III. Representative Bryophyte and Lichen Species of the Miniature Forests of Cape Horn / Especies Representativas de Briofitas y Liquenes de Los Bosques en Miniaturia del cabo de Hornos

Bernard Goffinet and Ricardo Rozzi and Lily Lewis and William Buck and Francisca Massardo University of North Texas Press PDF

Acrocladium auriculatum (Acrocladiaceae)

Characters for field identification: Plants grow horizontally and form highly branched mats, usually with many sporophytes. The branches are spreading and conspicuously pointed. The leaves are broad and spoon-shaped, with hollow blades and rounded apices. The operculum of the capsules are characteristically white.

Habitat: Soil and decaying tree trunks in Nothofagus forests; rocks and live tree trunks in humid

Nothofagus forests

Distribution: Southwestern South America.

Did you know? The characteristic pointed branches have given this moss its generic name

Acrocladium [Acro (tip) + clad (branch)]. The name auriculatum [auricul (auricle) + tum (lobed leaf base)] describes the heart shaped leaves. Many of the names given to bryophytes describe characteristic features of the particular species or genus.

10. The Pleistocene

Fzy, István Indiana University Press ePub

The last 2.6 million years of Earth history following the Tertiary period is called the Quaternary. This period includes the time of the last big glaciation (the Pleistocene) as well as the geological present (the Holocene). The study of the wildlife of the Holocene forms the subject matter of botany, zoology, and anthropology.

During the Pleistocene the large amount of snow that had gradually accumulated in the Carpathian Mountains turned into firn (compacted ice) and subsequently into glacial ice. However, the European continental ice shield, constantly moving from north to south, never reached the Carpathian Basin, which remained a refuge for plants and animals. Deposits of the Ice Age (loess, gravel, sand, and travertine) can nevertheless be found in many places—on the surface or just below it—all over the Carpathian Basin. These sediments can be rich in vertebrate fossil remains, especially mammal bones, and this is one reason why Hungarian Pleistocene research is so well known internationally.

14.1 Introduction

14.1.1  Plant growth-promoting rhizobacteria

The presence of microorganisms, bacteria, fungi, actinomycetes, protozoa and algae is critical to the maintenance and health of soil function, in both natural and managed agricultural soils. This is due to their involvement in key processes such as soil structure formation, decomposition of organic matter, toxin removal, suppression of plant disease and, overall, the cycling of carbon, nitrogen, phosphorus and sulphur (Doran et al., 1996; van Elsas et  al., 1997; Mishra et  al., 2015;

Keswani et al., 2016). Bacteria are the most common of those microorganisms reaching

8 Seed Moisture Testing

Kelanaputra, E.S.; Nelson, S.P.C.; Setiawati, U. CABI PDF

Seed Moisture Testing

8

Abstract

Seed moisture content is critically important for efficient seed processing.

In order to achieve the highest seed germination, the moisture must be controlled: if it is too low, the seed will die; and if too high, it will stimulate fungal growth and result in seed loss during processing.

8.1 Tools

Oven – used to dry seed.

Balance – used to weigh wet and dry seeds.

Glass beaker – used to contain seeds for oven drying.

Hammer – used to crack open seeds to separate the kernel from the shell.

Plastic bag – used to contain cracked seed parts.

Cutter – used to separate the embryo from the kernel.

8.2 Methods

Step 1

The first step is to take seed samples from a representative sample of seed bunches being processed.
