Integrating Disturbance, Seasonality, Multi-Year Temporal Dynamics, and Dormancy Into the Dynamics and Conservation of Metacommunities

open access: yesFrontiers in Ecology and Evolution, 2020
The metacommunity framework has rapidly become a dominant concept used by ecologists to understand community assembly. By emphasizing extinction-colonization dynamics, dispersal, and species’ niche requirements in determining community structure ...

Early Life History and Recruitment Processes of a Tropical Anguillid Eel Anguilla marmorata to the Pacific Coast, as Revealed by Otolith Sr:Ca Ratios and Microstructure

open access: yesBiology, 2022
Recent progress in otolith microchemistry especially in strontium:calcium (Sr:Ca) ratios has revealed significant features of life histories in fishes. A catadromous eel, Anguilla marmorata, has the widest distribution among anguillid eels throughout the

Approaches to Dispersing Medical Biofilms

open access: yesMicroorganisms, 2017
Biofilm-associated infections pose a complex problem to the medical community, in that residence within the protection of a biofilm affords pathogens greatly increased tolerances to antibiotics and antimicrobials, as well as protection from the host ...

Aproceros leucopoda (Hymenoptera: Argidae): An East Asian pest of elms (Ulmus spp.) invading Europe

open access: yesEuropean Journal of Entomology, 2010
An invasive sawfly Aproceros leucopoda Takeuchi, 1939, which originates from East Asia, has colonized elms (Ulmus spp.) in Austria, Hungary, Poland, Romania, Slovakia and the Ukraine, at least since 2003.

Dispersal and Repulsion of Entomopathogenic Nematodes to Prenol

open access: yesBiology, 2019
Chemosensory cues are crucial for entomopathogenic nematodes (EPNs)—a guild of insect-killing parasitic nematodes that are used as biological control agents against a variety of agricultural pests.

Dispersal of the Common Cutworm, Spodoptera litura, Monitored by Searchlight Trap and Relationship with Occurrence of Soybean Leaf Damage

open access: yesInsects, 2020
The common cutworm, Spodoptera litura Fabricius (Lepidoptera: Noctuidae) is a major pest of soybean. Pheromone traps are used to monitor male adults, but the catch peaks do not always predict leaf damage in soybean fields.

Larval Behavior and Longevity in the Cold-Water Coral Lophelia pertusa Indicate Potential for Long Distance Dispersal

open access: yesFrontiers in Marine Science, 2017
The life cycle of many marine benthic species includes a pelagic larval stage that governs the connectivity between populations. Larval transport is a function of hydrodynamic and biological processes. Knowledge of how larval traits affect dispersal will

Changing Microarthropod Communities in Front of a Receding Glacier in the High Arctic

open access: yesInsects, 2020
This study was carried out at Ny-Ålesund on Spitsbergen in Svalbard (High Arctic). Eight study sites were established along a transect from the fjord to the snout of the glacier. The sites differed from each other by the type of vegetation cover and soil

Finding a Home: Stopping Theory and Its Application to Home Range Establishment in a Novel Environment

open access: yesFrontiers in Conservation Science, 2021
Familiarity with the landscape increases foraging efficiency and safety. Thus, when animals are confronted with a novel environment, either by natural dispersal or translocation, establishing a home range becomes a priority.

Development of morphology and swimming in larvae of a coral-reef fish, the royal gramma, Gramma loreto (Grammatidae: Teleostei)

open access: yesScientia Marina, 2012
We used reared larvae of Gramma loreto sized 5.5 to 10.5 mm to study ontogeny of morphology and swim- ming. The larvae are slender to moderate in depth, with laterally compressed bodies, about 28 myomeres, a coiled gut that is not compact, extending to
