Trophic guild and forest type explain phyllostomid bat abundance variation from human habitat disturbance
(Cold Spring Harbor Laboratory (Estados Unidos), 2020-02-16)The loss of tropical forest cover caused by land-use change is causing a reduction in functional groups, such as trophic guilds. Phyllostomid bats (family Phyllostomidae) are essential in the Neotropics since they occupy ... -
Chromosome-Level Genome Reveals the Origin of Neo-Y Chromosome in the Male Barred Knifejaw Oplegnathus fasciatus
(Elsevier Inc., 2020-04-24)The barred knifejaw, Oplegnathus fasciatus, is characterized by an X1X2Y system with a neo-Y chromosome for males. Here, a chromosome-level genome was assembled to investigate the origin of neo-Y chromosome to the male O. ... -
The interplay between irrigation and fruiting on branch growth and mortality, gas exchange and water relations of coffee trees
(Oxford University Press, 2021)The overall coordination between gas exchanges and plant hydraulics may be affected by soil water availability and source-to-sink relationships. Here we evaluated how branch growth and mortality, leaf gas exchange and ... -
Phytotelm to assess bacterial multi-resistance to the antibiotics in a deep tropical forest
(Research Square Company (Estados Unidos), 2022-02-22)Paradoxically, the use of antibiotics has resulted in the proliferation of resistant microorganisms in environments where they were not thought to be likely to appear. In this context, this research aimed to evaluate the ... -
Life zone and habitat disturbance do not explain the coexistence in Sturnira bat species
(Springer (Alemania), 2022-06-23)One of the key questions in ecology is to understand the mechanisms that modulate the coexistence between syntopic species. Climate and habitat perturbation gradients have been proposed as moderators of species coexistence. ... -
Antimicrobial activity of diverse chemotypes of Lippia graveolens against Aeromonas hydrophila isolated from tilapia
(Cold Spring Harbor Laboratory (Estados Unidos), 2023-07-25)Objetive: This study aimed to evaluate the antimicrobial efficacy of essential oil (EO) from diverse chemotypes of Lippia graveolens against oxytetracycline-resistant Aeromonas hydrophila, which primarily affects the tilapia ... -
The opossum and other didelphids in the cultures of Costa Rican society and indigenous peoples: an approach to ecology and conservation
(Cold Spring Harbor Laboratory (Estados Unidos), 2024)The opossum Didelphis marsupialis, commonly referred to as the zorro pelón in Costa Rica, is a marsupial that holds significant representation in both Costa Rican and indigenous cultures, such as the Talamanca natives. ... -
