Carabid beetles of tropical dry forests display traits that cope with a harsh environment [PDF]
, 2021 The tropical dry forest (TDF) ecosystem is characterised by strong seasonality exasperated periodically by the El Nino/southern oscillation (ENSO). The environment produced by this event could constrain the survival of small organisms, such as insects ...
