What drives animal responses to high severity fire? The role of functional traits

Biological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Trophic dynamics of three sympatric anuran species in a soybean agroecosystem from Santa Fe Province, Argentina [PDF]

, 2010
The conversion of forests to agroecosystems presents a challenge for biodiversity conservation. In this study, the feeding habits of three species of anurans (Rhinella fernandezae, Odontophrynus americanus and Physalaemus albonotatus) were ...

Evidence for adaptive explanations of semelparity in animals

Biological 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 ...

Habitat heterogeneity and anuran community of an agroecosystem in the Pantanal of Brazil

Phyllomedusa: Journal of Herpetology, 2014
The Pantanal of central Brazil has experienced considerable modifications as a result of growing land use. The association between anuran assemblage and the local habitat structure of an agroecosystem in central Brazil at the Pantanal is described. It is

Antimicrobial properties of the skin secretions of frogs

South African Journal of Science, 2012
Antimicrobial resistance results in increased morbidity and mortality, and increased health-care costs. Therefore the need to develop new classes of antibiotics is indispensable.

Mechanisms, costs, and carry‐over effects of cannibal‐induced developmental plasticity in invasive cane toads

Ecology and Evolution
Inducible defences can improve survival in variable environments by allowing individuals to produce defences if they detect predators. These defences are often expressed as inter‐related developmental, morphological, and behavioural changes.

The Impact of Sustainability Labelling on Consumers' Evaluation and Choice of Food Products: A Systematic Literature Review

Business Strategy and the Environment, EarlyView.
ABSTRACT The last five years of research on sustainability labelling, reported in 175 journal articles, documents its effectiveness in increasing consumer choices of more sustainable food products. Some sustainability labels come out as stronger than others and their impact varies across products, countries, and individual consumers, depending on label

Love Hug—Functional Validation of Nuptial Pad-Secreted Pheromone in Anurans

Animals
Chemical communication is an important mode of communication in the courtship and breeding processes of amphibians. In caudates, multiple components of sexual pheromones have been identified and functionally verified.

Talk to Me Like a Human: How AI Chatbot Message Tone, Recommendation Type, and Personalization Drive Consumers' Continuance Intention

Journal of Consumer Behaviour, EarlyView.
ABSTRACT This study investigates how artificial intelligence (AI) chatbot message tone, fashion product recommendation type, and personalization level interact to shape consumers' continuance intention in online fashion shopping. Building on Construal Level Theory and the Stereotype Content Model, we treat warmth and competence cues as psychological ...

Feeding Mechanisms in Anuran Tadpoles [PDF]

Nature, 1950
I CAN confirm that the method of mucous cord feeding referred to by Dodd1 plays a part in the natural lives of tadpoles of Rana temporaria, Bufo bufo and Bombina variegata living under natural or semi-natural conditions. It is, however, remarkable that among the many tadpoles which have been examined, definite mucous cords have been seen in only a few.
