Habitat fragmentation reduces plant progeny quality: a global synthesis
(2019-05-14)
Most of the world’s land surface is currently under human use and natural habitats remain as
fragmented samples of the original landscapes. Measuring the quality of plant progeny sired in
these pervasive environments ...
Diversity of deep-sea echinoderms from Costa Rica
(2022-07-31)
Echinoderms are a highly diverse group and one of the most conspicuous in the deep sea, playing ecological key roles. We present a
review about the history of expeditions and studies on deep-sea echinoderms in Costa Rica, ...
Therapeutic potential of hair follicle-derived stem cell intranasal transplantation in a rat model of ischemic stroke
(2022-07-25)
Background
Stem cell-based therapy has received considerable attention as a potential candidate in the treatment of ischemic stroke; however, employing an appropriate type of stem cells and an effective delivery route are ...
Trick or treat? Pollinator attraction in Vanilla pompona (Orchidaceae)
(2021-11)
Natural pollination of Vanilla species remains poorly understood. Our research aimed at better understanding the pollinator attraction mechanism of the Neotropical species Vanilla pompona. Based on our results, we hypothesize ...
