropod Database from Sites in the Neotropical Eastern Pacific Bioregion

Ana B. García‐Ruilova, David A. Donoso, Yves Basset, Julio C. Carrión-Olmedo et autres

We present the first dataset collection of arthropod diversity from ten terrestrial sites in the Neotropical Eastern Pacific Bioregion, in the territories of Costa Rica, Ecuador, Panama, and the Galapagos and Cocos Islands. The twenty-five datasets comprise 1-7 years of sampling. Together, …

Biodiversity resilience in a tropical rainforest

Timo Metz, Nina Farwig, Carsten F. Dormann, H. Martin Schaefer et autres

Abstract The UN Decade on Ecosystem Restoration aims to stop biodiversity losses 1 . Approximately 60% of tropical forests have already been lost or severely degraded 2 , making restoration essential to achieve conservation goals. Recovery trajectories of trees have been studied …

Diversity and co-occurrence patterns of wood inhabiting insects along a tropical forest regeneration gradient

Nina Grella, Ana Falconí-López, David A. Donoso, Jörg Müller et autres

More than 90% of global carbon released during dead wood decomposition comes from the tropics, where insects contribute significantly to this process, especially in lowland rainforests. Understanding community assembly of dead wood-inhabiting insects is therefore important. We investigated diversity patterns between habitats …

Understory frog communities recover quickly during tropical forest regeneration

Karla Neira‐Salamea, Arianna Tartara, Leonardo de la Cruz, Felicity L. Newell et autres

Millions of hectares of tropical forest have been lost to agriculture, posing a major threat to biodiversity. However, where agricultural activities do not cause irreversible damage, forests can regenerate after abandonment, forming secondary forests that are increasingly important for conserving forest species. …

Goat land degradation reduces richness and reshapes the functional composition of an ant community in a tropical dry forest

Pamela Gusmán Montalván, Diego P Velez-Mora, Pablo Ramon, Elizabeth Gusman Montalván et autres

Abstract Tropical dry forests are among the world’s most threatened ecosystems, having lost over 60% of their original extent due to agricultural expansion and livestock grazing. Despite a growing body of research on the effects of deforestation and habitat fragmentation, the consequences …

From agriculture back to tropical rainforest: When does ecological succession stabilize hot and dry extremes?

Felicity L. Newell, E Villa-Galaviz, Constance J. Tremlett, Sebastián Escobar et autres

• Land use affects daytime but not nighttime microclimate in lowland tropical rainforest. • Two-thirds of reductions in Tmax occurred in the first decade of natural regeneration. • Full recovery of Tmax required 30–40 years for cacao and 50–80 years for pasture. …

Disparate recovery of phylogenetic diversity across taxa during tropical rainforest regeneration

Sebastián Escobar, María-José Endara, Nico Blüthgen, Gunnar Brehm et autres

Tropical forests are highly threatened habitats with the capacity to recover after disturbance. We studied the recovery of phylogenetic diversity (PD) and phylogenetic community structure in plants and animals along a chronosequence of regeneration. We tested expected phylogenetic patterns through succession, including …

Habitat filtering, not dispersal limitation, drives ant and termite community assembly along a tropical forest regeneration gradient

Nina Grella, David A. Donoso, Jörg C. Müller, Ana Falconí‐López et autres

Abstract Regenerating forests comprise a significant proportion of tropical forest ecosystems, yet species assembly mechanisms after anthropogenic disturbances remain poorly understood. Locally established ant communities follow predictable paths along forest regeneration gradients, but whether this results from dispersal limitation or habitat filtering …
