Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations

Biological Reviews, EarlyView.
ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.

Population Genetic Approaches to Speciation of Wild Tomatoes with Special Reference to Solanum habrochaites and S. arcanum [PDF]

, 2009
This thesis entails the results of three research projects. These have focused on the influence of diversity, demography and structure in the divergence (i.e. the speciation process) of four wild tomato species.

Serological and molecular investigation of Neospora caninum in cattle in Al-Diwaniyah province, Iraq

Open Veterinary Journal
Background: Neospora caninum is one of the protozoa that have been identified in recent decades and plays an important role in causing disease in cattle, leading to abortions in pregnant animals. Therefore, to highlight the epidemiology of this parasite

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

Biological Reviews, EarlyView.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Molecular markers, analysis and the population genetics of parasites

, 2002
In this study different molecular techniques are contrasted (RAPD's, allozyme, sequencing mtDNA, sequencing ribosomal spacers) and appropriate analytical methods (allelic and infinite-sites approaches; inbreeding and coalescent models) used for ...

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Investigation and analysis of taxonomic irregularities with the Botryosphaeriaceae

, 2011
Many members of Botryosphaeriaceae live as endophytes with a latent phase that can cause disease in native and non-native plant hosts around the world. The main Botryosphaeriaceae examined in this thesis included species in the Lasiodiplodia theobromae ...

Investigation of neglected bacterial pathogens provides molecular and serological evidence of Bartonella spp. in patients with acute undifferentiated febrile illness in Villeta, Colombia

Parasites & Vectors
Background Acute undifferentiated febrile illness (AUFI) is a challenging clinical condition in tropical regions, caused by a broad range of pathogens. In Villeta municipality, Colombia, data on neglected bacterial causes remain scarce, highlighting the ...

Embryonic development of the Mediterranean starfish Hacelia attenuata

Developmental 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 ...
