The year 2007 was stamped with the warmest winter (2006/07) and spring ever recorded since the beginning of measurements in 1864. The vegetation did strongly react to that situation. In the phenological year 2007, 21.3% of the dates of phenological observations were registered as new records, i.e. they were never recorded so early before at that location. This extremely early development of the vegetation could be observed above all in spring and even stronger in summer. The absolute record has been observed when the black elder flowered with 64.5% record-breaking dates. The phenological autumn was not so extreme. However, a strong tendency toward early leaf colouring and leaf fall could be registered. The phenological year 2007 is unique in the history of phenological observations made by Meteo Swiss, which started in 1951.

Biodiversity Changes

The unprecedented rates of current biodiversity loss have motivated a renewed interest in environmental and biodiversity monitoring. The need for sustained monitoring strategies has prompted not only the establisment of new long-term monitoring programmes, but also the rescue of data from historical or otherwise archived sources. Amongst the most valuable datasets are those containing information on intertidal systems, as they are particularly well suited for studying the biological effects of climate change. The Portuguese rocky coast is quite interesting for studying the effects of climate change on the distribution of species due to its geographical orientation, latitudinal patterns in temperature, species richness, species' distribution patterns and availability of historical information. This work aims at providing a comprehensive picture of the distribution and abundance of intertidal macro-invertebrates and macro-algae along the Portuguese rocky coast in the early 2000s. This study provides a description of the rocky shore intertidal biodiversity of the mainland Portuguese coast in the early 2000s. The spatial distribution and semi-quantitative abundance of a total of 238 taxa were assessed at 49 wave-exposed locations. These data provide a comprehensive baseline against which biodiversity changes can be effectively and objectively evaluated.

The present study investigated the timing and duration of phenological events of A. indica in different elevational range Kumaun Himalayan forest. A total of  four sites at elevation ranging between 1,900m and 2,200m were selected and at each site 10 s were marked for observations. The phenological events, i.e. leaf bud formation, leaf bud busting, leafing, flowering bud formation, flowering bud busting, flowering, fruit/seed formation, seed fall and leaf fall were monitored. Phenological duration and asynchrony of these phenophases were determined at 10 day intervals and every 2-3 day intervals during the period of peak activities. The minimum length displayed leaf bud formation (44 days) and maximum by leaf fall (86 days) across the elevation. The environmental conditions, particularly temperature, affected the phenological patterns of A. indica. The leaf bud busting activity of A. indica was 51 days. Flowering activity started on May 1st and was extended over 76 days until July 15th. Seed fall activity was extended over 66 day across elevations. ANOVA showed the longevity of phenophases were varied significantly respective to elevations (p<0.05). Our observation showed that all the phenological events of A. indica appear early at lower (1900 m) and are delayed with increasing elevation. All corresponding  phenological events were earlier at lower elevations because the optimum (9.0 to 19.5°C) is met earlier in these conditions.

Phenological Phases

In 2009, average temperatures above the norm, and in particular the extremely warm months of April, May and August, significantly influenced the development of vegetation in Switzerland. In contrast, the drought that prevailed temporarily did not influence this development. The growing season began in normal time or slightly delayed with hazel flowering in March. Few weeks later, at the time of the last spring phenological phases, vegetation was early, in particular the beech leaf unfolding. A warm April and unusually high temperatures in May are responsible for this turnaround. The early arrival of phenological summer was truly exceptional, with some new record dates. Thus, in summer 2009, due to the heat in May and August, an advance of vegetation development of two to three weeks compared to the standard was temporarily observed. Unlike most previous years, the fall of 2009 showed a clear trend to the late occurrence of autumnal phenological phases that are leaf colouring and leaf fall.

Importance of phenology has increased in view of global climate change. Reproductive phenology is responsible for success in seed production and thereby perpetuation of a species. Phenological studies were not given much importance,especially in the region of Holalkere and Hosadurga of chitraduga district of Karnataka state. Hence, attempt was made to study the phenological aspects of the genus Indigofera L. of sub family papilionoideae in the study area. The phenophases viz., leafing, flowering and fruiting and leaf fall are observed for 10 recorded species of the genus Indigofera. The regular Phenological period of the majority of genus was studied,variation in the phenophases of some small herbs and undershrubs was noticed with respect to its ecology. This investigation gives phenological database of the economically important genus Indigofera of the study area. This database can be also utilized, besides this importance, in future, in planning and management of conservational measures in the region.
