Molecular clocks and archeogenomics of a late period egyptian date palm leaf reveal introgression from wild relatives and add timestamps on the domestication
(2021-06-30)The date palm, Phoenix dactylifera, has been a cornerstone of Middle Eastern and North African agriculture for millennia. It was first domesticated in the Persian Gulf, and its evolution appears to have been influenced by ... -
Molecular data indicate that Rhytidhysteron rufulum (ascomycetes, Patellariales) in Costa Rica consists of four distinct lineages corroborated by morphological and chemical characters
(2009)Rhytidhysteron rufulum is a poorly known, common, pantropical species, capable of utilizing different substrata and occupying diverse habitats, and is the only species of its genus in Costa Rica. We have employed molecular, ... -
Molecular phylogenetics of Maxillaria and related genera (Orchidaceae: Cymbidieae) based on combined molecular data sets
(2007-11)The orchid genus Maxillaria is one of the largest and most common of neotropical orchid genera, but its current generic boundaries and relationships have long been regarded as artificial. Phylogenetic relationships within ... -

Morfología, ecolocalización y uso de micro-hábitat de murciélagos del género Pteronotus (Chiroptera: Mormoopidae) en el Parque Nacional Barra Honda, Costa Rica
(2020)En el trópico hay una gran riqueza de especies de murciélagos insectívoros y esta riqueza se mantiene, en parte, por el reparto eficiente de los recursos ambientales. Estudios sobre la repartición de recursos entre los ... -
Mormodes salazarii (Orchidaceae, Catasetinae), a new species with greenish-white flowers from Costa Rica
(2016)Mormodes salazarii (Orchidaceae, Catasetinae), a new species apparently endemic to Costa Rica, is described and illustrated. It is similar to M. fractiflexa because of its non-resupinate flowers, entire lip and revolute ... -
Morphological adaptations for relatively larger brains in hummingbird skulls
(2018)A common allometric pattern called Haller’s Rule states that small species have relatively larger brains and eyes than larger species of the same taxonomic group. This pattern imposes drastic structural changes and ... -
Morphological and ecological variation of a tropical anoline lizard: are agonistic interactions shaping ecomorphological relationships?
(2018)Ecologists have long been intrigued by which factors influence habitat use by an organism and how communities are structured. However, the links between habitat preferences, morphology, biotic interactions and community ... -
