How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Sexual System and Female Spawning Frequency in the Sculptured Shrimp Sclerocrangon Boreas (Decapoda: Caridea: Crangonidae) [PDF]

open access: yesJournal of Crustacean Biology, 2009
Abstract The nature of the sexual system (protandry, gonochory) and the frequency of female spawning (semelparous, iteroparous annual, iteroparous biennial) in the crangonid Sclerocrangon boreas remain uncertain. We addressed these questions by examining population sex ratio, anatomy and histology, and gonad and oocyte sizes.

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Development of a prototype of an electronic module that allows to calculate the frequency of spawning in laying hens

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract Poultry farming is an industry recognized worldwide, being one of the main activities in different countries. From the national level, poultry farming is a source of income dedicated to the production of eggs and poultry meat, which has had a constant growth since the mid-twentieth century.

When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

Reproductive Biology of Hemiramphus brasiliensis and H. balao (Hemiramphidae): Maturation, Spawning Frequency, and Fecundity

open access: yesThe Biological Bulletin, 2003
Analyses of life-history data show that both the size-specific batch fecundities and the age-specific spawning frequencies differ for two halfbeak species, Hemiramphus brasiliensis, the ballyhoo, and H. balao, the balao. Halfbeak ages were determined from sectioned otoliths; histological data was used to describe oocyte development and estimate ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Fhod3 in zebrafish supports myofibril stability during growth of embryonic skeletal muscle

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Actin filament organization in cardiomyocytes critically depends on the formin Fhod3, but a role for Fhod3 in skeletal muscle development has not yet been described. Results We demonstrate here that in zebrafish mutated for one of two fhod3 paralog genes, fhod3a, skeletal muscle of the trunk appears normal through 2 days post ...

Embryonic development of the Mediterranean starfish Hacelia attenuata

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...
