Phenology, pollen synchronization and fruit characteristics were studied during the season 2011-2012 for European hazelnut (Corylus avellana L.) cv. "Tonda di Giffoni" and three of its pollinizers ("Tonda Romana", "Tond...

Abstract Spawning underpins fish stock regeneration. Here, we investigate climate effects on spawning phenology in Atlantic cod (Gadus morhua), a severely exploited species whose stocks are now also affected by climate c...

Understanding how vegetation phenology is changing across dryland agricultural systems is crucial for predicting the effects of climate change and enhancing food system resilience. Here, we analyze two decades of seasona...

Soluble carbohydrates distribution depends on plant physiology and, among other important factors, determines fruit yield and quality. In plant biology, the analysis of sugars is useful for many purposes, including metab...

We studied the spatio-temporal variations of satellite chlorophyll-a (chl-a) and phytoplankton blooms in the continental shelf and shelf-break of the Argentinean patagonic region by means of an 11-years time series of le...

ABSTRACT We investigated intensity and seasonality of the reproductive phenology of Passiflora cincinnata Mast. and estimated its flowering and fruiting periods by interpolation using Inverse Distance Weighting, for the ...

Abstract Climate warming advances the start of the growing season and enhances carbon uptake on the Qinghai-Tibet Plateau, primarily through the direct effects of air temperature and precipitation. However, the role of s...

Perennial plants which flower and fruit once in their lifecycle and then die are known as plietesial monocarpic. Many species from the family Acanthaceae are known for this behaviour. With the detailed phenological obser...

Objetivou-se avaliar o efeito da altura (10 e 20 cm) e do intervalo de cortes (30 e 45 dias) na produção de sementes de capim-melador (Paspalum dilatatum Poir.) em condições de campo. As plantas foram cortadas nove e...

Anthropogenic alteration of tropical and subtropical forests is a major driver of biodi-versity loss, with the Chaco forest, the largest dry forest in the Americas, among the most impacted regions. Sustainable forest man...

With their ground-nesting habits, the Red-wattled Lapwing Vanellus indicus are particularly vulnerable to urbanization, which ffects their nesting behaviour, reproductive success, and habitat use. The present study was...

Speciation through homoploid hybridization (HHS) is considered extremely rare in animals. This is mainly because the establishment of reproductive isolation as a product of hybridization is uncommon. Additionally, many t...

ABSTRACT The present study consists of the floristics-taxonomic survey of Bromeliaceae and Orchidaceae on rocky outcrops located at an Atlantic Forest-Caatinga transition area in Paraíba State, northeast of Brazil, in o...

The present paper highlights the extended distribution of aquatic herb Nymphoides peltata (S.G.Gmel.) Kuntze and presents as a new addition to the flora of Manipur. This study also provides phenology, conservation status...

Despite their charismatic appeal and threatened conservation status, parrots of the genera Tanygnathus and Prioniturus remain poorly studied throughout their range. Their inconspicuous behaviour, elusive nature, and rari...

apria himalayana Griff. f. albovinosa Banziger & Hansen (Rafflesiaceae) is rare and endemic to northeastern Thailand, Vietnam, and Manipur, with a short flowering season ranging from late October to late November, due to...

Field surveys and exploration studies in natural forest vegetations in the hill and the central valley areas of Manipur led to documentation of four species under four genera and four families of Angiosperms. The species...

Abstract Durum wheat breeding increasingly requires tools that can anticipate how genotypes respond to the shifting mix of heat and drought typical of Mediterranean drylands. In this study, we explored whether a multimod...

Background The semideciduous Atlantic Forest is one of the most diverse ecosystems in the world with a great diversity of spiders. Most spider-related studies in this ecosystem focused on species richness and composition...

Abstract A taxonomic revision of the genus Duthiea Hack. in India recognizes two species: D. brachypodium and D. bromoides. D. brachypodium is newly recorded here from the Indian Eastern Himalaya (IEH), collected from Si...

Two new cauliflorous species of Aristolochia subseries Anthocaulicae from southern Central America are described and illustrated. Aristolochia guanacastensis from northwestern Costa Rica resembles A. ruiziana, from which...

A key characteristic of most woody bamboos is the process of cyclical flowering after a long vegetative period. These flowering events are generally gregarious, affecting an entire region, and are followed by the death o...

Estudiamos la fenología y edad de madurez reproductiva y el tamaño y la frecuencia de la puesta de una población de Liolaemus gracilis de las dunas costeras de Buenos Aires, Argentina. Examinamos las gónadas de 93 ej...

Agricultural space is defined and determined in regard of natural, technical, economic and social deeds. The geographical aspect comprises soil types, topography, water distribution, eliminate flora and fauna; it determi...
