Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

open access: yesOikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Butterfly and moth habitat specialisation changes along an elevational gradient of tropical forests on Mount Cameroon

open access: yesOikos, EarlyView.
Niche breadth, reflecting the range of environmental conditions or resources a species can exploit, influences its distribution, persistence, vulnerability to environmental change, and interspecific interactions. The elevational niche‐breadth hypothesis predicts broader ecological niches at higher elevations due to increased environmental stress and ...

Anisotropic community turn‐over at habitat edges informs on assembly drivers: simulation and empirical test on soil macrofauna

open access: yesOikos, EarlyView.
Biodiversity dynamics in heterogeneous landscapes is the result of a complex interplay between movement processes of organisms within and between habitat patches, and niche filtering processes due to spatially varying environmental conditions. Disentangling the relative influences of these different processes on community assembly and dynamics is a ...

Patterns of Larval Development

2020
Abstract In this chapter, we explore the different patterns of development following the hatching of the crustacean larvae. For many groups of crustaceans, the free-living, postembryonic, and prejuvenile phase is by far the most important part of their life cycle, providing the link between different life modes in successive phases (e.g.,

Development of Larval Body Wall Muscles

International Review of Neurobiology, 1999
Publisher Summary Larval muscles in Drosophila form a complex pattern of contractile fibers that attach to the inner surface of the developing epidermis. Each segment has its own, highly specific set of muscles, but from the point of view of the neuromuscular junction, most attention has been focused on the muscles of the abdominal segments.

Mosquito hexamerins: characterization during larval development

Insect Molecular Biology, 1997
We report here the first examination of hexamerins expressed during mosquito larval development. Haemolymph proteins from fourth‐instar larvae of six species representing the two major subfamilies of mosquitoes were characterized by immunoblotting using antisera to calliphorin, the major hexamerin of the blowfly,

Arrested larval development in cattle nematodes

Parasitology Today, 1987
Most economically important cattle nematodes are able to arrest their larval development within the host - entering a period of dormancy or hypobiosis. Arrested larvae have a low death rate, and large numbers can accumulate in infected cattle during the grazing season.

Larval development of Myzostoma cirriferum (Myzostomida)

Journal of Morphology, 2003
AbstractThe larval development of Myzostoma cirriferum is described by means of SEM, TEM, and cLSM. It is similar to that of other myzostomids and includes three stages: the protrochophore, the trochophore, and the metatrochophore. The protrochophore is a ball‐shaped larva present in culture from 18–48 h after egg laying.
