Caldas meets Janzen: Thermal regimes of montane plants and implications for global patterns of speciation

The paper compares elevational and thermal ranges of sister plant species in tropical and temperate mountains, finding tropical species have narrower thermal ranges and greater similarity between sister species, supporting speciation via thermal specialization.

Changes in bird migration phenology over six decades: a perspective from the Neotropical non-breeding grounds

The paper examines changes in bird migration phenology over six decades in Colombia, finding shifts in both spring and fall migration patterns among 12 migratory species.

The role of learning in the evolution of status signalling: a modeling approach

The paper uses simulations to show that learning can maintain honest signaling in evolutionary models, allowing for polymorphic populations with both honest and dishonest signalers.

100+ years of bird survey data reveal changes in functional fingerprints indexing ecosystem health of a tropical montane forest through time

The paper analyzes 100+ years of bird survey data to track changes in the functional fingerprint of a tropical montane forest, revealing shifts in ecosystem health due to species extirpations and additions.

Complete mitochondrial genomes do not distinguish phenotypically distinct lineages of Andean Coeligena hummingbirds

The study finds that complete mitochondrial genomes of phenotypically distinct Coeligena hummingbird lineages show very low genetic differentiation, suggesting incomplete lineage sorting or introgression.

Plumage convergence resulting from social mimicry in birds? A tetrachromatic view

The paper evaluates social mimicry hypotheses for plumage convergence in flycatcher birds using color discrimination models and reflectance measurements, finding deception unlikely but predator-driven selection plausible.

Origin of elevational replacements in a clade of nearly flightless birds - most diversity in tropical mountains accumulates via secondary contact following allopatric speciation

The paper investigates the origin of elevational species replacements in Scytalopus birds, finding that most arise from secondary contact after allopatric speciation rather than in situ divergence.

Systematics, biogeography and diversification of Scytalopus tapaculos (Rhinocryptidae), an enigmatic radiation of Neotropical montane birds

This study investigates the phylogeny, biogeography, and diversification of Scytalopus tapaculos, finding rapid non-adaptive speciation linked to limited dispersal and landscape barriers.

Extreme genetic structure and dynamic range evolution in a montane passerine bird: implications for tropical diversification

The paper uses mtDNA sequence data from a bird species complex to analyze genetic structure and divergence patterns, revealing high lineage diversity and implications for tropical speciation.
