Road mortality alters the body size and age structure of amphibians

Oikos, EarlyView.
Road mortality affects a wide range of animal species, including amphibians. Worldwide, many amphibian species, including the Asiatic toad Bufo gargarizans, are impacted by road mortality, but the ecological consequences remain poorly understood. This study aimed to evaluate how road mortality influences population traits by comparing body sizes and ...

Plasticity in parental care: Interspecific competitor cues shape biparental cooperation in a burying beetle

Journal of Animal Ecology, EarlyView.
Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Tadpole renormalization and relativistic corrections in lattice NRQCD [PDF]

, 1998
We make a comparison of two tadpole renormalization schemes in the context of the quarkonium hyperfine splittings in lattice NRQCD. Improved gauge-field and NRQCD actions are analyzed using the mean-link $u_{0,L}$ in Landau gauge, and using the fourth ...

Promoting Methane Reductions Through Behavioural Nudges and Informational Boosts: A Field Choice Experiment in Japanese Rice Farming

Journal of Agricultural Economics, EarlyView.
ABSTRACT Agricultural methane emissions represent a significant contributor to global climate change, with irrigated rice cultivation being one of the primary sources. Despite the availability of effective mitigation technologies, their adoption often remains limited due to behavioural and institutional constraints.

Taxonomic revision and phylogenetic position of Osteocephalus festae (Anura, Hylidae) with description of its larva

ZooKeys, 2010
Osteocephalus festae is an Amazonian species recently resurrected from a synonymy with O. buckleyi. Because few specimens are known, its morphological variation, diagnostic characters, and distribution are poorly understood.

Tadpole Cancellation in Unoriented Liouville Theory

, 2003
The tadpole cancellation in the unoriented Liouville theory is discussed. Using two different methods -- the free field method and the boundary-crosscap state method, we derive one-loop divergences.

Single Cut Integration [PDF]

, 2010
We present an analytic technique for evaluating single cuts for one-loop integrands, where exactly one propagator is taken to be on shell. Our method extends the double-cut integration formalism of one-loop amplitudes to the single-cut case.

The Wonder Years: A Demographic Approach to Revisit the Age‐at‐Size Conundrum in Amphibians

Integrative Zoology, EarlyView.
We combined repeated body size measurements of marked individuals of unknown age throughout their adult life with growth records of individuals marked as postmetamorphic juveniles and recaptured years later as sexually mature adults, focusing on 10 amphibian species in central Spain.

The Cap in the Hat: Unoriented 2D Strings and Matrix(-Vector) Models

, 2003
We classify the possible bosonic and Type 0 unoriented string theories in two dimensions, and find their dual matrix(-vector) models. There are no RP^2 R-R tadpoles in any of the models, but many of them possess a massless tachyon tadpole.

Magnetic fluxes and moduli stabilization [PDF]

, 2006
Stabilization of closed string moduli in toroidal orientifold compactifications of type IIB string theory are studied using constant internal magnetic fields on D-branes and 3-form fluxes that preserve N=1 supersymmetry in four dimensions.
