Effects of Pleistocene climate changes on species ranges and evolutionary processes in the Neotropical Atlantic Forest [PDF]

open access: yes, 2016
The effects of global glaciations on the distribution of organisms is an essential element of many diversification models. However, the empirical evidence supporting this idea is mixed, in particular with respect to explaining tropical forest evolution ...

Long‐term trends in parasite diversity and infection levels: approaches and patterns

open access: yesBiological Reviews, EarlyView.
ABSTRACT Parasites exist in every ecosystem, affecting nearly all organisms and playing a complex role in human societies. On the one hand, they contribute substantially to biodiversity and support ecosystem stability by performing essential ecological functions.

Two new Eulophinae genera (Chalcidoidea: Eulophidae) from the Neotropical region

open access: yesZootaxa, 2020
Two new Eulophinae genera, Elasmarion and Celesterion, are described based on material from sweep-net and malaise trap samples mainly from Costa Rica. The new genera are each represented by a single species, both described here, E. longipes and C. reticulatum spp. nov. The material for both groups is abundant and strongly female biased, 119 females and

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

The Complete Chloroplast Genome of Guadua angustifolia and Comparative Analyses of Neotropical-Paleotropical Bamboos. [PDF]

open access: yesPLoS ONE, 2015
To elucidate chloroplast genome evolution within neotropical-paleotropical bamboos, we fully characterized the chloroplast genome of the woody bamboo Guadua angustifolia. This genome is 135,331 bp long and comprises of an 82,839-bp large single-copy (LSC)
