Bacteria contribute to plant secondary compound degradation in a generalist herbivore system.
(2020)Herbivores must overcome a variety of plant defenses, including coping with plant secondary compounds (PSCs). To help detoxify these defensive chemicals, several insect herbivores are known to harbor gut microbiota with ... -

Bat Assemblages along an Elevational Gradient in Costa Rica
(2022)Spatio-temporal patterns of species richness, Hill numbers, captures per species, feeding guilds, sex ratio, and biomass were studied in a Neotropical bat assemblage during 17 continuous months in four bands (low: 50–150, ... -
Bats mimic hymenopteran insect sounds to deter predators
(2022)This study explores interspecific acoustic mimicry in mammals, particularly focusing on the greater mouse-eared bat (Myotis myotis) distress calls. These calls imitate stinging bee and wasp sounds, aiming to deter avian ... -

Begomovirus de importancia económica que pueden encontrarse en ambientes protegidos
(2015)Los begomovirus (familia Geminiviridae) son un grupo de virus de plantas transmitidos por la mosca blanca Bemisia tabaci (o ‘palomilla’). Las enfermedades causadas por estos patógenos se han propagado a nivel mundial, ... -
Behavioral changes across novelty habituation: Contextual modulation of self-grooming after a stress event
(2018-07)Grooming is a widespread behavior in the animal kingdom primarily geared towards the care of the body surface; nonetheless, other behavioral functions have been investigated and postulated. For example, rodents display ... -
Behavioural responses of reptiles to visitors of protected areas in Costa Rica
(2016)Tourists can have a strong impact on the behaviour of wild animals, modifying foraging strategies, diet and habitat use, increasing stress, and altering communication and escaping behaviour. Such behavioural changes have ... -
Bemisia tabaci Biotype Q is present in Costa Rica
(2011)Whiteflies are an insect group that comprises multiple species and biotypes, capable of affecting crops by phloem feeding, virus transmission and promotion of fungal colonization. The distribution of these pests is worldwide. ... -
Benefits of protection on reef fish assemblages in a human impacted region in Costa Rica
(2019)In recent years, there has been a health decrease in marine ecosystems. Due to this accelerated degradation, there is a more pressing need to investigate the effectiveness of MPAs in these degraded zones. In this work, we ... -
Beyond the various contrivances by which orchids are pollinated: global patterns in orchid pollination biology
(2023)Orchidaceae show remarkable diversity in pollination strategies, but how these strategies vary globally is not entirely clear. To identify regions and taxa that are data-rich and lend themselves to rigorous analyses or are ... -
