Artificial “dummy” fruits are a very useful method to assess the recovery of potential interactions in restored forests. Most attacks on these dummy fruits are by birds (and some by arthropods or mammals), represented by fruit feeding bird species that are important seed dispersers. Pedro Luna and his team applied …
Trees in tropical rainforest generate a structurally very complex habitat, supporting many niches for a huge diversity of species. But how can this structural complexity be quantified? With a terrestrial laser scanner, Martin Ehbrecht and Tim Lehmann studied the three-dimensional vegetation structure along the chronosequence of ‘Reassembly’. In their recent …
Gunnar Brehm and collaborators have published the first systematic inventory of 330 species of tiger and lichen moths (subfamily Arctiinae, family Erebidae) from the Ecuadorian Chocó. They combined field sampling, DNA barcoding, and phylogenetic analyses to assess species diversity, taxonomic knowledge, and evolutionary relationships. Their results show that only approximately …
In a new contribution, Ugo Diniz and collaborators reveal that tiger moths, often overlooked in pollination research, play a key role as floral visitors. These moths, a highly diverse and abundant group, visit many different plant species, especially those from pioneer plant groups. Even after 40 years of natural forest …
In our study site, herpetologists of our Research Unit, led by Mark-Oliver Rödel’s group at the Natural History Museum in Berlin, discovered an individual of a Toad-Headed Pitviper Bothrocophias that was unknown to occur in the lowland Chocó rainforest in Ecuador. Not only its location, but also its taxonomic identity …
Measuring proboscis length is an essential trait in pollination studies because it influences a bee’s efficiency as a pollinator. However, Frühholz and colleagues showed that existing allometric models developed mainly for temperate species often lack accuracy when applied to tropical bees, leading to under- or overestimation of proboscis length. They …
Ugo Diniz and collaborators investigated the recovery of abundance and diversity in Megalopta, a genus of nocturnal bees, and how these bees respond to the availability of floral resources across a forest regeneration chronosequence. They found that even after 38 years of forest recovery, Megalopta communities had not fully returned …
Anna Landim and collaborators found that animal communities recover more slowly than plant communities, mainly because remnant trees help maintain plant functional diversity and attract animals early in the regeneration process. Their study estimated that animal functional diversity takes about 40 years to reach levels comparable to those of old-growth …
In an unexpected turn, SP2, which usually focuses on frog communities or soil arthropods, has documented the fish diversity of two water bodies in Canandé. Fish act both as predators and as food resources for several animals, including amphibians. This connection allowed F. Griesbaum and coauthors to describe fish diversity …
Acoustic monitoring is becoming increasingly important for evaluating the biodiversity and conservation value of sites across land use or regeneration scenarios. A team led by Jörg Müller and his lab at the University of Würzburg monitored bird sounds using recorders installed in 85 study plots in the Canandé region of …
