Mixed Bat-Hummingbird Pollination Assures Reproductive Success in a Highly Variable Upper Montane Species. [PDF]
Ecol EvolWe investigated the reproductive biology of Callianthe sellowiana, a high‐altitude Atlantic Forest species with traits associated with both bat and hummingbird pollination. Our results show that both pollinator groups are equally effective, and reproductive success is enhanced when both are present, highlighting the functional and temporal ...

Simultaneous Detection of Missing Amphibians and Their Fungal Pathogen in a Biodiversity Hotspot Using eDNA. [PDF]
Mol EcolABSTRACT Since the 1970s, striking amphibian declines in population abundances and presumed extinctions have been recorded globally. The chytrid fungus Batrachochytrium dendrobatidis (Bd) is one of the key drivers of these declines. To investigate the potential role of Bd in the decline of Brazil's amphibians, we first used eDNA metabarcoding to survey

Long-Term Maintenance of Complex Chromosomal Inversion Polymorphism in <i>Drosophila mediopunctata</i>. [PDF]
Ecol EvolIt has become increasingly clear that natural selection favors haplotypes that draw functionally related genes together, often targeting mechanisms that control recombination rates. In this paper, we show that the long‐term maintenance of linkage disequilibrium between linked non‐overlapping chromosomal inversions in a Drosophila species may arise from

Montane diversification as a mechanism of speciation in neotropical butterflies. [PDF]
Ecol EvolWe investigated taxonomic boundaries between two sister montane species using genomic data. SNPs gathered using GBS indicated a strong isolation pattern consistent with morphology, separating all individuals of Actinote alalia from all populations of A. mantiqueira.

Performance of Danaini larvae is affected by both exotic host plants and abiotic conditions. [PDF]
Ecol Evol, 2021 We examined the larval performance of two Neotropical Danaini butterflies when using either a native or an exotic Apocynaceae species as host plant in both field and laboratory experiments. By employing both a bitrophic and a tritrophic perspectives, we showed that the use of an exotic host, combined with abiotic factors, negatively affected larval ...

Functional assembly of tropical montane tree islands in the Atlantic Forest is shaped by stress tolerance, bamboo presence, and facilitation. [PDF]
Ecol Evol, 2021 We assessed functional traits of woody communities in tree islands and grasslands in the montane Atlantic forest. The woody communities are stress‐tolerant and respond to facilitation and bamboo‐encroached tree islands show reduced diversity. This has implications for tree island expansion and their vulnerability to climate change. Abstract Aims Amidst
