Crop wild relatives are plant taxa that the progenitors of commercial crops and an important genetic resource for improving these making them more resilient in face environmental change. They play role food security it is vital to maintain their natural diversity. However, crop-to-wild gene flow may reduce fitness threaten integrity species long run. Here we investigate purity European apple (M...

Previous research showed that nursery pigs fed deoxynivalenol (DON) contaminated diets supplemented with spray-dried porcine plasma (SDPP) had similar growth rate and feed intake as those consuming noncontaminated diets. In this study, two blocks of 100 weanling pigs were used to determine the optimal inclusion level of spray-dried bovine plasma(SDBP) required in nursery diets contaminated with...

The placoderm fauna of the upper Famennian tetrapod-bearing locality of Strud, Belgium, includes the antiarch Grossilepis rikiki, the arthrodire groenlandaspidid Turrisaspis strudensis and the phyllolepidid Phyllolepis undulata. Based on morphological and morphometric evidence, the placoderm specimens from Strud are predominantly recognised as immature specimens and this locality as representin...

We investigated the nursery role of four coastal ecosystems for the California halibut (Paralichthys californicus) using the following metrics: (1) contribution in producing the fish that advance to older age classes, (2) connectivity of coastal systems resulting from migration of fish from juvenile to subadult habitats, and (3) effect of nursery habitat usage and availability on subadult popul...

A study of nursery stock performance was conducted on four sites in the Tongass National Forest in southeastern Alaska: two sites at Fire Cove (Ketchikan Ranger District [R.D.]) and one each at Anita Bay (Wrangell R.D.) and Eight Fathom (Hoonah R.D.). Containerized Sitka spruce seedlings used in the study were grown at USDA Forest Service nurseries in Petersburg, Alaska, and Coeur d'Alene, Idah...

Although many sharks begin their life confined in nursery habitats, it is unknown how rapidly they disperse away from their natal area once they leave the nursery. We examine this issue in immature lemon sharks (Negaprion brevirostris) from the time they leave the nursery (approximately age 3) at a subtropical island (Bimini, Bahamas), through to the onset of sexual maturity (approximately age ...

To observe the effectiveness of short time in-pond nursery of post larvae (PL) on the survival rate and production of shrimp (Penaeus monodon) under modified improved culture system, an experiment was conducted in earthen ponds at Brackishwater Station of Bangladesh Fisheries Research Institute, Khulna. Results of the experiment revealed that short time in-pond nursery of PL provided the signif...

Using a long-term fisheries-independent data set, we tested the ‘shark nursery area concept’ proposed by Heupel et al. (2007) with the suggested working assumptions that a shark nursery habitat would: (1) have an abundance of immature sharks greater than the mean abundance across all habitats where they occur; (2) be used by sharks repeatedly through time (years); and (3) see immature sharks re...

Feeding low concentrations of DDGS early in the nursery period does not help to maintain growth performance when high concentrations of DDGS are incorporated in the diets during the late nursery period. Summary The objective of this experiment was to evaluate growth performance of weanlingpigs introduced to low concentrations (5%) of DDGS duringphase 2 of the nursery period followed by high con...
