Mankind’s strong dependence on nitrogen (N) began when we started farming and, ever since, we have depended on nitrogen in the soil for plant production. More than a century has passed since the discovery of N as an element until the advent of synthetic fertilizers. Today, after a century of Haber–Bosch innovation, many other endeavors and challeng...

Seed Banks within the Botanical Gardens are an important and useful infrastructure directed to ex situ plant conservation. Along history it was interesting to see how these banks turned to be much more useful on that direction. https://issuu.com/camara_municipal_lisboa/docs/jardins_botanicos_portugueses

Imaginem que estão sozinhos num espaço sem nada ao vosso redor. O que fazem? Como sobrevivem? Qual a vantagem de estarem acompanhados? Com jovens diferentes, com animais e plantas? Como gerem os conflitos para tirar partido do espaço que ocupam? Se não vivemos sós neste mundo e se é melhor viver acompanhado como será com os animais e as plantas? Se...

The 150th anniversary of ecology was celebrated in 2016 with a Round Table discussion at European Parliament, Brussels. It was felt the need to grow a social collective mind of what Ecology, as a science, represents in the present threat world. The date, the 14th September, was chosen because it was in that day Haeckel had published his “Oecologie...

Besides being one of the most popular ornamental bulbs in western horticulture, the Mediterranean genus Narcissus has been the subject of numerous studies focusing on a wide scope of topics, including cytogenetics, hybridization and the evolution of polymorphic sexual systems. Phylogenetic hypotheses based on chloroplast data have provided a backbo...

Soils are being degraded at an alarming rate and thereby also crucial ecosystem goods and services. Nitrogen (N) enrichment is a major driver of this degradation. While the negative impacts of N enrichment on vegetation are well known globally, those on various ecological interactions, and on ecosystem functioning, remain largely unknown. Since Med...

This paper offers a different framework for managing Mediterranean drought carob-tree orchard ecosystems. Two dry-farming systems were compared during two consecutive years: pure productive orchards and mixed orchards in a total of 360 mature trees distributed by 18 plots with areas of 0.55 and 0.30 ha per plot, respectively. Carob, fig, almond and...

Protocols for the conservation of threatened plants are often constrained by the absence of data on germination ecology. However, seed bank managers periodically monitor the viability of stored seed collections using germination tests. Here, we argue that data from those tests can and should be used to provide information on germination requirement...

AimsWe aimed to evaluate the presence of the metal hyperaccumulation trait in the phylogeny of Plantago with emphasis on P. subgen. Coronopus. Considering that P. almogravensis is an Al-hyperaccumulator and that phylogenetic links have been described for other Al-hyperaccumulators, we hypothesized that we would find more Plantago taxa with this acc...

Botanic Gardens are living plant museums, where plants have been arranged according to previous research and discovery in order to be used as a display for public appreciation and learning. Thus, more than ever, they can serve to improve the practice of botany, being able: (i) to drive the continuous exchange of ideas using the ‘old and new’ botany...

Background Previous studies showed that the two main Mediterranean plant functional groups, summer semi-deciduous and evergreen sclerophylls, differ in soil characteristics and nitrate (NO3 −) use strategies: even though summer semi-deciduous plants have higher NO3 − availability than evergreen sclerophylls, NO3 − reduction (i.e., nitrate reductase...

The impact of nitrogen (N) on ecosystem functioning and biodiversity is currently recognized to be increasing worldwide. For that reason, there is an urgent need for strategies aimed at identifying and mitigating N mediated effects. Most studies undertaken at a regional scale regarding N deposition are based on models. However, there is a missing l...

Enhanced nitrogen (N) availability is one of the main drivers of biodiversity loss and degradation of ecosystem functions. However, in very nutrient-poor ecosystems, enhanced N input can, in the short-term, promote diversity. Mediterranean Basin ecosystems are nutrient-limited biodiversity hotspots, but no information is available on their medium-...

Mycorrhizal fungi form ecologically important connections between plants and soils, and although nitrogen (N) enrichment has been implicated in the decline of ectomycorrhizal fungal diversity, they are rarely considered in studies investigating the effects of increased N availability on plant species diversity. This chapter describes the effects of...

Nitrogen (N) enrichment has been pinpointed as a main driver for biodiversity change. Most of our knowledge of effects of increased N availability on ecosystems comes from northern Europe and America. Most other ecosystem types have been neglected. Although Mediterranean ecosystems are N-limited biodiversity hotspots, very little is known about the...

Montados are evergreen oak woodlands dominated by Quercus species, which are considered to be key to biodiversity conservation and ecosystem services. This ecosystem is often used for cattle breeding in most regions of the Iberian Peninsula, which causes plants to receive extra nitrogen as ammonia (NH 3) through the atmosphere. The effect of this a...

Faced with increasing demand for crop production and the detrimental environmental impacts of the excessive use of fertilizers, it is important to use all available tools to increase crop nutrient use efficiency. Nutrient acquisition by plant roots is much influenced by the microbial composition and activity of the rhizosphere. Most crop plants (80...

In Europe there is a huge debate on how to improve science education in scholar curriculum. In practice, changing science teaching pedagogies, towards an inquiry-based science education (IBSE). In this approach the teachers engage the students to develop independent and critical thinking skills, positive attitudes and curiosity towards science. The...

Speciation requires the evolution of reproductive barriers to achieve isolation between species. In this paper, we examine the role of two major pre-zygotic barriers in reducing the chance of F1 hybrid formation between two pairs of Narcissus species. Field experiments were performed over 5 years in eight natural populations to determine whether fl...

Nitrogen (N) has emerged in recent years as a key factor associated with global changes, with impacts on biodiversity, ecosystems functioning and human health. In order to ameliorate the effects of excessive N, safety thresholds such as critical loads (deposition fluxes) and levels (concentrations) can be established. Few studies have assessed thes...

Nitrogen (N) is one of the nutrients most limiting to ecosystem productivity. However, N availability is increasing globally, which may affect ecosystem functions and stability. To understand the role of each ecosystem compartment in the cycling of increased N, we studied the initial response of a nutrient-poor ecosystem, a Mediterranean maquis, to...
