Disjunct distributions and evolutionary diversification of Australasian geometrid moths: subfamilies Epidesmiinae, Desmobathrinae and Oenochrominae (Lepidoptera) Open
Disjunct distribution patterns have long intrigued biogeographers, sparking ongoing debates about the mechanisms driving the current distribution of biodiversity. Among the most discussed patterns are long-distance dispersal and vicariance…

Illustrated catalogue and preliminary phylogeny of 330 species of Arctiinae moth species from the Chocó rainforest in NW Ecuador: most species are undescribed Open
Tropical rain forests are the most species rich terrestrial habitats on Earth, but their insect diversity is understudied, and it is unclear how many species are already scientifically described. A model group to study description patterns…

Variation in successional niche turnover of multiple taxa in a recovering tropical rainforest Open
Understanding the niche turnover of ecological communities is fundamental for advancing successional theory and effective restoration. However, since niche preferences are known for a few taxa, ecosystem succession is only partially unders…
View article: Recovery of phylogenetic diversity and phylogenetic structure in trees and animals along a chronosequence of tropical forest regeneration
Recovery of phylogenetic diversity and phylogenetic structure in trees and animals along a chronosequence of tropical forest regeneration Open
Tropical forests are highly threatened habitats with the capacity to recover after disturbance. Integrating phylogenies in the study of forest recovery provides key information on the evolutionary relationships of communities through succe…
View article: Moth communities are more diverse in the understory than in the canopy of a tropical lowland rainforest in NW Ecuador
Moth communities are more diverse in the understory than in the canopy of a tropical lowland rainforest in NW Ecuador Open
Tropical rainforests are the most species-rich terrestrial habitats and provide distinct niches for specialization and speciation, in part due to their vertical stratification. Stratification is observed in many insect orders as a result o…
View article: The decades-long recovery of nocturnal bees in logged forests is counteracted by broad resource range and reliance on pioneers
The decades-long recovery of nocturnal bees in logged forests is counteracted by broad resource range and reliance on pioneers Open
Nocturnal bees are elusive pollinators for which little and fragmented evidence of their dietary breadth is available. Moreover, despite their assumed relevance as pollinators of tropical plants, there is no information on how nocturnal be…

Net primary productivity but not its remote‐sensing proxies predict mammal diversity in Andean‐Amazonian rainforests Open
Tropical forests are disappearing, but we have a limited understanding of the factors driving species coexistence in mammal communities of old‐growth forest ecosystems. The total energy that is bound by plants is assumed to be a key factor…

Improving allometric models to estimate the proboscis length of tropical bees Open
The proboscis length of bees is a key morphological trait shaping communities, pollination networks, and likely their responses to habitat loss. Despite its importance, it is rarely considered in ecological studies because of logistic limi…

Is blue the most attractive color for bees? Exploring the attractiveness of colors in vane traps Open
Bees play important roles in shaping ecosystems through processes like pollination. However, their populations are in decline due to habitat degradation and unsustainable agriculture. This study assesses the effectiveness of color traps fo…

Do camera light traps for moths provide similar data as conventional funnel light traps? Open
Insects are of crucial importance for terrestrial ecosystems but many populations decline rapidly. Conventional collecting methods are usually time-consuming, resulting in a low temporal, spatial and taxonomic resolution of data. Automated…

The moth fauna is more diverse in the understorey than in the canopy in a European forest Open
The canopy of forests as the ‘last biotic frontier’ has often been neglected in insect biodiversity studies because it is harder to access compared to the understorey, even in relatively well-known temperate ecosystems. We investigated the…

Region‐specific diversification dynamics and biogeographic history of one of the most diverse families of insects Open
A long‐standing question in evolutionary biology is how historical biogeographic processes have shaped the current diversity of organisms, especially for highly diverse groups. We study the diversification dynamics and biogeographic proces…

Can you trust comparative trait data based on singleton species? Open
Trait measures are affected by intra- and interspecific variability. Most studies aggregate species-level data to averages to analyze patterns of interspecific variation. Reliable per-species averages require data for many individuals per …
