Vestiges of an orb-weaving ancestor? The “biogenetic law” and ontogenetic changes in the webs and building behavior of the black widow spider Latrodectus geometricus (Araneae Theridiidae)
(2008)
Young juveniles of L. geometricus fit the strong trend for “ontogeny to repeat phylogeny” previously documented in other web-building spiders; younger spiders were less likely to build the derived silk retreats that occur ...
Construction and function of the web of Tidarren sisyphoides (Araneae: Theridiidae)
(2009)
In this paper, we describe the construction and function of the double sheet and tangle web of Tidarren sisyphoides (Walckenaer 1842). Web construction includes several stages: construction of the scaffolding that serves ...
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 ...
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. ...
Ontogenetic changes in web architecture and growth rate of Tengella radiata(Araneae, Tengellidae)
(2008)
In some spiders features of the webs of early instars may represent features of the ancestor's web. Some second instar spiderlings (first instar outside of the egg sac) of Tengella radiata (Kulczynski 1909) construct a ...
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 ...
