Functional changes in web design along the ontogeny of two orb-weavers
Orb webs evolved primarily to capture prey, though they also have other functions. Recently, it has been argued that the orb web does not work as a functional unit, but instead some sections or components have presumably ...
C1 compounds shape the microbial community of an abandoned century-old oil exploration well
The search for microorganisms that degrade hydrocarbons is highly relevant because it enables the bioremediation of these substances cheaply and without dangerous by-products. In this work, we studied the microbial communities ...
Thin-layer black phosphorus/GaAs heterojunction pn diodes
Owing to its high carrier mobility and thickness-tunable direct band gap, black phosphorus emerges as a promising component of optoelectronic devices. Here, we evaluate the device characteristics of p-n heterojunction ...
When a little is enough: cocoon web of Kapogea cyrtophoroides (Araneae: Araneidae) induced by Hymenoepimecis heidyae (Ichneumonidae: Pimplinae)
The final instar larvae of the koinobiont ectoparasitoids in the Polysphincta group of genera induce their host spiders to construct webs that protect the wasp pupa during its development. It has been hypothesized that ...
The water striders (Hemiptera: Heteroptera: Gerridae) of Costa Rica: new species, checklist, and new records
Brachymetra bernaldi Cordeiro, sp. nov. (Hemiptera: Heteroptera: Gerridae) from Heredia, Costa Rica, is herein described, illustrated, and compared with congeners. The new species resembles B. albinervus (Amyot & Serville, ...
Alimentacion de pichones, exito reproductivo y notas sobre cuido parental en yiguirros (Turdus grayi): el rol de las hembras y machos
Nestling feeding, nest success, and notes of parental care in the Clay-colored Thrush (Turdus grayi): the role of females and males
Las hembras frecuentemente invierten ma ́s que los machos en cuido parental, pero en sistemas sociales monogamos, los machos invierten tanto como las hembras en el cuido de su progenie y se estima que esta contribucion ...
