| Abstract | Maternal effects directly and indirectly modify an offspring’s phenotype during development, preparing the offspring for an environment similar to an environment experienced by the mother. Evolutionarily, this could be adaptive if organisms did not experience a large amount of environmental variation across generations. We argue increased anthropogenic changes have led maternal effects to be maladaptive in plants. Similar problems in humans have been proposed, where metabolic diseases may be increased by a mismatch between the in utero environment and the adult environment; often referred to as the Barker Hypothesis. Plants may experience similar metabolic and functional disorders, caused by maternal effects generated from unreliable environmental cues. In the last 200 years, human activities have increased habitat fragmentation, changed patterns of nutrient deposition, and increased climatic variation within and among years. In this manuscript, we suggest that ecologists should consider the increased negative influence of maternal effects on plant growth and reproduction in spatially fragmented and temporally stochastic landscapes. Several implications for conservation and research arise from this discussion: (1) researchers should focus on evolutionarily relevant measures of spatial and temporal heterogeneity, (2) the maternal history of seeds used for population restoration should be considered, and (3) contiguous habitats should be constructed to reduce the impact of evolutionary traps. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
