Human waste used as nesting material affects nest cooling in the clay-colored thrush
(2021-09-01)
The internal temperature of nests largely depends on the materials used in their construction because the characteristics of each material affect the isolation of nest walls. In urban environments, the availability of
natural ...
Messua sp. (Salticidae), the host spider of the polysphinctine Inbioia pivai (Ichneumonidae: Pimplinae)
(2019)
The koinobiont ectoparasitoids of spiders in the Polysphincta genus group are divided into two well-supported clades. Species in one clade parasitize spiders in the higher araneoid group, and the behaviour of these ...
Elevational and seasonal patterns of plant pollinator networks in two highland tropical ecosystems in Costa Rica
(2024-01-11)
Many plant species in high montane ecosystems rely on animal pollination for sexual repro- duction, however, our understanding of plant-pollinator interactions in tropical montane hab- itats is still limited. We compared ...
Differences in web features between two sympatric Leucauge species (Araneae: Tetragnathidae) suggest a trade-off in prey capture strategy
(2021)
The design of orb webs is affected by multiple abiotic (e.g., wind, available space), biotic (e.g., prey availability,
predation), and species specific (e.g., spider size) factors. Thus, some features of each spider web ...
Spiders hanging out in the rain
(2021-03-12)
Behavioural adjustments to changing environmental conditions are advantageous for spiders, as such adjustments likely allow spiders to remain in good hunting sites. Here, we describe the behavioural response of seven ...
Day/night change in orientation of the orb-weaver Azilia guatemalensis (Araneae: Tetragnathidae)
(2021)
Most orb weavers orient downward on their orbs, but here we
describe an unusual pattern of orientation in the tetragnathid
Azilia guatemalensis. This species changes its orientation on the
hub with a consistent day/night ...
Genetic structure in neotropical birds with different tolerance to urbanization
(2022)
Gene flow in birds can be affected by urbanization depending on natural history traits and adaptability
to habitat change. Contrasting results can be expected when comparing species with opposite
resilience to urbanization. ...
Blooming plant species diversity patterns in two adjacent Costa Rican highland ecosystems
(2023-01-12)
The Costa Rican Paramo is a unique ecosystem with high levels of endemism that is geographically isolated from the Andean Paramos. Paramo ecosystems occur above Montane Forests, below the permanent snow level, and their ...
Web building behavior in a wall spider (Oecobiidae) suggests a close relationship with orb-weavers
(2022)
Behavior is often phylogenetically informative and detailed descriptions of
behavior have been used to support taxonomic relationships in several groups, such
as birds, lizards, and arthropods. Web building behavior has ...
Male orientation on vocalization perches could optimize acoustic signal transmission in anurans
(2020-10-20)
Acoustic signals are distorted by vegetation, wind currents, or other sounds when transmitted through the environment. Consequently, vocalizations with features that optimize sound transmission or behaviors that improve ...
