Pavonia fretensis sp. nov. (Malvaceae) from the Horn of Africa hotspot

Nordic Journal of Botany, EarlyView.
The new species Pavonia fretensis is described, illustrated by photographs and mapped. It occurs in coastal localities on both sides of the Bab al Mandab Strait and is known from southern Yemen, Eritrea and northwestern Somalia. The species differs from Pavonia rotundifolia from eastern Ethiopia and northern and central Somalia by having stellate ...

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

Plants, People, Planet
Societal Impact Statement Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere.

Guapira leucophylla (Nyctaginaceae, Caryophyllales), a new species from the northern Espinhaço Range of Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
Guapira Aubl. (Nyctaginaceae, Pisonieae) comprises dioecious shrubs and trees widely distributed in the Neotropics and occupying diverse habitats. In the Brazilian Cerrado, the genus occurs in several phytophysiognomies, including Campos Rupestres, a montane rock ecosystem with high levels of endemism but still marked by significant gaps in botanical ...

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

Nordic Journal of Botany, EarlyView.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

VARIACIONES INTERANUALES DEL POLEN ARBÓREO EN LA ATMÓSFERA DE MAR DEL PLATA EN RELACIÓN A LA FENOLOGÍA FLORAL. CASO ESPECIAL: QUERCUS (FAGACEAE)

Publicación Electrónica de la Asociación Paleontológica Argentina, 2010
Airborne pollen concentration in the Mar del Plata atmosphere was analyzed during two consecutive years. Also plant sources and flowering development was studied. Quercus was the selected taxon.

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Observing shifts in phenology of tropical flowering plants.

PLoS ONE
Changes in flowering can cause misalignment with pollinators and seed dispersers, thus causing changes in fitness of both the plant species and their mutualists.

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

Oikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Phenological and morphological variations of Oryza rufipogon and O. nivara in Sri Lanka and their evolutionary implications

Scientific Reports
Phenological and morphological variation are widely viewed as a pivotal driver of ecological adaptation and speciation. Here, we investigate variation patterns of flowering phenology and morphological traits within and between O. rufipogon and O.
