Biannual Spawning and Temporal Reproductive Isolation in Acropora Corals. [PDF]

open access: yesPLoS ONE, 2016
Coral spawning on the oceanic reef systems of north-western Australia was recently discovered during autumn and spring, but the degree to which species and particularly colonies participated in one or both of these spawnings was unknown.

Temporal Dynamics of Reproduction in Hemiramphus brasiliensis (Osteichthyes: Hemiramphidae)

open access: yesThe Scientific World Journal, 2014
The reproductive aspects of Hemiramphus brasiliensis were analyzed with a view to verify the temporal dynamics of reproduction. This paper presents data on sex ratio, length at first sexual maturity, macroscopic and histological aspects of gonad ...

Understanding the Relative Roles of Salmon Spawner Enrichment and Disturbance: A High-Frequency, Multi-Habitat Field and Modeling Approach

open access: yesFrontiers in Ecology and Evolution, 2020
Organisms exert multiple, and often contrasting, influences on ecosystems. During their spawning runs, Pacific salmon (Oncorhynchus spp.) deliver nutrients to freshwater ecosystems, but also disturb benthic sediments during upstream migration and nest ...

Life-history strategies associated to reproduction of three Hyphessobrycon species (Characidae) in lentic environments of upper Paraná River basin

open access: yesActa Limnologica Brasiliensia, 2013
AIM: Life-history strategies in fish include essential parameters related to offspring survivorship, fecundity and time of reproduction, which represent adaptive traits that enable a species to deal with spatial and temporal variability of abiotic ...

Changes in taxonomic and functional diversity of an urban stream fish assemblage: A 30-year perspective

open access: yesFrontiers in Environmental Science, 2023
Globally, freshwater fish diversity is rapidly changing in response to land use change, including urbanization. Time series of freshwater fish communities can help elucidate the underlying mechanisms of species loss and gains, as well as promote ...

New insights into the morphology, reproduction and distribution of the large-tuberculate octopus Graneledone macrotyla from the Patagonian slope

open access: yesScientia Marina, 2012
The new information reported in this paper is based on 11 specimens of the large-tuberculate octopus Graneledone macrotyla. These specimens were caught in bottom trawl surveys ATLANTIS 2009 and 2010 carried out on the Patagonian slope off the Argentinean

Ovarian traits, spawning pattern and season, length at first maturity, and batch fecundity of Caragobius urolepis (Bleeker, 1852) caught from the Vietnamese Mekong Delta

open access: yesHeliyon
Caragobius urolepis has a wide range of distribution, from brackish to freshwater water, ranging from India to the Philippines and Fiji, including the Vietnamese Mekong Delta (VMD), where it lives mainly in the coastal regions and plays a vital role in ...

Still more spawner-recruitment curves: the hockey stick and its generalizations

open access: yes, 2000
Estimation of maximum reproductive rate using spawner-recruitment models involves extrapolating survival for very low spawner abundance. Existing spawner-recruitment curves often lead to biologically unreasonable extrapolations or are unable to model ...
