Comparative studies on biomass production, life cycles and composting efficiency of Eisenia fetida (Savigny) and Lampito mauritii (Kinberg)

Although comparative studies of anuran ontogeny have provided new data on heterochrony in the life cycles of frogs, most of them have not included Colombian species. Using different staining techniques, we describe the cranial and poscranial elements development in two hylid species, Scinax ruber and Dendropsophus labialis, providing new data for more comprehensive ontogenetic studies in Neotropical frogs. We examined specimens from Gosner stages 25 to 45. We found differences in the infrarostral and suprarostral cartilages, optic foramen, planum ethmoidale, and the gill apparatus. In the ossification sequence, one of the first elements to ossify were the transverse process of spinal column and atlas in both species, and the parasphenoid in the skull. New descriptions of skeletal development and ossification sequences of larval stages of these two species, especially data concerning the postcranium, contribute with useful information for analysis of sequential heterochrony, because although the hylids are widely known, there are few works (15 of 700 species) about ossification sequence that include the whole skeleton.

Ossification Sequence

Although comparative studies of anuran ontogeny have provided new data on heterochrony in the life cycles of frogs, most of them have not included ossification sequences. Using differential staining techniques, we observe and describe differences and similarities of cranial and postcranial development in two hylid species,Scinax ruber(Scinaxinae) andDendropsophus labialis(Hylinae), providing new data of ontogenetic studies in these Colombian species. We examined tadpoles raining from Gosner Stages 25 to 45. We found differences between species in the infrarostral and suprarostral cartilages, optic foramen, planum ethmoidale, and gill apparatus. In both species, the first elements to ossify were the atlas and transverse processes of the vertebral column and the parasphenoid. Both species exhibited suprascapular processes as described in other hylids. Although the hylids comprise a large group (over 700 species), postcranial ossification sequence is only known for 15 species. Therefore, the descriptions of the skeletal development and ossification sequences provided herein will be useful for future analyses of heterochrony in the group.

Content Type

PurposeThe purpose of this paper is to explore the interface between Lean strategy and organisational transformation by scrutinising the literature on why Lean strategies fail to be implemented and/or sustained.Design/methodology/approachAs a conceptual and research paper, it develops a hypothesis. It encompasses philosophical discussions and comparative studies of others’ work and Lean thinking alongside its links to the principles, ideology, philosophy and underpinning values. The search involved a total of 1,931 articles spanning across 75 different journals. The content analysis approach suggested by Mayring (2004) was selected.FindingsSuccessfully implementing Lean is more complex than often recognized within the literature, and the alignment between strategy and organisational transformation is repeatedly not undertaken. The investigation indicates policymakers need to view Lean as an ideology and not simply another process.Research limitations/implicationsThis paper addresses the inaccurate representation in the concept of Lean as a strategy. While a major evolution has occurred comprising the inputs perceived as imperative for Lean success, a translucent empathy of its philosophy alongside an acknowledgement of the magnitude of the change and transformation necessary has been comparatively perplexing. This paper has implications for academic scholars of strategy and organisational change, as well as for practitioners seeking to implement organisational change.Originality/valueEmpirical evidence suggests that most Lean strategies struggle. Customers are becoming more demanding, markets are becoming more customised, and product life-cycles getting shorter are dictating that Lean needs to be embraced as an ideology.
