“…Approximately 26% of the total area is urbanized, while another 21% of the area encompasses a hilly area that is the Serra do Japi Biological Reserve. Important representatives of regional biodiversity are found in this reserve, as evidenced by a set of investigations already carried out there (Cardoso‐Leite, Pagani, Monteiro, & Hamburger, ; Carvalho, Macedo‐Godoy, Adania, & Esbérard, ; Lombardi, Carvalho, Biral, Saka, & Hieda, ).…”

In our study, we aimed to investigate the influence of landscape patterns on the diversity of birds in four urban parks. The parks are located in a region that has a high value of regional biodiversity and is also highly urbanized (Jundiai, state of São Paulo [SP], in Southeastern Brazil). Using a set of aerial photos, the surrounding landscape was divided into two regions (rings) and corresponding landscape metrics were calculated. The presence of bird species was recorded monthly over a one‐year period and classified according to selected ecological criteria. The land cover of the areas surrounding each park was primarily buildings and residences. Bird diversity was significantly correlated with the presence/proximity of water bodies. We state that the potential of the parks to harbor bird species is not negligible. Managing the area surrounding a park to increase the percentage of forested area and the size of forest fragments is as crucial as managing the core park area, especially for improving its attractiveness for new bird species.

“…Understorey small-seeded species have rarely been studied (Pereira et al 2009;Chen et al 2013) and few data are available to define a germination pattern. Herbs and shrubs represent 30% to 40% of all plant species in tropical forests, most of them with very small seeds (also called dust seeds) (Vieira & Pessoa 2001;Menini Neto et al 2009;Lombardi et al 2012;Rocha & Costa Neto 2019). In addition, comparison among small-seeded species from distinct microhabitats in the same study is not frequent (Ellison et al 1993;Andrade 1995;Chen et al 2013;Koutsovoulou et al 2014), limiting our understanding of the ecological relevance revealed by the physiological responses in laboratory experiments.…”

Germination of small tropical seeds has distinct light quality and temperature requirements, depending on microhabitat

The coexistence of plant species in tropical rainforests is related to specific abiotic resources, varying according to the occurrence microhabitat of each species. Light quality is the main abiotic factor influencing germination of small seeds; however, studies often do not discriminate its effect from that of light irradiance. This study compared specific requirements for seed germination of ten small-seeded species, with restricted occurrence in only one of three contrasting microhabitats: forest understorey, edge of clearings and open areas.• Laboratory experiments were carried out to test temperature regime (constant or fluctuating), light quality (R:FR) and light irradiance (PAR), which reproduce high and low conditions commonly found in the microhabitats.• Seed germination of all species occurred between 20 and 30 °C, only seeds of open area species were able to germinate at 35 °C and no species required alternating temperatures to germinate. Irrespective of species and microhabitat, a decrease in the R:FR reduced the germination percentage; however, there were differences in the capacity to germinate at low R:FR. The values of R:FR 50% were higher for open area and edge species (0.441-0.345) than for understorey species (0.181-0.109), with few exceptions. For all species and most of the tests, germination was not influenced by PAR.• Light quality is the most important light signal for germination of small seeds; irradiance has little effect. Our results suggest two distinct patterns of germination for smallseeded species: open area and edge species are light-demanding and require high R:FR to germinate, while understorey species are shade-tolerant and germinate at low R:FR. These differences are responsible for distinct microhabitat occurrence and help to explain the coexistence of species in tropical forests.

“…Estudos florísticos na Serra do Japi têm sido produzidos desde a década de 80 (Rodrigues et al 1989;Leitão-Filho 1992;Pansarin & Pansarin 2008;Andrade et al 2012;Lombardi et al 2012;Monge & Semir 2012;Vasconcellos-Neto et al 2012). Quanto ao conhecimento de Leguminosae para a área, apenas os resultados para a subfamília Caesalpinioideae já foram publicados (Escobar et al 2014).…”

Leguminosae clado mimosoide em um fragmento de floresta estacional semidecidual do sudeste do Brasil

A floresta estacional semidecidual, fitofisionomia que revestia quase todo o interior do estado de São Paulo, está representada atualmente por apenas 5% da sua cobertura original. Este trabalho consiste no levantamento dos representantes do clado mimosoide numa das últimas áreas de vegetação contínua do estado, a Serra do Japi. Foram registradas 24 espécies distribuídas em oito gêneros, dos quais os mais diversos são Mimosa (7 spp.), Inga (6 spp.), Senegalia (5 spp.) e Anadenanthera (2 spp.). As espécies de hábito arbóreo predominam no local e a maioria dos táxons compartilha o Cerrado e a Mata Atlântica como área de ocorrência, com exceção de Inga subnuda e Senegalia grandistipula, ambas endêmicas da Mata Atlântica. Seis são endêmicas do Brasil (Abarema langsdorffii, I. subnuda., I. sessilis, Leucochloron incuriale, Mimosa furfuracea, S. grandistipula), doze são novos registros para a Serra do Japi e uma é inédita para o estado (Senegalia tucumanensis). Os principais caracteres diagnósticos para a distinção dos gêneros foram os tipos de folha e fruto, presença de nectários extraflorais e número e fusão de estames, e para as espécies, presença de glândulas em locais específicos, presença de acúleos, tricomas e estípulas, e número de folíolos. Palavras-chave: Fabaceae, florística, Serra do Japi, São Paulo, leguminosas, taxonomia. AbstractThe semideciduous seasonal forest, physiognomy that covered almost the entire interior of the São Paulo state, is currently represented by only 5% of its original area. This paper presents a survey of mimosoid clade in one of the last areas of continuous vegetation of the state, the Serra do Japi. Twenty four species belonging to eight genera were sampled, of which Mimosa (7 spp.), Inga (6 spp.), Senegalia (5 spp.) and Anadenanthera (2 spp.) were the most diverse genera. The arboreal taxa prevail on this area. Inventoried species are well distributed in the different vegetation types of Brazil. Twelve species are new records for the Serra do Japi and one species to the state. Six species are endemic to Brazil (Abarema langsdorffii, Inga subnuda, I. sessilis, Leucochloron incuriale, Mimosa furfuracea, Senegalia grandistipula) and two only occur in the Mata Atlântica (Inga subnuda e Senegalia grandistipula).The main diagnostic characters to distinguish the genera, were the types of leaf and fruit, presence of extrafloral nectaries and number and fusion of stamens, and for the species, presence of glands in specific locations, presence of thorns, trichomes and stipules, and number of leaflets.
