Tie them up tight: wrapping by Philoponella vicinaspiders breaks, compresses and sometimes kills their prey
(2006)
We show that uloborid spiders, which lack the poison glands typical of nearly all other spiders, employ thousands of wrapping movements with their hind legs and up to hundreds of meters of silk line to make a shroud that ...
Song plasticity over time and vocal learning in clay-colored thrushes
(2015)
Songbirds have been traditionally classified into close-ended or open-ended learning species according to the length of the sensitive period during which birds are able to memorize new vocalizations. Closed-ended learners ...
Characteristics of male Spot-bellied Bobwhite (Colinus leucopogon) song during territory establishment
(2012)
In song-learning birds, male song shows a large inter-individual variation that frequently plays an important role in intra- and inter-sexual selection. In other bird groups, such as Galliformes, song learning is absent, ...
Do different methods yield equivalent estimations of brain size in birds?
(2020-08-31)
The ratio of brain size to body size (relative brain size) is often used as a measure of relative investment in the brain in ecological and evolutionary studies on a wide range of animal groups. In birds, a variety of ...
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 ...
Ultrastructure of Deinopis egg sac (Araneae: Deinopidae)
(2014)
Attacks by predators and parasitoids on spider eggs are common. To counteract their negative effect, spiders have evolved a series of behaviours and features related to their egg sacs. In the genus Deinopis (Deinopidae) ...
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 ...
The effect of conspecific density, herbivory, and bamboo on seedling dynamics of a dominant oak in a Neotropical highland forest
(2019-10-17)
Conspecific negative density dependence (CNDD) is one of the main mechanisms
influencing diversity maintenance in tropical forests. Tropical highland forests, in
contrast to most lowland forests, are commonly dominated ...
