Searching for learning-dependent changes in the antennal lobe: simultaneous recording of neural activity and aversive olfactory learning in honeybees

Frontiers in Behavioral Neuroscience, 2010
Plasticity in the honeybee brain has been studied using the appetitive olfactory conditioning of the proboscis extension reflex, in which a bee learns the association between an odor and a sucrose reward.

Concentrations of Essential Trace Metals in the Brain of Animal Species—A Comparative Study

Brain Sciences, 2020
The essential trace metals iron, zinc, and copper have a significant physiological role in healthy brain development and function. Especially zinc is important for neurogenesis, synaptogenesis, synaptic transmission and plasticity, and neurite outgrowth.

Multilocus phylogeography and ecological niche modeling suggest speciation with gene flow between the two Bamboo Partridges

Avian Research, 2021
Background Understanding how species diversify is a long-standing question in biology. The allopatric speciation model is a classic hypothesis to explain the speciation process. This model supposes that there is no gene flow during the divergence process

Estimating parameters of speciation models based on refined summaries of the joint site-frequency spectrum [PDF]

, 2011
Understanding the processes and conditions under which populations diverge to give rise to distinct species is a central question in evolutionary biology.

Distinct migratory and non-migratory ecotypes of an endemic New Zealand eleotrid (Gobiomorphus cotidianus) – implications for incipient speciation in island freshwater fish species [PDF]

, 2008
Background: Many postglacial lakes contain fish species with distinct ecomorphs. Similar evolutionary scenarios might be acting on evolutionarily young fish communities in lakes of remote islands.

Perfect association between spatial swarm segregation and the X-chromosome speciation island in hybridizing Anopheles coluzzii and Anopheles gambiae populations

Scientific Reports, 2022
The sibling species An. coluzzii and An. gambiae s.s. are major malaria vectors thought to be undergoing sympatric speciation with gene flow. In the absence of intrinsic post-zygotic isolation between the two taxa, speciation is thought possible through ...

A screen for recessive speciation genes expressed in the gametes of F1 hybrid yeast

, 2007
Diploid hybrids of Saccharomyces cerevisiae and its closest relative, Saccharomyces paradoxus, are viable, but the sexual gametes they produce are not.

The rediscovery of a long described species reveals additional complexity in speciation patterns of poeciliid fishes in sulfide springs [PDF]

, 2013
The process of ecological speciation drives the evolution of locally adapted and reproductively isolated populations in response to divergent natural selection.

How might epigenetics contribute to ecological speciation? [PDF]

, 2013
Speciation research has seen a renewed interest in ecological speciation, which emphasises divergent ecological selection leading to the evolution of reproductive isolation.

Little ecological divergence associated with speciation in two African rain forest tree genera

, 2011
Background The tropical rain forests (TRF) of Africa are the second largest block of this biome after the Amazon and exhibit high levels of plant endemism and diversity. Two main hypotheses have been advanced to explain speciation processes that have led
